How to Drill a Hole in Hardened Steel
Drilling through hard steel is nothing like drilling through wood. Wood is a very soft material compared to hard steel, and can be drilled through quickly using a wood bit without any lubrication. Hard steel should be lubricated with oil before you drill into it, and it's important that you use a cobalt bit and drill into the steel very slowly. When you are at the hardware store buying your drill bit, the package will clearly indicate if it's meant for steel. Does this Spark an idea?
