PowerCOAT increases holding power by 75%. Balanced to 70,000 RPM. Better rigidity and less T.I.R. than standard nuts.

€œPower Coat€ is an innovative, permanent coating that increases clamping pressure of the nut up to 75% compared to standard ER nuts. More holding power reduces the chance of spinning the shank of the tool inside the collet, which can cause premature failure of the collet.
