• Highlight: MK Diamond MK-303 sintered metal-bond continuous-rim formulation cuts gemstone, agate, jasper, and jade smoother and faster than notched-rim or plated alternatives, with a thin kerf that minimizes material loss on expensive lapidary rough.
• Best For: Lapidary cutters stepping up to 8-inch trim and slab saws for larger nodules of agate, quartz, jasper, and petrified wood where deeper cut capacity is needed.
• Expert Note: 8-inch diameter; oil-based coolant required. Continuous rim and sintered diamond bond produce smoother cuts and longer life than equivalent plated alternatives on hard gem rough.
