Dynabrade 54387 Angle Air Die Grinder 18000 Rpm 0.7 Hp

Product Description

The DYNABRADE 54387 is a 1/4 inch angle air die grinder built for precision grinding, deburring, and surface finishing in industrial and trade environments. Powered by compressed air at 90 psig, it delivers a maximum speed of 18,000 RPM and 0.7 horsepower, giving the operator consistent material removal on metal, composite, and weld surfaces. The rear exhaust design directs airflow away from the work area and the operator. A lever-style throttle provides controlled speed management during extended use. This tool is typically installed and operated by machinists, pipefitters, fabricators, and maintenance technicians working in production or job-site settings.

The 54387 is suited for angle grinding applications in tight or confined areas where a straight die grinder cannot reach. The 1/4 inch collet accepts standard die grinder bits, carbide burrs, mounted points, and cut-off wheels commonly used in metal fabrication, weld finishing, and pipe prep work. A 6 mm collet insert is included, expanding compatibility with metric tooling. At 2.8 pounds, the tool is lightweight enough for extended overhead or vertical use without significant operator fatigue. The rear exhaust keeps chips and debris clear of the grinding zone, which is useful in close-tolerance work.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with pneumatic tooling and applicable workplace safety regulations. Before connecting to an air supply, verify the supply pressure does not exceed 90 psig and that the air line is fitted with a properly rated regulator, filter, and lubricator. Always disconnect the air supply before changing collets or accessories. Inspect the collet and collet nut for wear before each use and ensure accessories are rated for the maximum RPM of this tool.
