CNMG120404 T9225 Tungaloy turning insert – ISO 120404, 0.4 mm radius

A CNMG120404 T9225 indexable insert engineered for external and internal turning where toughness under varying engagement and interrupted cuts is required.

• CVD-coated carbide grade T9225
• Universal for medium to heavy Stahl cutting
• ISO CNMG 120404, rhombic 80° geometry
• 0.4 mm corner radius for consistent edge strength

Reliable performance where cutting conditions vary

The CVD-coated carbide T9225 grade combines wear resistance with increased toughness, making it well suited to medium to heavy Stahl turning where the cut can change or be lightly interrupted. The CVD layer reduces flank and crater wear while the substrate preserves edge stability; together these factors deliver longer tool life and fewer insert changes, improving machine uptime. The result is a robust cutting solution that balances productive material removal rates with dependable dimensional consistency for batch and single-piece production alike.

Precise fit and system compatibility for predictable results

As an ISO-form indexable insert, the geometry and mounting are decisive for holder compatibility: form, relief angle, tolerance class, clamping method, size and thickness determine fit and clamping stability. This insert features a rhombic 80° geometry, a 0° relief angle, 4.76 mm thickness and a cylindrical hole for positive location. The double-sided chipbreaker design enables economical use of both cutting edges and contributes to consistent chip control. Specifying holders and shims that match these parameters ensures vibration resistance and repeatable contours in turned parts.

Practical handling and application guidance for efficient machining

Use this indexable turning insert with matched external holders, boring bars or tool posts together with the correct shim and screw set to complete the system. The 0.4 mm corner radius supports light chamfering and strength at the cutting edge while the double-sided chipbreaker suits a range of feed rates and depths of cut. Select the chipbreaker and grade according to workpiece rigidity and the required surface finish; the insert’s universal character simplifies inventory and enables quick changeovers, thereby supporting leaner tool management and predictable cycle times.

FAQ

What materials is this insert best suited for?
The insert is optimised for medium to heavy Stahl machining; the T9225 grade is designed for robust performance under variable engagement and light interruptions.

How does the CVD coating improve performance?
A CVD-coated carbide substrate reduces adhesive and abrasive wear on the cutting edge, extending service life and maintaining cutting geometry under demanding turning conditions.

Is the insert compatible with standard CNMG holders?
Compatibility depends on holder form, relief angle, tolerance class, clamping and thickness; the ISO CNMG 120404 format and cylindrical hole are standard for corresponding CNMG holders.

Can both sides of the insert be used?
Yes, the double-sided chipbreaker design allows use of both cutting edges, improving cost-efficiency per insert.
