Hacksaw for longitudinal cutting of wood. Hacksaw - the secrets of choosing the perfect tool

Every true master (even home) always has a convenient and multi-functional circular power saw. But sometimes there are such types of work when you need to saw off only one part, or simply perform small amounts of work, but you do not want to get an electric device. In this case, a hacksaw blade will help you out. But how to choose a good hacksaw for wood, which will be convenient to use and easily “cut through” any species of wood, we will consider further.

By right, a saw can be called the mother of all hand tools. From the moment people understood the importance of iron and created the first saw, the tool has changed many times and already has a dozen “sisters” that can do any kind of work.

Let's take a closer look at what each of these parameters should be.

Hacksaw blade - what should it be

The main part of the tool is the canvas. The first thing you should pay attention to when choosing a hacksaw for wood is the length of the blade. A lot will depend on this, at least even the possibilities in application.

At the same time, the larger the canvas, the stronger it will spring, which will complicate the process, especially when working with maple, ash and oak.

If you plan to cut the bars, or narrow rails, you will have enough tools from 25 to 30 cm long. When planning to use the tool for serious work in construction, give preference to tools with a blade length of 50 cm.

When choosing the length should be guided by the rule that the length should exceed the diameter of the workpiece exactly 2 times.

If you do not follow this recommendation, you complicate your work. The teeth of a short hacksaw will only jam in the wood, and moving such a saw to free it from sawdust will be very difficult.

Working in an uncomfortable environment will cause fatigue earlier than if you followed all the instructions.

Typically, the width of the hacksaw blade is from 10 to 20 cm. Models with a width of less than many disadvantages, as they are impractical and will immediately fail. But keep in mind that too wide tools will not give you comfort.

For the manufacture of hacksaws, alloy steel is used, which differs from the usual one in the high content of carbon and silicon of the following grades:

65G, 60 C2A.
8 XF, 9 XF, 9 XC.
Y7, Y7A, Y8, Y8A, Y8Г, Y8ГА, Y9A, Y10.

The metal is quenched by special exposure to a magnetic field, due to which a high-frequency electric current appears.

When spreading on the surface, it warms up the upper layer of metal, after which it is quenched with cold water. According to the standard, the hardness of the metal should be 45 НРС, but it is better to give preference to products whose hardness of the canvas will be from 55 to 60.

A high-density wood hacksaw will have good flexibility, but the teeth will be stable. Externally, when examining the quality of the tool, you will determine the dark shade of the sharpened teeth.

What should be the teeth

Another important factor in the performance of the tool and its work when cutting is the size of the teeth. An indicator such as sawing accuracy has the designation TPI, which means the number of teeth per inch (2.54 cm).

The relationship between this technical parameter is:

A cloth with larger teeth gives high speed when working, but in this case expect a sloppy and rough saw cut.
For hacksaws with small teeth, the cut will be clean and accurate, but the speed will be several times lower.

When you will determine the size of the teeth, focus on the type of material being processed.

When working with material such as chipboard. Where high accuracy of the cut is needed, you should take a tool with an index of 7 to 9, and for logs in the garden where the cleanliness of the cut does not play an important role, an indicator of 3 to 6 is suitable.

If we compare the ordinary and red-hot tooth, the difference will be that the ordinary does not stupid for a long time in domestic use. But the hacksaw with hardened teeth cannot be re-sharpened, therefore, when the quality of the cut decreases, you will have no choice but to throw it away.

The advantage of a conventional tooth is that it can be sharpened. This work is periodically carried out using a file marked with an accident ( for sharpening drank).For sharpening, you need to file several times on each tooth.

Depending on the type of teeth, there are three types of hand saws:

Some types of tools have teeth that resemble a trapezoid in shape. This decision made a new generation of hacksaw blades, which is durable and much stronger.

But it is worth considering that sharpening such a blade is a difficult task, since it is difficult to give shape to the shape of small teeth. This greatly reduces the tool life, at the end of which you will have to change the blade or choose another good hacksaw for wood.

Now on the market, new hacksaw models that are designed for cutting not yet dried have become increasingly common. Small chips easily pass between the cut teeth and do not impede work.

