Bosch GWX13-50 5" 13-Amp X-LOCK Slide Switch Corded Angle Grinder

The Bosch GWX13-50 5-inch 13-amp corded angle grinder executes heavy structural steel sectioning, weld bead leveling, pipeline beveling, and concrete masonry scoring. Driven by a high-output 120V industrial electric motor delivering 11,500 no-load RPM with epoxy-armored field coils and directed airflow cooling, this 5.5-lb grinder incorporates the tool-free X-LOCK snap-on mounting interface to change abrasive wheels up to five times faster without spanner wrenches or loose flange nuts. Equipped with a lock-on slide switch, a Vibration Control side handle, spiral bevel power transmission gearing, a tool-free burst-resistant guard, and Service Minder brush diagnostics, it delivers optimal leverage, operator comfort, and continuous cutting performance across demanding metal fabrication shops and industrial jobsites.

Best Used For:

  • Structural Steel Sectioning and Pipe Fabrication: Cutting thick structural steel beams, carbon steel angle iron, and schedule 40/80 pipe joints cleanly with 5-inch X-LOCK abrasive wheels.
  • Heavy Weld Seam Grinding and Bead Blending: Leveling multi-pass stick, MIG, and flux-cored weld beads flush across industrial steel plates and chassis fabrications.
  • Masonry Tuckpointing and Concrete Scoring: Chasing mortar joints, dressing precast foundation edges, and scoring paving stones when paired with compatible diamond cutting shrouds.

Key Performance & Safety Features

  • X-LOCK Tool-Free Mounting System: Snap-on wheel mount clicks into place securely and ejects instantly via a mechanical pull release lever, eliminating spanner wrenches.
  • 13.0-Amp Industrial Motor: Supplies continuous corded electrical torque generating 11,500 RPM to sustain wheel velocity under heavy stock removal loads.
  • Vibration Control Auxiliary Side Handle: Ergonomic side grip incorporates an internal elastomeric isolation damper that significantly absorbs hand-arm vibration.
  • Epoxy-Armored Motor Protection: Heavy epoxy coating on field windings shields copper components against conductive metallic swarf and abrasive concrete dust.
  • Precision Spiral Bevel Transmission: Hardened helical bevel gears ensure smooth torque transfer, reduced mechanical gear chatter, and long transmission life.
  • Service Minder Carbon Brush System: Automatically disengages power when carbon brushes reach maintenance limits, preventing internal commutator damage.
