Overview
Metabo's G12SR4 spins at a fixed 12,000 RPM on corded 120 volt power, weighing 4 pounds in a slim 10.15 by 4.5 by 2 inch body built for one-handed grinding and cutting.
This model carries the Metabo HPT lineage, formerly sold under the Hitachi name, a line known for compact 4.5 inch angle grinders. Amperage is not listed in the spec data here, so motor draw is unconfirmed beyond the 12,000 RPM speed rating.

Who it's for
