ER Collets are a sub-type of Chuck, and are the most commonly-used Collet type in the world. They are designed to create a semi-flexible collar around a piece of tooling, which allows a Drill or similar Cutter to be held centrally and securely within a piece of machinery. ER Collets are commonly used alongside specialised ER Collet Chucks, which are specially designed to accommodate a removable ER Collet.
As ER Collets are manufactured with a series of slits to allow for flexibility and contraction, each size can support a range of shank sizes of either metric or imperial design.
