Arc Abrasives 37218 Resin Fiber Disc 7in X 7/8in 80 Grit

Product Description

The ARC ABRASIVES 37218 is a resin fiber disc engineered for aggressive material removal on steel, aluminum, and other non-ferrous metals. Measuring 7 inches in diameter with a 7/8-inch arbor hole, this disc pairs a durable resin-bonded backing with an 80-grit abrasive grain and an integrated grinding aid. The grinding aid reduces heat buildup during use, extending disc life and improving cut consistency. This disc is a standard tool for metal fabricators, welders, and maintenance technicians who need reliable surface conditioning and stock removal across a range of metalworking applications.

The 37218 is suited for use with 7-inch right-angle grinders in production and job-site environments. Its construction supports work on structural steel, sheet metal, and non-ferrous materials such as aluminum. The 80-grit designation places it in the medium-coarse range, appropriate for weld blending, deburring, and surface preparation ahead of finishing or coating. Sold in pack quantities, this disc is appropriate for shops and contractors managing regular abrasive consumption.
