YG-1 has introduced YG904, a new PVD coated milling grade developed to meet the growing challenges of machining difficult-to-cut materials. Engineered with a specially developed substrate and advanced PVD coating technology, YG904 delivers stable and consistent performance in demanding milling environments.
The newly developed coating provides exceptional resistance to thermal cracking and maintains reliability under high-impact and unstable cutting conditions. As a result, YG904 grade ensures consistent surface finish, reliable tool life, and process stability.
YG904 grade performs effectively in both interrupted and continuous cutting operations and is well suited for machining high-temperature alloys, titanium alloys, and martensitic stainless steels, where durability and repeatable performance are critical. To enhance application flexibility, the grade is available in various insert styles, including APKT, ENMX, round inserts, and the TPKT series, covering most general milling requirements.
All YG904 inserts are fully compatible with existing YG-1 milling cutter bodies, allowing users to upgrade performance without additional tooling investment, thereby providing a practical and reliable solution for high-performance milling of difficult-to-cut materials.
