• 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 running 5-inch trim saws — the sweet spot between 4-inch and 6-inch for medium cabochon work, small slab work, and trimming larger nodules.
• Expert Note: 5-inch diameter; oil-based coolant required for cut quality and blade life. Thin continuous rim holds true across the full diameter and lasts through repeated cabochon and small-slab passes.
