Dynabrade 53812 Straight Air Die Grinder 0.7 Hp

Product Description

The DYNABRADE 53812 is a straight air die grinder built for precision material removal, deburring, porting, and surface finishing in production and maintenance environments. Powered by compressed air at 90 psi, it delivers 0.7 horsepower and spins at up to 20,000 RPM, giving technicians the speed needed to cut, grind, and blend efficiently. Air consumption is rated at 38 CFM. The rear exhaust design directs spent air away from the work surface and operator. A lever-style throttle provides responsive speed control throughout the cut. The 53812 ships with a 1/4 inch collet insert and accepts optional collets in multiple sizes to broaden its range of compatible tooling.

The 53812 is suited for metal fabrication shops, automotive service, aerospace maintenance, and general industrial applications where a compact, straight-body grinder is required. It handles carbide burrs, mounted points, and abrasive mandrels commonly used for weld cleanup, port work, and die finishing. The lever throttle and inline body make it a practical choice for work in tight cavities or along contoured surfaces. Installation of tooling and daily operation are typical tasks for machinists, tool-and-die workers, and industrial maintenance technicians.

Installation Notes

Installation and daily operation of air die grinders is typically performed by machinists, fabricators, or industrial maintenance technicians. Before mounting or changing tooling, disconnect the air supply and verify the line is depressurized. Ensure the air supply is clean, dry, and regulated to the rated operating pressure before connecting the tool. Always confirm collet tightness and inspect tooling for cracks or damage before each use in accordance with applicable ANSI and OSHA abrasive tool safety standards.
