✅ Tip #1: Metal needs to be drilled at low speeds; the larger the diameter, the lower the speed. It is also recommended to drill steel with coolant to prevent high tooth tip temperatures from cracking the cutting edge.
✅ Tip #2: By applying a light coating of anti-corrosion oil to the filter surface, you can prevent natural oxidation and prolong the hole saw lifespan. Do not exceed a cutting depth of approximately 1-1/2" (38mm) with this tool.
