DNMG150404 T9225 turning insert — Tungaloy, ISO turning insert for robust steel machining

DNMG150404 T9225 is an ISO‑format rhombic turning insert optimised for external and internal turning in demanding steel applications.

• CVD-coated carbide grade T9225
• Robust for medium-to-heavy steel turning
• 55° rhombic form with cylindrical hole
• Double-sided chipbreaker, 0.4 mm radius

Engineered for process reliability and consistent chip formation

The CVD-coated carbide construction of this insert combines a wear‑resistant ceramic layer with a tough substrate to balance life and edge strength. As a universal grade T9225, the cutting material is designed for medium‑to‑heavy steel machining where variable cutting conditions or lightly interrupted cuts demand additional toughness. The integrated double-sided chipbreaker promotes controlled chip breaking across a range of feeds, reducing the risk of snarled chips and improving cycle reliability. Compatibility with appropriate toolholders is determined by form, 0° clearance angle, tolerance class, attachment method, size and thickness, ensuring predictable performance when paired with a correctly specified external holder or boring bar.

Geometry and dimensions that support productivity and surface quality

The rhombic 55° form delivers versatile approach angles for both facing and turning tasks while the 0.4 mm corner radius helps sustain edge strength under higher loads and contributes to a stable surface finish. The insert’s 4.76 mm thickness and the presence of a cylindrical hole for secure fastening increase clamping stability, which in turn reduces vibration and extends tool life. These geometry choices translate directly into fewer interruptions on the shop floor and more consistent part tolerances, making the component suitable for production environments where repeatability and throughput are priorities.

Practical system considerations and economical operation

System setup comprises the ISO turn insert, a matching outer holder or boring bar, a clamping pad/kit and spare screws; correct selection prevents premature wear and ensures safe engagement. The grade’s balance of wear resistance and toughness supports longer intervals between insert changes, improving cost per part in serial production. Backing from Tungaloy engineering provides confidence in material behaviour under varied cutting conditions, and documented compatibility with standard ISO holders simplifies procurement and inventory management.
