CNMM250924 T9235 ISO rhombic indexable turning insert — Tungaloy

CNMM250924 T9235 is an ISO-form indexable insert for external and internal turning, engineered for steel machining where interrupted cuts or unstable conditions require a tough, reliable grade.

• CVD-coated carbide grade T9235
• ISO rhombic CNMM250924 80° geometry
• 2.4 mm corner radius for robust engagement
• Single-sided chipbreaker, cylindrical hole

Consistent cutting in unstable turning conditions

The CNMM250924 insert combines a CVD-coated surface with a cemented carbide substrate to deliver toughness where chip formation is unpredictable. The T9235 grade is formulated for steel at moderated cutting speeds and excels when the cut is intermittent or the setup lacks rigidity. Choosing a tougher grade reduces edge chipping and unplanned stoppages, which in turn improves throughput and lowers rework rates. The result is a more predictable machining process and fewer scrap parts.

Strong edge and secure clamping for repeatable results

With an 80° rhombic geometry and a 2.4 mm corner radius, the insert provides an enlarged edge zone that tolerates heavier engagement and sudden load changes. The insert’s 9.52 mm thickness increases support in the pocket and, together with the cylindrical hole, ensures secure clamping in standard ISO holders. These features contribute to repeatable dimensional accuracy and a longer effective tool life, reducing downtime for insert changes and adjustment.

Improved chip control and application range

The single-sided chipbreaker is tuned to the grade and typical steel applications, promoting reliable chip segmentation under varying feeds and depths of cut. This aids evacuation in both external and internal turning operations and reduces the risk of chip entanglement. The combination of grade, chip control geometry and substrate makes this insert suitable for unstable setups, repair work and batch production where robustness matters more than maximum cutting speed.

System compatibility and practical guidance

The insert is part of an ISO series and is compatible with holders that match its shape, clearance angle, tolerance class, fastening method, size and thickness. When integrating the insert into a tool system, select a holder and clamping kit rated for rhombic CNMM geometry and verify pocket support to exploit the insert’s stiffness. For applications requiring different cutting regimes, alternative grades or chipbreaker variants can be considered to balance surface finish and productivity.

FAQ

What materials is this insert intended for? The CNMM250924 T9235 insert is intended primarily for steel machining; the T9235 grade is optimised for tougher conditions and interrupted cuts in steel.

How does the chipbreaker affect machining performance? The single-sided chipbreaker on this insert improves chip segmentation and evacuation during turning operations, helping maintain stable cutting when the setup vibrates or cuts are interrupted.

Is the insert compatible with standard ISO CNMM holders? Yes, the insert follows the ISO CNMM form; compatibility depends on matching the holder to the insert’s shape, relief angle, tolerance and thickness.

What benefit does the 2.4 mm corner radius provide? A 2.4 mm corner radius increases edge strength and allows more robust engagement, reducing the likelihood of brittle edge failure during heavy or interrupted cuts.

Which features support secure clamping and repeatability? The combination of 9.52 mm thickness, the cylindrical central hole and ISO rhombic geometry provides enhanced pocket support and secure clamping for repeatable positional stability.
