3M 7000000770 Radial Bristle Disc 2 Inch 80 Grit

Product Description

The 3M 7000000770 is a Scotch-Brite SR Radial Bristle Disc engineered for light sealant removal on contoured and hard-to-reach surfaces. The disc features ceramic abrasive particles embedded in flexible, spring-like plastic bristles that conform to irregular substrates. At 2 inches in diameter with an 80-grit rating, this curved disc delivers controlled cutting action without compromising the integrity of the underlying part. It is used by auto body technicians, sheet metal workers, and maintenance professionals who need precision seam sealant removal without chemical compounds.

This disc is designed for seam sealant removal in automotive, aerospace, and industrial maintenance applications. The flexible bristle design is particularly effective in tight corners, recesses, and curved panels where rigid abrasives cannot reach. Each package contains 40 discs along with Roloca attachment accessories, including plastic buttons and holders. Compatible mandrels, the 3M 990 and 3M 991, are sold separately and allow the disc to be mounted on either a straight grinder or a right-angle grinder.
