3M™ Full Tapered Cartridge Roll 341D 3/8" x 1-1/2" x 1/8" Aluminum Oxide 80 Grt – Pkg Qty 100

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.

3M™ Cartridge Roll 341D has a closed coat of aluminum oxide abrasive secured with a heat-resistant resin bond. Cartridge rolls fit onto a cartridge roll mandrel (sold separately) and are ideal for accessing small, hard to reach spaces. 3M™ Cartridge Roll 341D is used in metalworking applications. Aluminum oxide is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut-rate, hardness, and strength, it is widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys. Heat-resistant resin is a sturdy binding agent that adheres the abrasive to the backing and maintains the stability of the bond even in conditions of high heat or pressure. Cartridge rolls fit onto a compatible mandrel (sold separately) that attaches to a rotary tool such as a die grinder or drill. Together, the mandrel and cartridge roll enable the user to grind or finish hard-to-reach areas of a work piece. To ensure correct fit, the center hole diameter of the cartridge roll must be equal to the diameter of the mandrel pilot inserted into the cartridge roll.
