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

FWIW -- I have ordered items from HHIP and been pleased with their quality and service. Note that they are the "commercial" side of "The Little Machine Shop"

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. RichD

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.
