Pro-source PRO-SM-52-5201 Air Die Grinder 1 Hp 1/4 in

Product Description

The PRO-SOURCE PRO-SM-52-5201 is a pneumatic angle die grinder built for continuous-duty material removal, porting, deburring, and surface finishing in shop and field environments. Powered by 90 psi compressed air, it delivers 1 horsepower and a fixed speed of 12,000 RPM through a 1/4 inch collet. The lever throttle gives the operator direct control over tool engagement, and the angle handle style positions the grinding bit inline with the workpiece for confined-space access. Technicians in HVAC, plumbing, welding, and general maintenance trades reach for this class of tool when cutting, shaping, or finishing metal in tight quarters where a straight grinder will not fit.

This die grinder is suited for light to medium fabrication tasks in residential and commercial mechanical rooms, sheet metal shops, and field service vehicles. The 1/4 inch collet accepts standard die grinder bits, carbide burrs, mounted points, and small abrasive wheels. A 1/8 inch collet is available separately for smaller tooling. The 1/4 inch air inlet connects directly to standard shop-air quick-connect fittings at a regulated supply pressure of 90 psi. At 2.6 pounds, the tool stays manageable during extended overhead or lateral grinding passes.

Installation Notes

Connect the 1/4 inch inlet to a regulated compressed-air supply set to 90 psi before operation. Verify the collet nut is fully tightened and the bit shank is fully seated before spinning the tool. Always wear eye protection and appropriate PPE when operating pneumatic grinders. Disconnect air supply before changing collets or tooling.
