• Best For: Contractors cutting concrete, masonry, brick and block with a saw that takes a 12-inch blade on a 1-inch arbor.
• Highlight: Varying-size cooling slots eject cutting debris and maximize air flow to help keep the blade cool, here in the .125-wide, 1-inch arbor version.
• Expert Note: Choose 160989 for a 1-inch arbor; the otherwise identical 12-inch MK-565SKMR with a 20mm arbor is sold as 160989Z, so verify your saw arbor before ordering.
