GMT Inch ER Collets

GMT Inch ER Collets

Extended-Range ER "spring" collets have a gripping range of 1mm, or 0.040", the most of any collet commonly used in tool holding. As an example, a 1/2" collet will compress from 0.500" down to 0.460".

Note: The ER16 collets have a gripping range of 0.5mm or 0.2". 

Glacern inch sized collets have true nominal inch bores, minimizing compression for maximum concentricity and minimum runout. All collets are precision ground for less than 0.0002" of indicated runout.

NEW! Glacern Coolant collets are now available in ER16, ER25, and ER32 sizes identical to their normal non-coolant counterparts. The difference is that the coolant collets are meant to be used with thru-coolant tools and pull studs allowing greater water pressure through the collet.

Note: ER Chucks, Holders and End Mills shown are sold separately
