Dynabrade 53808 Straight Air Die Grinder 0.5 Hp 24000 Rpm

Product Description

The DYNABRADE 53808 is a straight air die grinder designed for precision grinding, deburring, porting, and surface finishing in industrial and trade environments. Powered by compressed air at 90 psi and rated at 0.5 horsepower, it reaches speeds up to 24,000 RPM, making it effective for work on metal, composites, and hard materials. The lever-style throttle gives operators direct speed control during use. Air consumption is rated at 29 CFM, so pairing it with an adequately sized compressor is important for consistent performance. The rear exhaust design directs airflow away from the work surface and the operator. This tool is installed and used by machinists, maintenance mechanics, fabricators, and skilled tradespeople.

The 53808 is suited for industrial maintenance, fabrication shops, automotive shops, and general metalworking applications where a compact, high-speed rotary tool is needed. The standard 1/4 inch collet insert is included. The tool also accepts optional collet inserts in 1/8 inch, 3/8 inch, 6 mm, and 8 mm sizes, allowing use with a wide range of die grinder bits, carbide burrs, and mounted points. This flexibility makes it adaptable across different grinding and finishing tasks without requiring a different tool body.

Installation Notes

Connect to a clean, dry compressed air supply regulated to 90 psi using a properly sized air line and fittings. Ensure the compressor can sustain 29 CFM to avoid pressure drop under load. Inspect the collet and collet nut before each use and confirm the accessory is fully seated and secured before operating. Always disconnect the air supply before changing collets or accessories.
