The Ease of a Disc Roll, The Speed of Stikit™ Attachment3M™ Stikit™ disc rolls are multiple adhesive-backed abrasive discs rolled onto a core. This makes them easy to tear off one at a time for speed and efficiency, and there's no need for liners which saves on material costs. These ready-to-use Stikit™ discs feature a pressure sensitive adhesive coating on the backs - simply press the disc onto the backup pad and you're ready to go. They remove just as cleanly, leaving an uncontaminated surface for the next disc. We recommend using Stikit™ discs with 3M™ Stikit™ Disc Pads.Sharp Abrasive for a Refined FinishWith its open coat construction and aluminum oxide mineral abrasive, our 3M™ Stikit™ Gold Disc Roll 216U provides a sharp cut - more aggressive than a comparable closed coat abrasive of the same grade. Light A-weight paper backing and a range of medium-coarse to fine grits make the disc ideal for featheredging and primer sanding. The Stikit™ Gold Disc Roll 216U is available in a range of sizes and works with all collision repair substrates including clear coat, fiberglass, paint, primer and plastic.Resists Dust and DebrisOpen coat construction means the abrasive grains on our 3M™ Stikit™ Gold Disc Roll 216U are placed with space between them to help evacuate sanding dust and other debris and avoid clogging the cutting edge of the grains. Theanti-loadingcoating also allows the disc to continue cutting even when sanding materials that would otherwise clog the disc. All of this adds up to increased productivity and reduced material consumption.Our 7-hole pattern on select versions of 3M™ Stikit™ Gold Disc Roll 216U helps clear dust from the surface of the disc, making for longer disc life and a more consistent finish.Better Science for Better Sanding from 3MOur 3M™ Stikit™ Gold Disc Roll 216U is designed for long life - even for tough auto body sanding projects. From its aluminum oxide mineral abrasive to its anti-loading open coat construction to its Stikit™ attachment, this disc roll is another way that 3M applies science to make life easier for professionals in collision repair.
