Frequently Asked Questions
The “A66N” is Kyocera’s proprietary PVD-coated ceramic/cermet grade—optimized for hardness, thermal stability, and wear resistance in challenging turning operations.
It performs best on hardened steels, cast irons, and alloy steels under moderate to high cutting speeds, where wear and thermal loads are significant.
S01525 is a ground chipbreaker geometry by Kyocera — it balances chip control and cutting force, giving reliable performance across a range of depths of cut and feed conditions.
The CNGA 80° negative shape offers stronger edge support under heavier loads, is less prone to deflection, and is more forgiving in interrupted cuts. It's ideal for robust, stable turning operations.
