Dynabrade 52276 Straight Air Die Grinder 0.7 Hp 15000 Rpm

Product Description

The DYNABRADE 52276 is a straight air die grinder designed for precision material removal, grinding, deburring, and surface finishing in demanding trade and industrial applications. Powered by compressed air at 90 psig, it delivers 0.7 horsepower and operates at up to 15,000 RPM. The lever-style throttle gives the operator direct speed control during use. Rear exhaust directs airflow away from the work surface, keeping the work area cleaner and reducing debris interference. This grinder ships with a 1/4 inch collet insert and accepts optional collets in 1/8 inch, 3/8 inch, 6 mm, and 8 mm sizes, making it adaptable across a wide range of tooling.

The 52276 is suited for metal fabrication shops, automotive repair facilities, HVAC ductwork finishing, and general mechanical trade work where a compact straight-body grinder is required. Its lightweight build at 2.3 pounds reduces fatigue during extended use. The lever throttle allows for precise starts and stops, which is important in close-tolerance deburring or die work. Machinists, pipefitters, sheet metal workers, and general maintenance technicians are the typical end users for this tool class.