Narrow

This is a small saw, which is a flat, straight blade and handle. With its help, you will be able to perform a number of small works: cut curved parts, make a through cut, and so on.

It is made of a web with two-sided teeth in the form of a triangle, sometimes with parallel sharpening. The disadvantage of the tool is that when pressed during operation, the blade may deviate from the specified direction.

Standard

A hand saw with standard parameters can have any type of teeth and is most often equipped with several change blades, which have different designs and types of teeth. Despite the versatility claimed by the parameters, such saws are not suitable for the manufacture of furniture.

With a pickaxe

Both narrow and standard saws tend to bend when the stiffness threshold is raised. To avoid this, it will be effective to use a tool with a butt, which will be in the role of a stiffener. The presence of such a “latch” will not make it possible to make a cut larger than the width of the canvas, as it will prevent the passage of the canvas into the tree to a greater depth.

Luchkovaya

This type of saw is a more bulky device, which is a manual version of the jigsaw. Due to the fact that the design is thorough and its threaded connection of the handles, such saws can easily overcome knots, making a cut along the patterns and radii.

Depending on the intended type of work and design of the saw, there may be:

Transverse - for cutting across the wood fiber.
Swing - for cutting along.
Circumferential - for creating holes, rounding and sawing of a figured type.
Spike - for cutting connecting spikes and cutting simple geometric shapes on the workpiece.

Only a beam-type hacksaw can perform all these functions without additional tools.

The procedure for choosing is quite simple:

Now about the arms. Usually they are made of plastic. Prefabricated handles are made of two plastic halves, which are not very rigid. It is much more convenient to work with tools with a solid-cast handle equipped with a rubber backing for fingers. If you have a rubber insert, it will be much more convenient for you to make a grip, thereby enclosing yourself from the formation of corns.

Still on sale, you can often find a tool with a cross over and standard handle. The first option is convenient in that it is possible to replace the canvas with a new one in case of expiration of the useful life.

Keep in mind that not all saw models are sold sharpened, and how soon you can get started depends on this seemingly insignificant detail.

According to customer reviews, they won confidence:

It is very difficult to do on a private plot or cottage without a hand saw in wood. This tool also has the name "hacksaw". With this simple device, you can cut trees or branches in the garden, shorten fences and do many more types of work where you need to change the length of a wooden product: boards, laminate, and so on.

It is unlikely that anyone would seriously think about this, but if you make the right choice of a saw, then the term of its operation, as well as the convenience of work and the quality of the cut, will depend on it. That is why it is necessary to know all the basic parameters for the correct choice of such a carpentry tool.

Choose a saw

There is a wide variety of wood hacksaws in the markets and shops. They all differ in several parameters:

the shape and size of the teeth;
canvas size;
steel grade of which the cloth is made;
handle shape.

If one of the indicated parameters changes, then the saw-hacksaw will radically change its initial characteristics. All these factors must be taken into account when buying a tool for different tasks. And you should always make sure that saw very well sat in the master’s hand, because it will greatly facilitate the work. You should not buy a tool with a small pen to a person who has big hands. Such a hacksaw will be very inconvenient to use, and therefore the cut quality will suffer.

Tooth size

This option will greatly affect the speed of work, as well as quality. To conveniently determine the size and number of teeth, a TPI designation has been specifically introduced, which should indicate the number of teeth in one inch. Such a parameter can always be found in the tool description, and also this value is very often drawn directly on the canvas.

Large tooth hacksaw will provide a rough cut, as well as high speed. This parameter will be needed for cutting large boards, firewood and branches. TPI of such an instrument is 3 ... 6.
If there is a need to make a neat and even cutthen you need to buy a saw with small teeth - T PI 7 ... 9. This hacksaw is ideal for sawing chipboard, fiberboard, laminate. But it is worth noting that productivity will be much less than that of a large-toothed hacksaw.

Joiner's saw is selected according to the size of the teeth. For processing ordinary wood, you can buy large or small, and for delicate materials such as fiberboard it is better to purchase a fine-toothed saw. There are several designations in stores: for drywall, for wood, and so on. The difference lies in the same tooth size. For each material, the optimal size will be selected.

