Dynabrade Products 52632 Angle Grinder Type 27 4 1/2 in 12,000 RPM 1.3 hp

Industrial Angle Grinder for Heavy-Duty Metalwork

The Dynabrade 52632 is a Type 27 angle grinder built for demanding metal fabrication and automotive tasks. Its 1.3 hp motor delivers 12,000 RPM free speed to a 4 1/2 inch wheel for aggressive material removal. The cast aluminum housing with rubber grip withstands daily shop abuse. It suits professionals who need reliable pneumatic power for grinding and surface preparation.

Air Consumption and Exhaust Management

At 90 psi operating pressure the tool draws 43.0 CFM under full load and averages 10.75 CFM over a 15 second run cycle. A 3/8 inch NPT female air inlet and minimum 3/8 inch hose size maintain adequate flow. Rotational exhaust directs air away from the workpiece and operator. The lever throttle with safety lock prevents accidental start-up during hose connection.

Upgrade from Lower-Capacity Pneumatic Grinders

This model replaces smaller grinders that stall on weld removal or heavy deburring. The 1.3 hp output and vibration-dampening side handle reduce operator fatigue during extended sessions. The jump is worth it when free speed of 12,000 RPM and Type 27 wheel compatibility are required for the job. Buyers needing variable speed control or electric operation should consider other tool types.
