• Highlight: MK Diamond MK-303 30" (762 mm) Professional segmented-rim lapidary blade for the largest production slab saws cutting oversize gemstone rough.
• Best For: Commercial lapidary and rockhound operations slabbing very large specimens — petrified wood rounds, big agate, jasper, and oversize hardstone.
• Expert Note: At 30" the MK-303 demands a properly tuned slab saw with full oil-coolant bath; segmented-rim design clears slurry from deep cuts and the diamond matrix is engineered for hundreds of slabs of service.
