Dynabrade 53244 Air Angle Grinder 7 Inch 7200 Rpm

Product Description

The DYNABRADE 53244 is a heavy-duty air-powered angle grinder designed for demanding material removal, grinding, and surface preparation in industrial and fabrication environments. It drives a 7-inch grinding wheel at 7,200 RPM using a 3 HP pneumatic motor, delivering consistent cutting power across steel, weld seams, and hard materials. Air supply connects through a 1/2-inch NPT inlet, with a 5/8-11 spindle thread for standard wheel mounting compatibility. At 9.8 pounds, it is built for sustained use by metal fabricators, pipefitters, and maintenance technicians working in production or field settings.

This grinder is suited for heavy-duty industrial grinding applications including weld removal, bevel preparation, and stock removal on ferrous and non-ferrous metals. It performs in fabrication shops, shipyards, pipeline yards, and heavy manufacturing facilities where consistent wheel speed and high air volume are required. The rear exhaust design directs spent air away from the work surface and the operator, reducing debris interference during operation. A stable air supply delivering the rated 98 CFM is required for optimal performance at full load.

Compatibility

Designed as an OEM-style pneumatic angle grinder accepting standard 7-inch grinding wheels and discs with a 5/8-11 spindle thread mount.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with pneumatic tool safety and applicable OSHA standards for abrasive wheel machinery. Before mounting or changing wheels, disconnect the air supply line completely and verify zero pressure at the tool. Ensure the compressed air system can sustain 98 CFM at the required operating pressure before use. Always inspect grinding wheels for cracks or damage and confirm the wheel speed rating meets or exceeds the tool free speed before mounting.
