The NP-9-27 Stationary Head compliments the Nowak NP-9-27-OS Oversize Stationary Head and the patented Nowak Boring Process. The nature of the Nowak Boring Process assures exact alignment of the revolving and stationary heads which will guarantee reliability and repeatability in production.






We supply all Davenport customers with the only alternative source for purchasing a stationary head for either a machine rebuild or standard replacement. The Nowak NP-9-27 Stationary Head offers uniform tapered tool spindle bore location, i.e. relief for easier installation of the center drive attachment support bearings.
