• Best For: Concrete and masonry cutters who need a compact 4-inch general purpose blade that mounts on a 20mm or 5/8-inch arbor.
• Highlight: Laser-welded segments with a 10mm segment height on a thin .080-inch width in the MK-299D standard grade line.
• Expert Note: At 4 inches this is the small MK-299D size; the 7-inch 156417 has a thicker .090-inch width and a DM-5/8 arbor, so confirm the diameter and arbor your tool takes before ordering.
