The MK Diamond MK-303 6-inch blade is a professional continuous rim lapidary blade made for cutting rare and valuable materials such as agate, quartz, petrified wood, jasper and jade. A thin kerf and a smooth continuous rim are the reason hobbyists and lapidary shops choose it when cutting waste matters.
This size (part number 153630) is 152 mm across with a .032-inch blade width and a 1/2-inch arbor. MK Diamond designs the MK-303 for use with water-soluble coolant, and the 5mm rim height suits slab and trim work.
Use cases
- Gemstone and slab cutting. Slice agate, jasper and jade rough into slabs with minimal waste.
- Lapidary hobby shops. Keep a spare thin-kerf blade ready for your trim saw.
- Fossil and petrified wood. Cut valuable specimens where a smooth, controlled cut matters.

Fit and compatibility
Check the arbor size and maximum blade diameter on your lapidary saw before ordering. This blade has a 1/2-inch arbor. Dry and oil the blade before storing it to protect the core.
Getting the most from the blade
Match the blade diameter and arbor to your saw, keep the blade guard in place, and let the blade do the cutting rather than forcing it through the material. Steady feed pressure and, where the blade is designed for wet cutting, a steady water supply keep the cut cleaner and help the blade last. Wear eye, hearing and respiratory protection and follow the saw maker and MK Diamond safety guidance.
