Pro-source Pro-SM-5C-6414S Air Angle Grinder 4.5 in 12000 Rpm

Product Description

The PRO-SOURCE Pro-SM-5C-6414S is a pneumatic angle grinder built for grinding, cutting, and surface preparation in demanding trade environments. It accepts a 4.5-inch Type 27 wheel on a 5/8-11 spindle and runs at 12,000 RPM at 90 psi air supply pressure. Rated at 1 HP, the tool connects via a 1/4-inch NPT air inlet and routes exhaust out the rear to keep debris away from the work area. A safety lever with trigger-lock prevents unintended starts. Metalworkers, pipefitters, fabricators, and maintenance mechanics reach for this class of tool when job-site access or flammability concerns rule out electric alternatives.

This angle grinder is suited for metal fabrication shops, pipe welding operations, maintenance facilities, and construction sites where compressed air is available. The rear exhaust orientation makes it practical in tight weld joints and confined spaces where forward or side exhaust would direct debris toward the operator. The 5/8-11 spindle accepts standard Type 27 depressed-center grinding wheels and compatible accessories widely available in trade supply. It ships with a 1/4-inch Allen wrench, pin wrench, side handle, and spanner so the tool is ready to mount a wheel and put to work on arrival.

Installation Notes

Installation and wheel changes should be performed by a qualified technician familiar with pneumatic tool safety and applicable OSHA abrasive wheel standards. Always depressurize the air line and verify zero pressure at the tool before mounting or removing a wheel. Inspect the wheel for cracks or damage before every use and confirm the wheel speed rating meets or exceeds 12,000 RPM. Secure the side handle before operation and ensure all guards are in place per the tool manufacturer guidelines.
