Discs are available in a wide range of sizes and grades. Dust Extraction and Anti-Loading Features Enhance Performance and Life The multi-hole pattern discs are 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.
