TNMG160408 T9205 ISO turning insert for steel — Tungaloy, CVD-coated carbide, double-sided chipbreaker

The TNMG160408 T9205 is an ISO-indexable turning insert engineered for productive external and internal turning of steel, offering a wear-resistant CVD coating and a geometry suited to stable machining conditions.

• CVD-coated carbide for high wear resistance
• Double-sided chipbreaker for two cutting edges
• 0.8 mm corner radius for reliable finishing
• 4.76 mm thickness for increased rigidity

Built for productive steel turning

The combination of CVD-coated surfaces and a wear-resistant T9205 grade carbide provides improved abrasion resistance and consistent edge life under elevated cutting speeds. This design reduces flank and crater wear, which in turn supports predictable tool-change intervals and lower machining costs per component. The substrate and coating synergy enable a controlled break-in behaviour, so the machining process maintains a consistent surface finish and repeatable dimensional accuracy across batches.

Secure clamping and precise geometry for stable cuts

An ISO triangular insert with a 60° included angle and a triangular form gives a compact, rigid seat in compatible holders; the cylindrical hole ensures positive clamping with standard screws and pads. The 0.8 mm corner radius supports reliable finishing passes while the 4.76 mm thickness increases resistance to deflection in interrupted cuts. The double-sided chipbreaker provides two usable edges per indexation, extending productive edge life and reducing tooling costs. The combination of features makes the insert a robust choice where fixture stability and repeatable tool positioning are required.

Application guidance to maximise process security

Designed for turning under stable conditions, the insert excels in medium to high cutting speeds when mounted in a suitable rigid holder or boring bar as part of a complete indexable system. The chip control characteristics suit a range of steel grades when paired with appropriate coolant and feed settings; select the chipbreaker and grade to match workpiece material and setup rigidity. For internal and external turning operations the insert supports predictable wear patterns and efficient swarf evacuation, helping to sustain cycle-time targets and reduce rework rates. Technical advisers are available to recommend optimal holder pairings and cutting parameters for specific production needs.

FAQ

What materials is this insert best suited for?
The TNMG160408 T9205 insert is formulated for productive machining of steel; the T9205 grade and CVD-coated surface deliver abrasion resistance and consistent performance in stable turning operations.

How many usable edges does the insert provide?
With its double-sided chipbreaker and triangular geometry, the insert offers multiple indexable edges, extending usable life before a replacement is required.

What should be considered when selecting a holder?
Holder compatibility depends on form, relief angle, tolerance class, clamping method, size and thickness; select a rigid ISO-compatible external holder or boring bar that matches the insert's cylindrical hole and 60° geometry.

Can this insert be used for finishing passes?
Yes; the 0.8 mm corner radius and stable geometry make the insert suitable for finishing and semi-finishing when mounted in a sufficiently rigid setup.
