Dynabrade 54785 Air Angle Grinder 3 Inch 18000 Rpm

Product Description

The DYNABRADE 54785 is a pneumatic angle grinder built for demanding surface preparation, weld blending, and material removal in professional trade environments. It spins a 3-inch Type 27 grinding wheel at 18,000 RPM and draws power from a standard 90 psi compressed air supply through a 1/4-inch NPT inlet. Rated at 0.70 horsepower, the tool delivers consistent material removal in tight workspaces. A rear exhaust port directs spent air away from the work surface and the operator. The composite side handle provides a secure grip during extended use. Licensed tradespeople in fabrication, maintenance, and industrial service are the primary users of this tool.

The 54785 is suited for metalworking applications in both shop and field settings, including weld grinding, edge deburring, and surface finishing where a compact 3-inch wheel profile is required. The trigger-lock feature supports sustained operation without constant hand pressure, reducing fatigue on longer jobs. The steel right-angle housing positions the wheel at a standard working angle. An 11.4375-inch overall length keeps the tool manageable in confined access points. Air consumption runs at 41 CFM, so an appropriately sized compressor and air supply line are required to maintain consistent speed under load.

Compatibility

Designed for use with 3-inch Type 27 grinding wheels and accessories with a 3/8-24 spindle thread. Requires a compressed air supply capable of sustaining 90 psi and at least 41 CFM at the tool inlet.

Installation Notes

Install and service this tool only when the air supply is fully disconnected and depressurized. Connect the tool using a 1/4-inch NPT air fitting and verify the line can sustain the required CFM before operation. Inspect the wheel, guard, and spindle connection before each use in accordance with the wheel manufacturer's maximum RPM rating. This tool is intended for use by qualified personnel familiar with pneumatic tool safety and applicable workplace safety standards.
