⭕ This is a 4 station indexer that I had running on my Brother drill/tap machine. It uses a standard 5c collet. It can be used in either the horizontal or veritcal position but I used it horizontally. The distance between centers on the collets is 2.5 inches. The unit has air over hydraulic system for clamp/unclamp and braking. This is a dead length set-up which means that the bar stock does not pull back when the collet is closed. Included in the sale is the controller for indexing, air over hydraulic set-up as shown and manuals. I am also including the bar support system along with the plastic trays to catch the parts. I had the machine programmed to run continuously with the machine also doing the bar pull at the end of each cycle. This is a very nice unit that performed flawlessly. Shipping available.
