The EDCO QCPK-MC-0030-L is a 3-pack of left-hand Dyma-Peak diamond tooling for EDCO Magna-Trap floor grinders, in the medium-concrete (grey) bond with a 30-grit-class diamond. Dyma-Peaks are directional pyramid-point segments built to grind and remove aggressively - mastic, thinset, coatings, and high spots - while leaving far less gouging than traditional scarifying, with a finished profile in the CSP 1-2 range that is ready for most coatings.
Use Cases
Concrete prep contractors run Dyma-Peaks to strip glue and thinset ahead of epoxy or polished-concrete work. Because the peaks come to a sharp point, they start slightly less aggressive when brand new and bite harder as the point opens up - useful to know when estimating the first few passes. Left-hand tooling is the required rotation for EDCO single-disc grinders (SEC-NG, TG-10, and TMC-7), and dual-disc Magna-Trap machines take one left-hand set alongside a right-hand set (QCPK-MC-0030-R) so both discs cut with the rotation.

Frequently Asked Questions
What is the difference between left-hand and right-hand Dyma-Peaks?
The segments are directional - the diamond peaks are angled to cut with the disc rotation. EDCO single-disc grinders (SEC-NG, TG-10, TMC-7) take left-hand tooling only; dual-disc machines take a left-hand set on one disc and a right-hand set (QCPK-MC-0030-R) on the other.
What surfaces are medium-bond Dyma-Peaks best for?
The grey medium-concrete bond suits average-hardness concrete for removing mastic, thinset, coatings, and surface irregularities. It leaves a CSP 1-2 profile suitable for most epoxy and coating systems.
Why do new Dyma-Peaks seem to cut slowly at first?
Each peak comes to a sharp point with little diamond surface area exposed. The tooling gets more aggressive after the first passes open the points up - factor that into the first section you grind.
How many pieces do I need for my grinder?
Each QCPK-MC-0030-L is a complete 3-piece set for one disc. Single-disc grinders need one pack; dual-disc grinders need one left-hand pack and one right-hand pack.
