  • Best Diamond Cutting Wheel for Gallium Nitride (GaN)?

    Posted by brianf on November 6, 2025 at 5:22 am

    I’ve been experimenting with different setups for cutting gallium nitride (GaN) and noticed how much difference the right diamond cutting wheel gallium nitride configuration can make. The material’s hardness and brittleness make precision cutting a real challenge.

    Has anyone found an ideal combination of grit size, bond type, and coolant flow for smooth, chip-free cuts? I’m currently testing sintered metal-bond blades, but open to hearing what’s worked best for you.
