Nmtb30 collet

[craigc1947]

Hi, on my recent purchase of a Chinese mill/lathe I am having problems finding collets for it. It looks like uses nmtb30 collet. Is there any other options or equiv. number for it. It seems like this is pretty rare here in the U.S.
thanks,
craig

If the mill spindle is NMTB30, many folks would take this approach... http://www.shars.com/products/view/258/ER40_NMTB_30_Collet_System

What kind of mill is it?

Hi,
one of the problems I've run into with the mill section is that the draw bar is 12mm. Most bars that comes with English sets (which is what I want) are either 1/2" or 3/8", metric draw bars that I've found are 10mm with metric size collets.The motor on this 3 and 1 machine is only .7hp so I think anything greater than a 1/2" er25 collet would be over kill. I have found one collet set that would suit me but it does have a 1/2" draw bar. Any more inputs?
Thanks again,
craig

Craig,
you can make a drawbar that will fit the standard nmtb tooling; couldn't be too hard. You already have the length on your existing drawbar, and all you would have to do beyond that is find a nut to weld onto the top.
