Quick Overview
  • For use with our 20" refinisher
  • Set of 3 concrete scrapers
*Due to the fact that this is a special order item, all sales are final and no returns will be accepted.*


You can remove years of wear from a concrete surface with the OnFloor 20" concrete resurfacing machine, and these diamond cobalt attachments. They will scrape, or abrade, your concrete with a deeply embedded, course diamond grit, that will quickly ready your floor for any new coating application. If your concrete floor has a coating that doesn't require removal, these attachments will abrade the surface to remove any gloss. We then also have a concrete scarifying tool that levels concrete and removes coatings.

These diamond cobalt attachments are available in 6 different sets. Gray is 6 grit, pink is 12 grit, red is 20/30 grit, green is 50/60 grit, white is 80/100 grit, and black is 100/120 grit. The red cobalt diamond attachments are definitely our best sellers, due to their versatility. Obviously when starting with a heavily damaged concrete floor, you'll need to start with lower grit attachments for a stronger abrasion, then slowly move to higher grit attachments, to smooth floor out. Estimated coverage is 8,000 square feet per set of 3 scrapers.
