DNMG150412 AH6225 indexable turning insert by Tungaloy — PVD-coated carbide, 55° rhombic for turning

The DNMG150412 AH6225 is an ISO rhombic indexable insert designed for external and internal turning, offering a sharp yet stable cutting edge for variable machining conditions.

• PVD-coated carbide grade AH6225
• Universal for stainless steels
• Rhombic 55° geometry
• 1.2 mm nose radius
• Double-sided chipbreaker

Consistent cutting performance for stainless steels and mixed batches

The combination of a PVD coating and a wear-resistant carbide substrate delivers controlled flank wear and predictable edge behaviour during medium cutting operations. This results in a more consistent part finish and reduced risk of work hardening when machining stainless steels. The insert’s stable cutting edge helps maintain dimensional accuracy across batch changes, which supports a smoother production flow and fewer in-process adjustments.

Secure seat and ISO compatibility reduce setup time

Built to ISO dimensions, the rhombic insert ensures straightforward replacement in standard holders and boring bars. The cylindrical hole and standard tolerances allow fast clamping with an appropriate clamp and screw set, reducing downtime during tool changes. A clearly defined 55° lead angle improves access in shoulder and profiling operations while maintaining predictable cutting forces for stable toolholding.

Predictable chip control and longer tool life under varying conditions

The double-sided chipbreaker geometry is optimised for mid-range feeds and variable cutting conditions, assisting reliable chip formation and evacuation. The AH6225 grade balances sharpness and edge robustness, which contributes to longer productive time between indexings and reduces the frequency of insert changes. Fewer interruptions translate to better throughput and a lower effective tooling cost per component.

Practical benefits for workshop productivity

A 1.2 mm nose radius provides a compromise between edge strength and surface finish, suitable for many general turning tasks. The insert’s 4.76 mm thickness and 15 mm size conform to common ISO tooling systems, enabling flexibility across different toolholders and reducing the need for specialized inventory. The combination of these features supports reproducible results and predictable process windows in routine shopfloor use.
