DNMG150408 T9215 ISO indexable turning insert for turning — Tungaloy

The DNMG150408 T9215 is an ISO‑standard indexable turning insert designed for external and internal turning, offering a balance of wear resistance and fracture toughness for medium‑range steel machining.

• CVD-coated carbide for high wear resistance
• Optimised for medium steel machining
• Double-sided chipbreaker for consistent chips
• Rhombic DNMG form with 0.8 mm nose radius

Productivity through a wear-resistant CVD coating

The combination of a CVD-coated carbide substrate and the T9215 grade provides a clear productivity advantage in continuous and light interrupted turning. The coating increases abrasive wear resistance while the carbide core maintains fracture toughness, which reduces unplanned insert changes and keeps cycle times low. For production environments seeking steady tool life and repeatable component quality, this grade supports higher cutting speeds and longer machining intervals, translating into measurable process gains.

Predictable chip control and consistent surface finish

A double-sided chipbreaker integrated into a rhombic geometry delivers reliable chip formation and evacuation, which simplifies coolant and chip‑conveyor setup. The controlled chip flow lowers the risk of secondary machining marks and helps achieve consistent surface quality on medium steels. The insert’s 0.8 mm nose radius aids in producing stable finishes while maintaining dimensional control, particularly on external profiles and light shoulder cuts.

Compatibility with ISO toolholders and easy indexability

The insert conforms to ISO DNMG dimensions and is designed for use with standard DNMG holders; compatibility depends on form, clearance angle, tolerance class, fixing method, size and thickness. The 0° clearance angle and rhombic DNMG form permit reliable seating and simple indexing, enabling quick rotation to fresh cutting edges and minimising downtime. Selection of a matching holder and correct clamp hardware ensures repeatable positioning and optimal cutting geometry.

Application guidance and material suitability

The grade is intended as a first choice for medium steel machining, combining stable wear behaviour with resistance to chipping under normal to slightly interrupted cuts. It is suitable for both external and internal turning operations when paired with an appropriate holder and cutting parameters. For machining strategies that demand higher productivity with predictable tool life, the insert’s design supports consistent cycle throughput and fewer tool interventions.
