DNMG150416 AH6235 Tungaloy indexable insert for turning — PVD-coated cemented carbide, 55° rhombic

The DNMG150416 AH6235 Tungaloy is an ISO-standard rhombic indexable insert designed for external and internal turning, developed for stainless steels and interrupted cuts.

• PVD-coated cemented carbide AH6235
• Suitable for stainless steels and interrupted cuts
• ISO DNMG 150416 rhombic 55° insert
• Double-sided chipbreaker, cylindrical hole
• Corner radius 1.6 mm, 4.76 mm thickness

Engineered for reliable turning of stainless steels

The insert uses a PVD-coated cemented carbide grade AH6235, selected for a tougher cutting-edge performance where stainless steels tend to work-harden and cause edge chipping. The PVD coating enhances adhesion resistance and heat protection, which translates into a more consistent tool life under the stresses of interrupted cuts. Specified as ISO DNMG150416, the geometry offers a balanced approach between strength and accessibility on external profiles, helping to keep machining cycles predictable and downtimes low.

Predictable chip control and fewer interruptions

With a double-sided chipbreaker and a carefully matched geometry, the insert improves chip formation and evacuation. A chipbreaker shapes and breaks the chips into manageable segments, reducing the risk of entanglement and tool damage; this is especially important when machining stainless steels or working with variable fixtures. The insert’s corner radius 1.6 mm helps absorb cutting forces and delivers steadier cutting conditions, resulting in improved surface finish and fewer unexpected tool changes during production runs.

Straightforward integration into existing toolholders

The DNMG format conforms to ISO standards, which simplifies compatibility checks: form, relief angle and size determine fit rather than manufacturer-specific features. The rhombic 55° presentation combined with a cylindrical hole allows secure clamping in standard DNMG-capable holders and boring bars. The plate thickness of 4.76 mm and the 55° approach angle support robust clamping and favourable load distribution, reducing vibration and enhancing process reliability in both external and internal turning set-ups.

Application advantages and operational guidance

This grade is tailored for operations with increased breakout risk and for interrupted cuts where tougher grades extend service intervals. The insert performs well where stable chip control and a reliable cutting edge are required, such as in batch production of components in stainless steels. Selection of the correct holder, cutting parameters and coolant strategy will further extend performance; the geometry and PVD coating together contribute to consistent results and lower overall machining costs through fewer index changes.

FAQ

What materials is this insert best suited to machine? The DNMG150416 AH6235 Tungaloy insert is optimised for stainless steels and other work-hardened materials, offering improved resistance to edge chipping in interrupted cuts.

Is the DNMG150416 compatible with standard DNMG toolholders? Yes, the insert follows ISO DNMG dimensions and fits holders designed for DNMG150416 geometry, provided form, clearance and thickness match the holder specifications.

How does the AH6235 grade affect tool life? The AH6235 grade combines toughness and a PVD surface layer to reduce edge breakage and thermal wear, which typically results in longer usable life under interrupted or unstable cutting conditions.

What is the purpose of the double-sided chipbreaker? The double-sided chipbreaker shapes chips for controlled evacuation, reducing the risk of chip re-cutting and tool damage; this yields steadier cutting and fewer process interruptions.

Can this insert be used for both external and internal turning? Yes, the rhombic 55° geometry and cylindrical-hole clamping make the insert suitable for both external profiling and internal operations where DNMG inserts are applicable.
