Techniks "Power Coat" ER Collet Nuts

 

Turn ER or TG toolholders into milling chucks

Reduce T.I.R. by increasing holding power
Increase tool life by up to 20%

This innovative, permanent coating increases clamping pressure up to 75% compared to an uncoated standard ER nut. More holding power reduces the chance of spinning the shank of the tool inside the collet, which can cause premature failure of the collet. "Power Coat" nuts also have an eccentric ring that holds the collet inside the nut when turned upside down. They are balanced for high-speed operations.
