CGW 42721 7" X 7/8" Type 29 36-Grit Z3 Zirconia Flap Disc

The CGW 42721 is a 7 inch diameter, 7/8 inch arbor Type 29 zirconia flap disc designed for aggressive material removal on steel surfaces. This disc features premium zirconia alumina grain bonded to a durable poly/cotton backing, delivering a balance of stock removal and finish quality. The zirconia concentration provides high grinding efficiency, suitable for demanding grinding tasks, while the active grinding aid helps maintain cooler cutting under light pressure.

Constructed to handle heavy duty applications, this flap disc is intended for aggressive use where rapid material removal is desired. The Type 29 profile offers a more aggressive grinding angle and flexibility for contoured surfaces, aiding in efficient deburring and weld removal. The combination of grit 36 on a 7" wheel with an 7/8" arbor makes it compatible with standard air-driven right-angle grinders used in metal fabrication and maintenance environments. Packaging specifies 10 discs per box, with each disc designed for typical workshop or facility maintenance workflows requiring fast stock removal on steel.

When selecting this disc, consider the balance between material aggressiveness and the need for a quality finish. The 36-grit zirconia flap disc is most effective on ferrous metals where high stock removal is needed, and the Type 29 profile helps reach into bevels and weld beads. Ensure proper grinding technique and use with appropriate safety PPE. This product is listed with the CGW part number CGW42721 and is sold in box quantities of ten pieces per package.
