Hacksaws differ in size of cutting teeth. This indicator determines that, which will be res, for which species of wood the hacksaw is suitable and how convenient it will be to work with it. But, exept this, there are other indicators, which you need to pay attention to when choosing a tool. Therefore, the question, how to choose the right hacksaw for wood requires careful study.
Technical characteristics of a hacksaw on a tree
For a saw on a tree the basic value has:
- web width;
- canvas length;
- tooth size;
- handle;
- blade steel grade.
The length of the blade affects the width of the cutting workpiece, and also greatly facilitates the work. Long strokes allow less effort, because in one movement the incision is made by a large number of teeth. With, the longer the canvas, the stronger it will spring. Working with hardwoods, such as gum, maple or oak, the hacksaw will cause a lot of inconvenience, and will quickly blunt.
In terms of practice, short hacksaws, with a long cutting blade to 35 cm, best used for one-time small work. They are great for those, who lives in the apartment, because they do not take up much space. So, in the private sector, it is desirable to immediately choose a long hacksaw (50-55 cm). This will allow you to work with blanks, as well as sawing trees.
Usually, the width of the canvas has 10-20 cm. Narrower canvases are not allowed due to technical reasons (break even with a slight bend), wider ones are quite inconvenient to work with manually. Keep in mind when choosing a wood saw, that thin blanks are easier to saw with a narrower blade, and, vice versa, thick (roofing logs, tree trunk, etc.. P.) - wide.
Ordinary handles are made of plastic. It is best to choose a handle with a rubberized backing. This will protect your hand from calluses, and will allow you to perform a denser capture.
The saw tooth is the most important part of the tool, so at this point we will dwell in more detail.
Purpose and types of teeth
In hacksaws on a tree distinguish such types of a tooth:
- for universal cutting;
- for transverse cutting;
- for longitudinal cut.
Longitudinal incision is often made or jigsaw, or a circular saw. But there are also hand saws for these purposes. As in the version with power tools, tooth on a hacksaw looks like a hook. The angle between the tooth may be 45-60 degrees.
The form in the form of a hook gives the chance to make a cut only in one direction. It is best to cut along the fibers. In this case, the saw easily penetrates the wood and the cut is the most accurate and smooth. Buying this hacksaw is appropriate only for those people, who want to make furniture with their own hands. Because it is not suitable for any other purpose.
The tooth for a cross cut is the most popular. It looks like a triangle. The angle of the tooth is equal to 45-55 degrees. This design allows you to saw well as when moving the blade forward, and in the opposite direction. As a result, cross-cutting occurs without much effort, quickly and as accurately as possible. When choosing a hacksaw must be taken into account, that this type of tooth is suitable only for dry blanks. Fresh wood saw will break, and sharpening will spoil.
For fresh wood use triangular teeth with parallel sharpening. This means, that the teeth are sharpened in a checkerboard pattern and only on one side. As a result, a free canal appears between the teeth inside the incision, on which moisture sawdust will be able to leave freely, without complicating the advancement of the canvas.
The next option - combined teeth. Here triangles intersect with semicircles. And the semicircular tooth is larger, than triangular. As the canvas moves forward, long and narrow teeth make a guide incision, and when the canvas returns to its original position, the triangular tooth increases the incision channel and removes shavings and sawdust. We must not forget, that the smaller the angle between the triangular and semicircular tooth, the more accurate the incision will be.
It is desirable not to choose saws for universal cutting, usually, they have different compilation of teeth, which theoretically should do any job equally well. But in practice, these hacksaws blunt much faster, and their sharpening is usually more expensive, than a new saw.
And most importantly - in any quality saw teeth should be made of hot steel.
Types of hacksaws on wood
There are several types of beer, including:
- ordinary;
- narrow;
- Лучкова;
- with butt.
The cheapest saw for wood is a narrow hand hacksaw. This tool is suitable for sawing branches when working in the garden and small work with blanks. Usually, use or bilateral triangular teeth, or parallel sharpening.
