Peculiarities

There are various options for hand-hacksaws, but the main (or most common) of them are full-frame, which use 12-inch or 10-inch blades. Regardless of the type of hacksaw, it is important to make sure that a high-quality tool made from a special alloy steel is purchased.

In more modern models, the blade can be adjusted by length, which allows to remove branches of various thickness. The cutting element is placed in the pillars that are on the frame. Many people do not understand that it is possible to establish it in different positions for your own needs. The blade is simply moving to the left-right or up-down.

Among the huge range of products offered, all models differ in the form of handles, dimensions, sizes of teeth and other parameters. Buyer should consider their own needs when choosing a web material and its size. If it is supposed to cut the boards and remove small branches, then you should pay attention to the tool that has a width of the metal cutting part ranges from 28 to 30 centimeters. For construction purposes, a canvas are used from 45 to 50 cm, but you can find on the market and more – it all depends on what work is planned to perform.

The effectiveness of the tool depends on the proportions, so the wooden blank the thickness must be two times less than that of the hacksaw. In this case, more swinging movements are obtained, therefore, the task is fulfilled faster. Large teeth are obliged to fully enter the material – only so sawdust will be deleted.

From how much the handle produced, the convenience of the user will depend on the user during operation. This element of construction is attached behind the blade, sometimes you can find on sale a pistol type handle. The handle is created from two materials: wood and plastic. In more expensive versions, it can be rubberized, which significantly improves the interaction of the hand with a surface.

Another feature that can distinguish tree hacksaws among themselves, is the firm and the size of the cutting teeth. If you look at, the pointed elements never stand in each other, because in this case the tool will immediately get stuck in the material. To simplify the task, the teeth give a different form, which is used and for various options to cut:

  • longitudinal;
  • transverse.

Tools with teeth for longitudinal cutting used to work along wood fibers. Main distinctive feature – Each pointed element is quite large and sharpened at right angles. The tool seems to cut wood, working on the principle of the chisel.

To silent across, take another unit, which has every cloth at an angle. There are also Japanese teeth, which are narrow and very long, and at the top of the canvas are pondering the cutting edge with a double tilt. You can find on sale and a universal tool that can be used in both cases. His teeth are sharpened symmetrically.

Purpose

Depending on the number of teeth, the instrument is determined on the working facility – it will be used for heap or for cutting. As a rule, you can see this feature in the instructions or description to the tool. On some models, the manufacturer has embossed the necessary parameters directly to the surface of the working path.

Large teeth indicate that hacksaw is used for fast and coarse cut. As a rule, this is the main tool of summer houses and gardeners, because without it can not do in the household. Through such a hacksaw, you can cut firewood, remove thick extra branches in the fall. The instrument should stand marking 3-6 TPI.

If the description of the tool is worth TPI 7-9, it means that such a hacksaw should be used for better cutting, where accuracy is important. The main scope of application – work with laminate, fiberboard and chipboard. Due to the small size of the teeth, the user spends more time on the cut part, but it turns out to be smooth and without jar.

Stolyes acquire a whole set of tree hacks, because each is used to solve a certain task. In a tool for longitudinal cutting, the teeth are always performed in the form of triangles whose angles are bevelled. If you look at, such a form something likes the hooks that have sharpened on both sides. As a result, the slice is flat, the cloth penetrates into the material tightly. For those teeth, which allow to make transverse cutting, the form is very similar to an equilibried triangle. Use such a hacksaw is allowed only on a tree that is completely dry.

In the combined version, the teeth of two types are used, which are followed by each other. Sometimes in the design of the cutting canvas there are intervals or emptiness, thanks to which the spent material is given.

Varieties of tree hacksaws

Hacksaws are presented in a wide range, They can be divided into three large groups that possess their own classification:

  • with volat
  • to create curvilinear cut;
  • Japanese.

Wood-hacksaws: species and characteristics

    If it is planned to perform a thin work, then it is necessary to use a tool with a trap that, in the upper edge of the canvas, an additionally installed a strip of brass or steel that impedes bending. These hacks are classified as follows:

    • nipsens;
    • with a swallow tail;
    • with a shifted handle;
    • edge;
    • Model.

    Wood-hacksaws: species and characteristics

    The first on the list are the largest, because their main purpose is to work with thick boards and firewood. Equipped with a closed handle form, which is ideal for convenient fixation of the instrument in hand. Reduced version of this model – Swallow tail – used to work with solid wood.

    If you have to work with through spikes, then you should use a knob with a knob. The user can adjust the element, while it is convenient to work both right and left hand.

      If necessary, perform a thin cut not to find a better tool than the edge saw that has compact sizes. But the smallest of all the presented options for this tool is a model leg.

      Any of the described models a person must start working on himself, holding the hacksaw under a small angle.

      If necessary, cut the curvilinear part, used a completely different tool. This category also has its own classification:

      • Loan;
      • openwork;
      • Lobzik;
      • narrow.

        Basic hacksaw usually has a length of 20-30 centimeters, while on the cutting canvas is provided from 9 to 17 teeth of one size per inch. It is possible to rotate the cloth in the required direction so that the frame does not interfere with the review. There are Folding Tourist Motors on sale that have little space.

        In the openwork peeling, the working surface reaches a length of 150 mm, and the frame is made in the form of an arc. The main sphere of use – artificial material and solid wood.

        As for the jigsaw, its frame is also made in the form of an arc, but deep, since the tool is necessary for creating strong bends in a thin material, for example, veneer.

        Narrow hacksaw is still known in the professional world as a spinning, because it is used in the middle of the wooden billet. The cutting element is very thin and the end is narrowed. It is thanks to this form that it is possible to create curves with a large angle. The design includes a pistol type handle on which you can clipped the desired canvas.

