Overview

The Cordless F3 is an 18V battery-powered grinder running at 8000 RPM, weighing 1.63 kilograms, built for cutting, grinding or surface prep away from a power outlet.

Running on battery power rather than a cord, this grinder trades outlet dependence for the weight of an onboard battery, and the 1.63 kilogram figure likely reflects that battery-equipped weight. Disc size is not listed in this entry, so confirm the wheel diameter it accepts before buying replacement discs.
