Dynabrade 51306 Straight Air Die Grinder 0.5 Hp 20000 Rpm

Product Description

The DYNABRADE 51306 is a straight air die grinder designed for precision grinding, deburring, and surface finishing in industrial and trade applications. Powered by compressed air at 90 psig, it delivers up to 20,000 RPM with a 0.5 horsepower motor and a rear exhaust configuration that directs air away from the work surface. The lever throttle gives the operator direct speed control during use. It ships with a 1/4 inch collet insert and accepts optional collet sizes to accommodate a range of tooling. At 1.8 pounds, it is lightweight enough for extended overhead or detail work.

This die grinder is suited for metalworking, fabrication, and maintenance applications in manufacturing plants, machine shops, and field service environments. It is used by machinists, pipefitters, ironworkers, and maintenance technicians for tasks such as weld cleanup, port matching, and gasket surface preparation. The rear exhaust design makes it practical in confined spaces where forward-directed exhaust would contaminate the work area or the operator's line of sight.
