Forney Industries Inc 71667 Resin Fibre Sanding Disc 24 Grit

Product Description

The FORNEY INDUSTRIES INC 71667 is a 3-pack of 4.5-inch resin fibre aluminum oxide sanding discs designed for use on right angle grinders. Each disc features a heavy vulcanized fibre backing coated with aluminum oxide abrasive grains bonded with a heat-resistant resin. This construction delivers fast cutting action and extended disc life. At 24 grit, these discs are suited for aggressive material removal tasks including weld grinding, blending, surface finishing, and deburring. Licensed tradespeople and fabricators in metal and composite work rely on this format for quick, repeatable results across a variety of base materials.

These discs are well suited to fabrication shops, job sites, and maintenance environments where right angle grinders are standard equipment. The 24 grit rating makes them appropriate for initial weld grinding and heavy stock removal before transitioning to finer abrasives. They perform on most types of steel as well as fiberglass and plastics, making them versatile across mixed-material work. The 7/8-inch arbor hole is the standard fit for common 4.5-inch right angle grinders used in HVAC, pipefitting, ironwork, and general fabrication trades.

Installation Notes

Disc mounting and removal should always be performed with the grinder unplugged or battery removed. Inspect each disc for cracks or damage before mounting. Follow the grinder manufacturer's maximum RPM rating and confirm the disc is rated at or above that speed before operation. Eye protection and appropriate PPE are required when operating abrasive discs on angle grinders.
