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

3M Cartridge Roll 341D provides 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 workpiece. 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.

Brand And Model

Known for quality, 3M ensures the cartridge roll meets industrial standards. The CR-ST grade offers a balance of cutting efficiency and durability for various applications.

Grade And Backing Benefits

This cartridge roll features a P240 X-weight grade, providing a fine abrasive surface ideal for finishing work. The cloth backing supports heavy sanding while allowing the roll to fray and expose fresh abrasive.

The cloth backing's design extends the life of the roll by revealing new abrasive layers as the outer surface wears down. This makes it suitable for detailed sanding and finishing tasks.

Dimensions And Size

Measuring 1/2 inch by 1-1/2 inches by 1/8 inch, this cartridge roll is compact and perfect for small, hard-to-reach spaces. Its straight format allows precise control during sanding.

The small size makes it ideal for finishing tight spots where larger abrasives can't reach. This dimension ensures versatility in metalworking and woodworking projects.

Format And System Use

The cartridge roll format fits onto a compatible cartridge roll mandrel, which is sold separately. This system allows easy attachment to rotary tools like die grinders or drills.

Using the roll with the mandrel enables efficient sanding in confined areas. The straight format supports consistent contact with the workpiece for smooth finishing.

Pack Count And Value

This product comes as a case of 100 cartridge rolls, providing excellent value for frequent users. Having a large pack ensures you have plenty of rolls for ongoing projects.

Buying in bulk reduces downtime caused by frequent replacements. The case count supports industrial or workshop environments where sanding is a regular task.
