• Best For: Lapidary saws that accept an 8-inch (203mm) blade on a 5/8-inch arbor.
• Highlight: The 8-inch (203mm) MK-301 Gemking, with the same 0.040-inch kerf and 5/8-inch arbor as the 6-inch and 10-inch versions.
• Expert Note: Choose this over the 6-inch for deeper cuts when the saw takes 8-inch blades; the arbor does not change, only the diameter.
