When choosing a jigsaw, you should pay attention to power, type of handle, stroke length and maximum depth of cut. Don’t forget the other useful features. Some of them can be very useful. This article discusses three additional options that will make your work more comfortable, increase the speed and quality of your cuts, as well as help you maintain the engine carefully and extend its life.
Adjusting the number of saw strokes
This function is used to adjust the speed of the jigsaw. In most models with a power of more than 200 W, such adjustment is provided. The cheapest jigsaws only work at one speed. Cheap tools often overheat and fail quickly.
The lowest adjustment threshold is considered to be 400 blade movements per minute, the highest – 3500 movements. For sawing plastic elements, 1000 rpm is enough, for wood – 3000-3500 rpm, for metal 2700.
To set the number of strokes, use:
- a trigger that can be pressed during operation;
- electronic adjustment wheel located on the body.
If it is possible to adjust the frequency of the saw blade “up and down” and set several modes, the quality and duration of the continuous operation of the jigsaw increases.
Straight sections can be driven at the highest speed, saving time, and when maneuvering, cornering or sawing intricate ornaments, slow down and cut more carefully and quietly.
The function of maintaining a constant frequency of the stroke of the saw
This function is available for expensive professional models with constant electronics. It is missing from budget puzzles.
Automatic frequency maintenance is useful when working with heterogeneously structured materials. If there is such a function, the owner of the jigsaw will not have to keep up with the speed, monitor the intensity of pressure and control the load on the saw blade during cutting. Electronics does it for one person.
If you have to cut a lot and often with long cuts, automatically maintaining a constant speed of the saw will help reduce the load on the motor, prevent overheating and, in the long term, increase the life of the saw. ‘power tool.
Craftsmen who rarely use the jigsaw or the saw in short cycles will not be able to take advantage of the benefits of this feature.
Fixing the blade – with a key or a quick-release device
Many inexperienced users find that working with a jigsaw equipped with a quick clamp is much more pleasant and faster. To change the files, these specialists do not need a key or rod.
Experienced craftsmen are used to tightening the saw blade with a bolt and occasionally check the reliability of the saw blade by tightening the bolt with a hex wrench. Most users rarely change saw blades. They are willing to spend an extra minute unscrewing the bolt rather than paying too much for a quick tightening.
The presence of a clamping device is useful only for those who cut everything with a jigsaw: wood, boards, metal and plastic parts. If you constantly use a jigsaw, a quick-clamping device for attaching files will not hurt.
If you choose the right saw blade, the jigsaw will cope with the board, metal profile and even laminate. Do not forget to control the load on the motor, change blades and choose a tool with additional functions.
