Arc Abrasives 71-31456 Quick Lok Disc Type S 2in Grit 120

Product Description

The ARC ABRASIVES 71-31456 is a 2-inch Quick Lok abrasive disc with a Type S mechanical locking center, designed for use with Quick Lok-compatible angle grinders and die grinders. The Type S button center locks the disc onto the tool with a simple twist, providing secure, repeatable positioning during operation. At grit 120, this disc delivers fine-to-medium material removal suitable for surface conditioning, blending, and deburring on mild steel. Sold in boxes of 100, it is a cost-effective solution for shops and field technicians who require consistent abrasive performance without the price premium of full ceramic disc construction. The self-sharpening grain structure extends usable disc life across repeated passes.

This disc is intended for use on mild steel in light fabrication, maintenance, and repair applications. The 2-inch diameter fits compact grinder heads and right-angle die grinders commonly used in tight-access areas on structural steel, ductwork, pipe ends, and sheet metal assemblies. The grit 120 rating makes it well suited for finishing passes after heavier stock removal, leaving a consistent surface profile. It is appropriate for both shop and field use by metal fabricators, pipefitters, HVAC sheet metal workers, and general maintenance technicians.

Designed for use with Quick Lok Type S-compatible grinders and die grinders. Optimized for mild steel surfaces. Verify tool spindle compatibility with the Type S locking system before installation.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and unplugged or with the air supply disconnected on pneumatic tools. Align the Type S button center with the tool's Quick Lok receptacle and twist to lock before applying power. Always inspect the disc for cracks or damage before use and confirm the tool RPM rating meets or exceeds the disc's maximum rated speed. Eye protection and appropriate PPE are required during all grinding operations per ANSI and OSHA standards.
