• Best For: Contractors sawing asphalt overlay where the cut has to pass through the new surface lift and into what is under it, which the 18-inch MK-7625W diameter allows in a single pass.
• Highlight: The 7625W is graded for overlay rather than general masonry - the abrasive, still-green surface course that dulls a concrete-grade blade quickly.
• Expert Note: An 18-inch blade needs a saw rated for that diameter and the matching guard; fitting this MK Diamond blade to a 14-inch machine is a guard-clearance problem before it is a cutting problem.
