Dynabrade 51703 Straight Air Die Grinder 50000 Rpm

Product Description

The DYNABRADE 51703 is a straight air die grinder designed for precision grinding, deburring, and surface finishing in demanding trade and industrial environments. Powered by compressed air at 90 psi, the tool delivers a no-load speed of 50,000 RPM through a 1/8 inch collet, making it well-suited for detailed work in confined spaces. Output is rated at 0.1 hp with an air consumption of 8 CFM. A lever-style throttle provides smooth speed control, and the rear exhaust directs airflow away from the workpiece. The unit ships with a high-quality flexible air hose included.

The 51703 is used in metalworking, fabrication, automotive, and MRO applications where fine material removal or finishing is required. Its straight-body profile and high spindle speed make it a practical choice for technicians working on mold finishing, weld cleanup, and port work. It fits into standard shop setups running compressed air at 90 psi with adequate CFM supply from a compressor or distribution line.
