Industrial-Strength Grinding for Granite & Engineered Stone

The Gison GPW-216 is built for the fabricator who demands consistent power. Featuring a high-torque 0.95 HP motor, this 7-inch wet air grinder is engineered for heavy-duty material removal, edging, and levelling on granite, marble, and quartz surfaces.

Unlike electric alternatives, the GPW-216 eliminates electrical hazards in wet work environments. Its center water feed function ensures your diamond abrasives stay cool while suppressing harmful silica dust, keeping your shop compliant with current NZ safety standards.

Why Professionals Choose the GPW-216:

• Heavy-Duty Torque: 0.95 HP (694W) motor provides the muscle needed for rapid material removal.
• Silica Dust Control: Integrated water feed directs flow exactly where the grinding happens, neutralizing airborne dust.
• No Electrical Hazards: Pneumatic design allows for safe operation in wet fabrication zones.
• Rugged Durability: Solid die-cast construction built to withstand the abrasive demands of professional stone workshops.
• Ergonomic Comfort: Plastic sleeve prevents the aluminium housing from transferring cold to the operator's hands.
