Used Vertical Milling Machines for Sale

Shop used Bridgeport mills for sale on Aucto — Series I and Series II vertical knee mills, plus Bridgeport-style verticals (J-head clones and later knee mills) from verified sellers across the US and Canada. "Bridgeport mill" is what buyers type when they want this machine: 9×42 or 9×48 table, R8 (or NT30) spindle, 1–2 HP, the toolroom mill every shop already knows how to run.

Confirm whether the machine is a genuine Bridgeport or a style-equivalent, then read table size, spindle taper, speed range (typically 60–2720 RPM on a J-head), power feed, DRO, and whether the head is a true J-head. Series II machines are the heavier 4 HP class. TRAK and other CNC-assisted verticals also appear in this list when they are knee or bed verticals rather than enclosed VMCs.

Can I still buy a used Bridgeport mill?

What is the difference between a Series I and a Series II Bridgeport?

Series I is the standard 1–2 HP J-head knee mill (typically a 9×42 table). Series II is the heavier mill — more horsepower, a larger table, built for more aggressive cuts. Both appear on this page when they are in stock.

Will a Bridgeport-style mill show up here too?

Yes. Buyers searching "Bridgeport mill" usually mean this class of vertical knee mill, including well-known clones. Each listing names the manufacturer so you can see exactly what you are buying.
