• Highlight: MK Diamond MK-303 16" (406 mm) Professional segmented-rim lapidary blade — segmented design adds chip clearance for faster slabbing of larger, harder gemstone specimens.
• Best For: Lapidary shops cutting larger rough — agate nodules, petrified wood logs, large jasper, and dense hardstone — where speed of cut matters as much as finish.
• Expert Note: Above 14" MK Diamond switches the MK-303 to a segmented rim so coolant can flush slurry through the gullets; this size still demands petroleum or synthetic oil coolant for proper rim cooling and long life.
