Product Description

 

• This 100mm (4-inch) aluminum backer pad is designed for professional polishing, sanding, and buffing applications. Made from high-grade aluminum alloy, it ensures durability and heat dissipation during high-speed operations (up to 12,000 RPM). The dual-thread design (M14 & M16 for European tools, 5/8"-11 for North American tools) makes it compatible with most angle grinders and polishers. The precision-machined flat surface ensures even pressure distribution, reducing swirl marks and improving finish quality. Ideal for metal polishing, automotive detailing, wood sanding, and stone refinishing
