Arc Abrasives 71-31463 Quick Lok Disc Type S 3in Grit 40 50pk

Product Description

The ARC ABRASIVES 71-31463 is a 3-inch Quick Lok abrasive disc with a Type S mechanical locking center, sold in boxes of 50. The Type S button system locks the disc onto the tool with a simple twist, providing secure positioning during use. Designed around self-sharpening abrasive grains, this disc continually exposes fresh cutting edges as it wears, making it a cost-effective alternative to full ceramic abrasive discs. It is sized at 3 inches in diameter and carries a 40-grit designation for aggressive stock removal. Grinding technicians and fabricators in metal finishing, weld blending, and surface prep will find this disc well suited to production environments where cost per disc matters.

This disc is intended for use on mild steel surfaces in light fabrication, maintenance, and repair applications. The 40-grit cut is appropriate for fast material removal, deburring, and weld seam grinding. The Type S Quick Lok mount is compatible with angle grinders and die grinders fitted with a matching Quick Lok or Type S backing pad. Discs are packaged 50 per box, supporting high-volume shop use and reducing downtime from frequent restocking.
