The efficient dust removal provided by these discs helps keep the abrasive surface cleaner for better sanding.
Furthermore, they last longer than the same discs without the holes, whether or not they are used with a vacuum!

In these discs 3M has combined its original dust-free hole pattern with the 300 Series Purple abrasive family for both dust extraction and superior abrasive performance.

• All these discs have a stearate coating to prevent loading and provide a consistent finish
• Resin bonded for heat resistance
• Surprisingly, tests show that this original hole pattern exhibits its best dust extraction when used with one of 3M's new Clean Sanding Backup Pads, rather than the original Dust Free pads that match this hole pattern.
• Priced by the box

• Heavy on the technical side....
Purple abrasives are 3M’s best performing class of abrasives.
Both more durable and faster cutting than other discs, they provide the greatest dollar value and the highest quality in abrasive minerals available.

Faster cutting increases productivity, while long-lasting abrasive particles reduce disc consumption — so shop techs spend less time changing sandpaper and more time sanding.
334U - light purple discs (finer grits) are constructed of a carefully graded, higher performance aluminum oxide mineral on a C-weight paper backing. (No Cubitron at the 300 level.)
