Standard Trap Base Plate with 2 Half PCD is a specialized heavy-duty grinding tool used primarily for the removal of thick, stubborn floor coatings. In the concrete surfacing industry. Trapezoid shape of the metal base plate, which is designed to fit into the quick-change or bolt-on systems of most floor grinding machines.
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.
The segments of this grinding disc are profiled segments. Concrete grinding wheel is used on floor grinder, professionally used for grinding different hardness of concrete and masonry materials, removing hard epoxies, urethane, and other coatings or toppings. We can supply other types of grinding disc. The quality level is premium.
Trapezoid grinding disc have two segments per shoe increases the surface area contact. This results in a smoother finish and prevents dig into the concrete floor.
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.
