Trapezoid PCD diamond grinding shoes 3*1/4PCD with 1 bar shaped
HuanLong Redilock PCD grinding shoes, it is manufactured with 3 PCD plus diamond bar. Maximum contact and usage of the diamond while working over rough surfaces. Trapezoid PCD is the great choice for removing thick coatings.
This tool of 3×1/4PCD with 1bar is the “insurance policy” for your concrete slab.
• Reduced Gouging: Unlike a “Naked PCD” (one with no bar), this tool won’t leave deep, swirling “trench” marks in the concrete. This is critical if you plan to polish the floor later.
• Consistency: The single bar ensures the head stays flat. It provides a light grind while the PCDs do the heavy lifting, cleaning up the residue in the same pass.
• High Performance on Thin-to-Medium Coatings: It is the ideal choice for epoxies, acrylics, and mastics that are under 3mm thick.
Coating Thickness: Thin to medium (under 3mm). Perfect for epoxies, glues, and urethanes.
Concrete Condition: Excellent for rain-damaged or “soft” concrete where you need to remove the top layer quickly.
Surface Finish: Leaves a coarse, ready-to-bond profile. Ideal if you are applying a new coating immediately after.
