• Best For: Contractors running 12" saws who cut a mix of concrete and masonry and need a blade with a 1" arbor.
• Highlight: The 12" MK-299D has a .100" width and a 1" arbor, thinner than the .125" width of the 14" MK-299D.
• Expert Note: Confirm the saw takes a 12" blade on a 1" arbor before ordering; the .100" width is the kerf to plan for, and the 14" MK-299D is the choice for larger saws.
