Dynabrade 52293 Angle Air Die Grinder 18000 Rpm

Product Description

The DYNABRADE 52293 is a 1/4-inch angle air die grinder designed for precision grinding, deburring, and surface finishing in metalworking, fabrication, and maintenance applications. It runs on compressed air at 90 psi and delivers up to 18,000 RPM through a lever-style throttle, giving the operator consistent speed control during extended use. Rated at 0.7 hp, the tool features rear exhaust to direct airflow away from the workpiece and the operator. The 52293 accepts 1/4-inch collet inserts as standard and ships with both a 1/4-inch (50013) and a 6 mm (50016) collet insert included.

This angle die grinder is suited for use in metal fabrication shops, aerospace maintenance, tool and die work, and general industrial environments where a right-angle grinder profile is required to reach confined areas. The lever throttle allows gradual speed ramp-up, which is particularly useful when working on delicate surfaces or in tight clearances. Licensed contractors and industrial maintenance technicians are the primary installers and users of this tool.

Installation Notes

Connect to a regulated compressed air supply set to 90 psi using a properly rated air hose and fittings. Ensure the air supply is shut off and depressurized before changing collets or accessories. Always verify the collet insert is fully seated and tightened before operating the grinder. Use appropriate PPE including eye protection and hearing protection when operating pneumatic grinding tools.
