How to select the right IRWIN step drill bit set?

Select the IRWIN step drill bit set based on the material thickness and hole sizes needed. For general metalworking, the 3-piece set covering 1/8" to 3/4" is versatile. Ensure your drill is not impact rated, as these bits are not designed for impact drivers. Use cutting oil for longer life.
