TNMG220404 AH6235 turning insert — Tungaloy, PVD-coated carbide, triangular 22 mm

The TNMG220404 AH6235 is an ISO-standard triangular turning insert designed for external and internal turning operations, optimised for stainless steels and interrupted cuts.

• PVD-coated AH6235 carbide grade
• Triangular TNMG 22 mm insert, 0.4 mm radius
• Double-sided chipbreaker, with cylindrical hole
• ISO-standard for external and internal turning

Consistent performance on stainless steels and difficult alloys

The PVD-coated AH6235 carbide grade delivers a balance between toughness and wear resistance, making it particularly suited to stainless steel machining and operations with frequent interruptions. The coating reduces built-up edge and improves tool life under variable cutting conditions, while the substrate toughness helps resist chipping during hard-to-cut passes. This results in fewer insert changes and more predictable process windows, which supports higher machine utilisation and lower overall tooling costs.

Secure clamping and precise geometry for repeatable results

The triangular plate form with a 0° clearance and a 60° wedge angle provides a stable cutting edge and predictable engagement in the holder. The insert’s 0.4 mm corner radius and standard 22 mm seat ensure compatibility with ISO holders when form, clearance, tolerance class, fastening and thickness are matched. The cylindrical hole enables reliable fastening and positional accuracy, reducing vibration and promoting consistent surface finish when used in the correct holder system.

Efficient chip control and application flexibility

Equipped with a double-sided chipbreaker, this insert supports controlled chip formation for external and internal turning, reducing the risk of tangling and improving operator safety. The combination of grade and chipbreaker suits interrupted cuts and tasks with higher breakout risk; choosing this cutting geometry and PVD coating helps maintain edge integrity and surface quality, particularly in production environments where repeatability and uptime matter.

Selection guidance and practical advantages for shops

When selecting the insert, match the grade and chipbreaker to the workpiece material and the machine’s rigidity. The PVD-coated carbide construction is advantageous for demanding stainless-steel jobs, while the triangular shape offers three usable edges per side for economical usage. For integration into existing tool systems, confirm holder compatibility by checking form, free angle, tolerance class, fastening type, size and thickness to avoid misfits and to preserve the achieved performance benefits.

FAQ

Which materials is this insert suitable for?
The AH6235-grade insert is optimised for stainless steel and is intended for applications with interrupted cuts or higher breakout risk; the combination of PVD coating and a tough substrate supports these materials.

What type of chip control does the insert offer?
The double-sided chipbreaker provides controlled chip formation for both external and internal turning, improving evacuation and surface quality when used with appropriate cutting parameters.

How many usable cutting edges are available on the insert?
As a triangular, double-sided plate, the insert provides multiple usable edges; the exact count depends on whether both sides are indexed, but the geometry is designed for economical edge utilisation.

Is the insert compatible with ISO toolholders?
Yes. The TNMG220404 follows ISO dimensions and compatibility is determined by matching form, clearance, tolerance class, fastening, size and thickness with the chosen holder.

What advantages does the PVD coating bring?
The PVD coating reduces adhesive wear and built-up edge, enhancing surface finish and insert life in stainless-steel applications while maintaining the substrate’s resistance to chipping.
