tree like building material, has numerous advantages, not the least of which is ease of processing. Issued various instruments for working with wood, but the simplest and most common is the usual hand saw-hacksaw. What parameters are used to select a hacksaw for wood, which one is better and what to look for when choosing a new tool?

Criteria for choosing a hacksaw for wood

Choice of the most convenient option, as a rule, is determined by a set of the following characteristics:

• length of the canvas;
• the material used in the production of the saw;
• handle configuration;
• shape, pitch, tooth size.

Even if one of the listed characteristics changes, the performance properties of the hacksaw also change noticeably. It is clear that the shape of the handle affects the comfort of working with the tool. Therefore, if only one master will use the saw, you need to select the handle so that, as they say, it “fits” in the hand. If you use a hacksaw rarely, and also not too intensively, then comfort of holding becomes not the most important parameter.
Most often, hacksaws are produced with blade lengths from 350 to 600 mm. The choice of blade length depends on the expected thickness wooden products, which will have to be cut. The main thing here is not to go to extremes, because with a blade that is too short you will have to work longer to achieve the same result, and a blade that is too long, especially when sawing hard wood, can spring back and, again, create difficulties.

Blade material, pitch and tooth types

The material for the production of hacksaw blades is usually tool or alloy steel. In order for the tool to serve for a long time, you should choose a saw with a blade made of high types of steel, preferably stainless steel. The price will be higher, but it will certainly pay off. Additionally, the teeth may or may not be hardened. Both options have their merits. Unhardened teeth can always be sharpened with certain skill. Hardened teeth are more reliable and last longer, but it is unlikely to be possible to sharpen them after they are worn out.

The question of which wood hacksaw is best suited for certain conditions can most often be answered based on the size, type, and pitch of the teeth. Efficient cutting wood materials characterized by cutting speed and accuracy. These properties depend on each other - cutting accuracy guarantees a fine tooth, while reducing the speed of work. Larger teeth make cutting faster, but cut surface quality and accuracy become poorer.

For the right choice The TPI parameter is important, meaning the number of teeth per inch of working length of the blade. This coefficient is usually indicated in the markings on the side surface of the canvas. For accurate work, where the accuracy and quality of surfaces are of serious importance, the TPI should be equal to 7–11, but if speed is preferred, then the TPI is selected with a value of 3–5.

There are several types of hacksaws based on the type of teeth:

1. For longitudinal sawing. This tool has teeth in the shape of an oblique triangle and is used for cutting wood along the grain.
2. The cross saw is equipped with isosceles triangular teeth and is mainly used for dry wood.
3. For mixed sawing. Triangular teeth alternate with semicircular ones. Not recommended for intensive, frequent use.
4. With trapezoidal tooth. Each tooth of this hacksaw has three cutting edges. The use of this hacksaw has undeniable advantages - the tool cuts quickly and effortlessly.
5. The modernized saw has grouped teeth separated by special spaces, which make it easier to remove chips from the cutting area.

Hacksaws, in addition to the shape and arrangement of the teeth, are divided according to the shape and length of the blade, are folding, with various forms handles. The durability and quality of the instrument can be indirectly indicated by the price. Good hacksaw It's unlikely to be the cheapest.

Popular models

Information from sellers about which wood hacksaws sell best makes it possible to judge the most popular models. Let's look at some of them.

Stanley Jet Cut SP2-15-288

This hacksaw is equipped with a D-shaped handle, a 50 cm blade with a 7 mm tooth pitch. A tooth with three cutting edges ensures ease and speed of sawing. The excellent Swedish steel used in the production of the blade ensures high quality tool. The teeth are practically not subject to wear, which allows for many years of successful use. Price - within 1200–1300 rubles.

Stanley General Purpose 1-20-089

Designed for precise and accurate cutting of workpieces, this hacksaw has fine teeth (TPI=11) made using Jet Cut technology, an ergonomic handle, and a polished steel blade. A special feature is the precision provided by the fine teeth. At the same time, the operating speed is also quite high, due to the teeth with three cutting edges (sawing occurs in both forward and reverse motion). The comfortable handle provides a firm grip, excellent control and ease of use, and is attached to the blade with three screws. Length 380 mm, price - 650–700 rubles.

