PCD tooling is what contractors reach for when a coating will not come off with conventional diamond segments. PCD stands for polycrystalline diamond, and instead of abrading the floor it shears hard, stubborn material away from the concrete underneath. EDCO lists this Magna-Trap Dyma-PCD accessory as ideal for heavy removal of hard coatings and waterproofing membrane. It is aggressive by design, and EDCO is direct about the trade off: it leaves a rough surface texture and can potentially create heavy scratch marks on concrete. Use it to get a stubborn coating off, then follow with finer tooling to bring the profile back.
Left hand versus right hand
This is directional tooling, which is why EDCO catalogs it in left hand and right hand versions. The rule from EDCO is not symmetrical, so it is worth reading carefully:
- Left hand tooling is used on both single disc and dual disc grinders
- Right hand tooling is for dual disc grinders only
This listing is the left hand version, which makes it the one that covers single disc machines. A dual disc grinder needs both left and right hand tooling to be fully outfitted.
Fits
- EDCO Magna-Trap floor grinders, single disc and dual disc models
- EDCO Magna-Trap turbo grinders, 7 inch, 9 inch and 10 inch models
- Classic style grinders that have been retrofitted with the Magna-Trap multi-tooling disc
Single disc EDCO grinders take left hand tooling only. Dual disc grinders take both hands. Confirm your grinder model and disc configuration before ordering.
Aggressiveness
EDCO also catalogs a Dyma-PCD with a backing segment, which is the less aggressive option. The backing segment prevents the PCD from digging or gouging deep into the concrete, at the cost of a slower removal rate on thicker coatings. If you are working thin coatings over a floor you need to keep smooth, that version is worth a look instead. Concrete surface profile from PCD tooling varies with the application and the coating being removed.
