Arc Abrasives 71-31467 Quick Lok Disc Type S 3in Grit 100

Product Description

The ARC ABRASIVES 71-31467 is a Type S Quick Lok abrasive disc designed for angle grinders and other quick-change rotary tools. Measuring 3 inches in diameter with a 100-grit abrasive surface, this disc uses a mechanical locking button center that secures the disc to the tool with a simple twist. The self-sharpening grain formulation continually exposes fresh cutting edges during use, making these discs a cost-effective alternative to full ceramic abrasive materials. They are well suited for surface preparation, light stock removal, and blending work on mild steel. Each box contains 50 discs.

These discs are intended for use on mild steel in light fabrication, maintenance, and repair applications. The Type S mechanical attachment system is compatible with quick-change disc holders found on standard angle grinders and die grinders used in metal fabrication shops, welding operations, and general industrial maintenance. The 100-grit rating makes them appropriate for intermediate finishing and surface conditioning rather than aggressive material removal. Installation and disc changes require no additional tools, reducing downtime during repetitive grinding tasks.

Installation Notes

Disc changes should be performed with the grinder powered off and unplugged or air supply disconnected. Verify that the tool spindle speed rating meets or exceeds the maximum RPM marked on the disc or packaging before mounting.
