CNMG 120404 T9225 turning insert by Tungaloy — ISO rhombic insert, 80° cutting angle

The CNMG120404 T9225 is an ISO rhombic turning insert designed for external and internal turning operations, providing a balance of toughness and wear resistance for medium to heavy steel machining.

• CVD-coated carbide for enhanced wear resistance
• Robust universal grade T9225 for steel machining
• Rhombic CNMG insert with 80° cutting angle
• 0.4 mm corner radius, double-sided chipbreaker

Predictable tool life through proven coating and grade

The CVD-coated cemented carbide grade T9225 combines a wear-resistant surface layer with a tough substrate to extend edge life under varying engagement conditions. This coating reduces flank wear and stabilises performance during longer cycles, which translates into fewer tool changes and higher uptime. The description of the ISO-format insert emphasises compatibility with standard holders and ensures consistent seat and clamp engagement when the correct holder geometry is selected.

Geometry designed for versatile turning applications

The rhombic CNMG form (80° cutting angle) and a 0.4 mm corner radius yield a versatile cutting geometry suitable for contouring and general turning in steels. The 80° approach provides increased neck clearance for stable roughing and finishing passes, while the modest radius supports edge strength without compromising surface finish. The double-sided chipbreaker allows both sides of the insert to be used, improving economics by offering multiple indexable edges before replacement.

Practical integration with standard tool systems

An ISO turning system using this insert typically comprises an ISO CNMG insert, a matching external holder or boring bar, an appropriate shim or clamping set and spare screws. Compatibility depends on the holder form, clearance angle, tolerance class, fastening method, size and thickness, so selecting a holder that matches these parameters ensures correct seating and repeatable cutting conditions. The CNMG120404 geometry with a cylindrical hole is suitable for common clamping systems used in lathes and turning centres.

Process security and application advice for steel machining

Grade T9225 is intended as a robust universal solution for medium to heavy steel machining where occasional interruptions or variable engagement demand increased toughness. The double-sided chipbreaker supports consistent chip formation and evacuation in heavier cuts, reducing the risk of workpiece damage or spindle load spikes. For optimised results, pair the insert with holders that provide stable support and fine-tune cutting data according to material class and machine rigidity to achieve predictable cycle times.

FAQ

Which materials is this insert best suited for? The CNMG120404 T9225 insert is formulated for medium to heavy steel machining; the CVD-coated cemented carbide grade provides wear resistance and toughness for such applications.

Can this insert be used in standard CNMG holders? Yes. The CNMG120404 geometry is ISO-standard; compatibility requires a holder that matches form, clearance angle, tolerance class, fastening method, size and thickness for secure seating.

Is the insert indexable and reversible? The insert features a double-sided chipbreaker, so both faces are usable for multiple indexings, improving cost-per-edge compared with single-sided designs.

What does the T9225 grade offer in practice? T9225 is a robust universal grade offering increased toughness for interrupted cuts and variable engagement, balancing wear resistance with edge stability in steel turning.

How does the chipbreaker affect machining? The double-sided chipbreaker on this CNMG insert enhances chip control during medium to heavy cuts, promoting consistent evacuation and reducing the risk of tool or workpiece damage.
