The ER collet system by Rego-Fix is useful for various machining applications, including boring, milling, reaming, tapping and grinding. The collets are available in two levels of precision—standard and ultra-precision (UP). Offered in standard and metric sizes, the levels range from the ER 8 series to the ER 50 series. This selection can accurately clamp tool shanks ranging in size from 0.0079" (0.2 mm) to those shanks as large as 1.3386" (34 mm).
Collets for tapping applications are available in rigid tapping and axially compensating tapping styles.
