Why reaming is done?

The rotary cutting tool used in reaming is known as a reamer. However, reamers remove significantly less material than drill bits. The primary purpose of reaming is simply to create smooth walls in an existing hole. Manufacturing companies perform reaming using a milling machine or drill press.