BAHCO Laplander 396-LAP

An excellent tool designed for sawing dry and wet wood, designed and manufactured specifically for hunters, fishermen and tourists, although it is also used by gardeners and even builders. Excellent Swedish quality, TPI=7, Sandvik XT shaped teeth, allowing sawing both along and across the grain. The canvas has special coating, applied not only to protect against corrosion, but also to reduce friction. Folded length -23 cm, weight 200 g. The blade is securely fixed in both the folded and open positions. The only drawback is the price - from 1.6 to 2 thousand rubles.

There is still no such tool as a hacksaw for wood, or you experience a lot of inconvenience when working with it, it’s time to correct the situation and purchase good saw, understanding in detail all the characteristics of the tool.

Wood hacksaws differ in blade size, steel grade, shape of teeth and handle. Now about each aspect in more detail.

Fabric characteristics: length, width, hardness

Particular attention should be paid to the hacksaw blade. From him quality characteristics depend cutting capabilities the saw itself. If the blade is long, then when sawing hard wood: oak, ash or maple, difficulties will arise, since the blade will spring back, which will require more effort to get the job done.

When it is necessary to carry out work on sawing small elements: skirting boards, slats, a blade length of up to 30 cm will be sufficient. To saw thicker bars or even logs, you will need a tool with a cutting part length of at least 45 cm.

Here is the simplest rule for determining the optimal length of the blade, which will minimize the effort expended when sawing: the length of the cutting part should be twice the thickness of the part being cut. A hacksaw that is too short will constantly get stuck inside the element being cut, and you will quickly get tired.

As for the width of the canvas, we choose the golden mean. If it is too narrow, there is a risk of breaking the tool when bending it, and inconvenience will arise when working with a blade that is too wide. The width should be between 10 and 20 cm.

The hacksaw blade is made of tool alloy steel, grades U10, U8GA, U8G, U8A, U8, U7A, U7, 9 HS, 8 HF, 9 HF, U9A, 60 S2A, 65G.

The acceptable parameters for the hardness of the alloy of the cutting part of the saw are considered to be 45. But still choose a blade that has high hardness parameters: 55–60 HRC. Such a tool has the necessary flexibility and at the same time strong teeth. These teeth have a characteristic darkish tint.

Determined by teeth

We are interested in the size of the teeth. There is such a coefficient: “TPI” (the number of blade teeth per inch). For example, to work with chipboard, the TPI should be around 7-9 (meaning 7 to 9 teeth per inch). If the work to be done is mainly garden work: sawing logs, branches, then sparser teeth are also suitable - from 3 to 6 teeth per inch.

Saw blades with sparse and large “teeth” can set a higher cutting speed, however, at the same time, the cut area will be chipped. A blade with a larger number of teeth and a smaller size, on the contrary, leaves behind a clean cut, without burrs, but the operating speed is quite low.

Don’t rush to conclude that the best hacksaws for wood have hardened teeth. Indeed, at home, using such a tool for a long time does not lead to tooth wear. However, it will not be possible to sharpen them again. When the teeth become dull, all you have to do is throw the tool away.

But an ordinary, unhardened tooth can be sharpened. To sharpen a saw, just take a special file, marked with a three-letter abbreviation: Accident (for sharpening saws), and run it over each tooth.

Video: saw sharpening technique

There are several types of hand saws:

• Longitudinal. Has an oblique tooth. When viewed from the side, it looks like a hook. Used for sawing large wooden elements along the fibers. The teeth in such saws are sharpened on both sides, which makes it possible to cut not only in one direction.
• Transverse. It has a tooth in the shape of an isosceles triangle. The sharpening is double-sided. This makes it possible to cut in two directions. Suitable for sawing dry wood only.
• For mixed sawing. It has triangular-shaped teeth, replaced by elongated, semicircular teeth. This shape of the edge of the blade allows you to effectively cut with semicircular teeth when moving forward, while triangular teeth, when moving backward, expand the cutting furrow, while removing sawdust and shavings formed at the cutting site. Intended for infrequent use.
• Trapezoidal. Has three cutting edges. Manual sawing with this type of teeth - a pleasure - without extra effort, fast and easy. However, sharpening this type of tooth is very difficult, and in some cases impossible.
• Modernized. The teeth are located on the edge of the blade in groups, with characteristic spaces between them. Used when sawing raw wood. The spaces between groups of teeth allow wet chips to easily exit the cutting zone without clogging the cutting edge.

