Conversely, a slower speed will let you drill through cast iron without overheating the power drill and making the drill bit dull. So don't run over 3000 RPM while less than 1000 RPM is more preferable. A step bit is ideal for a large hole. If you need to drill a larger hole through cast iron, it will be better to use a step bit.
