• 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.

Trusted 3M Cartridge Roll

Durable Cloth Backing Benefits

The 60 X-weight cloth backing supports heavy sanding while fraying naturally to expose fresh abrasive layers. This feature extends the roll's cutting life and maintains effective sanding action.

Because the cloth backing is sturdy yet flexible, it withstands pressure and heat during use. This makes the cartridge roll suitable for demanding metalworking applications.

Effective Abrasive Technology

Aluminum oxide abrasive in a closed-coat layer provides fast cutting and long-lasting performance. This mineral is tough and self-fractures to reveal fresh edges, keeping the roll sharp.

The resin bond secures the abrasive firmly, resisting high heat and pressure. This combination ensures consistent sanding results across various materials, including ferrous alloys.

Convenient Pack Size

This product comes as a case of 100 cartridge rolls, offering great value and readiness for multiple projects. Having a large pack ensures you won’t run out during extensive sanding jobs.

The rolls attach to a compatible cartridge roll mandrel (sold separately), which fits rotary tools like die grinders or drills. This setup makes it easy to reach tight spaces efficiently.
