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.

Iron ore mining and dressing
The iron ore extracted in the deposits, mostly by blasting, is initially very coarse and unwieldy, which gives this untreated rock the name coarse ore. After the coarse ore has been extracted, it is crushed directly at the deposits with the aid of cone crushers or jaw crushers to more manageable sizes of approx. 15 mm.
