HTC grinding shoes featuring three rhombus segments are high-performance tools designed for the HTC EZ Change system. By using three segments instead of one or two large ones, these shoes increase the number of “leading edges,” which allows for a more aggressive cut while maintaining a smooth finish.
Diamond segments have many different kinds of shape: Arrow, Rhomboid, Rectangle, Curved Rectangle, Coffin, Oval, Button, etc. Rounded shape is ideal for achieving a smooth finish and minimizing deep scratching, particularly on uneven floors.
Full round PCDs are very aggressive; The diamond tool has one half-round PCD segment. split (1/2) PCDs are slightly less aggressive but still excellent for heavy removal. Diamond grinding shoe or plate used for concrete floor preparation. Specifically, this tool used to remove heavy coatings like epoxy, glue, or paint.
Huanlong 2 round segments Lavina grinding shoesare specifically designed for high-efficiency floor prep and aggressive coating removal.
Redi-Lock with 3 Half PCDs and One Button is a specialized, high-performance configuration designed for the rapid removal of coatings (up to 3mm thick) while maintaining an extremely high level of stability.

Redilock PCD the “3×1/2” signifies three segments, each half-round, designed for efficient coating removal, often paired with a diamond bar for stability, and comes in clockwise or counter-clockwise directions for different grinder head rotations.
Key Features & Function
Three half-PCDs allow the shoe to find a stable footing on the slab. This significantly reduces “machine chatter” and the tendency for the grinder to hop or vibrate when it hits thick patches of epoxy.
Having three separate leading edges means the tool is constantly “biting” into the coating. It excels at shredding brittle materials like thick epoxy, self-leveling underlayment, and pool deck coatings.
The pressure from the machine is distributed across three points rather than concentrated on one, which can actually extend the life of the PCD segments compared to a single-segment shoe.
Wet vs. Dry: While these can be used wet to keep the floor cool, they are highly effective dry, which prevents the coating from turning into a sticky “slurry” that can be difficult to clean up.
Direction is crucial: Always match the tool’s rotation (CW/CCW) with your machine’s head rotation for safety and effectiveness.
