Overview
The Bosch GWS10-450P is a corded angle grinder running off 120-volt AC power, putting out 1200 watts at a no-load speed of 11000 RPM. That combination places it firmly in the high-performance corded segment, where continuous power delivery is a priority over portability.
At 4.7 pounds, the GWS10-450P is manageable for extended use while still offering enough mass to stabilize grinding pressure. The corded design means consistent power output regardless of battery charge state, which matters for contractors doing sustained metal fabrication or surface work.
Based on specs and verified owner reviews, the 4.6-star rating across 253 reviews at $99.00 reflects good value for a brand-name 1200-watt grinder. About 50 units sell monthly, suggesting steady ongoing demand in the corded grinder market.
