How to choose a hacksaw

A hacksaw is a must-have tool in almost any home. Sawing various wood parts or processing garden trees is a common thing, so it’s quite difficult to do without a special tool. To find a good and high-quality product, first of all, you need to figure out how to choose the hacksaw correctly. This tool has a lot of varieties that differ in some details and build quality.


When choosing tools it is recommended to focus on 4 main factors: the size of the blade, the size of the teeth, the type of metal, the shape of the handle.

Despite the simplicity of the device hacksaws for wood materials, in the question of their choice, you need to be savvy and have the necessary knowledge. Otherwise, there is a chance to get an inconvenient or poor-quality tool. In addition, it should be remembered that hacksaws can be sold in a stubble manner. In other words, you will not be able to start work immediately after purchase. Below is considered how to choose a hacksaw for cutting wood materials with a description of all the nuances that are worth paying attention to when choosing products.

Basic instrument characteristics

Saw classification

Saw classification.

First of all, you should look at the instrument with its orientation to its main part - the canvas. Comfort of operation and durability of the device depend on the quality of the metal, its production and proper sharpening. When selecting quality products, you need to focus on 4 main factors:

  • web size;
  • tooth size;
  • type of metal;
  • handle shape.

Of paramount importance is the size of the canvas. Its length is selected based on the purpose of the application. For narrow slats, wooden plinths and planks, a saw is suitable, the length of which ranges from 25 to 30 cm. If you decide to build a building yourself, it is advisable to pick a hacksaw from 45 to 50 cm.

The main criterion when choosing the length of the canvas is the diameter of the tree for processing. The size of the hacksaw should exceed it at least 2 times. You can purchase a tool of slightly shorter length, but problems may arise during operation. The main difficulty will be the jamming of the web inside the wood, since the teeth will not be released during cutting to drop sawdust. The second reason is the lack of comfort. In other words, you will spend much more physical strength on the sawing, because the muscles will be more tense due to the sweeping movements of the body.

Sharpening a handsaw

The size and accuracy of the cut depends on the size and sharpness of the teeth. When choosing a tool, you need to consider that the smaller teeth are designed for high-precision cutting, but they have some limitations in performance. With large teeth, sawing is not so neat for the sake of high-speed work, that is, you will spend less energy on sawing.

This property is marked on tools as TPI (total number of teeth per 1 inch). The accuracy of the cut depends on the value of this indicator. For example, when working with these types of boards, such as chipboard, you should use a hacksaw with a TPI of 7-9. This will allow the material to be sawed carefully without crushing its surface.

If a tool is purchased for fileing trees, then there are no requirements for accuracy of work. In this case, the main criterion is the performance of the tool, so the most suitable option will be a saw with a TPI of 3 to 6, where the interval between the teeth is 4-8 mm.

Preparing a hacksaw for work

Preparing a hacksaw for work: a - tooth separation; b - sharpening.

The standard teeth on the blades are triangular. Most of these teeth can be eaten away from time to time. Modern tools have trapezoid shaped teeth. In the process of their production, bias is made for high strength and resistance to wear. Such a saw cannot be sharpened, because during processing it is rather difficult to give the teeth the necessary shape. In addition, the high-strength metal from which they are made is difficult to grind. Therefore, after the end of the service life, the hacksaw will have to buy a new tool or change the blade.

The metal used for saws also has its own indicator. The classic hardness of the steel intended for cutting trees is 45 HRC. Metal is used for the teeth with a hardness of 55 to 60 HRC. Such tools at the same time combine wear-resistant teeth and a flexible base. Hacksaws with inherent characteristics are easily identified visually, because the blade has a lighter shade in relation to the teeth. Most of these saws can not be sharpened. Exceptions are only models with teeth that have not passed the quenching stage.

Lastly, attention should be paid to the handle, since only the ease of use of the tool depends on it. Handles are either flip or standard. In the first case, it is possible to replace worn cloth.

How to choose a hacksaw?

First you need to figure out for what purpose a hacksaw will be used: in carpentry or carpentry. In the first case, the tool produces high-precision cutting and is used for dry wood. The speed of work in carpentry is not as important as accuracy.

The length of the blade is chosen with an orientation on the purpose of the application, that is, on the size of the wood for sawing. For passive use, it is better to choose a hacksaw with red-hot teeth, since it will often be idle. Due to the long service life of such saws, you will not need to sharpen them, which in itself is a time consuming process.

The quality of the product is easily determined in the process of its acquisition.

You need to take the tool and first of all evaluate the uniformity of the canvas. After that, you need to bend it about 30-45 ° and release. Do it carefully, because you can break the poor-quality material. Then reevaluate the uniformity. If a slight deviation appears at the bend, the product metal is of poor quality.

Tool teeth have 2 tasks:

  • sawing wood;
  • remove sawdust.

If the location of the teeth on the canvas is rare, the productivity of the tool increases, and the sawdust does not clog the place of processing. Saws with a TPI rating of up to 7 are considered high-speed and comfortable to use. However, their disadvantage is the low accuracy of the cut.

Therefore, you need to focus on your own needs and look for the ratio of indicators that suits you. The best option for all types of work is selected as follows: the minimum diameter of the treated wood should have a size greater than the segment in which there are 3 teeth. Otherwise it will complicate the process of cutting, and you will quickly get tired.

Tools for cutting can be cut both along and across. The teeth of the saw, designed for cutting along, have a small slope. She cuts the wood away from her. The size of a standard tool is no more than 50 cm, the angle of the teeth is always sharp. Cross-saws are much more common, they can be found in any building stores in a wide range. Their teeth are ground in both planes. This allows you to cut wood movement on themselves and from themselves.

Important in the selection of tools for cutting wood has its value. There is a standard pattern here: expensive and branded models are of high quality, unlike fakes from China. If you need a hacksaw for one-off work, buying a branded model is not necessary. But for long-term operation, it is recommended to look at high-quality hardened steel products.

As a rule, good products are made of high-grade steel, which is processed using advanced technological solutions. It takes into account many details, ranging from the shape of the teeth and ending with the interval between them.
