TNMM160408-57 T9225 TNMM 160408 turning insert, CVD-coated carbide, 60° (Tungaloy)

TNMM160408-57 T9225 is an ISO-standard indexable insert designed for medium to heavy turning applications, offering robust edge strength and reliable chip control in variable cutting conditions.

• Robust CVD-coated carbide for medium to heavy turning
• 60° triangular geometry for versatile toolholder fit
• Cylindrical hole for secure clamp mounting
• 0.8 mm corner radius for improved edge strength

Optimised cutting performance for demanding turning tasks

The TNMM160408-57 T9225 insert combines a CVD-coated surface with a tough carbide substrate to deliver predictable performance when machining steel under mixed conditions. The T9225 grade is formulated for high stability and good wear resistance, which translates into fewer tool changes and steadier cycle times. Chip formation is controlled by the integrated chipbreaker, reducing the risk of re-cutting and facilitating automated swarf removal. This technical combination supports continuous production where interrupted cuts or variable engagement demand extra toughness.

Secure seating and precise geometry for stable production

A triangular insert with a 60° lead angle and a cylindrical hole offers a repeatable clamping interface that reduces vibration and runout in the toolholder. Compatibility with a holder depends on form, relief angle, tolerance class, fastening method, size and thickness; selecting a matching 60° holder and appropriate clamping set ensures the intended performance. The insert's 0° relief and ISO conformity permit straightforward replacement in standard external and internal turning tool systems, fostering predictable tool life and part quality in serial production.

Extended tool life and process economy through design choices

The 0.8 mm corner radius increases edge robustness for heavier depths of cut while the CVD-coated surface improves resistance to abrasive wear and built-up edge when machining alloyed and plain steels. These attributes reduce downtime associated with frequent index changes and support a better cost-in-use ratio across medium-to-long production runs. The dedicated chipbreaker (designation 57) is tuned for steady chip flow in the intended material range, which helps to maintain consistent surface finish and minimise secondary operations.

Practical guidance for application and handling

As an ISO indexable insert intended for turning, the TNMM160408-57 performs best when matched to the correct holder geometry and clamping torque; a secure clamping set and correct screw specification are essential for repeatable results. Choose the T9225 grade and chipbreaker combination according to workpiece material, machine rigidity and feed rate to balance wear and cutting forces. For those working across component families, this insert offers a versatile solution that simplifies inventory while delivering dependable performance in both external and internal turning operations.

FAQ

What materials is this insert suitable for?
The TNMM160408-57 T9225 insert is optimised for steel machining and performs well in medium to heavy turning of alloyed and plain steels, thanks to its T9225 CVD-coated carbide grade.

Which holders are compatible with this triangular insert?
Compatibility depends on holder form, relief angle and tolerance class; the 60° geometry of this triangular insert is compatible with standard 60° turning holders that accept ISO TNMM-form inserts.

How does the chipbreaker designation affect performance?
The chipbreaker 57 is designed for controlled chip formation under the intended feed and depth-of-cut ranges, improving swarf evacuation and surface finish when using the T9225 grade in turning operations.

Is the insert supplied with a through-hole for clamping?
Yes — the insert is supplied with a cylindrical hole for secure clamping and repeatable seating in compatible clamping sets.

Can this insert be used for interrupted cuts?
The T9225 grade provides enhanced toughness, making the insert suitable for applications with light interruption or variable engagement where a more robust edge is required.
