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

Experience fast and efficient stock removal with the 3M Cubitron II Hookit Cloth Disc 900DZ. This disc is perfect for metal fabrication, woodworking, paint prep, and composite applications. The 3M Precision-Shaped Grain used in this disc surpasses both aluminum oxide and silicon carbide mineral in terms of cut-rate and durability.

Resists Accumulation of Sawdust and Sanding Debris

The open coat construction of this disc prevents the accumulation of sawdust and other sanding debris. This ensures that the cutting edge of the grain remains sharp and efficient, as it self-fractures to expose fresh cutting edges.

Neutralize Swarf, Maintain Fast Cutting

An anti-static treatment is applied to this disc to neutralize the electrical charge generated during sanding, especially on wood. This helps prevent static charged swarf from clinging to the disc, workpiece, and machinery, which can degrade performance and productivity. Combined with the open coat abrasive, this disc minimizes loading issues, allowing the 3M Cubitron II Hookit Cloth Disc 900DZ to maintain fast cutting speed.

Fast and Easy Disc Changes

Changing discs is a breeze with the 3M Hookit attachment system. The soft side of the disc is covered with loops, while the rougher mate has J-shaped hooks. When pressed together, they securely cling even in rugged applications. When it's time to change the disc, they separate cleanly and easily. Plus, 3M Hookit discs can be re-used for the extent of their abrasive life, making them a cost-effective choice.
