TNMG 220408 T9235 — Triangle Turning Insert for Turning, Tungaloy

The TNMG220408 T9235 is a triangular indexable turning insert designed for general turning of steel, offering a robust CVD-coated carbide grade for interrupted cuts and unstable operating conditions

• CVD-coated carbide grade T9235
• Double-sided chipbreaker for chip control
• Triangle 60° insert with 0.8 mm radius
• ISO-compatible design for standard holders

Stable machining in interrupted and unstable conditions

The combination of a CVD-coated carbide substrate with the T9235 grade produces a tougher cutting edge that performs under lower cutting speeds and interrupted cuts. This construction increases resistance to chipping and thermal stress, which is particularly valuable when stability is limited in the set-up. The chip control geometry reduces the likelihood of entangling swarf and ensures more predictable evacuation, translating to fewer interruptions and steadier cycle times. In practical terms, operators benefit from extended edge life and reduced rework when machining steel components under variable conditions.

Efficient inventory and economical indexing

The triangular 60° geometry together with a 0.8 mm corner radius and a central cylindrical hole make the insert straightforward to seat and index in ISO holders. As a multi-edge indexable insert, it allows several reuses of the same piece before disposal, lowering per-edge costs and simplifying stock management. The double-sided chipbreaker enables consistent cutting performance on both sides and supports quick rotation to a fresh cutting edge, which reduces downtime during production runs. For workshops aiming to streamline tooling logistics, this design offers a clear balance of efficiency and cost control.

Practical integration into machining systems

Selection of the appropriate chipbreaker and grade should match the workpiece material, the chosen cutting strategy and machine stability; in this context, the insert is part of an ISO turning insert system that includes the matching external holder or boring bar, a shim or clamping kit and replacement screws. Correct matching is determined by insert form, clearance angle, tolerance class, fixation method, size and thickness. This modular approach simplifies tooling changes and ensures the insert works as intended when paired with compatible ISO-standard holders; technical advisors can assist with holder choice and recommended cutting parameters for specific setups.

FAQ

What materials is this insert suitable for? The TNMG220408 T9235 is specified for machining steel and performs well in conditions with interrupted cuts or limited stability due to its tougher CVD-coated carbide grade.

How does the chipbreaker affect performance? A double-sided chipbreaker on the insert improves chip control, reduces entanglement and helps maintain consistent surface quality during turning operations.

Is the insert compatible with ISO holders? Yes, the insert follows ISO turning insert conventions; compatibility depends on insert form, clearance angle, tolerance class, fixation, size and thickness when matching a holder or boring bar.

How many cutting edges can be used before disposal? Being a triangular, indexable insert, the component offers multiple usable edges; the exact number depends on the machining conditions and edge wear observed with the T9235 grade.

What mounting style does the insert require? The insert features a cylindrical hole and is secured using the appropriate clamping kit and screws as part of the ISO insert system; correct torque and a matching shim/clamping set are recommended.
