3M Cubitron II Hookit Film Sheet 775L features 3M Precision Shaped Ceramic 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 an abrasive that cuts up to 2x as fast and lasts up to 6x as long as conventional abrasives.
Shop Talk: Built for Stock Removal
3M™ Cubitron™ II Hookit™ Film Sheet 775L is ideal for a broad range of applications focused primarily on stock removal, because the 3M Precision Shaped Ceramic Grain aggressively rids the workpiece of burrs. This sheet may be used on a wide variety of substrates, including metals, composites, gelcoat, and whitewood. For additional durability and edge retention, the film backing offers great tear resistance. Abrasive grain is adhered to the backing in an open-coat construction, which means the grains are spaced apart from each other. These spaces permit debris to escape, which can be especially helpful on work surfaces that tend to clog or load a coated abrasive.
Engineered to Help You Do More
3M precision-shaped grains have sharp peaks that easily "slice" through metal. They stay cool, cut fast and last long. Conventional ceramic abrasive grain tends to "plow" through the metal, causing heat to build up in the workpiece and the abrasive — resulting in a slower cut, shorter disc life and undesirable effects, such as brushing. We engineered this grain to deliver consistent results, part after part.
Combining Durability and Efficiency
3M™ Cubitron™ II Hookit™ Film Sheet 775L features a Hookit™ backing, which is a great match for work spaces where adhesive-backed abrasives may become contaminated by dust or dirt. Hookit™ abrasives can be removed cleanly and easily from the backup pad and can be re-used again and again for the extent of the abrasive life.
