The Bosch GWS10-45P 4-1/2-In. Angle Grinder with Paddle Switch provides a multi-grip paddle switch for user control and comfort. It also delivers more power than previous-generation models - 10 amps and 11,500 rpm. It has directed air flow that diverts dust away from vital components, and it has direct-motor cooling, giving it higher overload capabilities. For operator comfort and control, it sports a two-position Vibration Control side handle, making it less jarring to run. It was designed for all-day jobs in machinery manufacturing, metal fabrication and construction. It has a burst-protection quick toolless adjustable guard and a large spindle lock for more convenient disc change. The Service Minder brushes stop the grinder when preventative maintenance is required.
