CNMM 160616 T9235 ISO turning indexable insert, rhombic 80° – Tungaloy

The CNMM 160616 T9235 is an ISO‑standard turning insert for external and internal turning, developed for steel applications under lower cutting speeds and unstable or interrupted conditions.

• ISO rhombic insert, 80° geometry
• CVD‑coated carbide grade T9235
• Single‑sided chipbreaker for interrupted cuts
• 6.35 mm thickness, 1.6 mm corner radius

Reliable cutting in interrupted and unstable turning conditions

The CNMM geometry with an 80° cutting edge and rhombic form delivers stable engagement for external and internal operations, reducing vibration in challenging set‑ups. The CVD‑coated carbide substrate (grade T9235) is a tough, wear‑resistant combination chosen specifically for steels at lower cutting speeds; this increases resistance to chipping when cuts are interrupted or when the machining environment is less rigid. The result is improved process stability and fewer unplanned tool changes, which supports continuous production and predictable cycle times.

Clear compatibility and system integration for quick tool selection

Compatibility with toolholders is determined by form, clearance angle, tolerance class, clamping method, size and thickness; the insert is delivered with a cylindrical hole for secure fastening. Specifying the ISO designation and dimensions simplifies the search for matching holders and clamping kits, ensuring a correct fit that maintains repeatable datum and runout control. Integrating the insert into a complete system — insert, suitable external holder or boring bar, shim/clamping set and replacement screws — ensures reliable mounting and repeatable performance across batches.

Precise edge preparation and geometry for surface quality and tool life

The one‑sided chipbreaker and a corner radius 1.6 mm balance edge strength and surface finish, allowing heavier interrupted cuts without premature edge failure. The 6.35 mm thickness contributes to rigidity at the cutting zone, while the 0° clearance angle suits conventional turning set‑ups and helps maintain a robust cutting edge. Together, these features reduce micro‑chipping and promote consistent surface finish on steel workpieces, lowering rework and inspection overhead.

Practical benefits for workshop and production planners

Selecting this insert helps reduce downtime associated with edge chipping and unplanned insert changes in unstable machining scenarios. The grade and chipformer are optimised for a broad range of steel grades and for operations where interrupted cuts are common, delivering a pragmatic mix of wear resistance and toughness. For procurement, the ISO designation and clear geometry data simplify stocking and spare‑part management while supporting process reproducibility on the shop floor.

FAQ

Is this insert suitable for interrupted cutting in steel?
The CNMM 160616 T9235 insert is specifically graded (T9235) and designed to cope with interrupted cuts in steel, offering enhanced toughness and resistance to chipping.

Which holders are compatible with the insert?
Compatibility depends on form, clearance angle, tolerance class, clamping and thickness; use the ISO designation CNMM160616 to find holders that match these parameters.

What benefits does the CVD coating provide?
The CVD coating on the T9235 grade increases wear resistance while the tough carbide substrate supports stable performance under lower cutting speeds and unstable conditions.

How does the corner radius affect performance?
A corner radius of 1.6 mm improves edge strength and helps maintain surface finish during heavier or interrupted cuts, reducing the risk of premature edge failure.

Can this insert be used for internal turning?
Yes, the insert’s geometry and ISO form permit both external and internal turning when matched with an appropriate boring bar or internal holder.
