• Best For: Lapidary operators with a 20 inch saw cutting the largest hard-material slabs such as agate, petrified wood and jade.
• Highlight: The 20 inch (508mm) blade is the largest MK-301 Gemking listed, with a .085 inch kerf and a 1 inch arbor.
• Expert Note: The higher diamond concentration and solid sintered kerf improve cutting and coolant flow, which matters on the deep cuts a 20 inch blade is bought for.
