CGW 48221 5" X 5/8"-11 Medium Resin Fibre Disc Back-Up Pad

The CGW 48221 back-up pad is designed to support 5 inch resin fiber discs with a 5/8-11 arbor, enabling stable, high-efficiency grinding on a range of metal and similar substrates. The medium-density rubber back-up pad is paired with spiral ribs that create contact points while forming channels for air flow, which helps dissipate heat and extend abrasive disc life by an estimated 30% to 50% under typical use. Larger air holes further improve cooling, contributing to longer disc life and consistent grinding performance. When paired with coarse grits, the rubber option is recommended for contouring and profile work, while the rigid pad variant offers longer life on aggressive applications.

This back-up pad is specifically sized for a 5" diameter disc and a 5/8"-11 arbor, and it operates at up to 12,250 RPM as indicated by its specification. The combination of flexible rubber and the channeling design supports a balance between conformability and rigidity, helping users achieve uniform contact across irregular surfaces while maintaining disc stability. The packaging indicates the product is sold per each, allowing purchase to align with single-disk or broader project needs.

For best results, select the pad type (flexible rubber or rigid) based on the contouring requirements and grinding aggressiveness of the job. Maintain proper alignment and verify compatibility with the chosen resin fiber disc to ensure safe operation and optimal life of both pad and abrasive. Regular inspection for wear and proper seating on the arbor will help sustain performance over time.
