Features of reciprocating saws for metal

In the construction and household spheres, it is often necessary to use a tool such as a saw. Most often, hacksaws are used to dismantle any structures or cut parts for the subsequent installation of structures. One of the most effective tools in the work is this type of tool as a reciprocating saw, designed for cutting metal. In order to correctly choose and correctly use a building unit, one should understand the types of modern products, the features of the device of the product and the rules for its use.

A metal reciprocating saw can be thought of as a hybrid of a jigsaw and a chain saw. With the latter type, the device is brought together by the autonomy of the working body, the characteristic advantage of which in comparison with a jigsaw and a circular saw is the ability to work without support on a flat surface. And the similarity with the electric hawk is confirmed by the fact that the cutting blade of the saber device moves along a reciprocating trajectory.

The main advantage of such a saw is its design, which allows you to work in hard-to-reach places.where circular saws simply do not fit. And also such a tool does not dull if in the process of carving any obstacle, for example, a nail, is touched. The cut of a reciprocating saw for metal is very accurate and clean, for which many builders and locksmiths choose it for work.

The reciprocating hacksaw can only make one type of cut: straight. To carry out curly cutting, it is necessary to purchase special thin canvases for this. Sheets for such carving are curved and bendable. And also the devices have a small blade length: in the range from 100 to 350 mm.

A reciprocating saw of this type is used mainly for cutting durable metal, which includes structures such as steel profiles, various pipes, fittings and non-ferrous metal products. Since a wide range of different blades can be found for this tool, the range of materials for which it is used is also very wide:

• stainless steel;
• aluminum;
• red-hot metal.

The purpose of the saw can be classified according to the type of work.

• Cutting metal by weight. It is the reciprocating saw that is convenient, since its design minimizes the load on the hands, unlike other types of devices.
• Before collecting any structures, it may be necessary to cut the metal parts.
• The tool is used to create curved cuts.
• For the safety of operation, the aesthetic appearance of structures and other purposes, the ends of the parts are rounded with the help of a saber electric saw.
• Repair work, during which it is necessary to dismantle metal structures, for example, radiators.

An electric hacksaw for metal can be of several varieties. The first feature underlying the classification of instruments is their power. According to this parameter, 3 types of reciprocating saws are distinguished.

• With motor from 400 to 600 watts. Such a unit is most often used for simple locksmithing work.
• A higher indicator - from 700 to 1000 watts - is typical for a tool used for a wider range of domestic purposes.
• If the electric saw motor has a power of 1200 watts, then this tool is able to cut the most durable metal materials. Moreover, it is characterized by a long service life.

Electric reciprocating saws for metal also differ in the number of blades. In most models, it is presented in a single copy, but there are variations with two blades with an oncoming trajectory. For certain types of work, mini-units are used that have little power. The stroke rate of such a device is usually adjustable. This option is especially useful for working in confined spaces.

Unlike hand-held hacksaws, the saber device can be battery-powered and pneumatic... The battery device has a removable part: the battery, which must be charged periodically by connecting to the mains. Depending on the capacity of the battery, there is enough charge for different times of use. Another type of device is pneumatic saws that work through an air compressor. Battery-free devices are connected directly to the mains using a cord. The disadvantage of these types of electric saws is the possibility of their use only in rooms equipped with electricity. Cordless devices can work without being connected to the mains.

In order not to be mistaken when choosing an electric saw for cutting metal, a number of nuances and characteristics of such devices should be taken into account.

• The decisive criterion is the power of the device. It is determined depending on the type of planned work.
• If you plan to cut various types of materials, choose a device with a keyless blade change function.
• Pay attention to how the depth of cut is adjusted in the electric file, and whether the device has such an option. This process can be done with or without a key. The latter option is more convenient. If there is no such function in a reciprocating saw, then its blades will last less long.

• Some tool models have a proprietary blade that allows you to use only one type of blade. And some are more versatile.
• An important criterion for choosing a reciprocating saw for metal is the ergonomics of this device. It must have features such as 180 ° pivoting, vibration-absorbing rubber pads and an adjustable guide shoe, and must be equipped with a counterweight.
• More accurate work is ensured by saws in which there is a function to turn off the pendulum movement of the blades.

Experienced craftsmen believe that working with such a unit as a saber electric saw is not difficult, and everyone can learn it. However, there are a number of recommendations that allow you to master this skill with minimal negative consequences.

• Before cutting the main parts, be sure to try the operation of the equipment on a rough surface. These may be unnecessary pieces of metal. This procedure will help not only check the tool for quality and the presence of defects, but also help a novice user to fill his hand and get used to the electric hawk.
• One of the preparatory work will also be the adjustment of the support shoe. It is recommended that the length of the head extending beyond the blade is kept to a minimum.
• And also when working, you need to clearly follow a simple algorithm of actions. To start cutting for metal, you first need to press the start button in a smooth motion and bring the saw to the area where the cutting will be carried out.

• After that, it will only be necessary to correctly direct the unit, the blade of which will independently plunge into the metal.
• Blind cuts are not recommended. This can lead to damage to the gear units.
• Be careful when cutting metal, sometimes the tooling may begin to bend. A peculiarity when working with metal parts is that this process usually takes place not at the beginning of work, but closer to the middle of it.
• When working with blades that show signs of deformation, the risk of tool wear increases. Therefore, it is recommended to choose a metal with a minimum number of defects.
• As a regular maintenance procedure, the instrument should be lubricated and cleaned.

In the market of construction and repair equipment, a number of companies are leading, which have in their assortment saber plates for metal products.

• Bosh offers customers electric saws with D-shaped handles and rubberized areas for improved hand grip. The system of these devices is endowed with a mechanism for smooth speed control.

• The company offering the most budgetary products is Elitech... A significant plus will be the low price of consumables for the tool. The saw weight does not exceed 2 kg. However, when working with metal products, you need to proceed with caution, since such devices have mostly low power.
• Among the reciprocating saws with a powerful motor are presented Makita tools... They are often equipped with a vibration-reducing system. Perfect for metal products, creating a cut with a depth of 13 cm. The device switch has four positions and is very convenient to adjust. The high price of the products is justified by the available advantages.
