• ISO‑standard CNMG 120412 indexable insert
• CVD‑coated carbide grade T9215
• Double‑sided chipbreaker, cylindrical hole
• Optimised for medium steel turning

Reliable productivity for medium‑steel turning

The CVD‑coated cemented carbide grade T9215 is designed to balance wear resistance with breakage toughness, making it a dependable choice for sustained production runs. As an ISO‑compliant indexable insert, the component supports stable cutting conditions and predictable tool life, which reduces unscheduled tool changes and improves machine utilisation. The coating improves resistance to flank and crater wear during extended engagements, so cycle times remain consistent and scrap rates are reduced.

Secure seating and simple integration into tool systems

With the rhombic CNMG geometry and an 80° principal cutting angle, the insert offers a versatile cutting edge for both external and internal turning; compatibility with holders is ensured by standardised form, size and thickness specifications. The insert’s cylindrical hole and standard clamping interfaces enable reliable positioning and repeatable seating in matched toolholders and boring bars, minimising vibration and promoting repeatable part tolerances. This straightforward integration supports shorter setup times and predictable process repeatability.

Controlled chip formation and improved surface finish

The double‑sided chipbreaker is tuned for medium‑steel applications and promotes consistent chip control across a range of feeds and depths. Effective chip formation reduces the risk of entanglement and protects the workpiece surface, contributing to improved surface quality and reducing the need for secondary finishing. In applications with light interruptions the geometry maintains edge stability, which supports machining at higher material removal rates without compromising finish.

Practical selection and process advantages

Selection of a grade such as T9215 allows manufacturers to favour a single insert family for varied turning tasks, lowering inventory complexity and easing tool management. The combination of ISO standard form factor, defined 1.2 mm nose radius and 0° clearance angle supports predictable toolpath planning and predictable part outcomes. For operations seeking a balance of productivity and tool life, this insert offers a pragmatic solution that reduces downtime and supports stable batch processing.
