Dynabrade 53280 Air Angle Grinder 7 Inch 8500 Rpm

Product Description

The DYNABRADE 53280 is a pneumatic angle grinder designed for heavy-duty grinding, blending, and surface preparation in industrial and fabrication environments. It accepts a 7-inch Type 27 grinding wheel and operates at 8,500 RPM, delivering consistent material removal on steel, weld seams, and other hard surfaces. Air consumption runs at 115 CFM, and the grinder connects via a 1/2-inch air inlet. The adjustable exhaust allows the operator to direct airflow away from the work surface or the user. At 7.3 pounds and 13.4 inches in overall length, it is sized for sustained use by metalworkers, fabricators, and maintenance trades.

This grinder is suited for industrial fabrication shops, metal service centers, shipyards, and heavy maintenance facilities where large-diameter wheel work is routine. Its Type 27 wheel compatibility makes it appropriate for weld blending, surface conditioning, and stock removal on structural steel and plate. The pneumatic drive requires a compressed-air supply capable of sustaining adequate volume at operating pressure. Installation and operation are handled by experienced metalworking tradespeople or industrial maintenance personnel.

Installation Notes

Installation and wheel changes must be performed by qualified personnel following ANSI B11 and OSHA 29 CFR 1910.215 abrasive wheel machinery standards. Disconnect the air supply and verify zero pressure before mounting or removing any wheel. Always inspect the wheel for cracks or damage before installation, and confirm the wheel speed rating meets or exceeds the tool RPM. Use the appropriate wheel guard and personal protective equipment during operation.
