Reaming

Reaming is a cutting process in which an existing hole is enlarged and accurately sized by means of a multi-fluted cutting tool.  As the reamer and workpiece are advanced toward each other, chips are produced by shaving thin sections from the existing hole.  A reamer is an accurate tool and is designed for removing only a small amount of material.
