DNMG150408 AH6225 Tungaloy indexable turning insert — ISO 150408, 55° rhombic

The DNMG150408 AH6225 is an ISO‑standard indexable turning insert designed for external and internal turning, optimised for medium machining of stainless steels and mixed production conditions.

• PVD-coated carbide grade AH6225
• 55° rhombic geometry for versatile turning
• 0° clearance angle for secure cutting
• Double-sided chipbreaker, with cylindrical hole

Consistent cutting performance for stainless steels and mixed materials

The combination of a PVD‑coated surface and a wear‑resistant carbide substrate gives the insert stable performance under varying conditions. As a universal grade for stainless steels, the AH6225 formulation balances edge sharpness and toughness to reduce built‑up edge and maintain dimensional accuracy during medium finishing and light roughing. For production planning, this means fewer interruptions for tool changes and a predictable surface finish on turned components.

Stable edge, predictable chip control, improved productivity

A well‑designed double‑sided chipbreaker promotes reliable chip formation and evacuation, which reduces rework and improves cycle times. The geometry provides a sharp yet stable cutting edge, allowing efficient heat dissipation and consistent cutting forces. For operations where surface integrity and repeatability matter, this insert supports smoother machine cycles and longer effective tool life, helping to lower overall machining costs over a production run.

Clear compatibility and secure clamping for reliable setup

Belonging to the ISO turning insert series, compatibility with a holder depends on form, clearance angle, tolerance class, fastening method, size and thickness. The insert’s cylindrical hole and standard rhombic form make it straightforward to seat in many ISO‑type external holders and boring bars. When selecting a holder, match the 55° geometry, thickness and tolerance to ensure secure clamping and correct cutting position; correctly matched components reduce vibration and support consistent part accuracy.

Practical selection advice for process stability

Choose the AH6225 grade and the included chipbreaker when the job requires a balance between finish and robustness, particularly for stainless steels or mixed batches where conditions change. The 0.8 mm corner radius suits medium feeds where edge strength is needed without compromising surface quality. For uncertain applications or to optimise cutting parameters, consult technical documentation or request application support to fine‑tune speeds and feeds for the specific material and machine setup.