The teeth can also vary in shape, and this will affect the purpose of the tool:

For longitudinal sawing the cloves are made triangular in shape with oblique corners. Their appearance will resemble hooks that are sharpened from 2 sides. Such a saw will slide along the wood fibers and produce a cut very smoothly, without leaving a notch.
For cross cutting teeth are made in the shape of an isosceles triangle. This type of hacksaw is sawed when passing back and forth, but it is advisable to use it only on dry wood.
Sometimes it is necessary to use a mixed type of sawing, and for this option, two types of teeth are ideal, which are alternately arranged one after the other. Long curved ones will cut the materials in the forward direction, and triangles during the reverse movement will expand the channel and hook the sawdust and shavings.

Steel

Nobody needs a saw to break down after several uses, and therefore it is advisable to choose the highest grades of steel. The teeth can be plain or red-hot. Ordinary are sharpened at home.

Saws with red-hot teeth are disposable, because when they wear out, you can’t do anything on their own. This kind is very easy to detect by dark color. It is advisable to choose a saw that is made of stainless steel, because often in garages it can be very damp, and therefore the saw will be covered with unnecessary corrosion. And often there are situations when work is carried out on the street, but after using the saw, it is forgotten on the site, then it rains, after which the tool is also covered with rust.

Blade length

This parameter will be determined by the pitch of the teeth and the size of the saw.

Small hacksaws are equipped with small and frequent teeth, the length of the blade will not exceed 350 mm.
Universal hacksaws are available with an average tooth size, and the length of the entire tool is no more than 550 mm.
On a wide hacksaw there are large teeth and an increased pitch, the length of the blade is usually not more than 600 mm.

The canvas can vary not only in length, but also in shape. A traditional saw is usually narrowed on one side of a rectangle. This suggests that you have acquired a universal tool with which you can cut various objects. A rounded sheet is usually used to cut branches or other objects from a distance. Such a hacksaw is very light and glides on wood with high quality, without causing much trouble to the owner.

Lever

Thanks to the handle, the convenience of any work is carried out. The tool should ideally sit in the hand, and also be very convenient. To make a pen use different plastics that will be pleasant to the touch. When choosing, make sure that the material will not slipif the hand sweats during operation. It is for this purpose that special grooves and indentations are made in the handle, as well as rubberized pads. It is these parameters that all manufacturers take into account, and therefore produce products that differ in a wide variety of pens.

Varieties

In modern stores and markets there is a huge variety of saws for any purpose. Therefore, in order to understand which tool is useful to you, you must first familiarize yourself with all of their types.

Proper selection

As already found out, there is a wide variety of saws, but the choice of a hacksaw should also be carried out in accordance with certain types of work:

For longitudinal sawing, you must use a swing saw.
Lateral well copes with wood, where there is a transverse arrangement of fibers.
Tenon can cut various grooves and spikes, as well as technological recesses in the tree.
Circular saws holes of various shapes.
A folding hacksaw is used on trees.

The choice should always be made for the main purpose for which a particular tool is purchased. For a household, a saw with interchangeable blades is suitable, and it is also desirable to have several types of cutting tools at home.

It is very difficult to master all the information and choose exactly the saw that is suitable for a particular situation. That is why it is advisable to study some more tips that will help you choose the right hacksaw.

Which wood hacksaw is better? You should not ask such a question, because each tool is useful for a specific situation. Therefore, you need to know how to choose a hacksaw for wood depending on the purpose. By following these simple rules, you can easily find the right tool that is right for you.

In the arsenal of the home master there will always be a functional and easy-to-use circular power saw. But there are situations when it is required to saw off a part and perform a small amount of woodwork, and there is no time or desire to deploy and connect the unit. In these cases, the hand saw is excellent at saving. But how to choose a hand hacksaw for wood, so that it is convenient to use and easily “cuts through” any wood species, we will consider in more detail.

Saw is considered to be the ancestor of a large family of hand tools. Since the creation of the first type of tool out of iron, the saw has undergone many changes, having managed to acquire numerous "sisters" capable of performing dozens of jobs.

