Sharp Abrasive for a Refined Finish
With its open coat construction and aluminum oxide mineral abrasive, our 3M™ Hookit™ Gold Disc 216U provides a sharp cut – more aggressive than a comparable closed coat abrasive of the same grade – without dust accumulating on the disc. And its fine grades from P220 to P800 along with light A-weight paper backing make it ideal for feather-edging, as a final step before priming or for primer sanding. The Hookit™ Gold Disc 216U is available in 3-, 5- or 6-inch diameter sizes for substrates including clear coat, fiberglass, paint, primer and plastic.
Resists Dust and Debris
Open coat construction means the abrasive grains on our 3M™ Hookit™ Gold Disc 216U are placed with space between them to help evacuate sanding dust and other debris to avoid clogging the cutting edge of the grains. The load-resistant coating on the abrasive grains also allows the disc to continue cutting even when sanding paints and other materials that would otherwise clog the disc and hinder sanding ability. All of this adds up to increased productivity and reduced material consumption.
The 6-hole pattern on select versions of 3M™ Hookit™ Gold Disc 216U facilitates dust evacuation, keeping it off of the disc and the workpiece for longer disc life and a more consistent finish. This design doesn’t even require alignment of holes with the disc pad, making disc changes quick and simple.
Our Hookit™ Attachment System
3M offers a complete line of hook-and-loop style Hookit™ discs for work spaces where adhesive backed discs may become contaminated by dust, dirt, or flying debris. They are often used in applications where a 3M™ Stikit™ disc may be too aggressive, as Hookit™ discs tend to leave finer finishes than adhesive backed discs. Hookit™ sanding discs conveniently and firmly attach to a hook-and-loop backup disc pad (sold separately) on a random orbital sander, can be removed cleanly and easily, and can be re-used again and again for the extent of the abrasive life.
Aggressive, Yet Smooth
Through a combination of science, strength and smoothness – from the grain to the back-up disc pad attachment – our 3M™ Hookit™ Gold Disc 216U delivers a sharp, aggressive cut that leaves a consistent, uniform finish for professional auto body projects.
