How to choose a jig saw for effective work?
When deciding which to choose a jigsaw, the first step is to decide whether you need a professional or consumer tool. If the plans do not often use the device, then the household will be an excellent option. It is less powerful, but lighter, often has more additional functions and costs an order of magnitude less.
If it is planned to carry out major repairs, then the best option is a professional tool. The household jigsaw can not withstand heavy loads and do not wait until the repair is completed. Deciding which jigsaw is best, you should pay attention to the following points. First, the swing of the saw is a very convenient function, which is necessary for long and straight cuts. If only figured sawing is done, then this option is not needed.
Second, the shape of the handle. It is mushroom-shaped and in the form of a staple. On the functionality it does not affect, but the choice of a jigsaw for comfortable work needs to be done, given this point. Thirdly, the support platforms can be stamped and cast. Cast are considered more reliable and provide more accurate work at an angle. Also worth paying attention to the technical specifications:
- Engine power - for household appliances the norm is 350 watts, for professional - 600-750 watts;
- Number of strokes per minute - the best option is 2700-3000 moves / min;
- Adjustable running frequency;
- Availability of a system for the replacement of saws;
- The ability to connect the tool to a vacuum cleaner - allows you to work without dust.
Important! To date, the market provides a large range, but it is better to stop your choice on models of famous brands.
