CNMG 120412 T9235 Turning indexable insert by Tungaloy — CVD-coated carbide, 1.2 mm corner radius

The CNMG120412 T9235 is an ISO‑standard turning insert designed for external and internal turning applications where interrupted cuts or unstable setups demand a tough, damage-resistant grade.

• ISO CNMG 120412 format for standard holders
• CVD-coated carbide grade T9235 for steel
• 1.2 mm corner radius for robust edge strength
• Double-sided chipbreaker with cylindrical hole

Consistent cutting under unstable conditions

The insert’s CVD-coated carbide grade T9235 is formulated to deliver toughness rather than maximum hardness, making it suitable for steel machining at moderate cutting speeds and where interrupted cuts occur. The coating improves wear resistance and helps maintain a stable cutting edge during variable engagement. For production environments with occasional chatter or varying clamping stiffness, this composition reduces the risk of premature edge chipping and supports repeatable component quality.

Fast changeover and secure clamping for increased uptime

As an ISO CNMG 120412 format, the indexable insert fits a wide range of standard external holders. Compatibility is governed by the insert’s shape, clearance angle, tolerance class, fastening method, size and thickness — the defined geometry allows predictable seating and repeatable positioning. The cylindrical hole and matching clamp hardware provide a secure mounting interface, so tool changes are rapid and downtimes are minimised, contributing to a more efficient workflow on the shop floor.

Edge geometry engineered for productivity and chip control

A 1.2 mm corner radius offers a compromise between edge strength and finishing capability: it increases robustness for roughing passes while still permitting acceptable surface quality on many turning operations. The double-sided chipbreaker provides two usable cutting edges per side, effectively extending tool life and lowering cost per edge. The 4.76 mm plate thickness contributes to insert rigidity, reducing vibration sensitivity and enabling steadier cutting forces for consistent dimensional results.

Practical guidance for application and selection

Select the CNMG120412 T9235 when machining unalloyed or low‑alloy steels under less-than-ideal stability or where interrupted cutting is expected. Match the chipbreaker and grade to the workpiece material and cutting conditions: a tougher grade at lower cutting speeds often outperforms harder grades in terms of reliability under shock loads. When in doubt, consult the insert’s system composition — holder, shim and clamping set — to ensure optimal force transmission and edge support.

FAQ

What materials is this insert suitable for? The CNMG120412 T9235 insert is intended primarily for steel machining; the T9235 CVD-coated carbide grade is optimised for tougher performance in steel at moderate cutting speeds.

How does the chipbreaker influence cutting results? The double-sided chipbreaker on the CNMG120412 helps control chip shape and evacuation, improving surface finish and tool life in interrupted or unstable cuts.

How many usable cutting edges are available per insert? With a double-sided design and the rhombic CNMG format, the insert offers multiple usable edges, effectively extending service life before replacement.

Which holders are compatible with this insert? Any external or internal holder designed for the ISO CNMG 120412 format will be compatible, provided the holder matches the insert’s clamp style, size and tolerance class.

What are the key dimensional specifications to check before fitting? Confirm the insert size (12 mm), thickness (4.76 mm), corner radius (1.2 mm) and the 80° included angle to ensure correct fit and performance.
