Chipbreaker NGU Type
For positive Inserts
Superb versatility handles processes from roughing to finishing. Stable machining is realised across a range of conditioins through excellent cutting edge sharpness and strength. Item range covers a wide variety of applications.
Chipbreaker NFE Type / NFB Type
Negative M Class Chipbreakers for Low Carbon and General Steel Turning
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 requirements. A positive insert execution of chipbreaker NFB is also available.
Chipbreaker NGH Type
For Hardened Steel Turning
Enables medium roughing of hardened steel in combination with coating and grade AC503U. Reduces heat generation and enables deep cutting (ap = 1–3 mm) of hardened steel by using a wide neutral ground chipbreaker (rake angle: 4°) and sharp edge. Discharges chips smoothly.
Chipbreaker NEG Type / NEF Type
For Exotic Alloys and Stainless Steel Turning
NEG/NEF type chipbreaker for exotic alloy machining can be used for Titanium alloys, heat-resistant alloys and a variety of other exotic alloys.
They deliver excellent wear resistance and superior chip management. These chipbreakers can solve quality problems caused by the unstable tool life and poor chip control provided by conventional chipbreakers for exotic alloys.
Chipbreaker NEM Type
Chipbreaker for Stainless Steel Turning
The NEM chipbreaker achieves excellent fracture and crater resistance and ensures extremely stable machining
Chipbreaker NFB Type / NLB Type
Positive M Class Chipbreakers for Low Carbon and General Steel Turning
The NFB type for finishing and the NLB type for light cutting have been added to the chipbreaker series for low carbon and general steel machining in addition to the already present NLU type for finishing and NSU type for light cutting. The NFB and NLB type chipbreakers improve chip control in finishing of low carbon and general steel.
Chipbreaker for Steel Turning (M) NSI Type
Nose radius with minus tolerance (M)
– Sharp designed cutting edge with low-cutting force
– Better chip control in wide range DOC for bar feeder machine
– Combination of high rake edge design and G-class precision offers superior cutting performance
