Morphology

collet + chuck

The compound directly combines two nouns whose meanings specify a subtype: a 'collet' (a cone-shaped clamping insert) and a 'chuck' (a tool holder/jaws). A learner who knows both constituents can readily infer it denotes a chuck that uses a collet, so the meaning is compositional and predictable.

Etymology

Collet chuck comes from two parts: a collet is a small cone that squeezes around a round object, and a chuck is a holder. So a collet chuck is literally a cone-in-a-holder used to 'clamp' round pieces tightly, which is why the name means 'a clamp that holds round pieces so a machine can work on them accurately'.
