Dormer Pramet has upgraded its flagship PVD grade T8330 with a new coating generation, providing increased durability and performance for general turning and heavy roughing, even in harsh machining conditions.

Developed for steel and cast steel, the enhanced grade also performs well with stainless steel, cast iron and super alloys. A multi-layered PVD coating optimised for increased productivity, the T8430 provides up to 69% more durability compared to the previous T8330. This is especially the case when machining raw steel blanks or difficult materials, such as Inconel and Stellite.
​
A unique Titanium-Boron-Nitride (TiBN) top layer offers build-up edge reduction and improved performance, while a thick TiN coating gives low compressive stress for crater wear resistance.

​In addition, the hard AlTiN of the T8430 secures flank wear resistance, with a bright gold TiN layer to support wear detection. ​
