Dynabrade 54767 Air Angle Grinder 3 Inch 18000 Rpm

Product Description

The DYNABRADE 54767 is a pneumatic angle grinder built for grinding, blending, and finishing applications in fabrication, metalworking, and maintenance environments. It accepts a 3-inch Type 27 wheel and spins at 18,000 RPM, driven by a 0.70 HP air motor that requires 90 psi supply pressure and consumes 41 CFM at full load. The rear exhaust design routes spent air away from the work surface and the operator. A trigger-lock mechanism allows sustained operation without continuous hand pressure, reducing fatigue on long jobs. Licensed tradespeople and skilled fabricators are the primary installers and operators of this tool.

The 54767 is suited to tight-clearance grinding and weld blending in fabrication shops, structural steel work, and general industrial maintenance. The side handle and composite grip provide two-point control during aggressive material removal. At 8 inches in overall length and 2.8 pounds, the tool fits into confined areas where larger 4.5-inch or 5-inch grinders cannot reach. The adjustable wheel guard ships with the tool, making it ready for immediate use on Type 27 depressed-center wheels in production or field repair settings.

Key Features

• Composite side handle and steel right-angle housing included in the box
• Adjustable wheel guard ships standard with the tool

Compatibility

Designed for use with 3-inch Type 27 depressed-center grinding and blending wheels with a 3/8-24 spindle thread; verify wheel RPM rating meets or exceeds 18,000 RPM before mounting.

Installation Notes

Disconnect the air supply and bleed the line before mounting or changing wheels. Verify that the compressor delivers clean, dry air at 90 psi and that the supply line is rated for the 41 CFM demand. Inspect the wheel guard and ensure it is properly adjusted and secured before operating. Follow applicable OSHA 29 CFR 1910.243 standards and the wheel manufacturer's maximum RPM rating when selecting and installing abrasive wheels.
