ER40 standard type standard precision (<15 micron runout) ER collets, available in diameters from 2mm to 32mm. The standard type, standard accuracy variants of ER collets - the world's most widely used clamping system, used for a wide array of high precision machining applications. 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 it’s 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.
