Pro-source 5520007888PRO Pneumatic Cutoff Grinder 3 Inch

Product Description

The PRO-SOURCE 5520007888PRO is a pneumatic cutoff and grinder tool designed for metal cutting and grinding applications in fabrication, maintenance, and repair environments. Powered by compressed air, it spins a 3-inch wheel at up to 20,000 RPM, delivering fast material removal on ferrous and non-ferrous stock. The straight handle provides a direct, controlled grip suited for inline cutting operations. Air supply connects through a 1/4 NPT inlet, requiring 4.00 SCFM at 90.0 psi for consistent performance. This tool is typically installed and operated by machinists, pipefitters, millwrights, and general maintenance technicians working in shop or field settings.

This cutoff grinder is suited for straight-line cutting and surface grinding on metal pipe, sheet stock, and structural components. The compact 3-inch wheel diameter makes it practical in tight spaces where larger angle grinders cannot reach. It ships with a set of included consumable and maintenance components, making it ready for service out of the box. The straight handle configuration is standard for applications requiring direct forward pressure along the cut line.

Installation Notes

Installation and operation should be performed by qualified technicians familiar with pneumatic tool safety practices. Disconnect the air supply line before installing or changing the cutoff wheel, and verify that operating air pressure does not exceed the rated 90.0 psi at the tool inlet. Ensure the wheel is rated for a minimum of 20,000 RPM before mounting. Always wear appropriate eye, face, and hand protection during operation per ANSI and OSHA abrasive wheel safety guidelines.
