DNMG150404 T9225 — ISO turning insert for medium‑to‑heavy steel turning by Tungaloy

The DNMG150404 T9225 is an ISO‑standard indexable insert designed for external and internal turning operations where interrupted cuts or variable engagement demand additional toughness and stable cutting performance.

• CVD-coated carbide grade T9225
• Rhombic shape with 55° cutting angle
• 0.4 mm corner radius for edge strength
• Double-sided chipbreaker with cylindrical hole

Reliable cutting performance under variable conditions

The combination of a CVD‑coated surface and a carbide substrate delivers wear resistance and toughness for demanding turning tasks. The rhombic 55° geometry supports versatile approach angles, while the 0.4 mm corner radius increases edge robustness for mid‑to‑heavy axial depths. Thanks to the T9225 grade’s formulation, the insert offers stable performance during light interruptions and changing cut conditions, reducing the need for frequent edge changes and supporting continuous production.

Designed for secure mounting and economical use

ISO compatibility ensures straightforward integration with standard holders, but proper matching requires consideration of form, clearance angle, tolerance class, fastening and dimensions. The insert is double‑sided and indexable, providing economical use through two cutting edges per side. The cylindrical hole and a plate thickness of 4.76 mm contribute to secure clamping and axial stability, while the 15 mm inscribed circle keeps the insert compact for both external and internal assemblies. The nominal clearance angle of 0° must be matched to the holder specification to ensure correct chipflow and contact geometry.

Coating, material and recommended applications

A CVD coating on a high‑performance tungsten carbide body enhances thermal stability and abrasion resistance, making this grade particularly suitable for medium‑to‑heavy steel machining. The geometry and chipbreaker design support effective chip control; however, selection of the exact chipbreaker version should follow workpiece material, cutting data and machine rigidity. This insert is intended for turning operations where repeatable results and durable cutting edges are required, offering a balance of productivity and tool life for general steel turning tasks.
