Dynabrade 53245 Air Angle Grinder 7 Inch 8500 Rpm 3 Hp

Product Description

The DYNABRADE 53245 is a heavy-duty air-powered angle grinder built for demanding material removal, weld grinding, and surface preparation in industrial and fabrication environments. It runs on compressed air and delivers 3 horsepower at a no-load speed of 8,500 RPM, driving a 7-inch grinding wheel on a 5/8-11 spindle. Air is supplied through a 1/2-inch NPT inlet, and exhaust exits at the rear to direct airflow away from the operator and workpiece. At 9.8 pounds, this tool is sized for sustained overhead and horizontal grinding by skilled trades professionals in metalworking, shipbuilding, and structural steel applications.

This angle grinder is intended for professional use in heavy industrial, manufacturing, and fabrication settings where large-diameter grinding wheels are required. It is well suited for weld dressing, deburring, and aggressive stock removal on steel and other metals. The rear exhaust configuration makes it practical in confined work areas where forward exhaust would be disruptive. Licensed tradespeople and journeymen metalworkers in industrial maintenance and fabrication shops are the primary users of this tool class.

Key Features

• 3 HP air motor delivers sustained power for heavy grinding and weld removal
• 8,500 RPM no-load speed optimized for 7-inch abrasive wheels
• 5/8-11 spindle thread accepts standard large-diameter grinding wheels and flap discs
• 1/2-inch NPT air inlet sized for high-volume compressed air supply lines
• Rear exhaust directs airflow away from the operator and work surface
• 97 CFM air consumption rating for use with appropriately sized compressor systems

Compatibility

Designed for use with standard 7-inch grinding wheels and abrasive discs with a 5/8-11 arbor thread. Requires a compressed air supply capable of sustaining 97 CFM at the tool inlet for rated performance.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with pneumatic tool safety and applicable OSHA standards for abrasive wheel machinery. Always disconnect the air supply before mounting or changing grinding wheels, and verify that the wheel's rated RPM meets or exceeds the tool speed. Use the correct wheel guard as required by ANSI B7.1 and confirm that the air supply line and fittings are rated for the required pressure and flow. Inspect the spindle and wheel flange for damage before each use.
