Arc Abrasives 71-31668 Surface Conditioning Disc 3 in 120 Grit

Product Description

The ARC ABRASIVES 71-31668 is a 3-inch surface conditioning disc designed for edge grinding applications on cold rolled mild steel and stainless steel sheet. It features an extremely flexible backing combined with a 100 percent cotton abrasive construction, which allows the disc to conform to irregular surfaces and contours during use. At 120 grit, it delivers a fine cut that suits surface prep, blending, and finishing work. Fabricators and metal finishing technicians reach for this disc when consistent surface contact and flexibility matter more than aggressive stock removal.

This disc is suited for edge grinding on cold rolled mild steel and stainless steel sheet stock, making it a practical choice in fabrication shops, metal service centers, and field finishing applications. The 100 percent cotton abrasive backing gives it a degree of flexibility that rigid fiber discs cannot match, which is particularly useful when working edges and transitions. It is sold in a minimum quantity of 50 units, making it appropriate for professional shop use where consistent supply of consumables is standard practice.
