Für die kontinuierliche-leichte Unterbrechungsbearbeitung ｜ CBN für die Bearbeitung von gehärtetem Material
Hardened steel – Finishing
The first recommended material for continuous to light interrupted machining,
with a coating that has excellent wear resistance.

Alloy steel（HRc62）
vc = 150m/min, f = 0.1mm/rev, ap = 0.2mm, Continuous
A multi-layer coating with excellent wear resistance and chipping resistance is used,
making this a versatile material that can be used for continuous to interrupted machining.
