DNMG 150404 GH330 Turning Insert — ISO DNMG, 0.4 mm radius · Tungaloy

The DNMG150404 GH330 Tungaloy turning insert is an ISO-standard rhombic, cemented carbide indexable insert designed for external and internal turning applications where wear resistance and cutting-edge stability are required

• ISO DNMG150404 rhombic insert
• GH330 carbide grade for wear resistance
• 0.4 mm corner radius
• Double-sided chipbreaker design
• Cylindrical hole for secure clamping

Productivity gains through a wear‑resistant carbide grade

The combination of the GH330 Tungaloy grade with a compact rhombic geometry delivers measurable productivity improvements in turning operations. The cemented carbide substrate and GH330 formulation are geared towards a balance of wear resistance and edge stability, which reduces tool changes and keeps cycle times lower. Where process consistency is essential, this insert supports longer uninterrupted runs and contributes to overall cost efficiency by maintaining surface quality over extended tool life.

Secure clamping and straightforward holder compatibility

Designed as an ISO‑standard indexable insert, the ISO DNMG150404 form ensures predictable compatibility with matching DIN/ISO DNMG holders and boring bars. The cylindrical hole and specified plate thickness of 4.76 mm provide reliable mechanical clamping and repeatable seating in the pocket, reducing setup variation. For high‑stability turning, pairing the insert with the correct holder geometry, shim and torque for the replacement screw is essential to exploit its full performance potential.

Geometry tuned for surface integrity and reliable chip control

The rhombic DNMG shape combined with a 0.4 mm corner radius offers a compromise between robust cut‑edge strength and the ability to produce clean finishes on workpieces. The double-sided chipbreaker geometry supports effective chip control for many turning conditions when the chipbreaker is selected to suit the material and cutting mode. The specified 0° relief characteristic influences cut engagement and should be considered when setting feeds and depths to achieve the desired surface finish and dimensional accuracy.

System perspective and application guidance for turning

This insert forms part of a complete system: ISO indexable insert, suitable external holder or boring bar, a matching underlay/clamping set and the corresponding replacement screw. Application is primarily for turning, including both external and internal operations; the recommended practice is to choose the appropriate chipbreaker and grade based on the workpiece material, process stability and machining strategy. The DNMG150404 GH330 Tungaloy turning insert is therefore a practical choice where repeatable performance and consistent results are required.
