ER collet chucks handle a wide range of machining jobs without having to buy new tool holders. Simply choose the right size collet for the job, set tool depth and tighten the collet nut and pull stud to the proper torque using a torque wrench and tightening fixure. Collets are available for - drilling, milling, coolant-thru and high speed applications. Special "DNA" dead nuts accurate collets are used for small drills (6 mm and smaller) to maintain T.I.R. At those sizes. Use "PowerCOAT" nuts to increase the holding power and safety of your tool holders. High holding power extends cutting tool life and improves surface finish.

- Collet chucks are balanced to 25000 rpm at G2.5 tolerance
- They are individually lab tested for accuracy and balance and come with their individual performance report
- Holders achieve 0.0001 in or less T.I.R as measured from the taper to the collet pocket
- Taper is ground to AT3 accuracy or better
