Joiner work in our time is difficult to imagine without electrical tools. Circular saws, cordless jigsaws and machine cutters allow you to create high-quality cutting at a high working pace. Nevertheless, hand tools remain relevant, due to the ease of use and complete non-volatility. A special place in this segment is occupied by a saw blade - at first glance, a kind of hacksaw with an unusual device, but in practical use, significant operational differences can be noted.
Tool Features
The design of the saw is formed by the same basic components - a cutting metal blade and a handle. The principal feature of the device can be called the presence of that very pickaxe. This is an overhead part on the upper part of the web that acts as a stiffener. What is this supplement for? A traditional hacksaw during sawing gives small fluctuations in the blade, which slows down the work and can affect the quality of the result. In order to minimize "hanging out", manufacturers increase the rigidity of the canvas by increasing its thickness. The negative effect of such a change in parameters will be the expansion of the cut area, which is unacceptable in the delicate processing of small structures and parts. In turn, the saw blade is precisely due to an additional device with increased stiffness eliminates the effect of oscillation, while maintaining a moderate thickness of the blade. This tool also differs in a small red-hot tooth, which allows for precise and accurate cuts.
For what work is the saw with a pickaxe intended?
This version of the hacksaw is difficult to attribute to ordinary household models. Nevertheless, it is a specialized tool that is used in the furniture industry and in the creation of decorative wooden products. In the household, such a saw can perform connecting grooves when installing wooden structures. Moreover, it should be borne in mind that the blade precisely because of the stiffener imposes restrictions on the depth of cut. In this sense, a surface selection from a solid wood or the formation of small holes can be considered as the target operations of a saw blade. Why is such a tool needed in construction? When installing door and window frames, this hacksaw will allow you to make complex connecting edges, spending a minimum of time. Likewise, when laying wooden floor coverings, it may be difficult to select at the points of passage of communications - a thin canvas with a small tooth can easily cope with such tasks.
Attachment Saw Characteristics
In the manufacture of the fabric is usually used high-strength steel alloy, protected from corrosion. The handle is made of a wooden base or rubberized plastic. In terms of cutting capabilities, the following characteristics are significant:
- The length of the cutting area is from 250 to 350 mm.
- The width of the canvas is an average of 70 to 100 mm.
- Tooth pitch - from 3 to 4 mm.
- Web thickness - 0.8 mm.
An important parameter is the angle at the base of the handle. If ordinary wood saws have a direct continuation of the blade, then the shape of the edge models allows you to make slopes of 45-90 degrees. This is also a way to increase the ergonomics of the tool when doing custom cuts. There are versions with constant angular fixation at a certain degree, but there are functional modifications with the ability to adjust over a given range.
Combination of wood saw and miter box
Every carpenter knows how important it is to correctly fix the working base in the process of cutting. In the case of a hand tool, the importance of fastening becomes completely decisive regardless of the characteristics and type of hacksaw. The device in the form of a miter box is optimally suited for obushnyh models. This is an auxiliary device designed to create precise cuts - including corner cuts. The design of the device resembles a box with slots and a ditch. Through the elongated holes in the process, the web will pass, and the central part will serve to accommodate the workpiece. To choose a saw blade for the miter box should be possible cutting with different angles - at 45, 60 and 90 degrees. But this value is not fundamental, since most designs have a universal purpose. The material of manufacture and the parameters of the miter are more significant in terms of compatibility with the processed material.
Tool manufacturers
The segment is highly specialized and not in great demand among a wide audience, therefore not every manufacturer addresses it. The best developments are offered by KRAFTOOL, IRWIN and Bahco. So, in the family of the first company, a 320 mm Multi-M hacksaw with a rounded top is presented. This version is suitable for rigid sheet blanks made, in particular, from combinations of wood and plastics. IRWIN implements a 300 mm Xpert XP3055 hacksaw. The small design with a two-component handle is ergonomic, reliable and safe. As for Bahco, its product range stands out with a Superior saw blade with original NXT teeth, which are subjected to high-precision hardening. This model is suitable for medium and small workpieces of different hardness. The thickened butt increases the resistance of a thin blade and increases the quality of cut.
Finally
Non-standard tool designs quite logically increase the cost. If an ordinary household hacksaw costs an average of 300-500 rubles., Butting modifications from the above manufacturers are available for 1500-2000 rubles. Accordingly, the question arises of how much carpentry special-purpose hand tools are needed for the ordinary home craftsman? Of course, there is no question of regular use. But for those who, in principle, deal with wooden structures, the presence of such a saw in the household will not be superfluous. Another thing is that its function with the same quality can also be performed by jigsaws and specialized narrow hacksaws. The difference will only be in the details of the technological organization of the workflow.
