CGW 42872 4-1/2" X 7/8" Type 29 60-Grit XL PSG Ceramic Extreme II Flap Disc

The CGW 42872 flap disc is a 4-1/2 inch diameter, 7/8 inch arbor Type 29 configuration designed for aggressive grinding and finishing on metal and other tough materials. This disc uses PSG Ceramic grains, which are engineered to stay sharper longer, promoting faster material removal with a cooler operation and extended disc life. The 60-grit designation indicates a relatively coarse abrasive suitable for rapid deburring, stock removal, and shaping tasks where higher material throughput is desirable, while still delivering a quality finish typical of ceramic grains.

Constructed for durability in demanding shop environments, the disc combines PSG Ceramic grains with a robust backing and the Type 29 angle orientation that favors sloped surfaces and concave profiles. The result is a balance of aggressive cutting with controllable shaping, making it suitable for surface prep, weld bead blending, and deburring across steel and other ferrous alloys. As with ceramic-based products, users should monitor temperature buildup and inspect the disc for wear or glazing to maintain consistent performance.

This product is packaged as a single disk, with a box quantity of 10, and is compatible with standard 4-1/2 inch grinders equipped with a 7/8 inch arbor. When selecting replacement discs, ensure the abrasive type, grit, and disc angle alignment match the application needs. Regular inspection of the backing and attachment hardware will help preserve balance and machining accuracy during use.
