5", 6" & 8" Discs 80 - 36 Grits
Although they are switching the Purple line over to the better performing Hookit Clean Sanding format, 3M still offers the original Stikit no-hole Purple discs in the coarse grits below.
Purple abrasives are 3Ms 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.
3M's fastest cutting, longest lasting abrasive save on labor and material costs, with excellent results
Stikit adhesive backing makes changing discs easy
All these discs have a stearate coating to prevent loading and provide a consistent finish
Resin bonded for heat resistance
Excellent for use on tough marine gelcoat, paint and primer systems
Also use for shaping and sctratch refinement on fiberglass, fillers and putties, metals, and plastics
Constructed of a unique blend of aluminum oxides and an incredibly durable man-made ceramic mineral, Cubitron, for longer disc life
Priced by the box
As noted, 3M is switching the Purple line over to Clean Sanding discs on a Hookit backing.
Even in non-vacuum applications, the Clean Sanding Discs perform better and last longer
