Does anyone have a source for ER16 collets that are ground for INCH
fractional tooling shanks?
All the dual metric/inch marked collets are metric. Yes they will close down ok
on inch shanks, but it's very agrivating to do so. Just try the 1/4"
shank in a 6-7mm collet. It has to be closed almost all the way to grip.
Besides accuracy suffering, I hate the hazard of dropping tooling out when
the tool suddenly pops out with the collet being pulled loose.
A friend has the fractional ground jobs and a shank will stay in. Nice.
These used to be available from Enco.
Thanks for any help.
