Jigsaws: types
As already mentioned, this tool is used for cutting completely different materials, whether wood, plastic, metal, laminate, ceramics, plasterboard, etc. In addition, it is able to drill holes of various diameters.
The electric jaws themselves are of two kinds: household and professional .The first has a smaller working capacity, capacity and number of modes, it is produced most often in Poland and China. Usually it is excellent for wooden parts having a thickness of up to 70 mm, and steel with a thickness of up to 2-4 mm.
Professional jigsaw is applicable for much more materials. It can cut aluminum up to 20 mm thick, steel up to 10 mm, wood 80-135 mm and so on. Therefore, this instrument requires higher demands on load and productivity( it must have high power, various functions, etc.).
Jigsaw: how to choose?
Two types of tools have completely different characteristics. So, what are the parameters to pay attention to, and how to choose a jigsaw?
First, look at the power of the .It influences the continuity of work and the depth of the cut. Professional devices usually have a power of 580-750 watts, and typical households - from 350 watts. Secondly, estimate the total number of strokes per minute .This parameter is reflected in the cutting frequency and speed. Usually it is equal to 2700-3100 rpm, but there are also models with an indicator up to 3500 rpm. Third, learn about the possibility of adjusting the frequency of the .It is needed if you are going to work with several materials at once. But if you work with only one material, this function will not be useful.
Fourthly, the system for connecting to the vacuum cleaner is convenient. If there is one, then you can always keep in a clean and order not only the workplace, but also the device itself. In addition, eliminates small dust, which is so harmful to human health.

Some recommendations for using the
Like any other tool, this unit has its own recommendations for use. First, it is worth considering with what material you will work. If it is polystyrene, organic glass, stainless steel, then it is worthwhile producing some cooling. The composition for this may be the following: a soap solution, water or machine oil. Read the instructions carefully before using the unit.
It is worthwhile to monitor the condition of the file - how much it blunted. And it is important to change it in time, so as not to overload the engine. Carrying out work with a low running frequency, you need to take breaks( for the timely cooling of the engine).Finally, when processing a sheet, it's best to use a machine with high speed and power, and when cutting plastic - with a speed of 1000 rpm.
