Huanlong Crossover Segment Turbo diamond grinding cup wheel, For fast and aggresive grinding hard material such as concrete, Terrazzo, Engineered Stone, granit, marble and etc.

Fast removal of thick coating such as old glue, epoxy, paint, in particular thick resins.
Creates slip-resistant finish on granite and marble, breaks down coatings prepares surface for application of new coating overlay, enhances the combination of floor and new layer material.

It can perform various tasks, including surface leveling, removal of old coatings (such as paint or epoxy resin), and coarse grinding before floor polishing.

Werkmaster T-shaped Diamond grinding segment is mainly used in conjunction with floor grinding machines to perform rough grinding, polishing of concrete or terrazzo floors, as well as removal of old coatings (such as paint, glue or epoxy resin)
The Redi-Lock with 1/2 PCD and 2 Arrow Segments is an elite heavy-duty removal tool. It combines the raw scraping power of a half-round PCD with the precision “slicing” of arrow-shaped diamond segments. This is a specialized configuration typically used when you need to strip a thick, stubborn coating and prep the concrete for a new high-build system in a single pass.

Trapezoid Half PCD w/ Double Arrow Coating Removal PCD Diamond Grinding Segment Concrete Tools
1. The Power of the “Arrow” Design
Unlike standard rectangular bars, Arrow Segments have sharp, pointed leading edges.
Slicing Action: While a standard bar grinds, the arrow “slices” into the coating residue. This is particularly effective for sticky adhesives (mastic, glue) that might otherwise smear under a flat bar.
Reduced Friction: The tapered shape allows the segment to penetrate the surface more easily, providing a more aggressive bite into the concrete substrate.
2. Why the “1/2 PCD + 2 Arrow” Combo?
This setup is designed for heavy-duty production:
Maximum Shredding: The 1/2 PCD chip acts as the primary “shredder,” tearing through thick epoxy, urethane, or waterproof membranes.
Double Stability: Two arrow segments provide a wider footprint than a single bar. This keeps the grinding head perfectly level, preventing the machine from “walking” or vibrating excessively when hitting uneven patches.
Integrated Surface Prep: The two arrow segments are usually a very coarse grit (roughly 16–25 grit). As the PCD removes the coating, the arrows immediately begin grinding the concrete, leaving a high-profile surface that is ideal for bonding new materials.
