3M 7100138284 Roloc Bristle Disc 2 Inch Medium Grit

Product Description

The 3M 7100138284 is a Roloc bristle disc designed for general-purpose scuffing and surface cleaning in trade and industrial applications. Built from a non-woven, three-dimensional material in a maroon medium-grit construction, it delivers flexible, consistent abrasive action without the rigidity of traditional abrasive wheels. The 2-inch diameter and 5/8-inch tapered hub mount directly to a Roloc-compatible holder, making disc changes fast during production work. This disc is particularly effective for accessing contoured or hard-to-reach surfaces where flat abrasives cannot conform. Weighing 0.55 pounds per box, the discs are lightweight and easy to handle throughout a shift.

This bristle disc is suited for machine scuffing, light cleaning, and surface preparation on metal, painted, and composite surfaces in fabrication shops, HVAC ductwork finishing, plumbing fixture prep, and general mechanical service environments. The non-woven construction resists loading and maintains consistent cut throughout the disc life. It is compatible with the 3M holder model 7500 for tool-mounted use, enabling quick disc swaps without additional hardware. Sold in a box with a minimum quantity of 4 discs per order.
