Sometimes we need to cut a wooden plinth at home or trim the garden . Therefore, the household has to have a hacksaw on the tree.
But even this simple, at first glance, tool has many variations, differing not only in the manufacturer and price, but also with such important characteristics as the length of the canvas, the size of the tooth, the type of handle and steel.
How to choose a hacksaw on wood?
Of course, first of all you need to pay attention to the quality of the canvas - the steel grade, the hardening procedure and the quality of the grinding. From these basic conditions will depend on the ease of operation of the product, as well as its service life.
The standard hardness of the metal for hacksaws on wood is 45 HRC and 55 HRC for the teeth. This type of hacksaw refers to the flexible and wear-resistant. They are easy to recognize by a darker shade of teeth in comparison with the rest of the canvas. However, these hacksaws can not be sharpened. Edit and sharpen only those saws in which the teeth are made of rolled steel.
As for the length of the canvas, its choice depends on your needs. If you plan to cut small blocks and boards, 30 cm is enough. But when building and having a dacha, it is advisable to get a saw with a length of the linen of 45-50 cm and more.
In general, depending on the length of the saw blade, you can use this way of counting: the length of the hacksaw should be equal to two lengths of the largest billet that you will be sawing. This ratio makes it possible to efficiently remove sawdust during sawing due to the complete exit of the hacksaw teeth in the process. And it will be easier for the hands when excessively sweeping movements will be absent.
The next criterion for choosing a saw-saw on wood is the size of the teeth and their sharpening. This parameter will determine the speed and accuracy of the cut. The smaller the tooth, the more accurate the cut, but the lower the speed, and vice versa. Hacksaw on a tree with a large tooth will contribute to less fatigue, but the cut will be more rough.
If you need a hacksaw for cutting trees, the model with a small tooth is undesirable, since the cleanliness of the cut is not so critical in this case, but the cutting speed and the effort expended are very important. In this case, a distance of 4-8 mm is sufficient.
If you need a sharpened saw, buy a traditional saw with triangle teeth. Modern models with trapezoidal teeth after blunting are subject to change entirely or only in part of the canvas. However, with this they are endowed with greater strength and durability.
Important when choosing a hacksaw and such a characteristic as the ergonomics of the handle. This will determine your comfort during work.
Folding wood hacksaw
This type of hacksaw is common among tourists and residents of city flats, when there is no need for a large saw, besides it is extremely inconvenient to store and carry it with you.
Folding saws occupy very little space, because they are easy to store and carry, besides, there is no need for a cover, because the dangerous part with the teeth securely hides in the handle.
A small folding saw can be sawed with a tree trunk with a diameter of up to 14 cm. So with quite simple tasks of clearing a path or harvesting firewood for an evening fire, it is quite manageable.
Also, such a saw is irreplaceable for small repairs in an apartment, for example, if you need to prepare a frame of wooden beams before the balcony paneling and in other similar situations.
Summarizing
So, choosing a hacksaw on wood, you need to determine the goals and the expected frequency of its application, which will determine the size of the blade and the distance between the teeth.
In any case, choose a quality product, durable and wear-resistant, so that the purchase becomes pleasant and useful.
