TNMG 160408 T9225 indexable turning insert (ISO TNMG160408) by Tungaloy — CVD-coated carbide, 0.8 mm radius

The TNMG160408 T9225 is an ISO-standard triangular indexable insert designed for external and internal turning in medium-to-heavy steel applications, offering robust performance under varying engagement conditions.

• CVD-coated carbide grade T9225
• ISO TNMG 160408 triangular insert
• 0.8 mm corner radius for robust cutting
• Double-sided chipbreaker and central hole

Consistent cutting performance for medium-to-heavy steel turning

The CVD-coated carbide composition of this insert is formulated to balance wear resistance and toughness. The T9225 grade excels in situations with variable engagements or slightly interrupted cuts, delivering stable cutting performance and extended tool life compared with uncoated grades. The combination of coating and substrate reduces flank wear and supports predictable tool change intervals, which helps to keep machining cycles efficient and repeatable.

Faster indexability and lower downtime

A triangular, double-sided insert design provides multiple cutting edges per part, enabling rapid indexing and reduced tooling costs over time. The central cylindrical hole and standardised form make clamping secure and repeatable in ISO holders, so changeovers are straightforward and tactile. Reduced downtime during insert changes directly improves productivity and supports tighter production schedules on turning centres and lathes.

Geometry engineered for stability and surface quality

With a 0.8 mm corner radius and a 60° seat angle, the insert offers a compromise between edge strength and the ability to achieve fine surface finishes. The modest radius absorbs cutting shocks and improves edge life during heavier depths of cut, while the seating angle and triangular shape contribute to consistent chip formation. The double-sided chipbreaker aids efficient chip control for typical steel machining operations, assisting in maintaining surface integrity and process stability.

Compatibility, selection and application advice

Compatibility with toolholders depends on form, clearance angle, tolerance class, fastening method, size and thickness; the ISO designation ensures broad compatibility with standard TNMG turning holders. The insert is best used for steel turning where robustness is required—select the T9225 grade when encountering mixed engagement conditions or mildly interrupted cuts. For tailored cutting data and optimal holder pairing, Metav Werkzeuge can provide application-specific recommendations based on machine rigidity and part geometry.

FAQ

What materials is this insert suitable for?
The TNMG160408 T9225 insert is optimised for steel machining, particularly medium-to-heavy turning where a balance of wear resistance and toughness is required.

Is this insert indexable and reversible?
Yes, the triangular indexable insert is double-sided, offering multiple usable cutting edges for economical use and straightforward indexing.

How does the T9225 grade cope with interrupted cuts?
The T9225 grade is formulated to provide additional toughness for slightly interrupted cuts and variable engagement conditions, improving edge security under shock loads.

Which holder characteristics determine compatibility?
Compatibility requires matching the insert form, clearance angle, tolerance class, fastening method, size and thickness to the holder; the ISO designation simplifies this process for standard TNMG holders.

What are the key dimensions to check before ordering?
Confirm the ISO designation TNMG160408, insert size 16 mm, thickness 4.76 mm, corner radius 0.8 mm and the 60° seating angle to ensure the insert fits the intended holder and application.
