Best in Class Performance in Every Grade
Part of our full line of 3M™ Blue Abrasives, the 3M™ Hookit™ Blue Abrasive Disc is engineered for best in class cut, life and efficiency across your entire shop. The disc features a tough ceramic blended with premium aluminum oxide mineral for just the right balance. 3M™ Blue Abrasives deliver consistently excellent results in a minimum amount of time, on jobs ranging from aggressive paint removal and fresh filler sanding to blend preparation and sanding primer. Discs are available in a wide range of sizes and grades.
Dust Extraction Features Enhance Performance and Disc Life
The multi hole pattern on this disc is specially designed to capture dust and keep it away from the abrasive surface. This specially designed hole pattern reduces loading and extracts dust more efficiently compared to standard 6 or 7 hole disc configurations. It includes alignment guides across the disc, making it fast and easy to align with nearly any backup pad. The mineral blend on the 3M™ Hookit™ Blue Abrasive Disc is bonded using upgraded resins for enhanced durability. An anti loading coating helps keep dust from gathering between the abrasive grains for a faster cut and for consistent performance throughout the life of the disc.
Our Hookit™ Attachment System
The Hookit™ attachment system has a hook and loop feature which makes disc attachment, removal, and re attachment clean and easy. It also facilitates use and re use of the disc for maximum product life. Hookit™ discs have a brushed nylon loop backing of the type most commonly used in everyday hook and loop applications. 3M™ Hookit™ disc pads (sold separately) feature hooks which grip the brushed nylon loop backing. It’s simple: just attach the disc and start sanding. The disc removes just as cleanly and easily. The Hookit™ system is designed for work spaces and applications where adhesive backed discs may become contaminated by dust, dirt, or debris.
