Cordless Saws

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.
