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 offers reliable performance with its well-known brand and model. This cartridge roll is designed for metal finishing tasks, especially in tight spaces where precision matters.

Its CR-ST grade and 80 X-weight backing ensure durability and consistent results. This case of 100 rolls provides plenty of supply for ongoing projects.

Precise Size And Format

Each roll measures 1/4 in x 1 in x 1/8 in, making it ideal for detailed work in small areas. The straight format allows for easy handling and effective grinding in confined spaces.

This size fits well for tasks like deburring and polishing inside pipes or corners, where larger tools can't reach effectively.

Enhanced Abrasive Materials

The cartridge roll features a blend of ceramic aluminum oxide minerals that break down to reveal sharp cutting edges. This mix improves cutting speed and durability compared to standard aluminum oxide abrasives.

These materials are perfect for moderate stock removal and surface preparation, handling heat and stress without losing effectiveness.

Multi-Layer Abrasive Design

With a multi-layer, multi-wear construction, the 3M Cartridge Roll 747D maintains sharpness over time. As the top layers wear away, fresh abrasive layers become exposed, ensuring a consistent cut throughout its use.

The closed-coat design covers 100 percent of the cloth backing, providing a smooth finish and enhancing the roll’s longevity during tough jobs.

Compatible Arbor Hole Size

The roll includes an arbor hole that fits mandrel tool attachments, making it compatible with a variety of tools. This feature adds versatility to the cartridge roll’s use across different grinding setups.

Its sturdy design and anti-friction grinding aid help reduce heat buildup, allowing the abrasive to run smoothly and extend its life during demanding tasks.
