TNMG 220408 T9235 – Turning insert (ISO) by Tungaloy, CVD-coated carbide, 60° triangle

A TNMG 220408 turning insert designed for external and internal turning, featuring a CVD-coated carbide grade optimised for steel under lower cutting speeds and interrupted conditions

• CVD-coated carbide grade T9235
• 60° triangular ISO form TNMG
• 0.8 mm corner radius for versatile cuts
• Cylindrical hole and double-sided chipbreaker

Durable grade for unstable and interrupted turning

The CVD-coated carbide T9235 is formulated for steel machining where stability is limited or interruptions occur. Its toughness reduces chipping risk during impacts, so the cutting edge retains integrity even under variable conditions. This results in fewer unexpected indexings and a steadier production flow, supporting predictable tool life and less frequent tool changes. The combination of a robust grade and controlled chip formation prioritises process security and consistent component quality.

ISO compatibility and secure mounting for predictable performance

Built to ISO dimensions, the triangular form with a 60° included angle and a cylindrical hole ensures straightforward fitting in standard TNMG holders. Key seating parameters — form, clearance angle, tolerance class, fixation, size and thickness — determine compatibility; matching these avoids clamping errors and run-out. The 4.76 mm plate thickness and standard geometry support reliable mechanical clamping and repeatable positioning, which together reduce vibration and improve dimensional stability on the workpiece.

Improved chip control and versatile edge geometry

A double-sided chipbreaker combined with a 0.8 mm corner radius offers a balance between edge strength and surface finish. The chipbreaker promotes controlled evacuation on both cutting directions, reducing built-up edge and helping to maintain a consistent surface texture. The triangular TNMG shape provides multiple indexable edges, increasing effective cutting life per insert and lowering tooling cost per part in short- to medium-run production where occasional re-indexing is required.

Application guidance and selection for efficient machining

For turning in less stable set-ups and interrupted cuts, select the matching chipbreaker and the T9235 grade for its superior toughness at lower speeds. When adopting the insert into an existing process, confirm holder compatibility by cross-checking the TNMG220408 geometry, hole style and plate thickness. Metav Werkzeuge can advise on correct holder selection and assist with process parameters, ensuring that the insert’s properties translate into improved throughput and reduced scrap rates while keeping setup effort minimal.

FAQ

What materials is this insert suitable for?
The TNMG 220408 T9235 insert is designed primarily for steel machining; the CVD-coated carbide composition provides toughness for interrupted cuts and less stable conditions.

How is compatibility with holders determined?
Compatibility depends on form, free angle, tolerance class, fixation, size and thickness; confirm the TNMG geometry and 4.76 mm thickness against the holder specification before mounting.

Is the T9235 grade coated and what are the benefits?
Yes — the T9235 grade is CVD-coated carbide, which enhances wear resistance while retaining core toughness, improving reliability in interrupted or unstable turning operations.

How does the chipbreaker affect performance?
The double-sided chipbreaker promotes controlled chip formation on both cutting faces, aiding evacuation and reducing built-up edge for more consistent surface finish and reduced risk of edge failure.

How many usable edges does the triangular insert offer?
The triangular TNMG form provides multiple indexable cutting edges; combined with the double-sided chipbreaker, this increases the effective life and economy per insert.
