Rhombus diamond grinding segments are durable, high-efficiency abrasive tools primarily used for concrete floor grinding, polishing, and surface preparation. Their unique shape provides a larger surface area and aggressive grinding action compared to other segment types

It is used to connect different brands or types of diamond grinding blocks/shoes to Klindex brand floor grinders. This enables contractors to use various tools without having to purchase a complete set of specialized tools for each different brand of machine.

The 180mm 1/2 PCD diamond grinding cup wheel is designed for fast removing hard and tacky surface coating including urethane epoxy, paint, glue, ,waterproofing membrane,pool deck coating, thick mastic,VCT mastic, black tar adhesive, old and new epoxy coating, as well as thick rubber materials on the concrete floor.
Redi-Lock with 2 Square PCD refers to a specific type of floor grinding tool designed for the Husqvarna Redi-Lock quick-change system. These tools are high-performance “scrapers” used primarily for the aggressive removal of tough floor coatings rather than standard concrete grinding.

PCD segments Instead of “grinding” the surface down like sandpaper, PCDs “rip and strip” the material. This removal tools do not heat up or smear sticky coatings, making them much faster for thick removals.
Two square PCD segments on a single Redi-Lock shoe provides a balance between aggression and stability. Square-shaped segments have a long leading edge. This makes them particularly effective on uneven concrete surfaces compared to round PCDs, as they are less likely to “dive” too deeply into low spots while still maintaining a sharp scraping edge. Using two segments (rather than one) increases the tool’s life and helps stabilize the grinding head, especially on heavier three-phase planetary grinders.
Double Square PCD is the “heavy hitter” for surface preparation. It is used to remove:
Thick Coatings: Epoxies, urethanes, and polyaspartics.
Stubborn Residues: Black mastic, carpet glue, and tile adhesive.
Waterproofing Membranes: Thick rubberized layers that would gum up standard diamond segments.
PCD tools are often directional. You must ensure you have “Right” (clockwise) or “Left” (counter-clockwise) shoes depending on the rotation of your grinder’s heads.
