PRODUCT FAQ
-
What exactly is the 3M™ Cartridge Roll 747D?
The 3M™ Cartridge Roll 747D is a high-quality abrasive designed for aggressive sanding and finishing of small parts, contours, and hard-to-reach areas.
-
Can it be used on various materials?
Yes! It works on metals like aluminum and carbon steel as well as many plastics and composites.
-
How long does each roll last?
That depends on usage, but generally they have a longer life than conventional abrasives due to their larger contact area that reduces loading or clogging in the tool.
-
In what sizes are these available?
The size we offer is measuring at 3/4 inch by 1-1/2 inch by an eighth-inch thickness.
-
Is this product safe to use?
All of our products are rigorously tested to ensure they meet safety requirements and standards. When using any abrasive material, always remember to follow best practices for personal protective equipment (PPE), including eye protection and respirators if necessary.
The 3M™ Cartridge Roll 747D is a powerful sanding tool that is perfect for stock removal. Its surface is covered with blended ceramic materials that enhance 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. This 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. The semi-flexible x-weight backing and sturdy design 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, making them great for deburring, blending, and polishing in hard-to-reach areas.
Multi-layered AbrasiveThe 3M™ Cartridge Roll 747D has a multi-layer design 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.
