Overview

This 7” ceramic cup wheel is built for concrete edge grinding when you want more coverage and better scratch control than aggressive metal wheels. It’s a “bridge” tool—cleaning up scratches and helping resin pads run faster and more evenly.

Best for

• Concrete edge grinding and corner blending

• Scratch cleanup after metal grinding

• Transitional step before resin polishing (especially on medium–hard slabs)

Features

• Ceramic bond for controlled cut + cleaner scratch pattern

• Larger 7” diameter for faster coverage on edges

• Works dry or wet (dry with dust control is most common)

Fitment

• For standard edge grinders / angle grinders

• Common thread options: 5/8”-11 or M14 (match your spindle)

FAQ

Q: When should I pick 7” vs 5”?

A: 7” covers more area faster; 5” is easier in tight corners and detail work.

Q: Is this for heavy coating removal?

A: No—use PCD for coating removal. This is for grinding/transition and scratch control.

Q: Dry or wet?

A: Both. Dry is common for edge work—use a vacuum/shroud if possible.
