Product Description

The FORNEY INDUSTRIES INC 71663 is a resin fibre sanding disc designed for aggressive material removal on metal, weld seams, and other tough surfaces. Built with aluminum oxide abrasive, this disc delivers consistent cut rate and long service life across a range of grinding and finishing tasks. It measures 5 inches in diameter with a 7/8 inch arbor hole and is rated at 80 grit, placing it in the medium-coarse range suitable for blending welds, removing mill scale, and surface prep before coating. The resin fibre backing provides the flexibility and durability needed to handle contoured and flat workpieces alike. Each package contains 25 discs.

This disc is used in metal fabrication, welding shops, and general industrial maintenance where consistent stock removal is required. The 5 inch diameter fits standard angle grinders equipped with a 7/8 inch arbor. At 80 grit, it is well suited for prep work prior to painting or coating, removing rust and corrosion, and smoothing weld beads on carbon steel and other ferrous metals. Trades that commonly use this disc include welders, pipefitters, ironworkers, and maintenance technicians.
