Wood, as a building material, has numerous advantages, not the least of which is ease of processing. Various tools for working with wood are produced, however, the simplest and most common is the usual hand saw-hacksaw. What are the parameters for choosing a hacksaw for wood, which is better and what to look for when choosing a new tool?
Criteria for choosing a hacksaw for wood
The choice of the most convenient option is usually determined by a set of the following characteristics:
- web length;
- material used in the manufacture of the saw;
- handle configuration;
- shape, pitch, tooth size.
Even when changing one of the listed characteristics, the operational properties of the hacksaw also noticeably change. It is clear that the shape of the handle affects the comfort of working with the tool. Therefore, if you use the saw mainly one master, you need to select the handle so that, as they say, "lay down" in the hand. If you rarely use the hacksaw, and also not too intensively, then the comfort of retention is not the most important parameter.
Most often, hacksaws are produced with a blade length of 350 to 600 mm. The choice of the length of the blade depends on the expected thickness of the wood products that will have to be sawn. The main thing here is not to go to extremes, because a too short blade will have to work longer to achieve the same result, and a too long blade, especially when sawing hard wood, can spring and, again, create difficulties.
Blade material, pitch and types of tooth
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. In addition, the teeth can be hardened or not. Both options have their advantages. Unhardened teeth can always be sharpened with a certain skill. Red-hot teeth are more reliable, last longer, but it is unlikely that they can be sharpened after they wear out.
To the question which hacksaw for wood is best suited for certain conditions, most often you can answer based on the size, type, pitch of the teeth. Efficient cutting of wood materials is characterized by the speed and accuracy of cutting. These properties depend on each other. the accuracy of the cut guarantees a small tooth, while reducing the speed of work. Larger teeth speed up sawing, but cut surface quality and accuracy become worse.
For the right choice, the TPI parameter is important, which means the number of teeth per inch of the working length of the blade. This coefficient is usually indicated in the marking on the side surface of the canvas. For accurate work, where the accuracy and quality of surfaces are of great importance, TPI should be 7–11, if speed is preferable, then TPI is selected with a value of 3-5.

By the type of teeth, several types of hacksaws are distinguished:
- For longitudinal sawing. This tool has teeth in the form of an oblique triangle; it is used to cut wood along the fibers.
- The transverse hacksaw is equipped with isosceles triangular teeth, mainly used for dry wood.
- For mixed sawing. Triangular teeth alternate with semicircular. Not recommended for intensive, frequent use.
- With a trapezoidal tooth. Each tooth of this hacksaw has three cutting edges. The use of this hacksaw has undeniable advantages. the tool cuts quickly, without effort.
- The upgraded saw has grouped teeth separated by special gaps that make it easier to remove chips from the cutting zone.
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 shapes of handles. Price can also indirectly testify to the durability, as well as the quality of the performance of the instrument. A good hacksaw is unlikely to be the cheapest.
Information sellers about which hacksaws for wood are better sold, makes it possible to judge the most popular models. Let’s consider some of them.
Stanley Jet Cut SP2-15-288
This hacksaw is equipped with a D-shaped handle, a 50-centimeter blade with a tooth pitch of 7 mm. A tooth with three cutting edges makes cutting easy and fast.

The price is in the range of 1200–1300 rubles.
The tool is popular, wins due to reasonable cost (from 700 rubles), as well as versatility. Triangular hardened teeth allow longitudinal and transverse cutting at a fairly high speed. Special technology of tooth alignment eliminates the occurrence of clamping forces, improves productivity, work efficiency. Hardened, specially bred teeth in 5 mm increments, comfortable plastic handle. Web length from 40 cm.
Stanley General Purpose 1-20-089
Designed for accurate and accurate cutting of workpieces, this hacksaw has small teeth (TPI = 11), made using Jet Cut technology, an ergonomic handle, and a polished steel blade. A feature that can be considered accuracy provided by a small tooth. At the same time, the work speed is also quite high, due to the teeth with three cutting edges (sawing occurs both on the forward and on the reverse stroke). Convenient handle provides a firm grip, excellent control and ease of operation, attached to the canvas with three screws. Length 380 mm, price. 650-700 rubles.
BAHCO Laplander 396-LAP
An excellent tool designed for sawing dry and raw 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, teeth of the Sandvik XT form, allowing to saw both along and across the fibers. The canvas has a special coating, applied not only to protect against corrosion, but also to reduce friction. The length in the folded state is 23 cm, the weight is 200 g. The blade is securely fixed both in the folded and in the open position. The only drawback is the price. from 1.6 to 2 thousand rubles.
