CGW 42144 is a 4-inch diameter, 5/8-11 stud, Type 27 zirconia flap disc designed for aggressive material removal on steel. This disc uses premium zirconia alumina grain on a durable poly/cotton backing, combining robust stock removal with a smoother finish. The zirconia concentration enhances abrasive action, enabling efficient material removal while maintaining a relatively cool cut due to the active grinding aid, which helps reduce heat buildup under light pressure.
The Type 27 profile provides an angled grinding surface suited for contouring, edge work, and flat surfaces, making it a versatile choice for heavy-duty grinding tasks in metal fabrication and maintenance environments. The combination of grain, backing, and a-zirconia mix is intended to balance aggressive performance with manageable finishing characteristics, allowing operators to achieve material removal goals without excessive pressure.
This product is specified with a 4" diameter and a 5/8"-11 arbor size, compatible with standard angle grinders and compatible accessories. It is packaged in boxes of 10 discs, facilitating bulk usage in shop settings where high stock removal is required. When selecting this flap disc, consider the application material and desired balance between removal rate and surface finish, and choose appropriate wheel speed within the product’s rated RPM to maintain disc integrity and safe operation.
