Carrying out repairs in an apartment or a country house can be greatly facilitated if you buy a jigsaw. Well, how can I not remember the lessons of work at school, when the complex involutes from plywood were carefully sawed with a jig saw. Therefore, the appearance of the electric jigsaw made a sensation in the minds and hearts of real masters. How to choose this famous tool?

For what works is used an electric jigsaw
The electric jigsaw is a hand tool with an electric drive, which allows performing unidirectional or figured cutting of various materials.
Work with an electric jigsaw allows you to perform operations that occur in carpentry or repair areas. Therefore, the electric jigsaw is preferable to apply for work at home or in a country house. It is carving on the material and sawing wood, plastic, ceramic tiles, plasterboard, thin sheet metal and other operations that do not require the use of a powerful electric saw.
When laying the laminate, installing gypsum board elements, the electric jigsaw will be a reliable and convenient assistant. It remains to decide the question: how to choose the right tool, what jigsaw to buy.
What is the design of the jigsaw?
The construction of the jigsaw
The electric jigsaw is a tool consisting of the following parts:
• housing with internal motor
• the reference plane
• the manual holder
• saw blades
• Support roller
• Start buttons.
Any electric jigsaw, the price of which depends on the power of the electric motor, is equipped with a special saw blade that performs amplitude actions perpendicular to the plane of the material being processed. The device jigsaw allows you to set the desired working angle of cutting and keep it in the specified position.
The main driving force of the system is an electric motor, with a power of up to 900 watts. The holder of the jigsaw allows to hold the working tool - the saw in the set position throughout the whole work cycle.
The working body of the instrument is the nail file, reaching a length of up to 120 mm.
The thickness and configuration of the cut, carried out by the nail file during intensive work, reaches a size of 1 mm. With the loss of the workability of the nail file, it is possible to replace the blade for the jigsaw. The most common are saw blades intended for sawing a tree. The special configuration of the saw teeth and the frequency of the arrangement allows the sawing of soft and hardwoods.
How to choose a jigsaw for household use
There are professional and household models of electric jigsaws.
When choosing a tool for domestic use, it is necessary to take into account the technical characteristics:
• power of the tool motor
• allowable thickness of material cutting
• running speed
• availability of additional functions.
The fundamental criterion for choosing a tool can be confidently called the power of the electric motor. According to the permissible thickness of the material and power cutting, one can draw an opinion on the potential of any model of the electric jigsaw. The power of the tool can vary between 300-800 watts. The more powerful the jigsaw, the faster it is able to cut the material with a certain thickness.
Important is the characteristic - this is the depth of the cut. If you pay attention to the technical characteristics of the cutting tool, you can see that the values of the cut in the tree and in the steel are indicated. Therefore, decide for which work you can use the tool.
Guided by such data and comparing with brand models, you can make the necessary choice. In addition to the basic functions of electric jigsaws, there is an increased interest in the presence of additional tool options.
What about the additional tool functions?
Additional options are a successful set of design solutions that maximize comfortable and quick work. Recall that additional functions, which are recommended to pay attention when choosing, are:
• the presence of a pendulum mechanism
• possibility of adjusting the tool stroke parameters
• additional illumination of the working surface
• system of operative replacement of saws.
The presence of a pendulum stroke and the possibility of its adjustment can be called an important parameter when choosing a tool.
The presence of a pendulum mechanism, in which, in addition to reciprocating movements with respect to the vertical axis, horizontal movement is also reported, is an indicator of the productivity of the cutting tool. The presence of a pendulum mechanism makes the tool more productive. For example, the Makita 4329 has a three-stage pendulum and a straight stroke, which provide the maximum depth of cut for wood - 65 mm, and for steel - 6 mm. with a maximum stroke length of 18 mm. These values exceed the cutting process similar to models that do not have a pendulum mechanism.
In addition, the adjustment of the pendulum stroke will allow you to work with different materials: for soft and flexible materials, the stroke adjustment is selected as the maximum, and for the processing of rigid materials, the adjustment function can be switched off completely.
However, the pendulum regime worsens the quality of the cutting operation somewhat. For a finishing cut and high-quality processing of the surface of solid wood species, such a mechanism does not work.
The presence of a function for adjusting the travel frequency allows you to select the optimum operating mode. To do this, just set the regulator to a certain mode.
The source of power for the jigsaw can serve as an electrical outlet or battery.
For more comfortable work as additional functions, the illumination of the working area, the possibility of connecting the instrument to a vacuum cleaner or automatic blowing of sawdust are used.
Pay attention to the presence of an automatic system for swapping and turning the saws, as well as the fixation of the working angle of tilt.
For more expensive models of professional electric jigsaws, reviews of which are on the official sites of manufacturers, are characterized by built-in protection systems. Such protective means in the form of vibration silencers and the sound of a working tool make it possible to make cutting work more calm and comfortable.
