Hi Ron
That's why I am pleased that my milling machines use R8 collets, which are
relatively cheap. I also use R8 arbours with soft blank ends and bore
these to size, with an Allen screw in the side, to engage a flat on the
endmill - a free-hand ground flat will do. These are also available
complete in a series of bores. I use ER25 collets on my little lathe, and
have an R8 adapter for these. By an unusual serendipity, my ancient
horizontal milling machine also uses R8, so that I can use them on it and
also on my VMC vertical mill. They are much more secure than 2 or 3 MT,
and far easier to eject..
Cheers! Hubert
