• Best For: Concrete polishing crews running Edco grinders who need the refining-grit step ahead of resin-bond polishing.
• Highlight: This 120-Grit Single Diamond Grinding Dot removes the 70-grit scratch pattern and refines the slab surface for the transition into finer polishing stages.
• Expert Note: The hard-bond matrix is matched to softer or abrasive concrete, holding the Edco Diamond longer so the Dot lasts across more square footage per set.
