TNMG 160408 T9205 TNMG turning insert – Tungaloy, CVD-coated carbide, 60°

The TNMG160408 T9205 is an ISO-standard triangular turning insert designed for productive external and internal turning in stable machining conditions.

• CVD-coated carbide grade T9205
• Suitable for productive steel turning
• 60° triangular geometry, 0.8 mm corner radius
• Double-sided chipbreaker with cylindrical hole

Durable wear resistance for longer tool life

The CVD-coated carbide in T9205 provides a wear-resistant surface that extends service intervals during continuous production. As a CVD-coated grade, the cutting edges resist abrasive wear and maintain dimensional stability at higher cutting speeds, which translates into fewer insert changes and more consistent component quality. The result is improved process efficiency and predictable tool-life behaviour under stable clamping and setup conditions.

Accurate geometry for repeatable turning results

The triangular 60° insert form with a 0.8 mm corner radius and a 0° clearance geometry ensures repeatable engagement and consistent cutting forces on the workpiece. Compatibility with the toolholder depends on form, clearance angle, tolerance class, clamping method, size and thickness; matching these parameters ensures secure seating and repeatable results. The ISO-standard format simplifies holder selection and inventory management, supporting fast changeovers and reliable machining tolerances.

Controlled chip formation and secure retention

A double-sided chipbreaker on this insert provides efficient chip control when paired with appropriate feeds and depths of cut, aiding surface quality and evacuation in turning operations. The cylindrical hole offers positive clamping and stable positioning in indexable holders, while the double-sided design doubles the number of usable cutting edges per insert, reducing tooling costs per part and supporting lean production workflows.

Optimised for steel and productive turning strategies

Designed primarily for machining steel, the grade and geometry combination supports productive turning where stability and repeatable edge performance are priorities. Selecting the correct chipbreaker and matching the insert to the workpiece rigidity and machining parameters will deliver the best combination of surface finish and productivity. For applications outside standard steel turning, a dedicated grade or geometry should be chosen to maintain process reliability.

FAQ

Which materials is this insert intended for?
The TNMG160408 T9205 insert is optimised for machining steel under stable conditions; the T9205 grade is a wear-resistant, CVD-coated carbide suited to productive turning.

How many cutting edges are available per insert?
With a double-sided triangular design, the insert provides multiple indexable edges, doubling usable edges compared with single-sided variants and improving cost efficiency.

What effect does the 0.8 mm corner radius have on the process?
A 0.8 mm corner radius offers a balance between edge strength and surface finish, reducing peak stresses while supporting moderate to heavier finishing passes when tool and workpiece rigidity are sufficient.

Is the insert compatible with standard ISO holders?
The insert follows ISO geometry; compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness — the TNMG160408 format is widely supported by ISO‑standard turning toolholders.

What benefits does the T9205 coating provide?
The T9205 CVD coating improves abrasive wear resistance and edge stability at higher cutting speeds, which supports longer tool life and consistent component quality in production turning.
