ER Collets

ER Collets

ER Collets

ER collets are used extensively in machining applications. In milling, ER collets are used to hold end mills, drills, taps, and reamers. In turning, ER collets are also used to hold small diameter boring bars. They can also hold small diameter round parts in milling and grinding applications.

ER collets have a clamping range and can be collapsed to hold slightly smaller hold diameters than the indicated size. The clamping range for most ER collets is +0/-.039 (+0/-1 mm); for ER collets smaller than 7/64, the clamping range is +0/-.015 (+0/-.5 mm). Tormach ER collets are made from hardened alloy spring steel and have run out of 0.0003 or less.
