3M Cartridge Roll 341D, CR-ST, 80 X-weight, 1/2 in x 1-1/2 in x 1/8 in, Straight, Case of 100

• 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 Model Identification

The 3M Cartridge Roll 341D is a trusted product designed for precision sanding and finishing. This model, identified as CR-ST, features an 80 X-weight grade that balances durability and cutting efficiency.

3M is known for quality abrasives, and the 341D cartridge roll continues this tradition. Its specific model and grade make it suitable for various metalworking and woodworking tasks requiring fine control.

Dimensions For Precision

This cartridge roll measures 1/2 inch by 1-1/2 inches by 1/8 inch, offering a compact size that fits tight spaces. These exact dimensions allow users to access hard-to-reach areas with ease during sanding or finishing.

The small size is ideal for detailed work where larger abrasives can't reach. Its straight format ensures consistent contact with surfaces, improving the quality of the finish in confined spots.

Grade And Backing Benefits

The 80 X-weight grade provides a balance between aggressive cutting and long life. The cloth backing supports heavy sanding tasks while naturally fraying to expose fresh abrasive layers as the outer layer wears down.

This backing design extends the roll's usability by continuously revealing new abrasive surfaces. It also maintains flexibility and strength, which is essential for sanding uneven or curved surfaces.

Format And Compatibility Features

The cartridge roll format is designed to attach to a compatible cartridge roll mandrel, which is sold separately. This system allows easy installation on rotary tools like die grinders or drills for efficient sanding.

Using the cartridge roll with the correct mandrel ensures proper fit and function. The center hole diameter matches the mandrel pilot size, providing stability during operation and preventing slippage.

Pack Count And Usage

This product comes as a case of 100 rolls, making it convenient for professionals who require a large supply for ongoing projects. The quantity supports consistent workflow without frequent reordering.

Having 100 rolls on hand is practical for metalworking applications where multiple small abrasive tools are needed. The pack size also offers cost efficiency for bulk purchasing.
