Cup Wheels

Concrete & Stone Cup Wheels

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 patterns, bonds, sizes, mounts, and grits, so you can match the wheel to your material, your machine, and your finish. Call and talk to a real surface-prep expert, not a call center.

Which Cup Wheel Do You Need?

We carry a full range of diamond cup wheels — matched to different materials, jobs, sizes, mounts, and finishes. Here's how to find the right one for your machine and your work:

Metal Dot Cup Wheels — Aggressive Concrete Grinding

Metal-bond diamond dot wheels, differentiated by dot pattern:

• Metal Dot "Swirl" — dots in a swirl pattern; 4″, 5″, 7″
• Metal Dot "Double Row" — dots in two rows
• Metal Dot "Multi-Row" — dots in multiple rows

Segment & Turbo Cup Wheels — Aggressive Grinding

• Double Row Cup Wheel — two rows of diamond segments, 5/8″-11 thread; 5″ (30 grit), 7″ (16 & 30 grit)
• Arrow Cup Wheel — arrow-pattern segments; 5″ & 7″, 30 grit
• STI Diamond Turbo Cup Wheels — swept turbo segments, quick-change mount for fast swaps
• Turbo Cup Wheel — swept turbo segments, velcro-backed

7″ Turbo Family — Smoother Grinding & More Coverage

• 7″ 12-Segment Soft Bond — long-segment soft bond for harder concrete
• 7″ 12-Segment 30/40 Grit — built for coating removal
• 7″ 24-Segment Turbo — denser segments for a smoother result
• 7″ 24-Segment Premium Turbo — premium 24-segment wheel

For Coating & Adhesive Removal

• PCD Cup Wheel — the go-to for epoxy, urethane, carpet glue, mastic, paint, and rubbery coatings. PCD shears off gummy material that clogs and loads up a standard diamond wheel.

For a Fine Finish / Edge Work

• Ceramic Edge Cup Wheel — aggressive grind with a superb, gouge-free finish; grits #30–#400
• 7″ 18-Segment Bi-Turbo (120/140 Grit) — the fine metal step before resin polishing (great on the TC-7 edger)

Specialty Cup Wheels

• Velcro-Back Turbo — 3″, mounts on a backer for fast, tool-free grit changes
• 4″ Flexible Metal Bond — rubber backer reduces vibration for smoother grinding
• Wood Floor Cup Wheel — vacuum-brazed, for wood floor work; 5″ & 7″

Metal Dot Cup Wheels

Metal-bond diamond dot wheels for aggressive grinding and long life — in three patterns:

• Metal Dot Swirl — swirl dot pattern
• Metal Dot Double Row — double row dot pattern
• Metal Dot Multi-Row — multi-row pattern; favored for stone fabrication and fiberglass mesh removal

Turbo Cup Wheels

Swept, spiral-segment wheels for fast, aggressive grinding with efficient debris clearing:

• 5″ Turbo Cup Wheel — swept spiral segments, 5/8″ open hole
• 7″ 12-Segment Turbo Cup Wheel — Soft Bond — long-segment soft bond for harder concrete
• 7″ 12-Segment Cup Wheel — 30/40 Grit — for coating removal
• 7″ 24-Segment Turbo Cup Wheel — denser segments for smoother, efficient grinding
• 7″ 24-Segment Premium Turbo Cup Wheel — premium 24-segment wheel

Ceramic Edge Cup Wheels

Aggressive grinding with a superb finish — for edge work where appearance matters:

• Ceramic Edge Cup Wheel — blends into the floor, eliminates gouging, a beautiful edge in fewer steps; 5″ & 7″, grits #30–#400
