3M 7100284531 Hook Loop Disc 80 Grit 5 in Ceramic

Product Description

The 3M 7100284531 is a 5-inch hook-and-loop ceramic abrasive disc designed for aggressive material removal and smooth finishing on a wide range of surfaces. Built on a J-weight cotton cloth backing, this disc delivers the flexibility needed to conform to contoured workpieces while maintaining consistent cut rate. The ceramic abrasive grain runs at a medium-fine grade with 80 grit, making it well-suited for stock removal, surface prep, and blending tasks. The disc is rated to 12,000 RPM and features vacuum holes for dust extraction compatibility. Part of the 3M 900DZ series, it is designed for use with hook-and-loop backing pads on random orbital and angle-head sanders.

This disc is used in fabrication shops, finishing operations, and general surface preparation work. It performs well on metal, wood composites, and painted surfaces where controlled material removal and a smooth end result are required. The purple ceramic grain resists loading and maintains cutting performance over the life of the disc. Installation is tool-free with any compatible hook-and-loop backing pad. Tradespeople and industrial finishing technicians commonly use this disc during weld seam blending, paint prep, and sanding operations prior to coating application.

Installation Notes

This disc is installed by pressing the hook-and-loop face firmly onto a compatible 5-inch backing pad. Confirm the backing pad and tool are rated to at least 12,000 RPM before use. Inspect the disc for tears or delamination before mounting. Never exceed the maximum RPM rating marked on the disc or tool.
