Diamond cup wheels turn a hand grinder into a powerful grinding and prep tool — cutting through coatings, high spots, thinset, and surface material fast. We carry a full range of cup wheels in different diamond patterns, bonds, sizes, and grits, so you can match the wheel to your material, your machine, and your finish. From aggressive concrete prep to a refined edge to stone fabrication and wood floor work, there's a wheel for the job. Call and talk to a real surface-prep expert, not a call center.
Metal Dot Cup Wheels
Metal-bond diamond dot wheels for aggressive grinding and long life — in three patterns:
Harder concrete → 7″ 12-Segment Soft Bond (softer bond exposes fresh diamond on hard concrete)
Smoother, efficient grinding on larger areas → 24-Segment Turbo (Standard or Premium)
Stone fabrication / mesh backing removal → Metal Dot Multi-Row
A clean, finished edge → Ceramic Edge
Wood floors → Wood Floor Cup Wheel
Size → 4″ and 5″ for tighter/detail work, 7″ for covering more area
Grit → coarser (16–30) for aggressive removal, finer (up to #400 on the Ceramic Edge) for a refined finish
Not sure which combination fits your grinder and your job? That’s exactly what we’re here for — call and we’ll match you to the right wheel.
What Cup Wheels Are For
Removing coatings, paint, mastic, and thinset
Grinding down high spots and leveling
Surface preparation before coating or overlay
Stone fabrication — grinding granite, quartz, and engineered stone; removing mesh backing
Wood floor grinding and prep
Edge and detail grinding with a clean finish
Grind Safely
Grinding concrete releases harmful silica dust. Always pair your cup wheel with a dust shroud and a dust collector to capture the dust at the source and stay OSHA-compliant.
