Bosch GWS22-180J 7 Inch 15 Amp Corded Large Angle Grinder
The Bosch GWS22-180J 7-Inch 15-Amp Large Angle Grinder serves as a heavy-duty metal cutting and surface preparation power tool engineered to slice carbon steel beams, grind multi-pass weld joints, and bevel iron pipes. Powered by a high-output 15.0-amp motor producing 8,500 no-load RPM, this corded 7-inch angle grinder features a 5/8-11 UNC spindle arbor, a continuous lock-on trigger switch, and a net tool weight of 9.7 pounds. Equipped with a soft-start torque system, restart interlock protection, and a Vibration Control auxiliary side handle, this 120V grinder includes dedicated protective guards for both metal cutting and surface grinding applications across pipe fitting and structural steel fabrication.
Best Used For:
- Structural Steel & Pipe Slicing: Cutting through thick carbon steel beams, iron channels, structural plates, and beveling heavy-wall industrial pipe ends.
- Multi-Pass Weld Joint Grinding: Flushing down multi-pass weld seams, removing slag, and prepping joint edges for certified structural welding.
- Continuous Metal Surface Prep & Scale Removal: Stripping deep rust, mill scale, epoxy coatings, and corrosion across wide steel plates using the lock-on trigger switch.
Key Performance & Safety Features
- High-Torque 15.0 Amp Motor: Industrial electric motor generates 8,500 RPM to sustain rapid stock removal rates and maintain wheel speed under structural load.
- Continuous Lock-On Trigger Switch: Lock-on feature keeps the motor engaged continuously during long grinding passes, reducing operator hand strain and grip fatigue.
- Vibration Control Auxiliary Side Handle: Shock-absorbing side handle dampens mechanical vibration to enhance tracking control and user comfort over long shifts.
- Smooth Torque Soft-Start Control: Limits initial power surges at startup to eliminate aggressive torque twists when engaging the motor.
- Smart Restart Interlock Protection: Prevents automatic motor reactivation following jobsite power supply disconnections or generator breaker trips.
- Dual-Guard Utility Package: Includes Type A closed cutting guard and Type B open grinding guard for immediate jobsite compliance.

Pro-Tip: Always verify that you have mounted the correct guard before starting work: use the Type A closed guard for abrasive cut-off operations and the Type B open guard for surface grinding wheels. Matching the guard to the wheel type prevents dangerous abrasive fragments from flying toward the operator in the event of wheel breakage.
