CGW 43081 4-1/2" X 7/8" Type 27 36-Grit Calcium Stearate Coated Flap Disc For Aluminum

The CGW 43081 flap disc is a 4-1/2 inch diameter, 7/8 inch arbor, Type 27 grinding disc designed for aluminum and other non-ferrous materials. It features a 36-grit aluminum oxide abrasive with a calcium stearate coating. This special treatment helps keep temperatures down during grinding and reduces loading when working with soft metals, which can improve surface finish and keep disc performance more consistent during extended use.

The aluminum oxide abrasive combined with the calcium stearate additive is selected to address heat buildup and loading tendencies that are common with non-ferrous metals. The Type 27 back-angled design provides an aggressive grinding angle, making it suitable for contouring, blending, and deburring on curved surfaces and edges typical in aluminum parts and assemblies. The disc is manufactured to CGW specifications and is shipped in a packaging unit of 10 discs per box, with a 13,300 RPM operating speed rating appropriate for standard portable grinders when used within manufacturer guidelines.

When selecting this flap disc, ensure compatibility with your tool arbor size (7/8 inch) and confirm your application aligns with non-ferrous grinding needs. Regular inspection for wear and loading is recommended, and follow all safety practices for flap disc use, including guarding and personal protective equipment. This product is categorized for facility maintenance and is well-suited for aluminum finishing tasks, including deburring, edge blending, and light material removal on non-ferrous components.
