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 tool designed for metal finishing. This model, CR-ST, features a P120 X-weight grade that balances durability and cutting efficiency for various tasks.

Its straight format and case of 100 make it easy to stock up for ongoing projects. The brand’s reputation ensures consistent quality and performance across all rolls in the pack.

Precise Dimensions Matter

Each cartridge roll measures 3/8 inch by 2-1/2 inches by 1/8 inch, providing a compact size ideal for detailed work. These dimensions allow access to tight spaces where larger abrasives can’t fit.

The small size is perfect for corners and inside pipes, making this roll a versatile choice for finishing jobs that require precision in hard-to-reach areas.

Effective Grinding Aid Technology

This roll uses an anti-friction grinding aid that reduces grinding temperatures, helping the abrasive run smoothly. This feature prevents overheating and extends the life of the abrasive during use.

The grinding aid coating combined with the semi-flexible x-weight backing supports tough jobs by minimizing heat buildup and improving overall performance on metal surfaces.

Durable Multi-layer Design

The 3M Cartridge Roll 747D features a multi-layer, multi-wear design that enhances longevity. As the top layers wear down, fresh abrasive layers are exposed, maintaining a consistent cut throughout its use.

This closed-coat construction covers 100 percent of the cloth backing, ensuring a smooth finish and durability. The roll’s sturdy build supports repeated use without losing effectiveness.

Compatible Mandrel Attachment Format

The arbor hole on these rolls fits mandrel tool attachments, making them compatible with a variety of tools. This format allows easy installation and secure attachment during sanding or grinding.

Available in both straight and tapered designs, the roll’s format supports blending, deburring, and polishing in tight spots, enhancing its versatility for different metal finishing tasks.