        Professionals know that this assortment of hacksaw is not limited, because there are still edged Japanese, about which not every newcomer could hear. Their classification includes:

        • cataba;
        • dose;
        • roba;
        • Mavashibiki.

          The main distinguishing feature of all these hacksaw is that their blades work on themselves. The cloths on the canvas are very tight to each other, so the cut is obtained narrow, without serious breakdowns of wood fibers.

          Kataba has cutting elements located on the one hand. You can use the tool for both longitudinal and transverse cuts, so it is considered universal. In comparison with the described model, the robination of the cutting canvas for transverse sawing is on the one hand, and the longitudinal one – on the other. When working with such a tool, it is worth keeping it under a slight inclination.

          For neat and thin sawing, the dose. Closer to the knob of the teeth smaller in size, which makes it easier to work.

          Wood-hacksaws: species and characteristics

          The narrowest knuckle of the listed variants of this group – Mavashibiki. All actions using such a tool must be dragging – it is possible to reduce the likelihood of blade deflection.

          The step of the teeth at the hacks can be from 14 to 32 teeth in. With the development of technical progress, this tool has moved from the category of manual classics and began to be manufactured by electric. In the design of electrical hacks, there is a powerful engine that gives the required power to drink branches.

          The highest power has stationary silent vertical machines, but some portable models are also not inferior. Power depends on the type of power. Rechargeable inferior in stationary electric, but they can be used even where there is no possibility to connect to the network.

          Also separately in the category of the described instrument costs award-forward – product with thin web not more than 0.7 mm. The cutting part is saturated in a block made of wood, very tight. Used one or two hands for small saws or inscriptions.

          Dimensions of teeth saws

          This parameter is one of the most important because it determines the scope of the use of the tool.

          Large

            Large is the teeth of 4-6 mm. Their distinctive feature is that they create a rough cut, but takes less time to work. It is best to use such a tool with big blanks, for example, logs, where the quality and subtlety of the lines are not so important.

                Types of Steel

                Made hacksaws of any type of steel of various species, including doped or carbon. The quality of the product says the hardness of the canvas – it is checked according to the Rockwell method.

                Challenged blades of hacksaws are made of tempered high-quality tool steel. They are very solid, but in some situations there are poorly susceptible to the load on the bend. Flexible blades contain tempered steel only on the teeth. Razilovka – flexible sheet metal. They are sometimes called bimetallic blades.

                Early blades were made of carbon steel, now called “low-alloyed”, and were relatively soft and flexible. They did not break, but quickly wear out. Over the course of several decades, the metal canvas changed, various alloys were used, which were tested in practice.

                Wood-hacksaws: species and characteristics

                High-alloyed metal blades were cut exactly, but were extremely fragile. It limited their practical application. The softer form of this material was also available – it had high resistant to loads, greater resistance to breakage, but was less rigid, so it was bent and as a result, a less accurate sawt was obtained.

                Since the 1980s, bimetallic blades began to be used actively in the manufacture of wood hacksaws. The advantages were obvious – there was no risk of breakdown. Over time, the price of the product fell, so such cutting elements are used as a universal version everywhere.

                Carbon steel is usually the most mild and cheap among other types. It began to be used in the manufacture of household tools. The material is valued by the masters, because it can be easily sharpened. Most wood processing tools are made of carbon steel, since another material is sometimes quite expensive.

                Wood-hacksaws: species and characteristics

                Stainless steel undergoing heat treatment, the coefficient of its hardness – 45. Used for making tools with high-quality cutting edge. Can be operated in difficult conditions, but it is more expensive than carbon.

                High-alloyed widely used in the production of tools. It is available in various versions: M1, M2, M7 and M50. Among them, M1 is the most expensive variety. Although few of the hacks are made of this material, the described type of steel can withstand longer operation. Not used for the manufacture of large tools due to inherent fragility. Hamsaws made of high-alloy steel, often labeled HS or HSS.

                Carbide steel using carbide is used in the manufacture of manual tools, since it allows you to perform tasks efficiently. Being very solid, the alloy is thoroughly treated so that it can be used to further use, because products can easily break.

                Most often steel hacksaws made of high-speed steel. The most popular will be BS4659, BM2 or M2.

                Rating models

                From domestic producers want to highlight Model series “ENGOR”, Which is made of carbide steel. One of the best representatives is the Model “Enek 19183”, the distinctive feature of which is the size of the teeth total in 2.5 mm. The tool is supplied on sale with a comfortable handle and hardened teeth, which speaks of a large operational product.

                It is impossible not to allocate Japanese saws, for example, Model Silky Sugowaza, which is used for the most difficult work, since its teeth is 6.5 mm. Gardeners and summer houses prefer to acquire such a tool for the formation of the crown of fruit trees, when you want to work quickly, without applying a lot of effort. A special form in the form of an arc makes it easy to cut unnecessary branches.

                Swedish hacksaws are not lagging behind in quality from domestic. Among them allocated Brand Bahco, who has proven itself thanks to high quality. In the universal tool category, the ERGO 2600-19-XT-HP model is highlighted, used for medium thickness blanks.

                How to choose?

                Experts give their recommendations about, What is worth paying attention to the consumer when choosing for a high-quality tool of this type.

                • Before buying a hacksaw, the user should pay attention to the material from which the hacksaw blade was made. Best if it is steel m2, because it has not only an attractive service life, but also worthy reliability.
                • When choosing, the diameter of the workpieces of wood blanks is required, since when buying hacksaws with a smaller size of the canvase, the user will have to make more effort during operation.
                • For cutting firewood and other rough work it is best to use hacksaw with large teeth.
                • Doped steel saws can be cured by means of a special disk on a grinder.
                • If there is a challenging job, it is better if a recessed handle will be provided in the design of the hacksaw.
