A 1/2" shank is about as big as you need on smaller mills. You may be able to use a 5/8 endmill with a 1/2" shank. I have a couple in my stash, but not sure the smaller mills can drive them adequately.?

I???? bought a set of MT2 Weldon shankendmills from All Industrial tool a few years back . I think it was a 5 or 8 piece set . WHen? traded that mill & holders for a nice Mig welder a couple weeks ago I had only used the 3/8 & 1/2 holders in 5 years . I don't think I would buy anything larger that 3/4 for these mills & that may be pushing the machine too far . I found like may users that ya lost some real-estate when using the end mill holders over using collet's . Being on the conserve my energy club I was not a huge fan of? raising & lowering the head a bunch so I pretty much stick with the collets .

You can use MT2 collets as tool holders. LMS only has them with a 3/8-16 thread but you should be abke to find them with the M10-1.5 thread on Amazon or ebay. Amazon has an MT2 to ER25 collet holder with metric threads, too. And you could make a 3/8-16 drawbar, too, if you can't find metric threaded MT2 collets.?

You can probably find MT2 endmill holders for Weldon-shank endmills. I got a few years ago for an Atlas mill. Or you can get MT2 blanks that you can make into endmill holders.?

Good luck, and have fun!

Problem solved.

It is like a bigger mill, unscrewed the draw bar a little and hit it with a piece of aluminum and hammer. It came loose. It is a #2 Morse with a threaded hole of 10X1.5 MM. the other end had a chuck on it at one time. The mill is an older Harbor Fright model. I got it at an estate sale for $125 and came with two chucks with it. I can take one of them off and put on the shank. Now to find threaded shanks for end mills.

Thanks to everyone.
