3M Cartridge Roll 341D, CR-FT, 80 X-weight, 3/8 in x 1-1/2 in x 1/8 in, Full Tapered, 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.

3M Cartridge Roll Model

The 3M Cartridge Roll 341D is designed for precision sanding and finishing tasks. This model features a full tapered format that fits well in tight spaces, making it a reliable choice for detailed work.

Its compatibility with cartridge roll mandrels (sold separately) allows for easy attachment to rotary tools. The case includes 100 rolls, providing ample supply for various projects.

Aluminum Oxide Abrasive Benefits

This cartridge roll uses aluminum oxide abrasive in a closed-coat layer, which ensures a fast cut and long life. The abrasive material is tough and self-fractures to expose fresh cutting edges during use.

Such properties make it ideal for metalworking and woodworking applications, especially when working with ferrous alloys. The abrasive maintains performance even under demanding conditions.

Durable Cloth Backing Support

The 80 X-weight cloth backing supports heavy sanding while fraying naturally to reveal fresh abrasive layers. This feature extends the roll's cutting action and overall lifespan.

Its sturdy backing makes the roll suitable for finishing hard-to-reach areas, ensuring consistent results in detailed sanding tasks. The cloth backing also adds flexibility during use.

Precise Dimensions For Use

Each roll measures 3/8 inch by 1-1/2 inches by 1/8 inch, providing a small size perfect for accessing tight spaces. These dimensions help users reach areas that larger abrasives cannot.

The full tapered shape complements these dimensions, allowing for smooth sanding and finishing in confined spots. This size is especially useful for intricate metalworking projects.

Heat-Resistant Resin Bond

The resin bond used in the 3M Cartridge Roll 341D withstands high heat and pressure, keeping the abrasive securely attached to the backing. This durability ensures consistent performance during heavy use.

This heat-resistant bond is crucial when working with rotary tools that generate friction and heat. It helps maintain the roll's integrity and effectiveness over time.
