CNMG 090404 T9215 turning insert – CVD-coated carbide, 0.4 mm radius (Tungaloy)

CNMG 090404 T9215 is an ISO-format indexable turning insert designed for efficient external and internal turning in medium-steel applications

• CVD-coated carbide grade T9215
• 0.4 mm corner radius for precise contours
• 80° rhombic geometry for versatile turning
• Double-sided with cylindrical centre hole

More machining per edge: productivity and wear control

The CVD-coated carbide composition of this grade offers a balanced combination of wear resistance and fracture toughness, allowing consistent chip formation and extended tool life during continuous to slightly interrupted turning. For mid-range steel workpieces, the turning grade T9215 delivers higher material removal rates while maintaining dimensional stability; the result is reduced spindle downtime and improved process economy. This benefit is particularly relevant where repetitive runs demand repeatable performance and predictable edge life.

Secure clamping and ISO compatibility for fast tool changes

Built to the ISO series format, the insert’s 80° rhombic geometry and cylindrical centre hole ensure reliable positioning and clamping in standard toolholders. Compatibility with holders depends on form, relief angle, tolerance class, fastening, size and thickness, which simplifies tool selection across existing setups. The double-sided design supports reversible indexing, reducing tooling costs and spare inventory while enabling quick edge changes to maintain cycle-time efficiency.

Surface quality and process robustness

A 0.4 mm corner radius provides a precise cutting edge for finishing contours and controlled surface finish, while the chipbreaker geometry supports consistent chip evacuation. For production environments seeking reproducible quality, the combination of grade and insert geometry reduces the risk of workpiece scrapping and minimises rework. When machining medium steels, the insert performs well at elevated feeds and cutting speeds, contributing to overall productivity gains and stable component tolerances.

Practical selection advice and application scope

This insert is suited for external and internal turning of medium steels; choose the appropriate chipbreaker and grade variant according to the workpiece material, cutting strategy and machine stability. The indexable plate is part of an ISO system that includes matching external holders, boring bars, seat pads and clamping kits; using the correct holder geometry and fastening method is essential to exploit the T9215 grade fully and to achieve repeatable results in high-volume production.