In the household, it is impossible to do without "toothy helpers": they are indispensable for trimming the garden, small carpentry and carpentry

Hand saws on wood differ in many ways: blade size, steel grade, tooth shape, handle design. Let us dwell on each parameter in more detail.

What should be a hacksaw blade?

The main part of the tool is a hacksaw blade. The first thing you should pay attention to when choosing a product is the length of the canvas. The possibilities of its application largely depend on this parameter. At the same time, the longer the canvas, the more it springs, which also complicates the process, especially when working with hardwoods, such as ash, maple or oak.

A long stroke makes it possible to apply less effort when sawing, because a single number of cuts are carried out with a large number of teeth

For sawing small elements such as skirting boards, bars or narrow rails, you can do with a hacksaw with a blade length of 25-30 cm. When planning to use the tool for more serious construction work, choose a product with a blade of 45-50 cm.

When determining the length of the hacksaw blade, follow the rule so that the length of the saw exceeds the diameter of the processed elements by 2 times. If you do not follow this recommendation, you only complicate your work. The teeth of a short hacksaw will jam inside the wood, and in order to advance the tool to free them from sawdust, everyone will have to make a lot of effort. Uncomfortable work will cause premature fatigue.

Traditionally, the width of the web of the product varies in the range of 10-20 cm. Models with a narrower web are not allowed for technical reasons, because they fail at the slightest bend. But it is worth considering that too wide canvases are inconvenient for manual work.

Of no less importance is the fabrication material of the web, in the role of which alloy steel most often acts, as well as its degree of hardening

For hacksaws, tool alloy steel with a high content of silicon and carbon grades is used:

65G, 60 C2A;
8 HF, 9 HF, 9 HS;
U7, U7A, U8, U8A, U8G, U8GA, U9A, U10

The metal is quenched by exposure to an alternating magnetic field, at which a high-frequency electric current appears. Spreading over the surface, it heats the surface layer of the metal, which hardens after cooling.

A metal hardness of 45 HRC is considered a standard parameter, but it is still preferable to choose products with a hardness of 55-60 HRC. A hacksaw with a high hardness blade will have sufficient flexibility, but at the same time high tooth stability. An external examination of such a tool can be determined by the darkish shade of the sharpened teeth.

Parameters of teeth on the blade

The decisive indicator of the productivity of the tool and the accuracy of cutting wood is the size of the teeth.

The teeth of a hacksaw for woodwork have a dual function: they cut wood and at the same time remove sawdust

Sawing accuracy is determined by TPI - the number of teeth per inch.

There is an inverse relationship between these technical parameters:

canvases with large teeth set a high speed of work, but the saw cut turns out to be rough and sloppy;
fine-tooth hacksaws guarantee a clean and precise cut, but at a relatively low speed.

When determining the required tooth size, you should focus on the type of material being processed. For example, for working with chipboard, where high cutting accuracy is required, choose a tool with a high TPI of 7-9, and for sawing logs and gardening where the cleanliness of the cut is not so significant - TPI of 3-6.

When choosing the best option for the hacksaw, follow the rule that the minimum thickness of the log should in any case be greater than the step of three teeth

If we compare red-hot and ordinary tooth, then the difference lies in the fact that in the first embodiment, subject to domestic use, the product does not stupid for a long time. But a hacksaw with a hardened tooth cannot be sharpened again. When she starts to cut badly, she will just have to throw it away.

An ordinary tooth can be sharpened. Periodically, it can be performed using a special file marked with an accident (for grinding saws). To sharpen the canvas, it is enough to perform several movements on each tooth.

Depending on the type of teeth used, three types of hacksaws are distinguished:

For longitudinal sawing. The products are equipped with teeth in the form of an oblique triangle and look like hooks. The tool allows you to cut wood along the fibers. Such saws have a sharpening on both sides of the tooth, due to which they are capable of cutting both when moving forward and in the opposite direction.
For cross cutting. The teeth of the tools are made in the form of isosceles triangles. Such a design makes it easy to saw the material both when holding the cutting edge forward and in the opposite direction. But this type of tooth is only suitable for working with dry workpieces, but not with fresh wood.
For mixed sawing. Products have a combined composition in which triangular edges are combined with slightly elongated semicircular notches. This solution allows you to forward the semicircular teeth when moving the arm forward, and expanding the channel when triangular returns, removing chips and sawdust from it.

