Arc Abrasives 71-31468 Quick Lok Disc Type S 3in Grit 120

Product Description

The ARC ABRASIVES 71-31468 is a Quick Lok abrasive disc designed for fast, secure mounting on angle grinders and die grinders equipped with a Type S quick-change arbor. The Type S mechanical locking button centers the disc on the tool with a single twist, eliminating the need for wrenches or backing pad hardware. At 3 inches in diameter with a 120-grit cut, this disc is engineered for finish grinding and light stock removal on mild steel. Each box contains 50 discs, making it a practical choice for shops and field technicians who cycle through abrasives at volume. The self-sharpening grain structure maintains consistent cut rate as the disc wears.

This disc is well suited for deburring, blending welds, and surface preparation on mild steel in fabrication, maintenance, and light industrial applications. The 120-grit rating targets finish work rather than aggressive material removal, making it appropriate for situations where surface condition matters after grinding. Metalworkers, pipefitters, and maintenance technicians working in residential, commercial, and industrial settings will find this disc a cost-effective alternative to full ceramic abrasive options.
