CNMG 120412 AH6235 Tungaloy turning insert — PVD-coated carbide, 1.2 mm radius, 80°

The CNMG 120412 AH6235 is an ISO-standard rhombic turning insert designed for external and internal turning, optimised for stainless steels and interrupted cuts.

• PVD-coated carbide grade AH6235
• Optimised for stainless steels and interrupted cuts
• Rhombic CNMG geometry, 80° cutting angle
• 1.2 mm corner radius, double-sided chipbreaker

Increased productivity in stainless-steel turning

The combination of a PVD-coated surface and the AH6235 carbide grade delivers a balance of wear resistance and toughness that suits demanding tasks on stainless steels and conditions with frequent interruptions. The coating reduces flank wear at elevated temperatures while the tougher substrate resists chipping during unstable cuts, resulting in more consistent tool life and fewer indexings. This translates into measurable productivity gains when paired with appropriate feeds and stable setups, especially where tool-change downtime is costly.

Secure mounting and dimensional reliability for repeatable results

ISO conformity and the rhombic CNMG form ensure wide compatibility with established holders; the cylindrical-hole design supports reliable clamping and accurate seat location. The 80° geometry and 0° clearance combine to deliver predictable cutting forces, while the 4.76 mm plate thickness and precise tolerance classes contribute to vibration damping and stable machining. The double-sided configuration increases usable edges per insert and reduces tooling cost per component, supporting repeatable surface finishes and cycle-time stability.

Practical guidance for tool selection and cutting strategy

Select the chipbreaker and insert grade to match workpiece stability and the nature of the cut: the double-sided chipbreaker is suited to general turning on less stable set-ups, while the 1.2 mm corner radius provides a stronger cutting edge for heavier depths of cut but requires slightly higher feed to maintain surface quality. The rhombic form factor and cylindrical hole facilitate quick index changes and straightforward mounting in ISO holders. For interrupted cuts or components with risk of breakout, the AH6235 combination of toughness and wear resistance is particularly effective, reducing flank and corner failures when the setup is correctly matched.

FAQ

What materials is this insert suitable for?
The CNMG 120412 AH6235 insert from Tungaloy is designed primarily for stainless steels and other alloys where toughness and chip control are required, and it performs well in interrupted cutting conditions.

Can this insert be used on both external and internal turning operations?
Yes, the ISO CNMG geometry and the rhombic form make the insert suitable for both external and internal turning when combined with an appropriate holder and correct cutting parameters.

How does the 1.2 mm corner radius affect machining?
A 1.2 mm corner radius on the insert increases edge strength, permitting higher depths of cut and improved resistance to chipping, while typically requiring a slightly higher feed to maintain surface finish.

Is the insert indexable on both sides and does that reduce tooling costs?
The insert is double-sided with a chipbreaker on both faces, allowing multiple re-indexings and reducing the cost per effective cutting edge compared with single-sided solutions.

What makes AH6235 different from standard grades?
The AH6235 grade is a PVD-coated carbide designed with enhanced toughness for applications on stainless steel and areas prone to breakout; the coating improves wear resistance while the substrate resists fracture under interrupted conditions.
