Boring

Boring is an operation in which a hole is enlarged with a single
point cutting tool.

A boring bar is used to support the cutting tool as it extends into
the hole.

Because of the extension of the boring bar, the tool is supported
less rigidly and is more likely to chatter. This can be corrected
by using slower spindle speeds or by using a smaller radius on
the nose of the tool.
