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 fixture.
Collets are available for: drilling, milling, coolant thru, and high-speed applications. Special “DNA” Dead Nuts Accurate collets are used for small drills (6mm and smaller) to maintain T.I.R. at those sizes.
Use “Power Coat” nuts to increase the holding power and safety of your tool holders. High holding power extends cutting tool life and improves surface finish.
