Bosch® 1812PSD is a AC/DC capable 6" angle grinder with a non-locking paddle switch that is designed to outlast the competition - lasts up to 5 times longer than the current market leader. The AC/DC capability extends the versatility of this grinder by working from DC outlets such as on welders and generators. It outlasts the competition by using epoxy coated field windings, sealed switch, directed air flow and Service Minder™ brushes. The 5/8"-11 lockable spindle offers flexiblity and quick wheel changes. The tool-free adjustable guard puts the guard in just the right location without fumbling with a screwdriver and the two-position vibration control handle reduces vibration up to 60%.
