--In machining, boring is the process of enlarging a hole that has already been drilled (or cast), by means of a single-point cutting tool (or of a boring head containing several such tools), for example as in boring a gun barrel or an engine cylinder. Boring is used to achieve greater accuracy of the diameter of a hole, and can be used to cut a tapered hole. --Boring can be viewed as the internal-diameter counterpart to turning,which cuts external diameters.

Boring head can be easily adjusted to different boring needs for maching on demand.Boring depth can be extended by tool connection.
