Dynabrade 51701 Air Die Grinder 0.1 Hp 60000 Rpm

Product Description

The DYNABRADE 51701 is a straight-handle air die grinder designed for precision grinding, deburring, and finishing work in industrial and fabrication environments. Powered by compressed air at 90 psi and 8 CFM, it delivers 60000 RPM through a 3 mm collet for consistent material removal on ferrous and non-ferrous workpieces. The rear exhaust directs airflow away from the work surface, keeping the work area clear of debris and coolant. At 5.25 inches in overall length and 1 pound, it is compact and light enough for extended single-hand use. Licensed machinists, toolmakers, welding fabricators, and MRO technicians are the primary installers and operators of this tool.

The DYNABRADE 51701 fits into applications where a low-profile, high-speed rotary tool is required in tight clearances. Typical uses include weld preparation, flash removal, port work, and surface blending on castings or structural components. The straight handle design suits inline access to bores, channels, and recessed surfaces where angled tools cannot reach. This grinder is suited for both production floor use and maintenance shop applications where consistent pneumatic supply is available.

Key Features

• 60000 RPM free speed for aggressive stock removal and fine finishing
• Straight handle provides inline access to tight or recessed work areas
• Rear exhaust routes air away from the operator and workpiece
• 3 mm collet accepts standard die grinder bits and carbide burrs
• Operates at 90 psi with 8 CFM air consumption
• Compact 5.25-inch length and 1-pound weight reduce operator fatigue

Compatibility

Designed for use with standard 3 mm shank rotary burrs, mounted points, and abrasive bits compatible with pneumatic die grinders rated at 60000 RPM or higher. Requires a compressed air supply capable of sustaining 90 psi at 8 CFM with a 1/4-inch inlet connection.

Installation Notes

Connection is made at the 1/4-inch air inlet using a standard quick-connect fitting or threaded NPT coupler. Verify that the compressor and air line can deliver the required 90 psi and 8 CFM before operation. Always ensure the collet is fully tightened and the accessory shank is properly seated before starting airflow. Disconnect the air supply before changing accessories or performing any maintenance.
