3M 7100178266 Quick Change Fibre Disc 36 Grit 4.5 in

Product Description

The 3M 7100178266 is a coated quick-change fibre disc designed for aggressive material removal on carbon steel. Built on a stiff fibre backing with a strong resin bond, it uses 3M Precision Shaped Grain technology to deliver higher cut rates and longer service life compared to conventional abrasive discs. At 4.5 inches in diameter and 36 grit, it is sized for angle grinders and suitable for heavy-duty tasks such as weld removal, beveling, edge chamfering, and surface blending. Licensed HVAC and fabrication tradespeople working in metal prep and weld-finishing operations will find this disc a reliable production-grade consumable.

This disc is well suited for industrial and trade environments where rapid stock removal on carbon steel is required. Typical applications include weld grinding, bevel preparation, and finish blending on structural steel, pipe, and plate. The quick-change mounting system is compatible with 3M disc pad face plates and hubs sold separately, making swap-outs fast during continuous production work. It is sold in individual units and is appropriate for both shop and field use by metalworkers, pipefitters, and fabricators.
