ABSTRACT:
A chuck having a spring collet is disclosed. The spring collet has a plurality of pairs of adjacent collet segments with interstices formed between each of the collet segments. The interstices of the collet each having radially extending cutout seats with resilient stoppers received therein which extend between a tool received in the collet and the body of the chuck to prevent coolant from leaking therebetween when flowing through the collet by way of a duct in the tool. The stoppers of the collet are axially spaced from each other so as not to weaken the collet.
