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.
3×1/4 PCDs: Instead of one large scraper, you have three smaller contact points. This creates more “shaving” actions per rotation, which is more effective at removing brittle or flaky coatings without causing the machine to jump or vibrate.
The 1-Bar Segment: This is a diamond-infused metal bar that acts as a depth gauge and stabilizer. It prevents the PCD chips from digging too deeply into the concrete, ensuring you only remove the coating and a tiny fraction of the substrate.
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.
