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 is a reliable abrasive solution designed for metal finishing. This model, CR-ST, features an 80 X-weight backing that balances flexibility and durability for various tasks.

Ideal for detailed work, this cartridge roll comes in a case of 100, ensuring you have plenty of supply for ongoing projects. Its consistent quality makes it a staple for professionals needing dependable abrasives.

Precise Dimensions Enhance Use

Measuring 3/8 inch by 1 inch by 1/8 inch, this cartridge roll fits perfectly in tight spaces. The straight format allows for smooth operation on flat and curved surfaces alike.

These dimensions make it especially useful for reaching corners or inside pipes, where larger tools can’t fit. The size supports detailed deburring and polishing tasks with ease.

Effective Abrasive Material Blend

This roll uses a ceramic aluminum oxide blend that breaks down to reveal sharp cutting edges. This blend outperforms standard aluminum oxide abrasives in both cut-rate and durability.

Thanks to this material, the 3M Cartridge Roll 747D handles moderate stock removal and surface preparation efficiently, making it a versatile choice for metal finishing jobs.

Strong Backing Supports Performance

The 80 X-weight backing provides a sturdy yet semi-flexible base for the abrasive grains. This design helps the roll maintain its shape while adapting to the contours of the workpiece.

Combined with the anti-friction grinding aid, the backing reduces heat buildup and improves smoothness during use. This makes the roll suitable for tough jobs requiring precision and control.

Convenient Case Pack Count

Supplied in a case of 100 rolls, this product ensures you have enough material for extended projects or multiple users. The pack size supports efficient workflow without frequent reordering.

Having a large quantity on hand is especially helpful in industrial or workshop settings where consistent abrasive quality and availability are critical.
