Arc Abrasives 71-10813FF Predator Flap Disc Type 27 Grit 36

Product Description

The ARC ABRASIVES 71-10813FF Predator Flap Disc is a Type 27 abrasive grinding disc designed for aggressive material removal and long service life on metal fabrication applications. Measuring 4.5 inches in diameter with a 5/8-11 inch arbor fitting, this disc operates at a maximum of 13,300 RPM. The Predator series is built for fast weld removal while maintaining disc longevity that outperforms standard flap disc options. Each box contains 10 discs. Licensed welders, metal fabricators, and maintenance tradespeople rely on this disc for consistent, high-rate stock removal across a range of ferrous and non-ferrous metals.

This flap disc is well suited for use on mild steel, high alloy steel, nickel alloy, and stainless steel. Its Type 27 flat profile makes it effective for flat surface grinding and weld blending. Typical install scenarios include weld seam removal, surface prep before coating, and edge cleanup on fabricated assemblies. The 36-grit coarseness targets heavy material removal passes rather than fine finishing work. This disc is commonly used in fabrication shops, structural steel work, and field repair environments where throughput and disc life are both critical.

Installation Notes

Flap discs of this type are installed and replaced by metal fabricators, welders, and maintenance technicians. Always power down and disconnect the grinder from its power source before mounting or removing a disc. Verify the tool spindle speed does not exceed the 13,300 RPM disc rating before operation. Inspect the disc for damage before each use and discard any disc that shows cracking, delamination, or missing flaps.
