Arc Abrasives 71-10813AF Predator Flap Disc Grit 36

Product Description

The ARC ABRASIVES 71-10813AF is a hard-edge flap disc engineered for aggressive material removal and extended service life on metal fabrication and welding applications. Measuring 4.5 inches in diameter with a 5/8-11 arbor, it runs at a maximum of 13,300 RPM. The Predator series uses a high-density flap construction that delivers fast weld removal while maintaining disc integrity through the full working life. Each box contains 10 discs. This product is used by welders, fabricators, and metalworkers who need consistent cut rate across production work.

The 71-10813AF is suited for grinding and blending on mild steel, high alloy steel, nickel alloy, and stainless steel. The hard-edge design makes it effective at edge work, weld seam removal, and surface conditioning where a conformable disc would wear prematurely. It fits standard 4.5-inch angle grinders with a 5/8-11 threaded spindle, making it compatible with the most common grinders found in fabrication shops and on job sites.
