CNMG120408 T5105 CNMG ISO turning insert for Drehen by Tungaloy — CVD-coated carbide, 0.8 mm radius

CNMG120408 T5105 is an ISO-formatted indexable insert designed for external and internal turning in stable, high-speed conditions

• ISO-formatted rhombic insert
• CVD-coated carbide grade T5105
• 0.8 mm corner radius for robust cutting
• Suitable for external and internal turning

Predictable fit and fast changeovers that reduce downtime

The ISO standard geometry of this indexable insert guarantees repeatable seating and orientation in matching holders, since compatibility is defined by shape, clearance angle, tolerance class, clamping arrangement, size and thickness. Thanks to this standardisation, setup and tool changes are more reliable and faster, reducing machine idle time. Clear specification of CNMG120408 and its dimensions supports consistent tool inventory and traceability across turning centres.

Longer edge life for high-speed cast iron applications

The T5105 grade is a CVD-coated carbide optimised for the high-speed machining of cast iron under stable cutting conditions. The CVD coating provides a wear-resistant surface that improves flank life and maintains a stable cutting edge, which in turn helps to secure component quality and reduce the frequency of insert changes. For operations prioritising throughput and surface finish, this wear performance translates into lower cycle-time variability and predictable tool costs per part.

Geometry engineered for strength and surface quality

The rhombic form with an 80° main cutting angle, 0° clearance angle, 0.8 mm corner radius and 4.76 mm thickness offers a balance between cutting-edge robustness and accessible cutting action. A double-sided chipbreaker and the presence of a cylindrical hole permit secure clamping and reversible indexing for economical use of the insert faces. These geometric choices support steady chip formation and consistent surface finish on both external and internal turning operations, making the insert suitable for serial production where repeatability is essential.

FAQ

Which materials is this insert best suited to machine?
The CNMG120408 T5105 Tungaloy insert is optimised for cast iron machining and performs best under stable, high-speed cutting conditions.

How does the T5105 grade affect tool life?
The T5105 CVD-coated carbide provides enhanced wear resistance, which increases flank life and reduces frequency of insert changes in continuous turning processes.

Can the insert be used for both external and internal turning?
Yes, the rhombic geometry and secure clamping with the cylindrical hole make the insert suitable for both external and internal turning applications.

What does the 0.8 mm corner radius mean for component finish?
A 0.8 mm corner radius offers greater edge strength and contributes to consistent surface quality while resisting chipping in interrupted or continuous cuts.

How is the insert indexed and clamped?
The insert uses a central cylindrical hole for positive seating and a double-sided chipbreaker that allows reversible indexing to use both cutting edges.
