CNMG 160612 AH6235 Tungaloy Turning Insert — CNMG160612, PVD-coated carbide, 80° rhombic

A CNMG160612 AH6235 indexable turning insert designed for machining stainless steels and interrupted cuts, compatible with ISO-standard holders and modular turning systems

• PVD-coated AH6235 grade for toughness and wear resistance
• 80° rhombic geometry for stable external and internal turning
• 1.2 mm nose radius for balanced strength and finish
• Double-sided chipbreaker for extended insert life

Outstanding performance for demanding stainless-steel turning

The combination of a PVD-coated surface and the AH6235 tough carbide substrate delivers a balance between wear resistance and fracture toughness, specifically engineered for stainless steel and operations with increased breakout risk. This results in more consistent process behaviour under interrupted cuts and variable chip loads. The treated surface reduces built-up edge and improves tool life, while the substrate maintains edge integrity when encountering workpiece variability.

Precise geometry reduces vibrations and setup time

An ISO-conforming rhombic shape with an 80° geometry ensures predictable engagement with the workpiece and good support in standard turning holders. The cylindrical hole and standard seat dimensions make the insert straightforward to mount in compatible toolholders; compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness. The standardised geometry simplifies inventory and holder selection for production environments.

Improved process reliability and surface quality

A 1.2 mm radius provides a robust cutting point that balances surface finish and edge strength, reducing premature chipping when machining tough alloys. The double-sided chipbreaker aids in controlled chip formation, lowering the risk of tangles and facilitating efficient chip evacuation. These features support higher metal removal rates with predictable tool wear, contributing to improved throughput and fewer unscheduled tool changes.

Practical integration into indexable systems and toolrooms

The insert is part of an ISO turn insert series and forms an indexable system together with a compatible external holder, shim/clamp set and fastening screws. Its specification supports both external and internal turning operations; the selection of chipbreaker and grade should match the workpiece material and operation stability. For application matching, Metav Werkzeuge offers technical consulting and material-specific recommendations to ensure the insert is deployed where it performs best.

FAQ

Is this insert suitable for machining stainless steel?
The CNMG160612 AH6235 Tungaloy insert is specifically designed for stainless steel applications and interrupted cuts, offering improved fracture resistance and stable chip control.

Which holders fit this insert?
Holders that accept CNMG-style inserts with an 80° rhombic seat and a cylindrical mounting hole are compatible; ensure the holder matches the insert thickness, size and tolerance class.

What is the nose radius and why does it matter?
This insert has a 1.2 mm nose radius; that radius provides a compromise between strength and surface finish, reducing the likelihood of chipping while maintaining good workpiece quality.

Is the chipbreaker single- or double-sided?
The insert features a double-sided chipbreaker, allowing index rotation and extended life before reconditioning or replacement.

What coating and substrate does the insert have?
The grade is AH6235, a PVD-coated carbide formulation chosen for toughness and resistance to thermal and mechanical stresses in demanding turning operations.

Can this insert be used for both external and internal turning?
Yes; the rhombic geometry and ISO-standard dimensions make it suitable for both external and internal turning when used with an appropriate holder and setup.
