• Best For: Lapidary shops with a saw sized for 18-inch blades on a 1-inch arbor that want more cutting depth than the 16-inch while still running a .085 width.
• Highlight: The 18-inch is the larger of the two MK-303 sizes that keep the thin .085 width, so bigger specimens can be cut without moving up to the .100 width of the 20-inch.
• Expert Note: This part number is the 18-inch only; the 16-inch is 156728 and the 20-inch moves to a .100 width, so match blade diameter and width to your saw before ordering.
