Sumitomo Electric Carbide Inc. has expanded its lineup to include EEG and EEF Chipbreakers for exotics and stainless steel alloys.

Designed for roughing applications, the EEG Chipbreaker features ball-shaped projection breakers for enhanced chip control. A two-step cutting edge at the front of this general-purpose breaker reduces crater wear and produces a superior surface finish when machining exotics and stainless steel alloys. The EEG performs with high wear resistance and chip control, reducing lead-time and increasing productivity.

The EEF Chipbreaker has been developed and thoroughly tested for high chip control during finishing operations. A unique slot on the rake face reduces heat generation and extends tool life, while a 20°Cutting edge reduces wear.
