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
