- Increases holding power by 75%
- Balanced up to 25,000 RPM
- Better rigidity and T.I.R. (runout)
PowerCOAT 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.