Some types of modern tools are equipped with teeth that are made in the shape of a trapezoid. This solution allows you to make the canvas more durable and wear-resistant.

But it is worth considering that it is very problematic to sharpen such a blade, since it is difficult to give the desired shape to the trapezoidal teeth. This significantly reduces the service life of the product, after which it is necessary to change the canvas or purchase a new tool.

For cutting fresh branches, it is more convenient to use blades equipped with triangular teeth processed with parallel sharpening, in which each element is sharpened only on one side and staggered

Often on the market you can find a modernized look of hacksaws.

Upgraded hacksaws can be easily distinguished by groups of teeth located on the canvas, between which the gaps are clearly visible

Upgraded type hand saws are effective for cutting raw wood. Wet chips through the intervals between the teeth in the process of cutting easily comes out of the cut, without hampering the movement of the tool.

Types of hand saws on wood

A small narrow saw is a structure that consists of a straight, flat blade and handle. She performs delicate work: through cuts, curved parts are cut.

This type of tool is designed for cutting wooden workpieces, the thickness of which does not exceed 8-10 cm, sawing small branches and small works in the garden

In the manufacture of narrow models, manufacturers install blades with triangular double-sided teeth, or with parallel sharpening. The disadvantage of the tool is that when pressed during operation, the canvas is able to deviate from a given direction.

Option # 2 - Normal

A standard hand saw can be equipped with any type of teeth and is often equipped with interchangeable blades of various types and designs.

To be able to saw off workpieces at a certain angle using a standard hand saw, you have to purchase special miter boxes

But despite the declared universality of their use, it is not advisable to use saws of this type in the manufacture of furniture.

Option # 3 - with a pickaxe

Both narrow and conventional saws are prone to bending with increasing rigidity of the processed material. In these cases, it is effective to use canvases equipped with a lug that acts as a kind of stiffener.

Hand hacks equipped with a snap are designed to create shallow cuts in a wooden surface of any thickness

The presence of a pickaxe does not allow the saw to make a depth incision larger than the width of the blade, since it prevents the cutting blade from passing further into the tree.

Option # 4 - onion

Saws of the beam type are more bulky devices, acting as an analog of a jigsaw.

The main purpose of this type of saws is to create an accurate cut when working with surfaces located at any angle

Due to the solid construction and threaded joints of the handles, beam-type saws are able to easily overcome knots by cutting along radii and curved patterns.

Depending on the purpose and design of the saw can be:

swing - for slitting;
transverse - for sawing workpieces across wood fiber;
circumferential - for cutting holes, making rounding and figured sawing;
tenon - for cutting connecting spikes, as well as cutting simple geometric shapes on the workpiece.

Only a hacksaw-type hacksaw can cut the material up and down, sawing blanks with complex lines and doing the work alone without involving an assistant.

The procedure for choosing a hacksaw for wood is quite simple:

Determine the purpose for which the tool will be used. For carpentry work, choose products with small teeth that provide high precision cutting, for carpentry - blades with large teeth.
Frequency of use. If the hand saw will be used only for one-time work, choose a tool with red-hot teeth. The service life of this type of product is quite large. In addition, you don’t have to worry about sharpening and cutting teeth during operation.
The uniformity of the canvas. Inspecting the tool, try to bend the blade carefully, setting the angle to 30-45 °, and then release it. Re-inspect the sheet: the slightest deviation at the bend point even within 2 mm indicates a poor quality metal.
The cost of the product. As with the choice of other tools, keep in mind that high-quality models of leading brands are always an order of magnitude more expensive than consumer goods. This overpayment is a kind of guarantee of the wear resistance and durability of the saw. But for one-time work, there is no point in wasting money on an expensive tool.

