- 3 inch Hook & Loop backing plate with 6-hole dust collection and quick-change surface for fast swapping of sanding and polishing discs. The core is reinforced with steel struts to maintain balance during use. - 6-hole sander backing pad compatible with vacuum hole pneumatic sanders for dust extraction while sanding. Provides control and a consistent finish, with a soft beveled urethane edge to reduce marring. - Minimizes heat transfer: the polyurethane backing plate dampens vibration and reduces heat transfer from the polisher. Flexible, durable construction with a built-in mounting thread for quick and easy installation. - Easy installation and broad compatibility: works with hook & loop 3 inch sanding discs and 3-inch 6-hole sponge interface pads. Use scenarios: - Woodworking and furniture finishing: use with 3" discs to smooth surfaces and remove finish while maintaining a cleaner work area with dust collection. - Auto detailing and small-panel prep: compatible with pneumatic sanders for controlled material removal and dust extraction during polishing. - General small-part finishing: suitable for tight contours and curved surfaces where vibration damping and heat reduction improve consistency and finish quality.
