PVD coated grades Increased durability and performance: New generation of turning grade
UK — Manufacturer and supplier of tools for the metal cutting industry, Dormer Pramet, has upgraded its flagship PVD grade T8330 with a new coating generation, providing increased durability and performance.
The T8430 is the latest addition to Dormer Pramet's grades for general turning and heavy roughing. Developed for steel and cast steel, this grade also performs well in stainless steel, cast iron and super alloys, even in unfavorable conditions.
A multi-layered PVD coating optimised for increased productivity, the T8430 provides up to 69 % more durability compared to the previous T8330, the company states. This is especially the case when machining raw steel blanks or difficult materials, such as Inconel and Stellite. A 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.