The following types of hacksaws can be distinguished:

	Narrow. Designed for smaller work: sawing curved elements made of wood no more than 8–10 cm thick. Very convenient for working in the garden for removing small branches.
	Regular. A blade of this type may contain different types of teeth, both modernized and trapezoidal. The convenience is that the canvas is replaceable. However, due to inaccurate cutting, use in manufacturing work wooden structures not recommended.
	With a butt. This is the name cutting tool received due to the characteristic stiffening rib that runs along the edge of the upper part of the canvas. This allows you to avoid unwanted bends of the cutting part of the hacksaw when working. They are used in work where it is necessary to make shallow and neat cuts in the workpiece.
	Luchkovaya. It is somewhat reminiscent of a jigsaw, which can easily make a curved and precise cut, even in the presence of knots.

There are also saws:

• Sweeping. Used for longitudinal cut.
• Transverse. Used for cross cutting.
• Circular. Used when making holes and curved cutting.
• Spiked. Used for cutting connecting tenons.

The most popular among tourists is the folding saw. It looks like a large folding knife, with a serrated blade that snaps into the handle. Firstly, you don’t need a special case, and secondly, such a saw takes up little space. Such folding saws are able to saw through a tree trunk up to 14 cm, which makes it an indispensable tool on long hikes.

So, we looked at the main types of hacksaws for wood: in terms of their purpose and characteristics, they are very different from each other. Therefore, before you buy a tool of one type or another, ask yourself a few questions:

1. For what purposes? If for carpentry work, then the blade should have a fine tooth. If you do carpentry - with a large one.
2. How often will it be used? If from time to time, it is better to take it with a hardened tooth.
3. What is the quality of the metal? Bend the canvas at an angle of 30–45º, then let it straighten out again. If after this it does not visually return to its original position, then the quality of the metal of the cutting part of the hacksaw leaves much to be desired.
4. What is the price. If a product is expensive, then it is not consumer goods. It is better to pay for wear resistance and durability than to simply throw away the saw, and at the same time the money. However, for infrequent use, you can take a cheaper tool.

You should also not forget about the tool handle when choosing a saw. It is better to buy a tool with a solid handle, which, as a rule, has a rubberized insert for the fingers. Such rubber backings allow you to make your hand grip tighter, which will protect you from the appearance of calluses.

Video: technical characteristics of hacksaws for wood

What are the differences between a high-quality and a bad hacksaw? Low quality can be seen by poorly sharpened teeth. Sometimes manufacturers cheat and make the teeth seem sharp, but after a few jobs they become dull. A good hacksaw, on the other hand, is made of steel that will hold its edge for a long time. The review contains a rating best hacksaws for woodworking, the features of choice and function are indicated.

Purpose

The main purpose of a hacksaw for wood is cutting wooden materials. Blade, teeth, handle included. The blade is the working part of the tool. Sawing wood is divided into several types. The first is the separation of dry materials into parts, that is, boards, logs, plywood and other rubbish. The second type is pruning the garden, improving other trees. The following materials are also processed:

• bars;
• laminate;
• plywood;
• polystyrene foam;
• aerated concrete;
• foam concrete.

Criteria for choosing a hacksaw for wood

When choosing, you should be guided by the following criteria:

• the size and shape of the teeth, as well as their pitch length;
• handle configuration;
• what material can be sawed (oak, cherry, brushwood);
• canvas length.

The comfort of work will be influenced by the shape of the handle. This parameter is the main one during intensive training. To avoid rubbing calluses, use gloves.

Length and size of the canvas

The average length of the canvas is from 350 to 600 millimeters. The choice depends on the thickness of the tree you plan to cut. Try to choose a medium length. For example, if you cut with a blade that is too short, you will spend more time cutting, and if you cut with a blade that is too long, it will begin to spring back after half the distance.

The length should be 2 times the diameter of the workpieces. At the same time minimum thickness The workpiece should have a pitch of three teeth.

