What is difference between mill and mill-drill?
Ans) Today many manufactures are combining machines; a mill/drill is one of these. It is a mixture of a drill and a mill, a mill removes stock from material (usually metal, but not limited just to metal, it depends on your application), you use fluted cutters like end mills. The drill aspect of the machine is just that it drills holes, with the proper speed for the right size drill.
