Description

The FORNEY INDUSTRIES INC 71668 is a 3-pack of 4.5-inch resin fibre sanding discs designed for use on right angle grinders. Each disc is constructed with a heavy vulcanized fibre backing and coated with aluminum oxide abrasive grains bonded with a tough, heat-resistant resin. This construction delivers fast cutting action and extended service life. At 36 grit, these discs are built for aggressive stock removal, weld grinding, blending, finishing, and deburring tasks common in fabrication and field repair work. HVAC technicians, pipefitters, welders, and general trade professionals reach for these when surface prep speed matters.

These discs are suited for both residential and commercial job site applications. They perform on most types of steel as well as fiberglass and plastics, making them versatile for ductwork prep, pipe fitting, structural steel work, and general fabrication. The 7/8-inch arbor fits standard right angle grinder spindles commonly found in trade shops and on job sites. Each pack contains 3 discs, providing enough supply for extended work sessions without frequent restocking.
