The bottom line: these 3 in hook-and-loop diamond copper discs deliver an aggressive, consistent scratch pattern that makes them ideal for the stage between metal bond grinding and resin polishing. They stand out for durable copper-reinforced segments and a 50# grit that efficiently removes metal grinding marks while preparing concrete for further densifying and polishing.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiamond copper bond:\u003c\/strong\u003e The mix of diamond powder and copper powder provides aggressive cutting to remove scratches left by metal grinding discs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConsistent scratch pattern:\u003c\/strong\u003e Produces a uniform surface texture that speeds up subsequent densifying and resin polishing stages.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHook-and-loop backing:\u003c\/strong\u003e Easy to attach and remove on compatible grinders for quick pad changes on the job.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3 in diameter with 0.3 in thickness:\u003c\/strong\u003e Compact size and working thickness suited for detailed work and edge areas where larger pads cannot reach.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e9-piece pack:\u003c\/strong\u003e Multiple pads in the kit reduce downtime from wear and help maintain consistent performance across a project.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe ComeFloor polishing pucks are aimed at professional concrete grinders and maintenance crews using ride-on or walk-behind grinders who need a transitional tool to bridge metal bond grinding and final resin polishing.
