Arc Abrasives 31656 Surface Conditioning Disc 2in 120G

Product Description

The ARC ABRASIVES 31656 is a 2-inch Type R surface conditioning disc designed for edge grinding and surface prep work on metal. It features an extremely flexible backing combined with 100 percent cotton abrasive construction, which allows the disc to conform to contours and edges without loading or gouging the workpiece. At 120 grit, it delivers a medium-fine finish suitable for cleaning, blending, and light stock removal. This disc is a standard tool in metal fabrication and finishing workflows handled by welders, machinists, and metal fabricators.

The 31656 is engineered for edge grinding applications on cold rolled mild steel and stainless steel sheet. The flexible backing makes it well suited for reaching tight edge profiles and transitions where rigid abrasives would skip or dig. It is sold individually (each) with a minimum order quantity of 100 units, making it a practical choice for shops and contractors stocking abrasive consumables in volume.
