Industrial 4-Inch (100mm) Pneumatic Air Angle Grinder:
- Technical Specifications: Compatible grinding disc diameter 100 mm (4 inches), spindle thread M10 x 1.5, free speed 11,000 RPM, working air pressure 6.3 bar (90 PSI), average air consumption ~4.0 CFM (113 L/min), air inlet 1/4" NPT, lightweight aluminum alloy body with ergonomic comfort grip, rear exhaust with integrated sound-dampening muffler.
- 100% Spark-Free & Electric Shock-Proof Operation: Driven entirely by compressed air without carbon brushes or electrical coils, making it intrinsically safe in explosive chemical vapor and damp ship repair environments.
- High-Speed 11,000 RPM Continuous Grinding Power: Powers through heavy weld bead grinding, metal burr removal, rust scale stripping, and structural steel plate cutting.
- Lightweight & Anti-Fatigue Ergonomic Balance: Weighs half as much as equivalent electric angle grinders, minimizing arm fatigue during overhead and confined space ship hull work.
- Low-Vibration Rear Exhaust System: Channels exhaust air and residual oil mist rearward away from the workpiece and operator's face through an integrated silencer.
- Applications: Shipyard hull fabrication, heavy steel structure welding, pressure vessel manufacturing, foundry deburring, and automotive collision repair.
