Arc Abrasives 71-10816FF Predator Flap Disc Type 27 Grit 80

Product Description

The ARC ABRASIVES 71-10816FF is a Type 27 flap disc designed for aggressive material removal on ferrous and non-ferrous metals. Sold in a box of 10, each disc measures 4.5 inches in diameter with a 5/8-11 inch threaded arbor and carries an 80-grit abrasive rating. Rated at 13,300 RPM, these discs are built for angle grinder applications where fast stock removal and extended disc life are both priorities. Fabricators, welders, and metal finishing technicians reach for this disc when weld seams, slag, and surface scale need to come off quickly without burning through discs.

This disc is well suited for work on mild steel, high alloy steel, nickel alloy, and stainless steel. The Type 27 flat profile keeps the abrasive surface flush to the workpiece, making it effective for flat stock, weld bead leveling, and surface blending in fabrication shops and field welding environments. The 80-grit designation targets medium-aggressive stock removal, sitting between coarse shaping work and fine finishing passes.
