3M Cartridge Roll 341D, CR-ST, 80 X-weight, 3/8 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.

Trusted 3M Cartridge Roll

The 3M Cartridge Roll 341D is a reliable choice for sanding tasks. This model features the CR-ST grade and is designed to deliver consistent performance for metalworking and finishing jobs.

Its aluminum oxide abrasive ensures fast cutting and long life, making it suitable for professionals who need durable and effective abrasive rolls. The cartridge roll format fits specific mandrels for easy use.

Precise Size And Dimensions

This cartridge roll measures 3/8 inch by 1-1/2 inch by 1/8 inch, providing a compact size ideal for detailed work. These dimensions allow access to tight or hard-to-reach spaces during sanding and finishing.

The small size supports precision in metalworking applications, helping users achieve smooth finishes even in confined areas. Its straight shape maintains consistent contact with the work surface.

Durable Cloth Backing Support

The roll uses a cloth backing that supports heavy sanding while gradually fraying to expose fresh abrasive layers. This feature extends the life of the cartridge roll and maintains cutting efficiency.

Cloth backing also adds flexibility, which helps the roll conform to irregular surfaces. This makes it easier to sand complex shapes without losing abrasive effectiveness.

Heat-Resistant Resin Bond

A heat-resistant resin bond secures the aluminum oxide abrasive to the backing. This bond withstands high heat and pressure, ensuring the roll remains stable during demanding sanding tasks.

The resin bond's durability helps prevent premature wear or detachment of abrasive grains. This makes the cartridge roll suitable for use with rotary tools that generate significant friction and heat.

Convenient Pack Of 100

This product comes as a case of 100 cartridge rolls, providing ample supply for ongoing projects. The pack size supports frequent replacement and reduces downtime during work.

Cartridge rolls attach to compatible mandrels (sold separately), making them easy to swap out during sanding. Having a large pack ensures users can maintain productivity without running short.
