CGW 42574 5" X 5/8"-11 Type 29 60-Grit XL Z3 Zirconia Flap Disc

CGW 42574 is a 5-inch diameter, 5/8-11 hub, Type 29 zirconia flap disc designed for aggressive material removal on steel. The disc combines premium zirconia alumina grain with a poly/cotton backing to balance durability with a smoother finish. Zirconia provides high stock removal rates, making this flap disc well-suited for heavy-duty grinding tasks where fast material removal is desired. An active grinding aid is included to help maintain cooler cutting under light pressure, which can contribute to longer-disc life and reduced heat-affected zones during extended grinding sessions.

Constructed as a Type 29 angle-grind disc, the design is intended for use on conventional right-angle grinders. The 60-grit specification positions it for substantial material removal while still delivering a workable surface finish on appropriate substrates. The product is packaged with ten discs per box and is compatible with standard 5/8-11 threaded arbor hardware common to many metalworking grinders. When selecting a flap disc for a given application, consider the substrate material, grinding force, and desired balance between material removal rate and surface finish; the zirconia blend in this disc is optimized for steel processing and aggressive grinding scenarios.

Proper use involves maintaining light to moderate pressure and allowing the disc to work rather than forcing the tool. Regular inspection for wear and disc integrity is advised, replacing discs showing edge cracking or glazing to avoid compromising performance or safety. The 5/8-11 thread and Type 29 configuration are standard for compatible right-angle grinders, but verify arbor compatibility with your specific tool before operation.
