What is an End mill?
End Mills are used for making shapes and holes in a workpiece during milling, profiling, contouring, slotting, counterboring, and drilling applications.
They are designed with cutting teeth on the face and edge of the body and can be used to cut in several directions.
According to the five most common end mill types, we will introduce how to read the specification sheet one by one, and the precautions to help you quickly find the size you need!
