The 3M™ Cartridge Roll 747D is designed with a surface covered in blended ceramic materials, which enhances the toughness and hardness of the grain. 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, making 3M™ Cartridge Roll 747D an excellent choice for moderate stock removal and surface preparation.
Sturdy Design for Tough JobsThe abrasive grains of the 3M™ Cartridge Roll 747D 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, which enable you to get inside internal diameters and holes, making them great for deburring, blending, and polishing in hard-to-reach areas.
Multi-layered AbrasiveThe 3M™ Cartridge Roll 747D is designed with a multi-layered abrasive that 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. These cartridge rolls are small but mighty, conquering big challenges when space gets tight.
