Diablo StickFast 5 in. Ceramic Blend Adhesive Sanding Disc 40 Grit Ultra Coarse — 5 Pack is built for aggressive material removal with lasting performance on tough jobs. Designed for 5-inch power sanders, these stick-on discs deliver fast stock removal without excessive heat buildup, so you can work longer between changes and finish stronger.
Why this disc stands out:
-
Ultra coarse 40 grit provides the fastest removal for weld blending, rust and mill-scale removal, deburring, and shaping rough surfaces.
-
Ceramic blend abrasive delivers exceptional durability and cooler cutting compared with standard grits, meaning fewer disc changes and less glazing during demanding tasks.
-
Adhesive (stick-on) backing snaps securely to standard 5" backing pads, enabling quick disc changes and consistent contact with the workpiece.
-
Five discs per package give you reliable replacements on hand for extended projects, reducing downtime and transitions between tasks.
-
Versatile for metal and woodworking — ideal for prepping metal surfaces, deburring castings, smoothing rough wood, and priming surfaces for coatings.
Practical tips for best results:
- Keep the sander moving in smooth, overlapping passes to avoid gouging and to maximize disc life.
- Apply moderate, even pressure and let the ceramic blend grit do the work—don’t force the tool.
- Periodically check for loaded or glazed areas and replace the disc to maintain consistent cutting action.
- Pair with a dust-collection system or shop vac to minimize debris and extend disc life by preventing clogging.
Who should reach for these discs?

If you value speed, durability, and dependable stick-on convenience in a 5" format, the Diablo StickFast Ceramic Blend 40 Grit discs are a solid choice to power through your project with confidence.
