Ive been searching for a new collet chuck ER40 with MTA4 12m draw bar
My mill is MT4 and all the MTA4 tappers i have are all 12m drawbar .However after searching for hours online it seems all MTA4 morse stuff seems to have 16M or 5/8 Drawbar sizes ?.This would not be an issue but i cannot fit M16 or 5/8 Drawbar in my Mill.
At tbe momment im using a ER40 MTA3 With a MT3 to MTB4 adaptor but i cannot use a draw bar with this set up as as the MTA4 does not have a draw bar hole .I thought about drilling and tapping the MTB4 out but this still leaves the MT3 to come loose from the adaptor.
Has anyone had this problem before and any good ideas for a solution much appreciated .
In the picture you can see the MTA3 on the collet chuck and MTA4 tappers are all 12mm size.
I May have my a and bs around the wrong way I'm not sure sorry if I have
