Arc Abrasives 71-10823FF Predator Type 27 Flap Disc Grit 36

Product Description

The ARC ABRASIVES 71-10823FF is a Type 27 Predator flap disc engineered for aggressive material removal on metal surfaces. Measuring 4.5 inches in diameter with a 7/8-inch arbor hole and rated at 13,300 RPM, this disc is built for angle grinder use in demanding fabrication and weld-finishing applications. The 36-grit abrasive delivers fast stock removal while maintaining disc longevity. Each box contains 10 discs. The flat-profile Type 27 geometry allows flush grinding and is well suited for work on flat or contoured workpieces where consistent contact and controlled aggression are required.

This flap disc is designed for use on mild steel, high-alloy steel, nickel alloy, and stainless steel. It is a strong choice for weld seam removal, surface conditioning, and blending operations in metal fabrication shops, structural steel work, and maintenance welding environments. The 36-grit cut makes it particularly effective where fast weld bead removal or heavy stock removal is the primary task before finishing passes with finer grits.

Installation Notes

Install and use performed by metalworkers, welders, and fabricators familiar with angle grinder operation.