Conventional handles are made of plastic. Prefabricated plastic handles made of two halves do not have sufficient rigidity. It is much more convenient to work with a tool having a one-piece handle, which is equipped with a rubberized substrate for the fingers. The presence of a rubber insert allows you to make a tight grip, preventing the formation of corns in the palm of your hand.

Pay attention to the design of the tool handle: it is desirable that it has an ergonomic shape that allows you to correctly transfer force to the blade

On sale there are products with standard and flip handles. The second option is convenient in that it allows you to replace the worn canvas with a new one if necessary.

Keep in mind that not all hand saws go on sale already sharpened. And from this seemingly trifle, much depends on how soon you can get to work.

Many hacksaw companies are represented on the market. Judging by the reviews, they recommended themselves well: the hacksaw "Bison" of domestic production, Gross Piranha of joint German-Chinese cooperation, Irwin Xpert made in the USA. They are famous for their decent quality at a low price, which varies between 10-20 cu

Without a hacksaw, it is impossible to imagine a professional carpenter or carpenter, and in everyday life it is used quite often. The widespread use of this tool has contributed to the emergence of its various types, intended for certain operations.

To choose the hacksaw correctly, you should study its characteristics, imagine what you need to saw with it and how often it will be used.

Kinds

Like any common tool designed to perform a large number of work, a wood hacksaw is classified according to several parameters.

By type of cut and purpose

Hacksaws can be designed for cross cutting, longitudinal (swinging) or be universal. Between themselves, these species differ in the shape of the teeth.

The teeth of saws intended for longitudinal cutting of wood have the form of an oblique triangle. The angle between them is from 45 to 60 °, which allows sawing wood in only one direction, while ensuring an accurate and even cut line. Most often they are used in the manufacture of furniture.

Hacksaws with teeth resembling an isosceles triangle are used for cross cutting wood. Sharpening at an angle of 45-55 ° makes it possible to cut workpieces both in the forward and in the opposite direction. Most effectively, such a saw works on a dry tree.

The universal hacksaw has two types of teeth - triangular and semicircular (with semicircular more triangular). When the saw moves forward, long teeth set the direction, and wider, triangular, widen the cut, which allows sawdust and shavings to freely exit. The smaller the angle between these teeth, the more accurate is the incision.

Depending on the purpose, hacksaws for wood are classic, circular and spike. Classic saws are used for longitudinal or transverse cutting of wood. Circular hacksaws for wood are designed for cutting holes. Using tenon saws, elements are formed to connect the individual parts.

Tooth size

One of the main parameters of any hacksaw for wood is the size of the teeth. By size is meant a step, that is, the distance between adjacent tips. Depending on this parameter, the saws may have teeth:

small ones;
medium;
large.

Hacksaws with small teeth (from 2.0 to 2.5 mm.) Provide cutting wood with high accuracy and are most often used to work with products of the smallest sizes.

Saws with large teeth (from 4 to 6 mm) are used for cutting logs or beams.

Hacksaws with an average tooth size (from 3.0 to 3.5 mm) are used when machining parts that are small in size.

There are also types of hand saws on wood with teeth arranged in groups of 6-7 pieces, separated by gaps. Raw wood is treated with such a tool. Due to the available gaps, wet chips do not clog the cut channel.

Design Classification

Structurally, hacksaws for wood are:

narrow

They cut workpieces with narrow hacksaws, the thickness of which does not exceed 10 cm. They are also used for sawing branches of the garden, cutting curved parts and other works. Structurally, these saws are a narrow blade with triangular teeth connected to the L-shaped handle.

The standard hacksaw blade (GOST 2615-84) can have any kind of teeth. Often they are equipped with sets of removable canvases designed to perform a wide variety of carpentry and carpentry.

When processing hardwood, hacksaw blades can be very bent. Saws, the blades of which are equipped with a lug that acts as an additional stiffener, are spared from this drawback. However, its presence does not allow to make a cut deeper than the width of the blade itself.

The hacksaw with an award looks like a planer. It has two handles and is used in cases where it is necessary to perform grooves or spikes. Moreover, the depth of these elements may be different.

