NEF Chipbreaker for Finishing The NEF chipbreaker reduces chip curl diameter in finishing applications. Provides extremely good chip management not fluctuated by the material in use.

Main chipbreaker that enables good chip control even at low Cross Section of Chipbreaker depths of cut. 1,2 20° Sharp edge with 20° rake angle reduces wear. The grooves on the rake face reduce heat and assist chip flow away from the workpiece.

Cutting Performance – NEF Type

Heat Resistant Alloy

Chipbreaker type: NEF (AC510U) Work Material: Conventional tool (S10) Competitor‘s product (S10)

Inconel 718 Insert: CNMG120408 Cutting Data:

v c = 55m/min d = 0,3mm oc f = 0,15mm/rev

Ti-6Al-4V Insert: CNMG120408 Cutting Data:

v c = 80m/min doc = 0,5mm f = 0,2mm/rev Improvements in chip control and chip removal Wet management based on small curled chips. There is a problem in the length and the diameter of chips. Tc = 25min

Application Example – NEF Type

Inconel 718, shaft component Duplex stainless steel cover

Great improvement in Improvements in chip chip management. Keeps management. Suppress
