The CGW 42306 is a 4-1/2" diameter, 7/8" arbor Type 27 zirconia flap disc designed for aggressive material removal on steel substrates. Its configuration pairs premium zirconia alumina grain with a poly/cotton backing, balancing durability with a smoother finish while maintaining high stock removal thanks to the zirconia’s inherent hardness. An active grinding aid supports cooler cutting under light pressure, helping manage heat buildup during prolonged grinding sessions.
This flap disc is engineered to deliver fast stock removal in demanding grinding applications, making it suitable for heavy-duty use where higher material throughput is required. The Type 27 profile provides a flatter grinding surface for more aggressive edge contact and controlled material removal on flat or simple curved surfaces. The 120-grit specification offers a balance between material removal rate and surface finish, which is important for preparing parts for finishing operations or subsequent processing.
For proper use, ensure compatibility with standard 4-1/2" angle grinders that accept 7/8" arbors. The package configuration lists individual discs with a box quantity of 10, catering to shop-level regrinding needs. Monitor disc wear and replace when removing past material to maintain consistent performance and surface quality.
