• Best For: Shops cutting large pieces of agate, petrified wood or jade on an 18 inch lapidary saw with a 1 inch arbor.
• Highlight: The 18 inch (457mm) MK-301 Gemking keeps the .085 inch kerf shared with the 16 and 20 inch sizes, so only the diameter changes among those three.
• Expert Note: Check the saw's maximum blade diameter before ordering, since 18 inches is two inches larger than the 16 inch blade, and the blade needs a 1 inch arbor.
