At Westec, Techniks (Indianapolis, IN) will display its steel-sealed, ER coolant collets, which do not have any plugs or seals to fail, so the user can run continuously without worrying about coolant issues. They are as easy to use as standard ER collets, and do not require coolant discs. Rated to 2,000 psi, the collets work with standard ER holders and nuts. ER 16, ER20, ER25, ER32 and ER40 steel-sealed collets are available in all popular inch and metric shank sizes. For the best T.I.R. (accuracy) and extended cutting tool life, the company recommends its “Power Coat” nuts that hold up to 75 percent tighter than standard nuts.
