Does anyone know of a source for ER16 collets ground to INCH
I'm not interested in the dual metric/inch type or high dollar high
These used to be availble from Enco, etc.
What I mean is, for instance, a loose 1/4" collet will accept a .250
and hold it lightly or nearly so.
The 6-7 mm (.275" bore) 1/4" equivalent has the be closed most of the
way to grip.
These are just a pain to use with fractional inch shanks with all the
and unscrewing and when the collet pops loose suddenly the tool drops
out if you don't
have a finger ready to hold it.
I'm sure the runout accuracy suffers, but the self holding feature is
what I miss.
Thanks for any help,
