All About Quick Change Tool Posts
As some of you know our E-Model metal lathes come with a pretty cool feature, a quick change tool post and four tool holders. And lately some questions have come up about sizes and industry standards when talking to customers about this topic. Here’s what I can tell you about it.
- Our E model lathes come with a tool post with model number of 250-200. This tool post is imported to the US under the name Phase II. These tool holders with hold up to a 5/8” square tool. The holders for this tool post can also be bought separately by doing a Google search of “250-202 quick change holder” or “250-201 quick change holder”. Now, both of these will do the same thing, but the 250-202 has a V-Groove in the bottom of the holder so it can hold a boring bar.
- Some customers do not recognize this style of tool post and holder, but there is an industry standard that they will know. The 250-200 is the same as “BXA” style and the 250-201 is a BXA-1 and the 250-202 is a BXA-2
- Now, there are other tool holders and tool posts available. In the Phase II style there are models 250-100, 250-200 and 250-300. The 100, 200, 300 designates the size of the tool post and holders. The corresponding numbers for these are AXA, BXA, and CXA. The 100 or AXA being for 1/2″ square tooling, 200 or BXA for 5/8″, and 300 or CXA for 3/4″.
- Remember, if you have a 200 series tool post, only 200 or BXA series tool holders will fit it and in order to use other tool holders different tool post will have to be bought.
