Dynabrade 52678 Air Die Grinder 1 Hp 18000 Rpm

Product Description

The DYNABRADE 52678 is a straight-handle air die grinder built for continuous-duty material removal in industrial and trade environments. Powered by compressed air at 90 psi and 40 CFM, it delivers 1 hp and spins at 18,000 RPM, making it well suited for grinding, deburring, and finishing with carbide burrs, mounted points, rotary files, and abrasive discs. The rear exhaust directs air away from the work surface, keeping debris clear of the operator. At 15.375 inches overall length, it fits standard pneumatic tool setups and accepts a 3/8 inch inlet. CE and EAC certifications confirm compliance with applicable safety standards.

This grinder is used in metal fabrication shops, maintenance facilities, and manufacturing environments where precise material removal is required on castings, welds, and machined surfaces. The lever throttle provides variable speed control during extended operations. It ships with 1/4 inch and 6 mm collet inserts and is compatible with optional 1/8 inch, 3/8 inch, and 8 mm collet inserts for broader accessory versatility. Typical users include industrial maintenance techs, fabricators, and toolroom machinists.
