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.
Huanlong 7″ 12 sgement Turbo Diamond grinding cup wheel, For fast and smooth grinding material such as concrete, Terrazzo, Engineered Stone, granit, marble and etc.
The M16 thread 180mm Hybrid 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.
Huanlong 7 inch Satellite Low profile diamond grinding cup wheel, For fast and aggresive grinding hard material such as concrete, Terrazzo, Engineered Stone, granit, marble and etc.
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.
