CNMG 120412 T9225 — CNMG turning insert for turning by Tungaloy

A CNMG120412 T9225 ISO turning insert engineered for external and internal turning, offering a robust universal grade for medium to heavy steel machining.

• CVD-coated carbide T9225
• Universal grade for medium to heavy steel
• 1.2 mm corner radius, 80° rhombic
• Double-sided chipbreaker, cylindrical hole

Reliable wear resistance and stable cutting performance

The CVD-coated carbide composition of this insert delivers improved edge stability and wear resistance compared with uncoated grades, which translates into more predictable tool life and fewer changeovers. As a robust universal grade, T9225 balances toughness and hardness to cope with varied cut interruptions and slightly changing engagement conditions; this results in a steady surface finish and reduced scrap rates. The 1.2 mm corner radius provides enhanced edge strength while the 80° rhombic form supports consistent cutting geometry, helping to maintain dimensional accuracy on shafts and bore faces.

Cost efficiency through smart design and ISO compatibility

The insert’s ISO format and standard dimensions ensure ISO compatibility with a wide range of toolholders, simplifying inventory management and holder selection. The double-sided, indexable design halves the effective cost per cutting edge and speeds up routine maintenance, while the 4.76 mm thickness and rhombic profile increase mechanical stiffness for heavy cuts. The double-sided chipbreaker promotes repeatable chip formation; by controlling chip shape it lowers the risk of workpiece surface damage and improves chip evacuation in both external and internal turning operations.

Practical selection guidance and application fit

For medium to heavy steel turning where occasional interrupted cuts occur, this insert is a practical choice: the CNMG120412 T9225 insert combines toughness for shock resistance with a CVD wear layer for abrasion control. The cylindrical hole and standard fixing pattern support straightforward clamping and repeatable positioning in ISO holders. When selecting a chipbreaker or alternative grade, consider material type, depth of cut and machine rigidity — matching the insert’s properties to the machining conditions maximises productivity and extends service intervals.

FAQ

What materials is this insert suited for?
The CNMG120412 T9225 insert is designed primarily for medium to heavy steel machining; the CVD-coated carbide grade provides a balance of wear resistance and toughness for these applications.

Can the insert be used in interrupted cuts?
Yes, the T9225 grade and the insert’s robust geometry are suitable for slightly interrupted and variable engagement conditions common in many turning operations.

How does the double-sided chipbreaker benefit production?
A double-sided chipbreaker offers repeatable chip control on both edges, improving chip evacuation and reducing the risk of surface damage during turning operations.

Is the insert compatible with standard ISO holders?
The insert follows ISO dimensions and mounting patterns; compatibility is determined by holder form, relief angle, tolerance class, fixing method, size and thickness.

How many usable cutting edges are available before replacement?
As a double-sided, indexable insert, it provides multiple cutting edges that can be rotated to present fresh edges; effective edge count depends on wear behaviour under the specific cutting parameters used.
