EDCO's Magna-Trap Double Dyma-Dots in 70-grit medium-concrete bond are the diamond tooling that lets a contractor strip coatings and grind concrete fast on an EDCO Magna-Trap grinder. This three-piece set is built for surface-prep pros, flooring installers, and restoration crews who need to remove epoxy, mastic, thinset, and waterproofing and leave a clean, level surface ready for the next coating.
The grey, medium-concrete bond is the general-purpose choice for typical concrete: aggressive enough to cut coatings and level minor imperfections, yet balanced so it wears predictably instead of glazing over. The double-dot design puts more diamond on the floor for faster material removal, while the magnetic Quick-Change mount snaps the tooling on and off the grinder head in seconds so a crew spends time grinding, not swapping parts.

Frequently asked questions
What does medium-concrete bond mean?
The grey, medium bond is matched to typical general-purpose concrete. Bond is chosen by concrete hardness: soft (yellow) bonds are used on hard or abrasive concrete, and harder bonds on softer concrete, so the diamond exposes at the right rate.
What will 70-grit Dyma-Dots remove?
They remove general-purpose epoxy, mastics, thinsets, waterproofing coatings, and more, and grind concrete to create a level surface with minimal scratching.
Why choose Double Dyma-Dots over single?
The double-dot configuration places more diamond segment on the floor, which speeds material removal on larger jobs compared with single dots.
Do these fit my EDCO grinder?
They use the EDCO Magna-Trap magnetic Quick-Change mount. Confirm your grinder is a Magna-Trap model that accepts QC2B tooling before ordering.
