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 in terms of cut-rate and durability.

Improved Construction for Enhanced Performance

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 performance and provides consistent results throughout its lifespan.

Neutralize Swarf for Optimal Cutting Efficiency

To ensure optimal cutting efficiency, this disc is treated with an anti-static solution 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 not only improves the overall performance but also minimizes loading issues caused by dust, ensuring the disc cuts fast and efficiently.

Fast and Easy Disc Changes

The 3M Cubitron II Hookit Cloth Disc 900DZ features the innovative 3M Hookit attachment system, which allows for quick and secure disc changes. The disc has a soft side covered with loops, while its mate has J-shaped hooks. When pressed together, the loops and hooks cling to each other, providing a secure attachment 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 duration of their abrasive life, making them a cost-effective choice.
