TNMG 160408 T9235 ISO turning insert — CVD-coated carbide, 0.8 mm corner radius (Tungaloy)

A TNMG160408 T9235 triangular indexable insert engineered for external and internal turning of steel, offering a tough CVD-coated carbide grade for interrupted cuts and less stable machining conditions.

• CVD-coated carbide for tough steel applications
• 0.8 mm corner radius for reliable edge strength
• ISO TNMG 160408 format with cylindrical hole

Consistent performance where interrupted cuts occur

The CVD-coated carbide grade T9235 is formulated for steel machining at moderate cutting speeds and where stability is limited. Its combination of substrate and coating enhances resistance to chipping during impact events, so the insert maintains a usable cutting edge longer under interrupted or unstable conditions. The 0.8 mm corner radius increases edge robustness and contributes to predictable tool life, while the double-sided design extends usage by allowing indexation of both cutting edges. These characteristics make the insert particularly suitable for workshop and production environments where part interruptions or variable clamping stability are common.

Seamless integration into ISO turning systems

Compatibility is determined by insert form, clearance angle, tolerance class, clamping method, size and thickness; the ISO designation and format facilitate selection of a matching holder or boring bar. The triangular TNMG160408 geometry with a 60° included angle and a cylindrical hole is widely supported across external holders and boring systems, simplifying tool assembly. The plate thickness of 4.76 mm and the 16 mm inscribed circle size align with standard TNMG tool families, enabling fast replacement and minimal setup time. Where process reliability is vital, matching the insert to an appropriate holder and clamp ensures repeatable seat and consistent cutting positions.

Practical benefits for productivity and process stability

Using a grade targeted at tougher steels and intermittent cuts reduces unscheduled downtime from edge failure and lowers the frequency of tool changes. The double-sided chipbreaker geometry offers two usable cutting edges per side, improving cost efficiency per insert. Additionally, the CVD coating supports thermal resistance and maintains a stable cutting edge under fluctuating temperatures, contributing to surface finish consistency and predictable component tolerances. For production managers and process engineers, these attributes translate into measurable throughput and fewer scrap parts when machining challenging steel batches.

Selection guidance and application notes

When selecting an insert for a turning operation, priority should be given to matching the grade and chipbreaker to the material and cutting conditions. The T9235 grade is recommended where lower cutting speeds and interrupted cuts are expected; for steady high-speed finishing a different grade would be more appropriate. Attention to clamping and holder rigidity remains critical: the insert delivers best results when mounted in a correctly specified TNMG-compatible holder and when machine-tool rigidity supports the intended cut. The system concept—insert, holder, shim and clamping set—should be considered holistically to exploit the insert’s full potential.

FAQ

What materials is this insert best suited for?
The T9235 grade is optimised for machining steel, especially where interrupted cuts or lower cutting speeds are expected; the insert is specified as a turning insert for steel applications.

How does the TNMG160408 format affect holder selection?
Holder compatibility depends on the TNMG form, clearance angle, tolerance and clamping; select a TNMG-compatible external holder or boring bar matching the TNMG160408 geometry and the 4.76 mm thickness.

Is the insert indexable on both sides?
Yes, the triangular TNMG design is double-sided, providing multiple usable edges and enabling indexation to extend service life.

What role does the 0.8 mm corner radius play?
The 0.8 mm corner radius increases edge strength and reduces susceptibility to chipping during interrupted cuts, improving process reliability in roughing or unstable clamping situations.

Does the T9235 grade require special cutting speeds?
T9235 is intended for lower to moderate cutting speeds in steel; choose speeds and feeds consistent with the grade recommendation and the rigidity of the machine-holding system to balance tool life and productivity.
