• 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 hobbyists, rockhounds, and gem-cabbing operations running 4-inch trim saws on agate, quartz, petrified wood, jasper, and softer gem rough where smooth cuts reduce subsequent grinding time.
• Expert Note: Use with petroleum, synthetic, or mineral-oil coolant (NOT plain water) for full blade life and cut quality; never run dry. The continuous rim preserves edge cleanliness across hundreds of trim cuts in agate or jasper-class material.
