Does anyone know of a source for ER16 collets ground to INCH
fractional sizes?
I'm not interested in the dual metric/inch type or high dollar high
precision types.
These used to be availble from Enco, etc.
What I mean is, for instance, a loose 1/4" collet will accept a .250
tool shank
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
extra screwing
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,

Thanks George,
but as shown in the specs chart those are actually metric collets.
The 1/4" collet max dia (the loose dia) is .275" (7mm).
It seems no one is making these in fractional inch sizes anymore.

Sure they do Rich.
I buy them all the time but I can't recall the manufacturer off hand.
I order from a local tool supplier that knows I'll send back a metric collet
if I've ordered an inch size.
They take care of it. I know Regofix makes them but that isn't what I'm
getting.
