The bottom line: these hook and loop backed pucks are designed to remove scratches left by metal bond grinding discs and leave a consistent scratch pattern, making them a practical choice for contractors preparing slabs for resin polishing. The reviewer found the aggressive copper and diamond mix durable and well suited to follow metal bond stages before moving to finer polishing tools.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCopper and diamond bond:\u003c\/strong\u003e The blend of professional-grade diamond powder and copper powder creates aggressive segments that remove metal bond scratches effectively.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransitional stage use:\u003c\/strong\u003e Designed to be used after metal bond grinding discs and before resin polishing tools to provide a consistent scratch pattern for densifying.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHook and loop backing:\u003c\/strong\u003e The 3 in diameter discs are easy to attach and remove from universal ride-on and walk-behind grinders, saving time on the job.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurability:\u003c\/strong\u003e The copper bond and diamond mix provides long using life compared with soft polishing pads when tackling coarse scratch removal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal match:\u003c\/strong\u003e Compatible with common floor grinders such as Sase, Diamatic, Lavina, Husqvarna, WolfPack and Edco, making them versatile for rental fleet or contractor kits.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe ComeFloor 3 in 100# copper pucks suit concrete contractors, flooring specialists, and rental operators who need a robust transitional tool to bridge metal bond grinding and resin polishing.
