NEG Type / NEF Type

For Exotic Alloys and Stainless Steel Turning

General Features Application Range

NEG/NEF type chipbreaker for exotic alloy machining

can be used for Titanium alloys, heat-resistant alloys NEG

4,0 and a variety of other exotic alloys. NMU NEX

They deliver excellent wear resistance and superior

chip management. These chipbreakers can solve

quality problems caused by the unstable tool life and 2,0 NEF NSU

poor chip control provided by conventional chipbrea-

kers for exotic alloys. Feed Rate

NEG Chipbreaker for Roughing Provides excellent wear resistance and chip control from general-purpose machining to roughing applications. Reduces damage to insert and eliminates trouble from chips specific to exotic alloys. Also demonstrates very high versatility.

Crater wear advancement is prevented by the round Cross Section of Chipbreaker bumps, whilst maintaining excellent control. 1,75 0,09

The cutting edge Excellent chip manage- 30°

maintains the strength ment and wear prevention slowing the progress is delivered by the special of crater wear. rake face design. Cutting Performance – NEG Type
