The 3M Cartridge Roll 747D is ideal for metal finishing in small hard to reach areas like corners or inside pipes. These cartridge rolls feature a blend of aluminum oxide and 3M ceramic grain on a strong cotton backing around a solid mandrel core. Available in both tapered and regular designs.

Blended Materials that Stay Sharp
The surface of the 3M Cartridge Roll 747D is covered with blended ceramic materials, which enhances the toughness and hardness of the grain. Perfect for stock removal, ceramic abrasives are engineered to fracture frequently for a super-fast cut and can handle intense heat and stress applications. The ceramic/aluminum oxide blend surpasses aluminum oxide abrasives in cut-rate and durability and makes our 3M Cartridge Roll 747D an excellent choice for moderate stock removal and surface preparation.

Sturdy Design for Tough Jobs
Abrasive grains are attached to the roll using an anti-friction resin bonding material, which helps the abrasive run smoothly over the workpiece. A grinding aid coating is also added to help the abrasive stay cool during grinding, minimizing heat and improving abrasive performance. This attribute, combined with the semi-flexible x-weight backing, make this roll a good match for projects that require a strong sanding tool that can be used with minimal space or leverage. Rolls can also be ordered with tapered ends. The tapered point and small size of tapered rolls enable you to get inside internal diameters and holes, making them great for deburring, blending and polishing in hard-to-reach areas.

Multi-layered Abrasive
The multi-layer design of our 3M Cartridge Roll 747D keeps it cutting sharp and helps it withstand repeated wear. As top layers wear down over time, underlying layers expose fresh mineral, so that you get a consistent cut on every job. Wrapping multiple layers of resin bonded abrasive material around the roll also contributes to its sturdiness and durability. The closed-coat construction means mineral grains cover 100 percent of the cloth backing, so that you get a smoother, more consistent finish. Seemingly small, these cartridge rolls conquer big challenges when space gets tight.

Trusted 3M Cartridge Roll

The 3M Cartridge Roll 747D, CR-ST is a reliable abrasive solution designed for metal finishing. This model features the exact specifications of P120 X-weight grade and a straight format, ensuring consistent performance for your projects.

Its design suits various tasks, especially where precision is needed. The case of 100 rolls provides ample supply for ongoing work, making it a practical choice for professionals and workshops alike.

Precise Size And Dimensions

Each roll measures 3/8 inch by 1-1/2 inch by 1/8 inch, offering a compact size that fits tight spaces. These dimensions make the cartridge roll ideal for detailed work in corners or inside pipes where larger abrasives can't reach.

The straight format of the roll supports smooth operation and easy handling. This size and shape combination helps users maintain control during grinding and finishing tasks.

Durable P120 X-weight Backing

The P120 X-weight backing provides a sturdy base that balances flexibility and strength. This backing supports the abrasive grains effectively, allowing the roll to withstand tough jobs without tearing or losing shape.

This semi-flexible backing also helps the roll conform to surfaces while maintaining durability. It’s especially useful when working in confined or awkward spaces where a rigid tool would be less effective.

Effective Abrasive Blend

The cartridge roll uses a ceramic aluminum oxide blend that breaks down to reveal sharp cutting edges. This mix enhances cutting speed and durability, outperforming standard aluminum oxide abrasives in many applications.

This abrasive combination is perfect for moderate stock removal and surface preparation. It handles heat and stress well, making it suitable for continuous use in demanding environments.

Convenient Case Of 100

Supplied in a case of 100, these cartridge rolls ensure you have enough material for multiple projects without frequent reordering. This pack size supports efficient workflow and reduces downtime.

The case format also helps keep the rolls organized and protected during storage. Having a large quantity on hand is ideal for professionals who rely on consistent abrasive performance daily.
