The EDCO QC-PCD1-LB is a Magna-Trap PCD (polycrystalline diamond) tool with a backing segment, built for medium-aggressive removal of coatings and waterproofing membranes from concrete. Surface-prep contractors mount these left-hand, blue segments on EDCO single- or dual-disc grinders to strip stubborn material without gouging the slab.
Where it is used
The PCD design shears coatings off while the backing segment controls depth, making it a fit for:
- Medium removal of epoxy, paint, and thin coatings from concrete
- Stripping waterproofing membranes and mastics ahead of a new floor system
- Left-hand rotation positions on EDCO single-disc and dual-disc grinders
- Jobs where a controlled, medium-texture profile is needed before recoating

Frequently asked questions
What does the backing segment do?
The backing segment rides alongside the PCD and prevents it from digging or gouging deep into the concrete, so you get controlled, medium removal and a consistent texture.
When should I use a PCD instead of a diamond segment?
PCDs excel at shearing off soft, gummy, or thick coatings and membranes that would load up a standard diamond. This medium-aggressive PCD is a good choice for coating and membrane removal.
Why left-hand and how many are in a pack?
Left-hand segments are positioned for the correct rotation on your grinder head. This part is sold as one pack of three segments; confirm you need the left-hand (LB) version for your machine setup.
Will this slow down on thicker coatings?
Yes. On thicker coatings the removal rate slows, which is normal for a medium-aggressive PCD. For very heavy buildup a more aggressive tool may remove material faster.
