TNMG 160412 T9235 Turning indexable insert — Tungaloy, CVD‑coated carbide, 60° triangular

A TNMG160412 T9235 Tungaloy triangular indexable insert engineered for general turning, offering robust chip control and reliable performance in unstable cuts and interrupted operations

• CVD‑coated carbide grade T9235
• Triangular 60° form, 16 mm inscribed circle
• 1.2 mm corner radius for stable contours
• Double‑sided chipbreaker with cylindrical hole

Stable cutting for interrupted and unstable turning

The insert offers a CVD‑coated carbide grade (T9235) designed as a tough option for steel machining where lower cutting speeds or unstable setups are necessary. The material combination promotes stable edge life under shock and interruption, while the coating supports resistance to abrasive wear. This results in fewer unexpected edge failures and more predictable tool changes, which supports consistent production output in small to medium batch turning operations.

Geometry that maintains dimensional control and surface finish

The triangular 60° geometry with a 16 mm inscribed circle provides a balance between accessibility and rigidity for external and internal turning. The 1.2 mm corner radius reduces groove wear and helps maintain component contours when machining interrupted profiles. The double‑sided configuration extends usable cutting edges per insert, improving process economy without compromising repeatability or accuracy on turned workpieces.

Chip control and holder compatibility for reliable set‑ups

A double‑sided chipbreaker combined with a cylindrical hole secures firm clamping and consistent chip formation across varying depths of cut. The insert is ISO‑standardised, so compatibility with an appropriate external holder or boring bar depends on matching form, clearance angle, tolerance class, fixing method, size and thickness. Selecting the correct seat and clamp ensures the chipformer performs as intended and reduces the likelihood of vibration or poor chip evacuation.

Practical benefits for workshop efficiency

Using a tough, coated grade in combination with a stable insert geometry reduces the frequency of tool interventions and improves uptime. The ISO conformity simplifies tool procurement and replacement across different holders and brands, while the twin‑edged design reduces tooling costs per machined part. These practical benefits make the insert suitable for jobbing shops and production cells where interrupted cuts, variable setups and mixed batch sizes are common.

FAQ

What materials is this insert suitable for?
The TNMG160412 T9235 Tungaloy insert is intended primarily for machining steel and is formulated as a tough grade for operations with lower cutting speeds, unstable setups or interrupted cuts.

How does the T9235 grade affect tool life?
The T9235 CVD‑coated carbide offers enhanced resistance to flank and crater wear under shock, which tends to extend usable edge life in discontinuous turning compared with harder, more brittle grades.

Which holder features must be checked for compatibility?
Compatibility requires matching the insert form, clearance angle (0°), tolerance class, fixing style, inscribed circle (16 mm) and thickness (4.76 mm) with the chosen external holder or boring bar.

Can the insert be used for internal boring as well as external turning?
Yes — the triangular 60° form and the cylindrical hole allow secure clamping in suitable boring bars as well as external turning holders, provided the holder is designed for TNMG‑type inserts.

How many usable edges does the insert provide?
As a double‑sided triangular insert, multiple cutting edges are available; rotating to a fresh edge restores cutting geometry and helps maintain process continuity.
