CNMG120408 T9225 Tungaloy — ISO turning insert for external and internal turning, CVD‑coated carbide, 0.8 mm corner radius

CNMG120408 T9225 Tungaloy is an ISO‑standard rhombic turning insert designed for reliable performance in demanding steel turning applications

• ISO CNMG120408 rhombic insert, 80° geometry
• CVD‑coated carbide, robust universal grade T9225
• Double‑sided chipbreaker, cylindrical hole
• 0.8 mm corner radius, 4.76 mm thickness

Consistent productivity with a tough universal grade

The T9225 designation identifies a CVD‑coated carbide developed for a wide range of steel machining tasks where toughness and stable chip formation are required. Because the substrate and coating combination is balanced for moderate to heavy cutting, the insert sustains performance under changing engagement conditions and slight interruptions in the cut. This results in improved tool life and a lower cost per component when compared with grades optimised only for finishing. The CVD layer enhances wear resistance while the tough core absorbs intermittent shock, so cycle times and scrap rates are reduced in production environments.

Easy integration into ISO tooling systems for secure clamping

The CNMG geometry follows ISO standards, so compatibility with standard external holders and boring bars is determined by the insert form, 0° relief, tolerance class, fastening method, physical size and thickness. The presence of a cylindrical hole facilitates positive location and clamping in many common seat designs. The rhombic shape with an 80° included angle provides a compromise between strength and access, making the insert suitable for both face and profile turning. Where holder choice is critical, match seat form and tolerance class to the insert specification to ensure stable clamping and repeatable results.

Practical advantages and typical applications

A double‑sided chipbreaker allows use of both cutting edges before indexation, increasing effective cutting length and reducing tooling changes. The 0.8 mm corner radius offers a good balance between edge strength and surface finish, suitable for general turning and light shoulder work in steel. With a plate thickness of 4.76 mm the insert provides stiffness that supports higher feeds without excessive vibration. Typical applications include external and internal turning of steel components under varying engagement conditions; the selection of chipbreaker and grade should be aligned to workpiece material, cutting mode and machine stability to extract the best performance from this insert.

FAQ

What materials is this insert best suited for?
The CNMG120408 T9225 insert is designed primarily for steel machining; the T9225 CVD‑coated carbide grade delivers toughness and wear resistance for medium to heavy steel turning.

How does the 0.8 mm corner radius affect the machining result?
A 0.8 mm corner radius increases edge strength and reduces chipping risk while still supporting a decent surface finish, making the insert versatile for general turning operations.

Can the insert be used in both external and internal turning?
Yes, the ISO CNMG form and rhombic geometry are suitable for both external and internal turning when paired with the appropriate holder and seat type.

How many usable cutting edges are available before replacement?
The double‑sided design provides multiple indexable edges; rotation and indexing depend on the holder and machining cycle, but the layout increases effective cutting length and reduces downtime.

What should be checked to ensure holder compatibility?
Compatibility is determined by insert form, relief angle, tolerance class, fastening method, size and thickness; confirm the holder seat matches ISO CNMG specifications before assembly.
