TNMG 160408 T9225 TNMG insert for turning by Tungaloy — CVD‑coated carbide, 60°

TNMG160408 T9225 is a triangular, ISO‑design turning insert engineered for external and internal turning where toughness and stable chip control are required.

• CVD‑coated carbide grade T9225
• Triangular 60° geometry with 0.8 mm radius
• Double‑sided insert for economical indexing
• Cylindrical hole, 4.76 mm thickness

Consistent cutting performance for changing conditions

The combination of a CVD‑coated carbide matrix and the T9225 grade delivers a balance of hardness and toughness tailored to medium to heavy steel machining. The coating enhances wear resistance while the substrate provides impact strength, which helps maintain tool life under slightly interrupted cuts or variable engagement. This results in predictable component quality and fewer unexpected insert changes, supporting continuous production runs and efficient use of machine time.

Economical handling and repeatable edge life

The triangular geometry and double‑sided configuration enable multiple indexings, reducing tooling cost per part and simplifying inventory. With a 4.76 mm thickness and a 0° relief angle, the insert provides stable clamping and rigidity in the holder, helping to minimise vibration and improve surface finish. The insert’s construction allows straightforward seating in ISO‑compliant toolholders and fast rotation to a fresh edge, which supports lean tool management and short changeover cycles.

ISO compatibility and quick selection for the workshop

Designed as an ISO‑specified turning insert, the part conforms to standard dimensions and tolerances that determine compatibility by form, relief angle, fastening and thickness. The cylindrical hole and standard seat make it compatible with many ISO TNMG holders when the holder matches the insert form and size. Selecting a matching chipbreaker and the T9225 grade according to the workpiece material and machining strategy ensures stable chip formation and process reliability.

Practical machining notes and recommended use cases

The insert’s 0.8 mm corner radius offers a compromise between edge strength and finer detail capability, suitable for general turning and finishing passes on steel components. The double‑sided chipbreaker supports consistent chip control across a range of cutting depths; choose the chipbreaker style and cutting parameters that align with component geometry and machine rigidity. Further application data and machining recommendations are available so that the insert can be matched precisely to holder geometry and process requirements.

FAQ

Which toolholders fit this TNMG insert?
Compatibility requires a holder matching the TNMG form, the ISO size 160408, thickness 4.76 mm and the correct clamping for a cylindrical hole; the TNMG160408 T9225 insert fits holders built for TNMG‑160408 inserts.

Is the insert suitable for interrupted cuts?
Yes, the T9225 CVD‑coated carbide grade is a robust universal grade designed for medium to heavy steel and offers additional toughness for slightly interrupted cuts.

How many usable edges does each insert provide?
The triangular, double‑sided design provides multiple indexable edges; each side can be indexed according to the holder’s seating and clamping method for economical edge use.

Which operations are recommended for this insert?
Intended for external and internal turning, the TNMG160408 T9225 insert performs well for roughing and finishing in steel where a balance of wear resistance and toughness is required.

How does the 0.8 mm corner radius influence the operation?
A 0.8 mm radius increases edge strength and reduces chipping risk while offering a good compromise between robustness and surface finish capability.
