• Highlight: The MK Diamond MK-301 Gemking 20-inch lapidary blade is built for serious slab-saw work, cutting agate, jade, petrified wood, and other hard gem rough up to 9 inches thick in a single pass.
• Best For: Professional lapidary shops and commercial gem cutters running 20-inch slab saws who need long blade life on hard, abrasive rough.
• Expert Note: Allow a 30-second free-running warm-up at full RPM before plunging the first cut - this seats the diamonds and noticeably extends the Gemking blade's overall service life.
