3M 051141-20421 Full Taper Coated Cartridge Roll, 3/8 in Dia x 2-1/2 in L, 1/8 in, 150 Grit, Aluminum Oxide Abrasive

3M™ Cartridge Roll 341D gives you easy access to small, hard-to-reach spaces for sanding and finishing. As the outermost abrasive layer wears down, the cloth backing frays to expose fresh abrasive layers for continued cutting action.

• Small size is ideal for sanding and finishing hard-to-reach spaces
• Cloth backing supports heavy sanding yet frays to expose fresh abrasive
• Resin bond withstands high heat and pressure
• Aluminum oxide abrasive in a closed-coat layer provides fast cut and long life
• Rolls attach to a compatible cartridge roll mandrel (sold separately)