A beam saw is a canvas stretched on a base made in the form of a large arc. It is connected to the handle by means of a threaded or tension connection, which allows the use of different types of blades during operation. In turn, this makes it possible to single-handedly cut blanks having complex cutting lines.

In the market you can also find folding hacksaws for wood. They are very light and small in size when folded, which allows outdoor enthusiasts to take them with them on a camping trip or fishing. Such a saw has a short pointed blade with small teeth.

Other varieties

There are other types of wood hacksaws. Among them, there is a garden hand saw equipped with a narrow blade, for the manufacture of which chromium steel is used. It is equipped with widely spaced teeth tilted toward the handle. It is convenient to work with such a tool in cases where the emphasis during cutting has to be done on oneself.

There is a two-handed saw with which it is convenient to cut large logs or cut down trees. Two people should work with her.

The chain hand saw is a short chain with red-hot teeth and two handles at the ends. It is compact and suitable for hiking. You can work with it as one person, or together.

A modern and universal tool is an electric saw, with which you can perform a large amount of various work. In some cases, it completely replaces the circular. Changing the blade, they saw it, not only wood, but also plastic, metal.

main parameters

The effectiveness of using a hacksaw on a tree largely depends on its technical characteristics. The main ones are:

the material from which the saw blade is made;
the length of the canvas and its shape;
size and shape of the tooth;
view of the handle.

When choosing a tool, you need to pay attention to each element of the characteristic. Only in this case you will not have to regret buying.

A modern hacksaw blade is made of wood from high-quality tool (alloy) steel with a high content of carbon and silicon (65G, 8HF, U7 ... U10). The hardness should be at least HRC 45. There are also models that use a combined, more wear-resistant blade with a cutting part (teeth) having increased hardness (HRC55 ... 60).

The length and shape of the canvas

In the domestic market you can find wood hacksaws with a length of 250 to 650 mm in increments of 25 mm. This parameter is specified by GOST 2615-84 and depends on the distance between the teeth.

Note! It is necessary to choose a saw, guided by the rule: "The length of the blade should be 2 times the thickness (diameter) of the workpieces."

Otherwise, it will be uncomfortable to work with a hacksaw, since a short canvas will jam inside the solid wood.

As a rule, hacksaws with a narrow blade have a length of not more than 350 mm and are equipped with a large number of small teeth. Universal tools are equipped with canvases about 500 mm long with medium teeth. Hacksaws with a wide blade are made with large teeth located at a great distance from each other (large step), their length can reach 650 mm.

Traditionally, a saw on a tree has the appearance of a triangle narrowed on one side. Such a tool can work with any kind of wood. In addition, there are hacksaws adapted for work, for example, with tree branches or other objects located at a certain distance from the saw cutter. They have a rounded shape and are light in weight.

Tooth size and shape

The size of the teeth (step) of the hacksaw blade directly affects the performance and accuracy of the tool. The larger the teeth, the higher the speed, but the accuracy and quality of the cut is deteriorating. The use of a saw with small teeth, on the contrary, guarantees a clean and even cut, but at the same time the speed drops.

The accuracy of the cut is determined by the number of teeth per 1 inch of blade length (TPI coefficient), that is, their density. Its value is marked on the side surface of the web (for example, 7x1 ″ or 7TPI). The larger the TPI, the smaller the step. So, 2TPI \u003d 12 mm, and 12TPI \u003d 2 mm.

When choosing a hacksaw for wood, it must be borne in mind that the minimum thickness of the workpiece must be greater than the step of three teeth.

Essential when working with a hacksaw on a tree is the form of sharpened teeth. In this case, teeth that are sharpened on both sides and have the appearance of an acute-angled or isosceles triangle are considered standard.

Important! The latest generation of saws is equipped with irregular shaped teeth. They have the appearance of a trapezoid and are distinguished by the presence of three sharpened faces and increased wear resistance. Canvases with such teeth do not lend themselves.

Handle type

The type of handle and the material from which it is made largely determine the convenience of working with a hacksaw on wood. It is best to work with a saw equipped with a one-piece plastic handle with rubberized finger inserts. The two-part handle is less comfortable since it does not have sufficient rigidity.
