Inserts Depth of Cut (mm) Chipbreaker NFE Type / NFB Type New Negative M Class Chipbreakersfor Low Carbon and General Steel Turning General Features The high performance NFE type, which ensures stable chip control in a wide range of feed rate, has been added to the chipbreaker series for low carbon steel and general steel turning. Extensive product lines are available to meet various machining requi- rements. A positive insert execution of chipbreaker NFB is also available.
