TNMG 220408 T9235 Tungaloy turning insert – ISO TNMG triangular, CVD-coated carbide, 60°

The TNMG220408 T9235 is a triangular ISO indexable insert for external and internal turning, engineered for steel machining under interrupted or unstable cutting conditions.

• CVD-coated carbide grade T9235 for steel machining
• Triangular 60° ISO geometry, 0° relief
• Cylindrical hole for secure insert clamping
• Double-sided chipbreaker for efficient chip control

High machining reliability with optimised cutting grade

The insert combines a CVD-coated carbide substrate with the T9235 grade to deliver a balance of toughness and wear resistance tailored for steel applications. This composition is specifically suited to lower cutting speeds and conditions where the cut is interrupted or the setup lacks rigidity. The double-sided chipbreaker reduces burrs and stabilises chip flow, which in turn lowers the risk of unexpected tool failure and supports consistent surface quality on components.

Process stability and simple integration into ISO systems

Built to ISO dimensions, the insert's 60° triangular form and 0° relief allow straightforward integration with standard external holders or boring bars. The cylindrical hole and defined seating tolerances ensure secure clamping and repeatable positioning, reducing setup variability. The 0.8 mm corner radius provides a compromise between edge strength and finish quality, enabling predictable component tolerances with less rework and improved cycle-time consistency.

Cost-effective stock and predictable life in production

As a double-sided insert, the turning cutter reduces stocking requirements and provides two usable cutting edges before replacement, offering economical tool usage in batch and continuous production. The CVD coating enhances resistance to abrasive wear while the carbide core maintains edge robustness in interrupted operations, resulting in fewer tool changes and less unplanned downtime during turning tasks.

Application support and selection guidance

When selecting a chipbreaker and grade for a specific turning task, consider workpiece material, rigidity of the setup and desired surface finish; the T9235 grade is a practical choice where toughness and stable chip control are priorities. For guidance on holder compatibility, clamping torque or to match the insert to a given machining strategy, Metav Werkzeuge provides technical advice and application recommendations to aid process optimisation.

FAQ

What materials is this insert intended for? The TNMG220408 T9235 insert is designed primarily for steel machining and performs well under interrupted cuts and less rigid setups.

Is the insert single- or double-sided, and what are the implications? This is a double-sided insert; each face provides a cutting edge, which reduces stocking needs and extends the usable life per insert compared with single-sided alternatives.

How does the CVD coating influence performance? The CVD-coated carbide construction of the T9235 grade improves abrasive wear resistance while retaining edge strength, offering longer life in steel turning operations with varying cutting conditions.

Which holders are compatible with the ISO TNMG220408 geometry? Compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness; the ISO TNMG geometry ensures compatibility with standard TNMG external and internal turning holders when these parameters match
