Arc Abrasives 71-10818FF Predator Type 27 Flap Disc 50 Grit

Product Description

The ARC ABRASIVES 71-10818FF Predator is a Type 27 flap disc engineered for aggressive material removal on metal surfaces. Measuring 4.5 inches in diameter with a 5/8-11 inch arbor, it operates at a maximum of 13,300 RPM. The overlapping abrasive flaps deliver fast, consistent stock removal while the disc conforms to the workpiece, reducing the need for secondary finishing passes. Each box contains 10 discs. This disc is well suited for fabricators, welders, and metalworkers who need to remove welds, blend surfaces, or deburr edges efficiently on production or job-site work.

The 71-10818FF Predator is designed for use on mild steel, high alloy steel, nickel alloy, and stainless steel. It is a practical choice for weld grinding and surface prep work in fabrication shops, structural steel, and maintenance environments. The Type 27 flat-profile design works well with standard angle grinders when the application calls for flat or curved surface work at moderate angles.
