Applications
This indexable turning insert provides excellent performance in everyday steel turning tasks. It is primarily designed for medium chip cross-sections and excels in continuous cutting environments. Thanks to the inherent toughness of the P20-P30 carbide substrate, it is also highly capable of handling light interrupted cuts, ensuring consistent process reliability across various CNC and conventional turning setups.
Special features
A standout characteristic of the RT250+ grade is its two-color CVD coating, which significantly simplifies visual wear detection. This practical feature allows operators to monitor the cutting edge and schedule insert changes precisely. Furthermore, the robust combination of geometry and carbide grade minimizes the risk of edge chipping under mechanical stress. Please note that these inserts are exclusively supplied in a packaging unit of 10 pieces.
