How to select the right IRWIN step drill bit set for metal drilling?

For metal drilling, choose the IRWIN 10502cb set with black oxide cobalt bits, which resist heat and wear. The 135° split point reduces walking. Ensure your drill is not impact rated, as these bits are not designed for impact drivers. Use cutting oil for best results.
