DNMG 150408 T9215 ISO turning insert for turning — Tungaloy

The DNMG150408 T9215 is an ISO rhombic turning insert designed for external and internal turning, offering a wear-resistant grade for medium steel machining.

• CVD-coated carbide for high wear resistance
• Optimised for medium steel with T9215 grade
• Rhombic 55° geometry, 0° clearance angle
• Double-sided insert with cylindrical hole

Greater productivity through a wear-resistant grade

The T9215 grade is a CVD-coated carbide specifically developed as a first choice for medium steel machining. By combining elevated wear resistance with fracture toughness, the grade supports continuous to slightly interrupted cuts and allows longer tool life and fewer indexings. The result is improved productivity and predictable performance in batch production, where component consistency and uptime are critical.

Stable geometry for accurate, repeatable results

The rhombic 55° geometry and 0° clearance deliver a balance between cutting edge strength and accessibility in shoulder and profile turning. A 0.8 mm corner radius reduces edge stress while supporting dimensional accuracy on workpieces. Holder compatibility is determined by form, free angle, tolerance class, fastening, size and thickness, so correct seat and clamp selection ensure consistent clamping and repeatable tolerances for serial production.

System efficiency with easy indexing and secure clamping

As a double-sided ISO insert with a cylindrical hole, this design enables fast indexing and stable clamping on matched external holders or boring bars. The 4.76 mm plate thickness and 15 mm size provide robustness for general turning applications, while the rhombic profile offers access in internal bores and external shoulders. The system build—insert, suitable holder, shim/clamping set and spare screw—supports quick tool changes and lower effective tooling cost per part.

Practical guidance for reliable machining

Select the appropriate chipbreaker and T9215 grade according to the workpiece material and cutting mode; the double-sided chipbreaker here is suited for typical medium-steel feeds and speeds. For slightly interrupted cuts choose a more conservative depth of cut and verify clamping torque to maintain edge stability. For application-specific cutting data or to adapt parameters for different steels and spindle speeds, Metav Werkzeuge can provide technical recommendations to reduce trial time and secure process reliability.

FAQ

What materials is this insert suitable for?
The DNMG150408 T9215 insert is optimised for medium steel applications; the T9215 CVD-coated carbide grade balances wear resistance and edge strength for consistent performance.

How is the insert secured in the holder?
Clamping is achieved via the cylindrical hole and the appropriate shim/clamping set; correct seating per the ISO form and proper fastening ensure stable fixation for the turning operation.

Is the insert indexable and economical for serial production?
Yes, the double-sided design enables indexing to a fresh cutting edge, reducing tooling cost per part and improving uptime in serial production scenarios.

What does the 55° geometry mean for cutting?
A 55° rhombic geometry provides an effective compromise between cutting-edge strength and access to shoulders and profiles, offering predictable cutting forces and good surface finish on typical turning tasks.

What is the manufacturer SKU and article number for ordering?
The manufacturer SKU is TUN6772268 and the article number is 6772268; reference these when specifying the Tungaloy DNMG150408 T9215 insert.
