Bihui 4" (100mm) Rubber Backing Pad (M14 Thread)

The Bihui 4" (100mm) Rubber Backing Pad is a professional-grade, highly durable support accessory engineered to anchor diamond polishing pads firmly to standard power tools. Designed specifically for tilers, stone fabricators, and masonry specialists, this premium backing pad bridges the connection between your angle grinder and finishing pads. Constructed from high-grade, semi-flexible rubber, it provides the perfect structural balance—offering enough rigidity for flat surface flattening while retaining the precise flex needed to follow elegant bevelled contours and curved profiles without gouging the stone.

Why Choose the Bihui 4" Rubber Backing Pad?

• Heavy-Duty M14 Thread Connection: Engineered with a precision-machined, standard M14 female brass thread, this backing pad spins directly onto any professional variable-speed angle grinder or stone polisher. The direct mount eliminates the need for loose adapters, ensuring vibration-free rotation at high speeds.

• High-Grip Velcro Connection Face: The working front face features a commercial-grade hook-and-loop (Velcro) lining. This layout is highly optimised to form a tight mechanical lock with all standard 4-inch diamond polishing pads, completely preventing pad slippage or dangerous detachment under heavy lateral friction.

• Semi-Flexible Rubber Compound: Unlike rigid plastic backers that can cause harsh skipping or deep scratches, the specialized rubber core absorbs operational shock. This flexible design allows the operator to execute flawless bevelled edges, custom mitres (jolly edges), and smooth bullnose curves effortlessly.

• Perfect 4-Inch Product Pairing: This backing pad is explicitly designed to pair seamlessly with the Bihui 4" Dry Diamond Polishing Pad series (Grits 50 through 1500), creating a perfectly flush boundary that ensures uniform grit wear and an immaculate factory finish.

• Broad Utility across Multi-Material Finishing: An essential component for any polishing kit, this robust backer supports tasks across a diverse range of hard wall and floor coverings:

  • White and light-tinted porcelain and ceramic tile profiles

  • Polishing edges on natural stone slabs (marble, granite, limestone)

  • Refacing engineered quartz, stone countertops, and masonry trims
