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, RichD, Atlanta
