ER collet ER25-A/ER32-A/ER40-A

The precision is 5μm If cutting tool's clamping less than 2/3 the length of collet's inner hole, the collet will be caused permanent damage The clamped length equal to the length of collet's inner hole can be obtained the best clamping accuracy and clamping force The diameter of cutting tool shank must not be larger than the maximu claming diameter of the collet In order to guarantee the accuracy of the collet, it is recommended to clamp the tool shank with fixed diameter Clamping range： ER11 is 0.5mm ER16 and above: 1.0mm
