Arc Abrasives 71-10817AF Predator Flap Disc Grit 120

Product Description

The ARC ABRASIVES 71-10817AF is a hard-edge Predator 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 inches threaded arbor, this disc runs at a maximum speed of 13,300 RPM and carries a Grit 120 abrasive surface. It is designed for use on angle grinders and is the tool of choice for licensed welders, fabricators, and metalworkers who need fast weld seam removal without sacrificing disc longevity. Each box contains 10 discs.

This flap disc is well suited for grinding, blending, and finishing operations on mild steel, high alloy steel, nickel alloy, and stainless steel. The hard-edge construction makes it particularly effective on flat surfaces and outside edge work where consistent contact and aggressive stock removal are required. It is commonly deployed in structural steel fabrication shops, pipe welding operations, and maintenance and repair environments where downtime between disc changes is a direct cost concern.
