Dynabrade 52258 Straight Air Die Grinder 0.7 Hp

Product Description

The DYNABRADE 52258 is a straight air die grinder designed for precision grinding, deburring, and surface finishing in industrial and trade environments. Powered by compressed air at 90 psig, it delivers 0.7 horsepower and a rated speed of 20,000 RPM, with an operating range of 18,000 to 24,999 RPM. The lever throttle gives the operator consistent control over speed and material removal. Front exhaust directs air away from the workpiece, keeping the work area cleaner during operation. The 52258 accepts a standard 1/4 inch collet insert and is compatible with several optional collet sizes. It is used by machinists, pipefitters, fabricators, and maintenance technicians in shops and field environments.

This grinder is suited for light to medium grinding and finishing tasks in automotive, metal fabrication, HVAC fabrication, and general industrial maintenance settings. The straight inline body makes it practical for accessing confined workspaces where right-angle tools cannot reach. The lever throttle allows for variable speed modulation without requiring a separate regulator adjustment. Weighing 2 pounds, it reduces operator fatigue during extended use. The included 1/4 inch collet insert covers the most common rotary file and mounted point sizes used in trade work.
