Diamax Cyclone 4″ Backer Pad Thin Style (SKU BPT40)

The Diamax Cyclone 4″ Backer Pad Thin Style (SKU BPT40) is a professional-grade, compact backing pad designed to provide reliable support and stability for Velcro-backed polishing and grinding pads during stone fabrication, finishing, and installation tasks. Constructed with thin, soft rubber, this backer pad offers a degree of flexibility that allows it to conform to subtle curves, ogee edges, bullnose profiles, and other intricate stone details. This flexibility ensures consistent contact between the polishing or grinding pad and the stone surface, minimizing uneven finishes, chatter marks, or surface imperfections.

Its 4-inch diameter makes it ideal for precision work in tight or detailed areas, while still providing enough surface area to maintain effective polishing and grinding pressure. The thin style design allows operators to reach difficult-to-access edges and profiles, making it particularly useful for sink cutouts, inside radii, and decorative stone edges where larger or rigid backer pads may not perform well.

Equipped with a standard 5/8″‑11 threaded arbor, the BPT40 backer pad is compatible with most angle grinders, air polishers, and water-fed polishing machines, offering versatility across professional fabrication shops, on-site installations, and restoration projects. Its Velcro (hook-and-loop) attachment allows for quick, secure, and tool-free pad changes, helping to streamline workflow and reduce downtime.

This backer pad is designed for both wet and dry polishing and grinding applications, making it suitable for a wide range of stone types and conditions. Wet polishing helps cool the pad, reduce dust, and extend the life of polishing discs, while dry polishing provides portability and convenience for smaller adjustments or finishing tasks.
