Features:
For more than 60 years, the Bridgeport Series I Standard Mill - the original, all-purpose mill - has been the "real thing" in milling, drilling, and boring for metalworking shops throughout the world. 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.
Series I Standard Features Include:
Chrome dovetailways and gibbs
Way Cover
Servo X-axis power feed
