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
Huanlong 2 Large rectangle segments Lavina grinding shoesare specifically designed for high-efficiency floor prep and aggressive coating removal.
Diamond grinding rings / segments used for polishing concrete floors, terrazzo, or stone. Floor Renovation Tools are typically used on floor grinders to grind and polish hard surfaces through diamond particles embedded in a metal bonding agent.
The sharp edged PCD crossover diamond grinding cup wheel is designed for super fast removing hard and tacky surface coating including urethane epoxy, paint, glue, pool deck coating, waterproofing membrane, 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.
