3M Cubitron II Hookit Cloth Disc 900DZ features ceramic 3M Precision-Shaped Grain, a revolutionary advancement in abrasive technology. The triangular shaped ceramic mineral is designed to slice through the substrate, rather than gouging or plowing like conventional abrasives, resulting in a disc that cuts up to 2x faster than conventional abrasives. The J-weight cloth backing delivers outstanding tear resistance, durability and a consistent, uniform finish on a variety of substrates.

  • COVERS A WIDE RANGE OF APPLICATIONS: Versatile disc handles applications from finishing and sanding to grinding and de-flashing
  • VERSATILE PERFORMANCE: Disc performs well on aluminum, fiberglass, gelcoat, hard and soft woods
  • QUICK AND EASY DISC CHANGES: 3M™ Hookit™ attachment system allows for easy disc changes and helps optimize disc life
  • OPEN COAT CONSTRUCTION: Open coat construction and load-resistant coating prevent clogging to optimize cut throughout the life of the disc
  • HIGH-PERFORMANCE CERAMIC GRAIN: Ceramic mineral delivers excellent performance on a wide range of substrates
  • LIGHTWEIGHT CLOTH BACKING: J-weight cloth backing combines wear resistance with flexibility

Exceptionally Hard and Strong Abrasive Grain

3M Cubitron II Hookit Cloth Disc 900DZ is a high-performance abrasive disc designed for various applications such as metal fabrication, woodworking, paint prep, and composite work. It offers fast and efficient stock removal, making it one of the best choices among 3M discs.

The disc features 3M Precision-Shaped Grain, which surpasses the cutting capabilities of both aluminum oxide and silicon carbide minerals. This exceptional grain provides superior cut-rate and durability, ensuring optimal performance and longevity.

Resists Accumulation of Sawdust and Sanding Debris

The open coat construction of the 3M Cubitron II Hookit Cloth Disc 900DZ prevents the accumulation of sawdust and other sanding debris. This unique design allows the cutting edge of the grain to continue cutting efficiently by self-fracturing and exposing fresh cutting edges. As a result, the disc maintains its effectiveness throughout the sanding process.

Neutralizes Swarf for Fast Cutting

To enhance performance, this disc is treated with an anti-static treatment that neutralizes the electrical charge generated during sanding, especially on wood surfaces. By neutralizing the charge, the disc prevents static-charged swarf from clinging to the disc, workpiece, and machinery. This helps to maintain a clean working environment and ensures fast and efficient cutting.

In addition, the open coat abrasive of the 3M Cubitron II Hookit Cloth Disc 900DZ minimizes loading issues caused by dust. Whether it's coarse or fine, powdery dust can degrade performance and productivity. With this disc, loading issues are minimized, allowing for consistent and fast cutting.

Fast and Easy Disc Changes

The 3M Hookit attachment system offers a simple, swift, and secure method for changing discs. The soft side of the disc is covered with loops, while the rougher mate has J-shaped hooks. When pressed together, the loops and hooks cling securely, even in rugged applications. When it's time to change the disc, they separate cleanly and easily. Additionally, 3M Hookit discs can be re-used for the extent of their abrasive life, providing convenience and cost savings.
