3M Cubitron 46873-case Cartridge Roll 341D, 1" x 1-1/2" x 1/4", 50 X-Weight (Pack of 50)

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)
