Dynabrade 51300 Straight Air Die Grinder 0.5 Hp

Product Description

The DYNABRADE 51300 is a straight air die grinder designed for precision grinding, deburring, and surface blending in demanding trade and industrial applications. Powered by compressed air at 90 psig operating pressure, it delivers up to 0.5 HP and runs at 15,000 RPM with a speed range spanning 10,000 to 17,999 RPM. The lever-style throttle gives operators smooth speed control during extended use. A front exhaust configuration directs air away from the workpiece and the operator, helping maintain a cleaner work area. This grinder is built for use by machinists, fabricators, and maintenance technicians who require a reliable, compact straight-body air tool.

The 51300 fits a wide range of die grinding tasks in metal fabrication shops, maintenance and repair operations, and industrial production environments. It accepts a standard 1/4 inch collet insert (included as part 50013) and is compatible with optional collet inserts for 1/8 inch (50065), 3/8 inch (50014), 6 mm (50016), and 8 mm (50039) tooling, making it adaptable to a variety of grinding bits, mounted points, and rotary files commonly used in trade settings.

Installation Notes

This tool is installed and serviced by qualified pneumatic tool technicians or maintenance personnel. Before changing collets or accessories, disconnect the air supply line completely and verify pressure has bled from the tool. Ensure the compressed air supply is clean, dry, and regulated to 90 psig at the tool inlet; excess pressure can shorten tool life and poses a safety risk. Follow applicable OSHA and facility safety requirements for abrasive wheel and rotary tool use, including proper guarding and PPE.
