Drilling Process and Machine

There are many machines capable and used to drill, ream or thread holes in a part. Drilling is the manufacturing process where a round hole is created within a work piece or enlarged by rotating an end cutting tool, a drill. Reaming is a similar process where a hole feature is enlarged to a very specific or accurate size by introducing a rotating end and side cutting tool called a reamer.

Drilling and reaming machines vary from the tiny bench machine used for high quality jeweler's operations to the heavy-duty machines that bore large holes. Some of the most commonly used drilling machines are: drill press, milling machines, and lathes.