Tooth size and shape

The entire work process depends on this parameter. There are hardened/unhardened teeth. Unhardened teeth can always be sharpened if the owner has certain skills. Hardened teeth are more reliable. Once worn, they cannot be sharpened.

The teeth are divided into small, medium, and large. Cutting speed/accuracy - this parameter determines the degree of efficiency of wood cutting. High precision work is ensured by fine teeth. A large tooth is ideal for cutting materials quickly, but this will compromise accuracy and quality.

For products of the smallest sizes, teeth ranging in size from 2 to 2.5 mm are used. They provide high cutting accuracy.

Medium-sized teeth ranged in size from 3 to 3.5 mm. Large teeth can be used to cut logs. Their length ranges from 4 to 6 mm.

Differences between incisors in appearance

There are several types of wood saws. They are determined by appearance teeth:

• Performs the functions of longitudinal sawing. These teeth are used to cut trees along the grain. The teeth will be in the shape of an oblique triangle.
• For dry wood, use a cross saw.
• Triangular teeth are suitable for occasional use. These teeth are regularly replaced with semicircular ones. Suitable for mixed sawing of wood.
• For high speed For work, it is recommended to purchase a saw with trapezoid-shaped teeth. The owner will cut quickly and not get tired.

Design

The design comes in a variety of configurations and sizes. So, the following structures are distinguished:

• Narrow - saw small workpieces that are no more than 10 mm thick. Curvilinear parts and branches in the garden are also cut out. A blade with narrow triangular teeth is installed here.
• Standard hacksaw. Any teeth can be installed. They are equipped with replaceable sets of canvases. This is convenient when performing carpentry work.
• Hacksaws equipped with a backing are protected from strong bending.
• The award-winning hacksaw has two handles. A bit like a plane. Designed for cutting grooves in wood.
• The blade in the form of an arc is presented on a bow-type hacksaw. Excellent help where complex cuts need to be made.
• Folding hacksaws with small teeth are suitable for hobbyists active recreation. They are positively assessed by tourism/fishing enthusiasts. They differ from other types in lightness/compactness. Outwardly it resembles a folding knife.

Other types:

• Garden hand saw.
• Two-handed saw for two people (transverse).
• Chain hand saw for hiking trips.
• Electric hacksaw.

Handle type

This parameter determines the ease of use of the tool. If the handle is made of two parts, then use will be less comfortable, since it does not have a sufficient level of rigidity.

Universal or hand saws are equipped with reversible handles, where blade changes are required during operation. Next, let's look at which hacksaw for wood would be better.

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

To choose the right hacksaw, you should study its characteristics, imagine what exactly needs to be cut with it and how often it will be used.

Species

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

By type of cut and purpose

Hacksaws can be designed for cross cutting, longitudinal cutting (swing) or be universal. These types differ from each other in the shape of their teeth.

The teeth of saws designed for longitudinal cutting of wood have the shape of an oblique triangle. The angle between them ranges from 45 to 60°, which allows you to cut 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 in both forward and reverse directions. This saw works most effectively on dry wood.

A universal hacksaw has two types of teeth - triangular and semicircular (whereas semicircular ones are larger than triangular ones). When the saw moves forward, the long teeth set the direction, and the wider, triangular ones widen the cut, which allows sawdust and shavings to escape unhindered. The smaller the angle between these teeth, the more accurate the cut.

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

By tooth size

One of the main parameters of any hacksaw for wood is the size of the teeth. By size we mean pitch, that is, the distance between adjacent points. Depending on this parameter, saws may have teeth:

• small;
• average;
• large.

Hacksaws with fine teeth (from 2.0 to 2.5 mm) provide cutting of 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 medium tooth sizes (from 3.0 to 3.5 mm) are used when processing parts that do not have large sizes.

There are also types of hand saws for wood with teeth arranged in groups of 6-7 pieces, separated from each other by intervals. This tool is used to process raw wood. Thanks to the existing gaps, wet wood chips do not clog the cutting channel.

Classification by design

Structurally, hacksaws for wood are:

• narrow;
• standard;
• with butt;
• with a reward;
• archery;
• folding.

