The EDCO Magna-Trap Dyma-PCD Left-Hand (LH) #QC-PCD1-L is a directional polycrystalline diamond (PCD) tooling segment built for extremely aggressive removal of industrial-strength floor coverings. Concrete restoration contractors, flooring installers, and surface prep crews mount this left-hand tooling on EDCO Magna-Trap floor grinders to dig through thick epoxies, waterproofing membranes, and other hard coatings that standard diamond cup wheels can't touch. It leaves a rough, textured concrete surface, ready for the next step in a coating-removal or surface-prep job.
Use Cases
- Heavy epoxy and coating removal - strips thick epoxy, polyurea, and other industrial-strength floor coatings down toward bare concrete in fewer passes than standard diamond tooling.
- Waterproofing membrane removal - digs through built-up waterproofing membranes and sealers that resist standard grinding segments.
- Mastic and adhesive removal - cuts through old carpet mastic, tile adhesive, and glue residue ahead of a flooring tear-out.
- Surface prep before new flooring installation - opens an aggressive mechanical profile for epoxy, coatings, or polished concrete systems to bond to.
- Older grinder retrofits - fits Classic-style EDCO grinders retrofitted with the Magna-Trap Multi-Tooling Disc, extending PCD removal capability to existing grinder fleets.
Specifications
- Concrete Surface Profile (CSP) Rating: Varies depending on application
- Tooling Classification: Directional
- Handing: Left-Hand (LH) - for use on Single & Dual-Disc Grinders
- For Use On: Magna-Trap floor grinders (single or dual-disc models); Magna-Trap Turbo Grinders 7-inch/9-inch/10-inch models;Classic-style grinders retrofitted with Magna-Trap Multi-Tooling Disc
- Surface Result: Leaves a rough, textured surface profile and can create heavy scratch marks on concrete
Because this tooling is built for maximum removal speed, most contractors run it as the first, most aggressive pass on a coating tear-out, then follow with a finer-grit metal-bond diamond pass to knock down the scratch pattern and flatten the profile before coating, polishing, or installing new flooring.
Frequently asked questions
What's the difference between left-hand (LH) and right-hand (RH) Dyma-PCD tooling?
Handing refers to the direction a directional (non-reversible) PCD segment is built to cut. Single-disc EDCO Magna-Trap grinders run left-hand tooling only. Dual-disc grinders need both left-hand and right-hand PCDs installed together so each disc cuts in the correct rotation. This listing, #QC-PCD1-L, is the left-hand segment; the matching right-hand segment is sold separately for dual-disc setups.
Which EDCO grinders is the QC-PCD1-L compatible with?
It fits Magna-Trap floor grinders in single- and dual-disc configurations, Magna-Trap Turbo Grinders in 7-inch, 9-inch, and 10-inch models, and Classic-style EDCO grinders retrofitted with the Magna-Trap Multi-Tooling Disc.
How aggressive is the cut compared to other PCD options?
This standard Dyma-PCD (without a backing segment) is EDCO's most aggressive PCD option, built to dig into thick epoxies, waterproofing membranes, and industrial coatings quickly. Contractors who need a more controlled cut for thinner coatings, glue residue, or coatings closer to grade typically step down to the Dyma-PCD with backing segment instead.
Does this tooling leave scratch marks on the concrete?
Yes. Since it's engineered for removal speed rather than a finished profile, it leaves a rough, textured surface and can create heavy scratch marks. Most crews plan on a follow-up finer-grit diamond pass to refine the surface before coating or polishing.
How many segments come in a pack, and do I need a matched set?
#QC-PCD1-L ships as a 3-pack of left-hand segments. A single-disc grinder only needs left-hand tooling. A dual-disc grinder needs a matched set of left-hand and right-hand segments across both discs for balanced, correct-direction cutting.
Discount Cleaning Products stocks genuine EDCO Magna-Trap tooling for contractors who need job-ready diamond tooling without chasing down multiple suppliers. The QC-PCD1-L left-hand Dyma-PCD is built to the same directional PCD spec used across the Magna-Trap grinder line, so it drops straight into an existing tooling setup.
