Bridgeport Series I Milling Machine


Features:

Today, the Series I Standard continues to fulfill the industry's need for an accurate, reliable, and versatile mill.

The Series I Standard features an innovative airflow cooling design that uses no external fans to prolong bearing life and prevent expansion from heat build-up. A full range of accessories are available, including optional chrome-plated ways and gibs to ensure that the machine will last a lifetime.