Narrow hacksaws are used to cut workpieces whose thickness does not exceed 10 cm. They are also used for sawing branches in the garden, sawing out curved parts and other work. Structurally, these saws are a narrow blade with triangular teeth connected to an L-shaped handle.

The blade of a standard hacksaw (GOST 2615-84) can have any type of teeth. They are often equipped with sets of interchangeable blades designed to perform a wide variety of carpentry and joinery work.

When processing hard wood, hacksaw blades can bend greatly. Saws whose blades are equipped with a backing that acts as an additional stiffener are free from this drawback. However, its presence does not allow making a cut deeper than the width of the blade itself.

A hacksaw with a reward looks like a plane. It has two handles and is used in cases where it is necessary to make grooves or tenons. However, the depth of these elements may vary.

A bow saw is a blade stretched over a base made in the form of a large arc. It is connected to the handle using a threaded or tension connection, which allows the use of blades during operation different types. In turn, this makes it possible to single-handedly cut workpieces with complex cutting lines.

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

Other varieties

There are other types of wood hacksaws. Among them, a garden hand saw is distinguished, equipped with a narrow blade, for the manufacture of which chromium steel is used. It is equipped with widely spaced teeth inclined towards the handle. This tool is convenient to use in cases where you have to focus on yourself while cutting.

There is a two-handed saw that is convenient for sawing large logs or felling trees. Two people should work with it.

A chain hand saw is a short chain with hardened teeth and two handles at the ends. It is compact and suitable for use on backpacking trips. You can work with it either by one person or by two people.

Modern and universal tool– an electric hacksaw, with which you can perform a large volume of various works. In some cases, it completely replaces a circular saw. When changing blades, they use it to saw not only wood, but also plastic and metal.

Basic parameters

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

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

When choosing a tool, you need to pay attention to each element of the characteristic. Only in this case you won’t have to regret the purchase.

Canvas material

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

Length and shape of the canvas

On the domestic market you can find hacksaws for wood 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.

Pay attention! 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 workpiece.”

Otherwise, working with a hacksaw will be uncomfortable, since the short blade will jam inside the solid wood.

As a rule, hacksaws with a narrow blade are no more than 350 mm long and are equipped with a large number of small teeth. Tools for universal use are equipped with blades about 500 mm long with medium-sized teeth. Hacksaws with a wide blade are made with large teeth located on long distance from each other (large step), their length can reach 650 mm.

Traditionally, a wood saw has the shape of a triangle narrowed on one side. This tool can work with any type of wood. In addition, there are hacksaws adapted for working, for example, with tree branches or other objects located at some distance from the sawyer. They have a rounded shape and are lightweight.

Tooth size and shape

Tooth sizes (pitch) hacksaw blade directly affect the performance and accuracy of the tool. The larger the teeth, the higher the speed, but the accuracy and quality of the cut deteriorates. Using a saw with fine teeth, on the contrary, guarantees a clean and even cut, but at the same time the speed decreases.

The cutting accuracy 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 canvas (for example, 7x1″ or 7TPI). The higher the TPI, the smaller step. So, 2TPI=12 mm, and 12TPI=2 mm.

When choosing a hacksaw for wood, you must take into account that the minimum thickness of the workpiece should be more step three teeth.

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

Important! The latest generation of saws are equipped with hardened teeth non-standard shape. They have the shape of a trapezoid and are distinguished by the presence of three sharpened edges and increased wear resistance. Blades with such teeth do not yield.

Handle type

The type of handle and the material from which it is made largely determine the ease of working with a hacksaw on wood. It is best to work with a saw equipped with a solid plastic handle with rubberized finger inserts. The handle, made of two parts, is less comfortable, as it does not have sufficient rigidity.

The Zubr Expert saw is a universal tool that can be used to carry out both longitudinal and cross cuts of wood. The blade is 40 cm long and has hardened teeth, set in a special way, located in 5 mm increments.

The Banco Laplander 396-LAP mini-file is specially designed for use in hiking conditions. The narrow, pointed blade has Sandvik XT-shaped teeth, which ensure high-quality cutting of wood both along and across the grain. The length of the hacksaw when folded is 23 cm, and it weighs only 200 g.
