CNMG 090408 T5115 ISO turning insert by Tungaloy — CVD-coated cemented carbide, rhombic, with cylindrical hole for turning

CNMG090408 T5115 is an ISO-format turning insert designed for general-purpose external and internal turning, offering a balanced combination of wear resistance and edge stability.

• CVD-coated cemented carbide grade T5115
• Rhombic plate, 80° approach angle
• Double-sided chipbreaker for consistent chips
• Cylindrical hole, compatible with ISO holders

Consistent performance for cast-iron turning

The CNMG090408 is produced in a CVD-coated cemented carbide grade that is optimised for cast-iron machining, which provides a reliable balance between wear resistance and edge stability. The geometry—a rhombic plate with an 80° approach angle—delivers a robust cutting edge that reduces vibration in interrupted cuts and long overhangs. For engineers and shop managers, this means fewer tool changes and a steadier process, translating to higher throughput and predictable cycle times.

Easy selection and holder compatibility

Compatibility depends on form, clearance angle, tolerance class, fixing method, size and thickness; the plate’s 0° clearance angle and ISO format simplify matching with standard external holders and boring bars. The insert’s cylindrical centre hole enables secure clamping and repeatable seating, while the double-sided design allows indexing to a fresh edge without swapping insert types. This reduces inventory variety and simplifies tool management in production environments.

Chip control and surface finish benefits

The double-sided chipbreaker is engineered for controlled chip formation when turning cast iron, delivering consistent chip shapes that aid automated chip evacuation and protect the workpiece finish. Where surface quality matters, the combination of a stable cutting edge and the CVD coating helps achieve reliable results with reduced need for finishing passes. For operations seeking dependable parts per shift, this geometry supports steady productivity.

Durability, process security and economical machining

The CVD-coated grade T5115 emphasises long tool life under typical cast-iron conditions while maintaining edge robustness during moderate interruptions. The insert’s corner radius 0.8 mm supports a compromise between strength and form fidelity for common turning profiles. Selecting a suitably rated insert and maintaining consistent clamping ensures lower downtime and a favourable cost-per-part ratio over extended production runs.

FAQ

What materials is this insert suitable for?
The CNMG090408 T5115 insert is specified as a universal grade for cast iron; its CVD-coated cemented carbide composition and chipbreaker geometry are optimised for reliable machining of cast-iron workpieces.

How does the double-sided chipbreaker benefit production?
A double-sided chipbreaker allows the insert to be indexed to a second cutting edge, enabling longer service life per insert and consistent chip control for safer automated machining.

Which holder types are compatible with this insert?
Compatibility is determined by form, clearance angle, tolerance class, fixing and plate size; the ISO format and cylindrical hole permit use with standard ISO external holders and appropriate boring bars designed for CNMG plates.

What are the key dimensional values to check before fitting?
Verify the plate thickness (4.76 mm), corner radius (0.8 mm), approach angle (80°) and clearance angle (0°) against the holder specifications to ensure correct seating and secure clamping.

Can this insert be used for internal turning?
Yes, the geometry and chip control features make the insert suitable for both external and internal turning operations when paired with the correct toolholder.
