Overview

A tradesperson who wants to cut or grind away from a wall outlet gets a battery powered angle grinder here. The listing gives voltage, speed, weight and body size, but no wheel diameter or guard details.

The reason to look at it is the cord free design with a high stated speed, which suits jobs where the outlet is far away. The limit is a thin listing: wheel diameter, included battery and charger are all unstated.

Who it's for

Cutting and grinding work in places without a nearby outlet is the situation it targets. A buyer wanting a bundled battery or a known wheel diameter should check the manufacturer first, because the listing gives neither.

Pros and cons

Pros
  • Battery powered, no cord to manage
  • Cord free for work away from outlets
  • High stated speed for cutting and grinding
  • Body size and weight both listed
Cons
  • Wheel diameter not listed
  • Battery and charger not confirmed
  • Motor power figure is unexplained

Performance notes

Wheel speed comes from the motor and the voltage of the battery platform, so the listed rotational speed tells you how quickly a wheel cuts or grinds. Output under load depends on the battery pack used, which the listing does not specify. The low listed weight reduces fatigue on long passes.
