The CGW 48239 is a 9 inch diameter, 5/8-11 threaded medium resin fibre disc back-up pad designed to support abrasive discs in high-speed grinding tasks. It serves as the backing component that anchors resin fibre discs and accommodates aggressive material removal while helping to manage heat and airflow during operation.
Construction features include spiral ribs that create contact points and form channels for air flow, which helps extend disc life by promoting cooling and reducing load on the abrasive surface. The pad’s larger air passages further enhance cooling, contributing to longer overall abrasive life by reducing heat buildup. Both flexible rubber and rigid pad variants are available in this style, with the flexible option recommended for contouring of curved workpieces and the rigid option offering longer wear in more aggressive grinding scenarios.
With a 9 inch diameter and 5/8-11 arbor size, this back-up pad is compatible with standard 9" resin fibre discs and is rated for up to 6600 RPM, aligning with typical high-speed shop grinders. The packaging is single unit per package, making it suitable for single-disk setups or replenishment on a per-tool basis. When selecting a back-up pad, consider the workpiece geometry and grinding aggressiveness to balance disc life with surface finish, and ensure the correct pad type (rubber vs rigid) for the job at hand.
