Economical Features, Reliable Results
Part of a full range of economical abrasives, our 3Mâ„¢ Hookitâ„¢ Red Abrasive Disc 316U delivers dependable performance on a variety of collision repair substrates. The reattachable abrasive disc is ideal for fine featheredging and putty sanding, or choose a Red Abrasive Disc with D-weight paper backing for aggressive shaping of plastic filler or paint removal around damaged areas. Seven-hole construction on several versions of the 316U clears dust from the surface area and increases resistance to loading.
Aluminum Oxide Provides Performance and Savings
3M’s durable, reliable and economical abrasive saves material costs while delivering dependable results in collision repair. Aluminum oxide is popular among collision repair professionals because of its fast cut-rate and long life. This mineral is suitable for a wide variety of metalworking materials including ferrous alloys.
Our Hookitâ„¢ 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 on 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 flying debris.

The 3Mâ„¢ Hookitâ„¢ Red Abrasive Disc 316U carries our Red designation which indicates an economical option in an abrasive disc. From its abrasive to its adhesive-backed attachment, this disc delivers durability and reliability across your entire collision repair operation.
