DIN6499B ER collet CNC lathe milling collet

The "ER" name came from an existing "E" collet (which were a letter series of names) which Rego-Fix modified and appended "R" for
"Rego-Fix". The series number is the opening diameter of the tapered receptacle, in millimetres. ER collets collapse to hold parts
up to 1mm smaller than the nominal collet internal size in most of the series (up to 2mm smaller in ER-50, and 0.5mm in smaller
sizes) and are available in 1mm or 0.5mm steps. Thus a given collet holds any diameter ranging from its nominal size to its
1mm-smaller collapsed size, and a full set of ER collets in nominal 1mm steps fits any possible cylindrical diameter within the
capacity of the series. With an ER fixture chuck, ER collets may also serve as workholding fixtures for small parts, in addition
to their usual application as toolholders with spindle chucks.Although a metric standard, ER collets with internal inch sizes
are widely available for convenient use of imperial sized tooling. The spring geometry of the ER COLLET is well-suited only to
cylindrical parts, and not typically applied to square or hexagonal forms like 5C collets. Spring Collet,Precision Collet,Oz Collet,Din 6499 Collet.
