• Best For: Contractors cutting concrete, brick, and block who need the 18" diameter of the MK-565SKMR series on a 1" arbor.
• Highlight: The 168040 is the 18", .142-inch-wide blade in the MK-565SKMR line, with varying-size cooling slots that eject cutting debris and keep the blade cool.
• Expert Note: Match both the 18" diameter and the 1" arbor to your saw before ordering; other sizes in the MK-565SKMR line use different diameters, widths, and arbors.
