    Material guidance

    Match the cutting setup to the panel—not just the diameter.

    The official name identifies HSS bi-metal construction, and Renogy’s gallery shows use on wood. For any other panel material, first verify that this cutter, your drill, the required speed and the available cutting depth are appropriate. Do not cut a finished installation until compatibility is confirmed.
