The Bosch GWS13-50P is a compact, high-output 5-inch angle grinder designed for fast cutting and grinding in metal fabrication, construction, and maintenance work. Its 13-amp motor delivers up to 11,500 RPM to keep productivity high on tough materials like steel, rebar, and castings. A no-lock-on paddle switch supports natural grip changes and quick shutoff, while Bosch constant electronics help maintain speed under load for smoother, more consistent cuts. The tool body manages heat and debris with direct-motor cooling and directed air flow that pushes dust away from internal components, helping extend service life on busy jobsites.
For control and comfort, the grinder includes a two-position Vibration Control side handle and a low-profile gear housing that fits into tighter spaces. Safety features include restart protection, an integrated acceleration sensor that helps limit inadvertent recoil, and a toolless, burst-protection guard you can adjust quickly for cut-off or grinding positions. A large spindle lock speeds wheel changes, and Service Minder brushes signal when maintenance is due. At just 5.3 lb and 12.3″ long, this corded grinder balances power, size, and durability for everyday professional use.
