Huanlong 2 Round segments Redilock grinding shoes are specifically designed for high-efficiency floor prep and aggressive coating removal.

HTC double round grinding shoes are the go-to choice when you need a balance between aggressive material removal and a smooth, scratch-minimized finish. Because they have a rounded edge, they lack the sharp “leading edge” of a rectangular or arrow-shaped segment, which helps prevent deep gouging on uneven concrete.

HTC double bar grinding shoes are designed specifically for the HTC EZ Change system. The two rectangular diamond segments providing a balance between aggressive cutting and a stable, smooth finish.

Triangle grinding shoe is mainly used for grinding concrete floors and stone, and can also be used to remove paint, glue, epoxy resin and floor coatings.
PCD Trapezoidal Diamond Grinding Shoe (Shark-shaped, 2 Segment, 2 PCD) is a heavy-duty professional tool engineered for the aggressive removal of tough floor coatings. Unlike standard diamond shoes, which grind the surface, PCD (Polycrystalline Diamond) tools function as scrapers, peeling and slicing through materials.

The Sase M6 plate with 2×1/2 PCD & 2 Shark Segments for removing medium-thick coatings where you want to balance speed with a controlled finish.
Segment Type: 2 PCD + 2 Shark-shaped segments. The PCD bits do the heavy lifting of scraping, while the “shark” or bar segments (often made of metal-bond diamonds or tungsten carbide) stabilize the tool and prevent it from digging too deep into the concrete.
Base Shape: Trapezoid (Universal). This fits most standard floor grinding machines like Husqvarna, Lavina, and HTC using magnetic plates or quick-change systems.
Action: Aggressive scraping. Ideal for materials that would otherwise melt or “gum up” standard diamond segments.
This specific configuration is the industry standard for:
• Epoxy & Urethane Removal: Quickly strips thick coatings (over 1mm) without heat buildup.
• Adhesives & Mastics: Effective on stubborn carpet glue, black bitumen, and tile adhesives.
• Waterproofing Membranes: Peels back rubberized coatings that are too soft for traditional grinding.
• Paint & Varnish: Cleans old paint off concrete floors in a single pass.
Advantages of the “Shark” Shape
The shark-shaped segments serve two critical purposes:
1. Depth Control: They act as a “buffer,” preventing the sharp PCD tips from gouging the concrete slab too deeply.
2. Support: They help the machine run smoother, reducing the “chatter” (vibration) often associated with pure PCD tools.
