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 exact model. This cartridge roll is designed to meet demanding metal finishing needs, especially in tight spaces. Its reputation ensures consistent quality for professional use.

Ideal for small, hard-to-reach areas, this roll features a strong cotton backing and a solid mandrel core. The case of 100 rolls provides ample supply for ongoing projects, making it a practical choice for workshops and industrial settings.

Precise Size And Format

Measuring 3/4 inch by 1-1/2 inch by 1/8 inch, this cartridge roll fits perfectly in compact spaces. The straight format allows for smooth operation and easy handling during detailed grinding tasks.

These dimensions make the roll suitable for use with various tools, especially when working inside pipes or corners. The size ensures you can reach tight spots without sacrificing control or effectiveness.

Effective 80 X-weight Backing

The 80 X-weight backing provides a semi-flexible yet sturdy base for the abrasive material. This balance helps the roll maintain shape while adapting to contours, improving contact with the work surface.

This backing supports the abrasive’s durability, allowing it to withstand tough jobs without tearing. It also contributes to the smooth running of the roll, reducing user fatigue during extended use.

Durable 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 longevity, outperforming standard aluminum oxide abrasives.

Its multi-layer, multi-wear design ensures consistent cutting performance over time. As the top layers wear, fresh abrasive surfaces are exposed, maintaining efficiency throughout the roll’s life.

Convenient Case Of 100

Supplied in a case of 100, this cartridge roll pack supports large-scale or repeated projects without frequent reordering. The quantity suits professional environments where consistent supply is critical.

Having a full case on hand reduces downtime and keeps work progressing smoothly. This packaging also helps with organized storage and easy access to the rolls when needed.
