The CGW 49521 4-1/2" x 7/8" Medium Smooth Resin Fibre Disc Back-Up Pad is designed to support coated abrasive discs during heavy grinding. The back-up pad provides a stable, compliant surface that helps achieve consistent contact with irregular workpieces, contributing to more even material removal and reduced dwell on the disc. Its medium smooth resin fibre construction supports a range of coarse grits, making it suitable for general purpose surface finishing and material preparation tasks.
Key features include spiral ribs that create defined contact points and air channels. This design promotes improved airflow, which helps dissipate heat and extend disc life by reducing loading and heat buildup. Larger air holes further enhance cooling, contributing to longer abrasive disc life and more predictable performance during extended use. The product offers flexible rubber pad options for contours and rigid pads for more aggressive grinding, allowing users to tailor the backing pad to the workpiece geometry and grinding aggressiveness.
This back-up pad is specified for 4-1/2 inch diameter discs with an 7/8 inch arbor/shank, rated at up to 11,000 RPM. Each unit is packaged individually, ready to install on compatible angle grinders and die grinders. When selecting pads, consider the workpiece contour, required rigidity, and cooling needs to optimize disc life and finish quality.
Features:
- Rubber Back-up Pads – Use with coarse grits.
- Spiral ribs provide contact points and form channels for air flow, extending disc life 30% to 50%.
- Larger air holes provide cooler operating area and longer abrasive disc life.
- Flexible Rubber Pads are recommended for contours and Rigid Pads will last longer on aggressive grinding applications
