The minimum stroke frequency of the jigsaw blade during operation. In some cases (for example, when working on metal), a low stroke rate is preferable to a high one; accordingly, the lower the minimum frequency, the more opportunities you will have to set up the instrument for working on a particular material.
- Charger. A device for charging the batteries used in the tool with the appropriate power supply. For models supplied with such a device, the charger model may be additionally specified in the characteristics. This information can be useful not only for finding a spare or replacement charger, but also in case the household has other cordless tools and / or batteries for them. On the other hand, a lot of modern cordless tools come without a charger at all. This option will be optimal, first of all, if a compatible memory is already available, and there is simply no need to overpay for a second device. In addition, the lack of a charger will be appreciated by those who want to choose this accessory separately, without relying on the manufacturer's decision.
-
Rubberized handle. The presence of a rubber pad on the handle of the jigsaw. Rubber provides a more secure hold on the tool than plastic, and also helps reduce vibration transmitted to the operator's hands. In some models, rubber pads are made corrugated - for additional reliability.
-
Protective shield. The presence in the design of the jigsaw of a transparent (usually plexiglass) protective shield in the front, near the file. It prevents fine sawdust from being scattered during operation, and also improves blowing or suction efficiency (if these functions are present, see "Functions/Features" for more details). In most cases, the p
...rotective shield is made removable.
- Case included. The presence of a special suitcase-case in the delivery set of the jigsaw. Such a case greatly facilitates storage and transportation, because. initially “sharpened” for a specific jigsaw model. In addition, additional accessories can usually be stored in it: replacement files, a tool for changing them (if required), a spare battery, etc.
- Flexible shaft. The flexible shaft is a special kind of auxiliary nozzle. Outwardly, this device looks like a hose, sometimes quite long. One end of such a "hose" is attached to the cartridge, and the other has its own cartridge, where the working nozzle is attached - rotation is transmitted to it due to the shaft located inside the "hose". The part of the flexible shaft held in the hands during operation is more compact and lighter than the jigsaw itself, so the most popular ways to use such equipment are the processing of hard-to-reach places (where the tool simply cannot crawl through) and fine work (which is difficult to do with a massive machine).
- Pedal. The presence of the pedal frees the hands of the master and allows you to adjust the speed of rotation of the nozzle by changing the pressure on the pedal. The dependence here is directly proportional - the stronger the pressure, the higher the speed.
