DNMG150404 T9235 Tungaloy turning insert — CVD‑coated carbide, 55° rhombic

The DNMG150404 T9235 Tungaloy turning insert is an ISO‑standard indexable insert for turning steel, designed for low cutting speeds and unstable or interrupted cuts.

• CVD‑coated carbide for improved wear resistance
• 55° rhombic shape for versatile turning applications
• Double‑sided chipbreaker for two usable cutting edges
• Cylindrical hole with screw fastening for secure clamping

Consistent performance in interrupted and unstable cuts

The CVD‑coated carbide grade T9235 is formulated for steel machining at lower cutting speeds and under less stable conditions. The coating increases surface hardness and thermal stability, which translates into longer tool life and fewer insert changes during production. In practice, this means fewer interruptions on the shop floor and more predictable cycle times when turning parts with interrupted cuts or variable support. The combination of substrate and coating helps maintain a stable cutting edge even when feeds fluctuate, delivering repeatable dimensional results.

Secure mounting and ISO compatibility for easy integration

The insert follows ISO conventions, so compatibility with holders is determined by form, clearance angle, tolerance class, fastening method, size and thickness. The rhombic 55° geometry and cylindrical hole ensure positive clamping with standard screw systems; the 4.76 mm thickness and 15 mm size provide robust support in the pocket. Because the plate is double‑sided, each insert offers two cutting edges, improving cost efficiency per edge compared with single‑edged solutions. Clear compatibility reduces setup time and simplifies tool inventory management on the shop floor.

Practical guidance for selection and application

Select the double‑sided chipbreaker variant and the T9235 grade when turning steel components with interrupted cuts or lower cutting speeds. The 0.4 mm corner radius provides a balance between edge strength and surface finish; increase radius for improved edge robustness or reduce it for finer profiles. For internal turning, ensure adequate rigidity of the tool assembly and select feed and speed parameters compatible with the grade’s low‑speed optimisation. Proper coolant and stable clamping further enhance chip control and surface consistency, reducing rework and scrap.

How this insert supports production reliability

Using an ISO‑standard insert such as this improves interchangeability across tool systems and supports efficient stocking. The DNMG150404 geometry and the Tungaloy grade offer a practical compromise between productivity and process security, particularly for steel applications where chip control is critical. The result is fewer tool‑related stoppages and a more stable production rhythm, aiding both planning and cost control in batch and jobbing environments.
