Air Grinder for Stone & Diamond Cup Wheel & Saw Blade

Our Air Grinder for Stone is engineered for high‑performance material removal and surface finishing on granite, marble, quartz, and engineered stone. Featuring a 1.2 hp (900 W) pneumatic motor that delivers up to 25,000 rpm under load, it powers through tough substrates with minimal vibration. An ergonomic, lightweight aluminum housing and rubberized grip reduce operator fatigue during extended use. The tool’s precision-balanced rotor assembly ensures smooth operation and long bearing life. A quick‑change collet system accepts 5 mm, 6 mm, and 8 mm shank burrs, allowing rapid tool swaps without additional wrenches. Integrated mufflers and an optimized air‑flow path cut noise levels to below 85 dB(A), protecting hearing while meeting OSHA standards. The air inlet features a universal swivel fitting and a built‑in moisture separator to safeguard internal components and maintain consistent performance.

What sets our Air Grinder apart is its rugged durability and maintenance-friendly design. Critical internal parts—valve seats, pistons, and cylinders—are hard‑chromed to resist wear from abrasive stone dust. Compared to electric grinders, our pneumatic unit is intrinsically safe in damp or explosive‑dust environments and delivers consistent torque without power‑cord constraints. The spindle uses double‑shielded bearings rated for 500 hours of operation before service. A precision regulator with a quick‑adjust throttle lever allows fine speed control for delicate polishing or aggressive stock removal. Backed by a 2‑year warranty and a global spare‑parts network, this air grinder minimizes downtime and total cost of ownership for stone fabricators and tile installers alike.
