1)Runout of our ER collet are within 0.005mm-0.015mmm
2)ER8, ER11, ER16, ER20, ER25, ER32, ER40 and ER50 collet
3)Made of high quality steel:65Mn
4)ER Collet Packing:inner packing is plastic or paper box,the outer
packing is cartons.
5)We normally supply two kinds of accuracy: first accuracy 0.008mm,second accuracy 0.015mm. The highest accuracy is 0.005mm.
6) Inspection:100% collet inspection.
ER collet with a precision of 0.008mm means that the collet can securely hold a tool or workpiece with an accuracy of 0.008mm. This level of precision ensures that the tool or workpiece is held tightly and accurately, minimizing any potential errors or inaccuracies in machining or cutting operations. ER collets are commonly used in CNC machining and other precision manufacturing processes.
Spring collets that comply with the DIN 6499 standard are widely used in the metalworking industry for various machining operations, including drilling, milling, and reaming. They are compatible with machine tools that have a corresponding spindle design and are interchangeable within the specified size range.