You need to understand, that it is possible to work with this hacksaw only with preparations, no thicker 7-12 cm. Very short canvas does not allow you to create a lever, in accordance, sawing thick parts hurts to require a large load.
Ordinary saws can be with any type of teeth. The choice will depend only on that, for which tasks you plan to buy a tool. You just have to pay attention to that, that it is undesirable to work with these saws during furniture production. Or you need to buy special large stuslas, to be able to saw at a certain angle.
Butt saws are used as an auxiliary tool. Their main task - small cuts in detail.
Bow hacksaws are an analogue of an electric jigsaw. They allow you to make the most accurate cut and work with different workpieces at different angles. exist:
- transverse;
- sweeping;
- prickly;
- circular.
Swinging hacksaws make it possible to produce longitudinal cutting. Today there are paintings 40-80 see long. Longer workpieces can only be sawn with a power tool.
Cross hacksaws are used to cut workpieces across the fiber. They can make an incision, and at right angles, and under any other. And you get perfectly smooth edges in the section.
Circular hacksaws are narrower, are used for figured sawing. They are used to perform rounding and other complex elements. A characteristic feature is the use of very flexible steel grades.
Spiked hacksaws make it possible to perform simple geometric shapes on the workpiece.
The difference between bow saws is, that the mounting mechanism is purchased once, and are not spent directly on saws, buying new canvases.
Manufacturers of wood saws
Professional saws are characterized by good quality and compliance with these characteristics. Buying tools from proven manufacturers, you will be sure of that, that this product will serve you reliably and for a long time. Among the proven manufacturers should be highlighted:
- Stanley;
- Bahco;
- Sandvik;
- Gross.
Bahco is a Swedish company, part of SNA Europe. More than more 200 years of history, the company has never changed its basic concept - the production of quality and affordable hand tools. Bahco saws are characterized by durability, and a nice price.
Sandvik saws can also be found on the market. This company is part of Bahco, therefore, the quality of the product meets the general requirements of the company.
The American manufacturer drank Stanley, also emphasizes the availability of your product. The company has a large staff of engineers and designers. Thanks to their developments, cutting edge and saw blade differ from domestic GOST, but it does not affect the quality at all. This company is great for those, who chooses a hacksaw for the country. Because the combined large teeth make it possible to produce any type of cut.
The German firm Gross is younger than other companies. Competitiveness of the goods is reached thanks to very low cost. However, the products are quite high quality and meet all standards. The only drawback is that, that the choice of products is very small.
There are also domestic manufacturers, which offer quality and relatively inexpensive saws. Among which:
- Piranha;
- Bison.
Bison saws are made in China, however, meet the requirements for teeth and steel. Of the disadvantages:
- cannot be used to work with hardwood;
- time of constant work no more than 10 minutes (then pause 15 minutes);
- should not be left outside (rusts quickly, even at low humidity).
Despite this, characteristics of the hacksaw are suitable for pruning trees.
The Piranha company is relatively small and has been operating relatively recently. Like everything new, its products are quite affordable and of good quality. Piranha saws are presented in only a few versions. The big producer of this product is China. But the products of this company are covered with Teflon, which protects the hacksaw from corrosion, even in the case, when you forgot her on the street.
About safety and comfort
When choosing a hacksaw for wood, pay attention to the handle. The most convenient is a two-component handle with a rubberized insert. It provides a lasting delight, does not allow the palm to slide and does not rub the hand.
To work with different sized blanks and perform different types of cuts is not superfluous is a set of interchangeable webs. Often saws are equipped with equipment with different cutting edges and different shapes - for sawing branches, execution of cross and straight cuts, etc.. D. Also quite convenient, when the hacksaw is equipped with a cover for carrying and storage or at least a plastic cap, covering sharp edges, excluding injuries and damage to the surface of the canvas.
