Spiral Hole Pattern Helps You Get More from Each Disc 

To achieve maximum performance, the discs are designed with small spiral-patterned holes to give dust a better escape route, moving more dust away from your finishing surface without loading the disc. 

The spiral hole configuration allows for optimal particulate removal improving performance when used with or without a dust extraction system. When using dust extraction, hole alignment is not necessary to achieve direct air flow from the workpiece through the abrasive disc. Technicians can change these discs more quickly, saving time and promoting re-use, helping preserve abrasive life. In fact, 3M Hookit Purple Clean Sanding Abrasive Disc 334U can last 2 - 3 times longer than other discs – delivering professional results while improving the bottom line in collision repair. 

The Hookit Attachment System 

3M offers a complete line of hook-and-loop style Hookit discs for work spaces where adhesive backing may become contaminated by dust, dirt, or flying debris. Hookit discs conveniently and firmly attach to a hook-and-loop backup disc pad (sold separately). It’s simple: just attach the disc to the backup pad and start sanding. It removes just as easily and cleanly, and can be re-used again and again for the extent of the abrasive life. To ensure easy, fast attachment, the precise spiral multi-hole pattern of the 3M Hookit Purple Clean Sanding Abrasive Disc 334U does not require hole alignment with the back-up pad.
