• Highlight: MK Diamond engineered the MK-303 6" rim with the same continuous diamond edge as the 4" version, but the larger diameter cuts thicker slabs in one pass — ideal for stepping up from cabbing trim work into slabbing.
• Best For: Lapidary slab cutters, intermediate gem cutters, and rock collectors working with larger nodules of agate, jasper, petrified wood, and softer gemstones.
• Expert Note: The 6" (152mm) diameter delivers ~2.5" depth of cut, fitting standard slab and trim saws with 1/2" or 5/8" arbors at typical 3,400-4,500 RPM operating speeds.
