Arc Abrasives 31666 Surface Conditioning Disc 3 in 80 Grit

Product Description

The ARC ABRASIVES 31666 is a 3-inch surface conditioning disc designed for edge grinding and surface preparation work on metal. It features an extremely flexible backing combined with 100 percent cotton abrasive construction, allowing the disc to conform to contours during use. At 80 grit, it delivers moderate-to-aggressive stock removal suitable for blending, light deburring, and surface conditioning. This disc is a Type R mount, making it compatible with right-angle grinders and die grinders equipped with a mandrel. Fabricators, welders, and metal finishing technicians are the primary users of this consumable abrasive.

This disc is suited for use on cold rolled mild steel and stainless steel sheet stock. The flexible backing makes it particularly effective for edge grinding applications where a rigid disc would skip or chatter. It is sold individually, with a minimum order quantity of 50 units, making it appropriate for shops that consume abrasives at production volume. Light industrial and fabrication environments are the typical setting for this product.
