Applications
This turning insert was primarily designed for finishing special materials and heat-resistant super alloys in modern precision manufacturing. The design is exceptionally well-suited for continuous cutting conditions and fine depths of cut, where strict dimensional accuracy and clean surface finishes are required.
Thanks to the sharp, negative cutting edge of the CNGG shape combined with the specialized chip former, demanding turning operations can be executed with high process reliability. This makes the insert a practical choice for demanding industries such as aerospace and medical engineering.
Special features
At the core of the insert is the advanced PVD-TiAlSiN coating, which offers exceptionally high thermal resistance. This protects the cutting edge against thermal overload and premature wear. The product is supplied in a durable packaging unit of 10 pieces, ensuring straightforward storage and safe handling on the shop floor.
