ER32 collet chuck for use in Morse taper 3 (MT3 - DIN 228) spindle tooling systems - 70mm gauge length with standard nut. Balanced to G6.3 at (15,000RPM). ER collets are the world's most widely used clamping system, owing to their exceptional precision and strength when clamping cylindrical objects. Due to the manner in which the clamping force is exerted evenly around the tool from all directions, clamping using ER collet chucks does not suffer anything like the level of runout inherent with the use of most other tool holding systems and can be used in 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 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.
