About This Product

Flexible Backer Pads for Curved Surfaces

Alpha® Flexible Backer Pads conform to tough contours, inside curves, tight corners, and other shaped surfaces. Unlike a rigid polishing plate, the flexible construction follows the workpiece to support controlled contact in areas that are difficult to polish with a flat backing surface.

Hook-and-Loop Accessory Attachment

The hook-and-loop face accepts compatible polishing pads, sandpaper, and felt wheels for a variety of finishing applications. This versatile polishing backing pad allows accessories to be attached and changed without requiring a separate backer for each surface-finishing process.

4" and 5" Polisher Backing Pads

This listing includes 4" and 5" polisher backing pad options, both featuring a standard 5/8"-11 thread. The common connection fits many compatible polishers and grinders used by stone fabricators, tile contractors, monumentalists, and restoration professionals.

Durable 6,000 RPM Construction

Each flexible backer pad is built for regular polishing and finishing work while maintaining the flexibility needed for shaped surfaces. Both available sizes have a maximum operating speed of 6,000 RPM; always match the accessory diameter, spindle thread, and speed rating to the tool before use.
