Overview
The Bosch GWS10-450P is a corded angle grinder with a 1200 watt motor spinning at 11000 RPM, weighing 4.7 pounds.
Bosch is an established name in corded power tools, and the combination of a 1200 watt motor and 11000 RPM spindle speed is typical of an angle grinder built for metal cutting, grinding, and surface prep. At under 5 pounds it sits on the lighter end for a corded grinder, which usually helps with control during extended use.
