CNMG 090404 T9215 – Indexable turning insert for turning, CVD-coated cemented carbide (Tungaloy)

A CNMG090404 T9215 is an ISO‑standard rhombic indexable insert designed for external and internal turning, optimised for medium‑hard steel where high wear resistance and fracture toughness are required.

• CVD-coated carbide for medium steel
• Double-sided chipbreaker design
• 0.4 mm corner radius for versatility
• ISO rhombic CNMG form with 80° lead angle

High productivity and wear resistance for medium‑steel turning

The T9215 grade offers a balanced combination of wear resistance and fracture toughness, making it a reliable choice for continuous to slightly interrupted cuts in medium‑hard steel. The CVD coating extends tool life by reducing flank wear, which in turn increases uptime and reduces tooling changes. Because the grade was developed for productivity, cycle times are shortened without sacrificing surface finish or process stability, yielding a lower tool cost per part in high‑volume turning.

Secure mounting and predictable geometry for consistent results

The CNMG rhombic form with an 80° lead angle and a cylindrical central hole provides straightforward clamping and predictable cutting geometry. Compatibility with holders depends on insert form, clearance angle, tolerance class, fastening and thickness; the standardised ISO geometry ensures interchangeability across compliant tool holders. The 0° clearance angle and 0.4 mm corner radius give a favourable balance between edge strength and versatility, supporting both roughing and finishing passes when combined with the correct feed and depth of cut.

Practical selection: chipbreaker, grade and process benefits

The double‑sided chipbreaker reduces chip length and improves evacuation in turning, especially useful when machining long, slender components or when coolant access is limited. Selecting T9215 helps maintain a stable cutting edge under higher material removal rates; this reduces the risk of premature chipping and contributes to reproducible part quality. For customers requiring guidance, choosing the matching holder and setting cutting data according to machine rigidity will maximise the grade’s productive potential while maintaining surface integrity.
