DNMG 150612 T9205 — Turning indexable insert (ISO) by Tungaloy

DNMG150612 T9205 is an ISO-format indexable insert designed for productive external and internal turning of steel under stable machining conditions

• CVD-coated cemented carbide grade T9205
• Rhombic 55° insert geometry
• Double-sided chipbreaker for reduced inventory
• 1.2 mm corner radius, 6.35 mm plate thickness

Consistent productivity for steel turning

The combination of a CVD-coated cemented carbide substrate and the T9205 wear grade delivers a hard-wearing cutting edge tailored to higher cutting speeds in stable setups. The chemical vapour deposition (CVD) coating provides a uniform, hard surface layer that improves wear resistance and reduces flank wear during continuous turning of steel, resulting in longer intervals between index changes. For process planners this means fewer tool changes, more predictable cycle times and improved chip control when the correct chipbreaker and insert geometry are selected.

Secure seating and repeatable clamping for reliable cycles

Designed to ISO norms, the insert's cylindrical hole and defined tolerances permit precise seating in compatible holders and boring bars. The 6.35 mm plate thickness and adherence to ISO form and clearance specifications ensure a stable clamping interface, reducing chatter and vibration. As a result, reproducible part quality and consistent surface finish are achieved across batches, which supports efficient production planning and reduces scrap rates in serial turning operations.

Geometry that balances strength and surface quality

The rhombic 55° geometry combines accessibility for internal boring with the rigidity needed for external turning. The double-sided chipbreaker design allows use of both faces, improving inventory efficiency and lowering tooling costs per cutting edge. The 1.2 mm corner radius provides a compromise between edge strength and the ability to produce fine surface finishes; a larger radius increases edge robustness, while the chosen radius supports medium-depth finishing passes without sacrificing stability.

System integration and practical use in the workshop

The insert is supplied as part of a system comprising the ISO insert, a matching external holder or boring bar, and standard clamping elements and screws. Compatibility depends on form, clearance angle (0° free angle), tolerance class, mounting style and plate thickness, so selection of a matching holder is recommended. The DNMG150612 T9205 insert supports efficient tool management through reversible indexing and straightforward replacement, which reduces machine downtime and simplifies logistics for production lines.

FAQ

Is this insert suitable for both external and internal turning?
Yes. The rhombic 55° geometry and double-sided chipbreaker make the DNMG150612 T9205 insert suitable for both external and internal turning operations under stable machining conditions.

Which materials are recommended for this grade?
The T9205 CVD-coated grade is optimised for machining steel; it provides wear resistance and stable cutting at higher speeds when the workpiece and setup remain rigid.

Does the insert require a special holder?
The insert conforms to ISO dimensions; compatibility is ensured by matching holder form, clearance, tolerance class, mounting and thickness. A holder with an appropriate seat for a cylindrical-hole DNMG insert is required.

How does the double-sided chipbreaker help in production?
A double-sided chipbreaker allows both faces to be used, extending the number of usable cutting edges per insert and reducing tooling inventory and costs.

What are the key identifiers for ordering this item?
Order using article number 6785739 or SKU 6785739-Tungaloy to ensure the correct DNMG150612 T9205 turning insert is supplied.
