Supreme Standard PCD Scraper Cup Wheel | Non-Loading Coating Removal | 4" - 7"

The Precision Scraper for Sensitive Substrates "The primary failure in coating removal is 'Galling'—where high-speed friction melts sticky glue into the tool. At Supreme Diamond Tools, we engineered our Standard PCD Series to act as a precision scraper. Unlike our aggressive 'Studded Aggressor' wheels that shatter concrete, these 1/4 PCD chips are designed to slice and shave away coatings with 'cold-cutting' action. This prevents smearing and protects the concrete substrate from unnecessary damage, providing the perfect profile for thin-set reapplications." — The Supreme Diamond Engineering Team The Supreme Professional Standard PCD Cup Wheel is the contractor's first choice for removing "gummy" or "sticky" materials. Featuring high-grade 1/4 PCD (Polycrystalline Diamond) chips, this wheel slices through epoxy, polyurethane, and adhesives rather than grinding them, ensuring your machine stays productive without the frustration of tool clogging. 🚀 Why the Standard PCD Scraper is Essential 1/4 PCD Slicing Technology: Each segment features a razor-sharp 1/4 PCD chip that 'shaves' the coating off the floor. This cold-cutting method is the only way to effectively remove thick adhesives and mastic without melting them into a smeary mess. Zero-Loading Performance: Because PCD doesn't rely on a metal bond matrix to hold the diamonds, it never "loads up." The large chip surface remains exposed and sharp through thousands of square feet of coating removal. Substrate Protection: Engineered to focus the energy on the coating rather than the concrete. It leaves a cleaner, more uniform profile (CSP 3-4) compared to aggressive studded wheels, making it ideal for jobs where the floor must remain relatively level. Durable Brazed Design: Our PCD chips are brazed to a high-strength steel body using an industrial-grade process that ensures the segments remain secure even under the high-torque demands of floor prep machines. Universal Versatility: Fits all major professional angle grinders and floor grinders with standard 5/8"-11 or 22.23mm arbors. ⚖️ Selection Guide: Which PCD Tool fits your job?

If your cut path strikes a metal screw, bolt, or concrete anchor, it can fracture the PCD chip. Always sweep the floor for protruding metal before starting. If you must remove coating over metal, slow your RPM and use a light touch to preserve the shaving edge. 🏗 Optimized Material Applications Sticky Glue Removal | Gummy Mastics | Thin-Build Epoxy Coatings | Polyurethane Stripping | Paint Removal from Substrates | Waterproofing Membrane Removal 📦 Global Infrastructure & Flooring Supply: Supreme Diamond Tools provides specialized surface prep tools with high-efficiency logistics from our Tianjin and Zhejiang manufacturing centers.
