DNMG 150412 T9215 — Turning insert (ISO DNMG150412) by Tungaloy

DNMG150412 T9215 is an ISO‑standard rhombic turning insert designed for productive external and internal turning in medium steel applications.

• CVD‑coated carbide grade T9215
• Optimised for medium steel machining
• 55° rhombic geometry, 1.2 mm corner radius
• Double‑sided chipbreaker, cylindrical hole

Boosted productivity through material and coating

The combination of a CVD‑coated carbide substrate and the T9215 grade delivers a reliable balance of wear resistance and toughness for continuous to slightly interrupted cuts. The coating reduces flank wear and extends tool life under stable cutting conditions, which translates into fewer insert changes and higher machine uptime. For production environments the result is a measurable increase in throughput while retaining surface quality on steel components.

Stable geometry for predictable cutting performance

The 55° rhombic geometry with a 1.2 mm corner radius supports robust engagement during turning operations and helps absorb shock loads at entry points. The double‑sided chipbreaker is designed to form and control chips consistently, improving evacuation in both external and internal profiles. The 0° clearance angle and standardised ISO shape ensure repeatable seating and clamping accuracy when paired with compatible ISO holders, reducing set‑up time and variation between batches.

Simple integration with ISO tool systems

This indexable insert is produced to ISO dimensions, compatible by form, clearance, tolerance grade, fastening and thickness with standard turning holders and boring bars. The cylindrical hole and standard thickness of 4.76 mm permit secure fastening and straightforward replacement of worn inserts without additional machining of the holder. Specifying ISO‑compliant components simplifies inventory management and ensures interchangeability across machines and workshops.

Grade selection and application guidance

The T9215 grade is recommended as a first choice for medium steel machining, combining resistance to abrasive wear with reduced risk of chipping. When selecting this insert, match the chipbreaker and grade to workpiece material, machining stability and desired surface finish. For heavier interrupted cuts or hard inclusions, consider adapting cutting parameters or choosing a more fracture‑resistant grade; for fine finishing, reduce feed and maintain appropriate cutting speed to benefit from the coating's wear characteristics.

FAQ

What materials is this insert suited for?
The DNMG150412 T9215 insert is designed primarily for medium steel machining and is optimised to combine wear resistance with fracture toughness for productive turning.

How does the T9215 grade affect tool life?
The T9215 CVD coating improves resistance to abrasive wear while maintaining a tough substrate, which increases life under continuous or lightly interrupted cutting conditions.

Which holder types are compatible with the insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening and insert thickness; the insert follows ISO dimensions and fits ISO‑compliant turning holders and boring bars.

Is the insert reversible or single‑use?
This indexable insert is double‑sided, allowing rotation to a second cutting edge when the active edge reaches the end of its service life.

What are the key dimensions to check before ordering?
Check the ISO designation (DNMG150412), corner radius (1.2 mm), thickness (4.76 mm) and the 55° included angle to ensure correct seating and performance.
