Pneumatic Die Grinder for Marine Metalworking

This pneumatic die grinder is engineered for demanding metalworking tasks in shipbuilding and repair environments. With a no-load speed of 22,000 RPM and a 3/8-inch collet capacity, it efficiently removes excess material, smooths welds, and prepares surfaces for coating. The tool operates at 90 PSI (6.3 bar) and consumes 4 CFM of air, ensuring consistent performance in continuous use.

Weighing only 0.8 kg (1.7 lbs), its compact and lightweight design allows easy access to tight spaces such as engine rooms, bilges, and superstructures. The 1/4-inch NPT air inlet connects to standard shop air lines, and the ergonomic grip reduces operator fatigue during extended grinding sessions. Ideal for marine fitters, welders, and shipyard technicians.
