Could you help me identify a box of imperial collets please.
They comprise of a body and a seperate locking nut. The body has a profile of a flat countersunk head rivet. Just over an inch in total length and approx 13/16 o/dia. They all have three equally spaced slits running about three quarters of the length of the body.
They look similar to pictures of the Bristol Ericson Acramil “G” or “F” type but the locking rings do not have outside wings for tightening instead the underside of the ring as a 3/16 deep groove to accept a 5/8 wide bar.
Many thanks
Clive
