Cordless saws are suitable for both home and professional use. Being battery operated, they can be used anywhere as long as they are charged. When selecting a cordless saw, important parameters include the weight, the number of vibrations / revolutions per minute, and the type of battery.
Continue
Weight - the lower the weight, the easier the saw will be to operate
The number of oscillations / resolutions per minute
- Oscillations - for linear saws and jigsaws, this indicates the number of oscillations per minute. A wider range of oscialltions allows the saw to be used for a wider range of material.
- Revolutions ??- for circular saws, this indicates the number of revolutions per minute. Faster saws offer greater options for working with different materials.
Variable speed control - you can set any number of oscillations / revolutions per minute. For cutting wood, lower speeds can be better, whereas faster speeds are needed for cutting metal.
Battery
- Capacity - the higher the value in mAh / Ah, the longer the battery will last on one charge
- Voltage (V) - higher voltage means more battery power
- Battery type:
- Li-Ion - the most widely used type; Li-Ion batteries are lightweight, high-capacity, and don't suffer from memory effect. They are found in more expensive models.
- NiCd - excellent current-carrying capacity; mainly used in powerful cordless screwdrivers; suffers from memory effect.
- NiMH - a compromise between Li-Ion and NiCd. They suffer less from memory effect than NiCd but have a lower capacity, whereas they are cheaper than Li-Ion batteries.
