Corded Ryobi models are also available, and both types have been praised by users for the overall excellent match of grinder to disc tip and overall size.

Each model of grinder against which I measured the discs is designed to cut and work best with two to three specific whole disc sizes, from 100 mm to the larger 230 mm. A size of disc beyond the upper end of the range the grinder could safely handle meant cutting and grinding while removing the guard to do so, as well as having the potential of the disc spinning at two different speeds.
