DNMG150612 AH6225 Tungaloy indexable insert — ISO turning insert for rostfreier Stahl, PVD-coated carbide

DNMG150612 AH6225 Tungaloy insert is an ISO‑standard indexable turning insert designed for external and internal turning, offering a 55° rhombic geometry and a stable cutting edge for medium machining conditions

• ISO rhombic 55° geometry
• PVD-coated carbide grade AH6225
• 1.2 mm corner radius for secure edge
• Double-sided chipbreaker with cylindrical hole

Reliable performance for rostfreier Stahl machining

The AH6225 grade is designed as a universal option for machining rostfreier Stahl, balancing a sharp cutting edge with the mechanical stability required for variable conditions. The combination of a PVD-coated carbide substrate and a precisely formed cutting edge reduces flank wear and maintains dimensional accuracy over longer tool life. For production planners this means fewer insert changes, reduced downtime and a more predictable process window when moving between batch sizes or mixed-series machining.

Geometry that stabilises cutting and improves surface quality

The 55° rhombic geometry and 1.2 mm corner radius deliver a favourable contact angle and controlled chip flow, while the integrated chipbreaker reduces the tendency for long, stringy chips in interrupted cuts. A 0° clearance angle and the rhombic platform provide consistent seating and repeatable cutting forces, which lowers vibration and enhances surface finish. These geometric choices translate directly into higher first-pass yield and less rework for turned components.

Coating and substrate for repeatable tool life

A carbide substrate combined with a PVD coating gives a hard, wear‑resistant surface that tolerates the abrasion and heat typical of medium finishing operations. The coating supports a stable cutting edge and improved oxidation resistance at raised temperatures, contributing to consistent performance across shifts and tool batches. This material and coating pairing supports a predictable replacement interval, which simplifies tool management and cost forecasts in industrial environments.

System compatibility and secure clamping for operational ease

The insert is manufactured to ISO dimensions so compatibility with holders is determined by form, relief angle, tolerance class, attachment method, size and thickness. The design includes a cylindrical hole for secure fastening and a double-sided layout that provides economical indexability. In practice this means straightforward integration into existing toolholders, simple inventory handling and quick exchange routines, supporting lean production workflows and minimal setup effort.

FAQ

Which materials is this insert best suited for?
The DNMG150612 AH6225 Tungaloy insert is optimised for rostfreier Stahl and performs reliably in medium finishing and mixed‑condition machining.

How does the AH6225 grade affect tool life?
AH6225 offers a PVD surface on a carbide substrate, which increases wear resistance and helps to maintain a sharp cutting edge for consistent tool life and repeatability.

Is the insert compatible with standard ISO holders?
Yes, the insert is made to ISO dimensions and fits holders that match the form, relief angle and clamping specifications for DNMG inserts.

What benefits does the 1.2 mm corner radius provide?
A 1.2 mm corner radius gives a robust edge for secure cutting, reducing the risk of chipping while improving surface finish in production turning.
