CNMG 120404 T9235 turning indexable insert — CVD-coated carbide, 0.4 mm radius (Tungaloy)

The CNMG120404 T9235 is an ISO-standard rhombic indexable insert for external and internal turning, designed for steel machining with reliable chip control in unstable cutting conditions

• ISO CNMG 120404 form, rhombic geometry
• CVD-coated carbide grade T9235 for steel
• Double-sided chipbreaker for interrupted cuts
• 0.4 mm nose radius with cylindrical hole

Longer tool life and consistent performance for tougher turning jobs

The CVD-coated composition of this insert provides a hard, wear-resistant surface on a tough substrate, balancing edge protection with resistance to fracture. As a consequence, the T9235 grade is optimised for steel at moderate cutting speeds and in situations with variable stability, delivering longer tool life and fewer insert changes. The rhombic geometry combined with the double-sided chipbreaker helps to maintain controlled chip formation during both external and internal turning, reducing cycle interruptions and improving overall process reliability.

Precise form and compatibility reduce setup time

Conformance to the ISO CNMG 120404 specification ensures predictable fitment and repeatable results across standard holders. Key dimensional details — including the 0.4 mm nose radius, 4.76 mm thickness and the with cylindrical hole feature — simplify fixture selection and clamping. Clear specification of form, clearance angle and tolerance class enables straightforward matching with existing tooling systems, which shortens machine downtime and supports faster changeovers. This insert is therefore suitable where consistent geometry and straightforward replacement are priorities.

Practical advantages for challenging and interrupted cuts

When facing interrupted cuts or unstable workholding, impact resistance and chip evacuation are decisive. The combination of a tough carbide substrate and a protective CVD coating offers enhanced chip resistance, while the double-sided chipbreaker promotes manageable swarf and reduces heat concentration at the cutting edge. These properties result in improved surface finish and fewer secondary operations. For operations that demand steady throughput under variable conditions, this insert delivers efficiency gains and contributes to predictable production output.

FAQ

What materials is this insert suitable for?
The CNMG120404 T9235 indexable insert is designed primarily for steel machining; the T9235 grade provides toughness and wear resistance suited to interrupted cuts and less stable conditions.

Can this insert be used for internal turning as well as external turning?
Yes, the ISO CNMG 120404 form and rhombic geometry make the insert appropriate for both external and internal turning applications when used with the correct holder and mounting arrangement.

What are the distinguishing features of the T9235 grade?
The T9235 grade combines a tough carbide substrate with a CVD coating, offering a balance of fracture resistance and surface hardness that benefits performance in unstable cutting or interrupted operations.

How does the double-sided chipbreaker help in production?
The double-sided chipbreaker on this insert promotes predictable chip formation and evacuation, which reduces downtime from chip-related issues and helps maintain consistent surface finish during turning.

What should be checked for holder compatibility?
Holder compatibility depends on insert form, clearance angle, tolerance class, fastening method, overall size and thickness; ensure these match the ISO CNMG 120404 specification for reliable clamping and repeatable results.
