Pro-source 5520003050PRO Air Angle Grinder 4 in 12000 Rpm

Product Description

The PRO-SOURCE 5520003050PRO is a pneumatic angle grinder designed for cutting, grinding, and surface preparation tasks in trade and industrial environments. Powered by compressed air, it spins a 4-inch wheel at 12,000 RPM, delivering consistent material removal across metal fabrication, pipefitting, and mechanical service work. Air consumption runs at 4 CFM at 90 psi operating pressure, with a 1/4-inch NPT inlet and rear exhaust routing to keep debris directed away from the operator. The 3/8-24 spindle accepts a standard range of abrasive wheels and accessories. At 4 pounds, the tool is manageable for extended use in tight or overhead work positions.

This angle grinder suits residential and commercial trade applications where a compressed air supply is already on site. Pipefitters, HVAC sheet metal techs, plumbers, and general mechanical contractors use pneumatic grinders for weld dressing, burr removal, and pipe end preparation. The 4-inch wheel diameter keeps the tool compact enough for confined spaces while still covering common grinding and cut-off tasks. It is well-suited for shop benches, service vehicles, and job-site use wherever a 90 psi air supply is available.

Compatibility

Designed as a direct-use pneumatic angle grinder compatible with standard 4-inch abrasive wheels and cut-off discs using a 3/8-24 spindle thread, suitable for use with any compressed air system supplying 90 psi at a minimum of 4 CFM through a 1/4-inch NPT connection.

Installation Notes

Installation and operation should be performed by qualified tradespeople familiar with pneumatic tool safety practices. Depressurize and disconnect the air supply before mounting or changing any wheel or accessory. Verify that all abrasive wheels are rated at or above the tool free speed before use, and confirm that wheel guards are properly seated. Follow applicable OSHA and ANSI B7.1 standards for abrasive wheel safety during setup and operation.
