Arc Abrasives 71-31464 Quick Lok Disc Type S 3in Grit 50

Product Description

The ARC ABRASIVES 71-31464 is a 3-inch Quick Lok abrasive disc designed for use with Type S mechanical locking systems. The Type S button center locks the disc onto the tool with a simple twist, ensuring secure seating during grinding and finishing operations. Built around self-sharpening abrasive grains, this disc continuously exposes fresh cutting edges as it wears, making it a cost-effective alternative to full ceramic abrasive materials. Each box contains 50 discs. Licensed HVAC techs, metalworkers, and general trade professionals will find this disc well suited to material removal and surface prep tasks on mild steel.

This disc is intended for light to medium grinding and surface conditioning on mild steel applications. The self-sharpening grain structure supports consistent stock removal over the life of the disc without requiring frequent changeovers. The 3-inch diameter fits compact angle grinders and die grinders equipped with a Type S quick-lock spindle. It is a practical choice for fabrication shops, field service work, and maintenance grinding where cost per disc matters.
