CNMG 120408 T9235 CNMG Turning Insert by Tungaloy — CVD-coated carbide, 0.8 mm nose radius

The CNMG 120408 T9235 is an ISO-standard rhombic indexable insert for external and internal turning, designed for stable chip formation and robust performance under interrupted cuts.

• CVD-coated carbide for toughness
• 0.8 mm nose radius for versatile profiles
• 0° clearance for stable cutting

Consistent cutting in unstable conditions

The CVD-coated carbide grade T9235 provides a tough, wear-resistant cutting edge tailored for machining steel at reduced cutting speeds and in less stable setups. The coating improves surface hardness and extends edge life while the substrate maintains fracture resistance, so the insert resists notch formation during interrupted cuts. Built for indexable turning, the component’s geometry supports a controlled chip flow: the double-sided chipbreaker reduces clogging and promotes predictable chip breakage, which aids cycle-time consistency and reduces secondary handling.

Practical fitment and secure clamping for efficient tool changes

Compatibility with the clamping system is determined by form, clearance, tolerance class, fastening, size and thickness; this ISO-conform insert features a rhombic shape with an 80° included angle and a cylindrical bore, ensuring secure locating and reliable repeatability in suitable holders or boring bars. The insert’s 0° free angle and the 0.8 mm nose radius make it versatile for general-purpose turning and profile work, while the two usable cutting edges per face improve economy by enabling re-indexing. Clear indication of hole style and plate thickness supports quick verification at tool change, minimising downtime in production environments.

Optimise tool life and process stability

Choose machining parameters that reflect the grade’s emphasis on toughness: moderate cutting speeds and conservative feeds will extend edge life when facing interrupted or unstable cuts. The CVD coating provides thermal resistance and reduces abrasive wear, while the insert’s geometry supports a repeatable contact pattern that helps maintain surface finish. For those prioritising productivity, the insert’s ability to perform reliably in variable conditions translates into fewer tool changes and steadier part quality, contributing to predictable throughput and lower overall tooling cost per component.

FAQ

What materials is this insert best suited for?
The Tungaloy CNMG 120408 T9235 insert is formulated for steel machining, offering toughness and wear resistance for interrupted cuts and less stable conditions.

How many cutting edges are usable on the insert?
The rhombic, double-sided design provides multiple usable edges; the insert can be re-indexed to exploit additional cutting corners, improving economy per plate.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, clearance, tolerance class, fastening, size and thickness; the ISO-standard geometry of the CNMG120408 simplifies selection for standard CNMG external and internal turning holders.

Does the insert require a special chip control strategy?
The built-in double-sided chipbreaker promotes controlled chip formation; for best results, select feeds and speeds aligned with the grade’s emphasis on toughness—moderate speeds and appropriate feed rates enhance chip splitting and surface finish.

What advantages does the T9235 coating bring compared with uncoated grades?
The T9235 CVD coating increases wear resistance and thermal stability while the carbide substrate maintains fracture toughness, yielding longer life in interrupted cuts and under unstable machining conditions.
