• Runs wet or dry Threaded arbor that fits any variable-speed hand grinder (standard 5/8″-11 — confirm your grinder)
• 30 or 60 Grit Diamond segments last far longer than abrasive wheels and create less dust
• Pairs well with a dust shroud and vacuum for cleaner, OSHA-friendly grinding

How to Choose Your Cup Wheel

Diamond cup wheels come in different segment patterns and grits — a more aggressive pattern removes material fast for coating removal and leveling, while a finer one leaves a smoother surface for finish work.

Frequently Asked Questions

Can I use it wet and dry? Yes — it’s rated for both. Wet grinding controls dust and can extend wheel life; dry grinding is faster to set up (pair it with a dust shroud and vacuum).

Will it fit my grinder? It uses a threaded arbor that fits standard variable-speed hand grinders (most are 5/8″-11). Call us if you’re unsure.

What can it remove? Coatings, mastic, thinset, epoxy, paint, and high spots in the concrete itself.
