3-inch Hook & Loop Backing Plate — 6-Hole Dust Collection, Reinforced Steel Core Why you need this backing plate Faster disc changes and secure hold: Hook & loop face lets you swap 3-inch sanding or polishing discs quickly for uninterrupted work. Cleaner, more consistent sanding: Six dust-extraction holes pair with vacuum-capable pneumatic sanders to remove debris, improve visibility, and help achieve an even finish. Reduced vibration and heat: Polyurethane construction dampens vibration and minimizes heat transfer from the tool to the workpiece, extending disc life and improving comfort. Key features and benefits Size and fit: 3-inch diameter, compatible with standard 3" hook & loop sanding discs and 3" 6-hole sponge interface pads. Dust extraction ready: Six-hole layout aligns with vacuum hole pneumatic sanders for active dust collection and better surface control. Reinforced core: Steel struts in the plate’s core maintain balance during operation for smoother, wobble-free sanding and polishing. Soft, beveled urethane edge: Provides a forgiving contact surface at edges and contours, helping prevent gouging and promoting a uniform finish. Durable, flexible material: Polyurethane construction resists wear while remaining flexible enough to follow slight contours. Quick installation: Built-in mounting thread allows fast attachment to compatible polishers and sanders. Practical use scenarios Automotive paint prep: Use with 3" sanding discs on a pneumatic sander to remove blemishes, feather edges, and capture dust for a cleaner workspace and better paint adhesion. Wood and finish work: Ideal for detail sanding on cabinetry, trim, and curved surfaces where balance and reduced heat help prevent burn marks and surface damage. Polishing and restoration: Attach polishing pads for buffer work on small panels or components where vibration dampening and edge protection improve control and finish quality.
