CNMG090404 T9215 ISO turning insert (rhombic, 80°) by Tungaloy

The CNMG090404 T9215 is an ISO-standard rhombic turning insert designed for external and internal turning operations in medium steel machining

• CVD-coated cemented carbide T9215
• Optimised for medium steel machining
• Double-sided insert with cylindrical hole
• 80° included angle, rhombic 09 form

Productive performance for medium steel turning

The CNMG090404 T9215 insert combines a CVD-coated surface with a cemented carbide substrate to deliver high wear resistance while maintaining fracture toughness. This balance allows for stable, productive machining in continuous to lightly interrupted cuts, where repeatable tool life and consistent surface finish are required. The grade is engineered to sustain higher cutting parameters, which reduces cycle times and contributes to improved process economics in series production.

Clear compatibility and clamping considerations

As an ISO-standard turning grade in rhombic 09 form with an 80° included angle, the geometry and tolerance class determine compatibility with external holders and boring bars. The insert features a cylindrical hole for positive locating and a 0° relief angle, so correct seat form and clamping torque are essential for repeatable results. Selection of a holder that matches the insert form, thickness and fastening method is required to ensure reliable chip control and to avoid edge instability.

Practical cutting behaviour and application guidance

The built-in double-sided chipbreaker is suited to medium steel applications where stable chip formation and evacuation support productivity. For predominantly steel workpieces, the cutting edge geometry and the T9215 coating combination favour sustained material removal rates with good surface integrity. Use the insert for external turning, light profiling and internal turning where the machining is continuous or only slightly interrupted; adjust feeds and speeds to balance tool life and productivity.

Predictable service life and process reliability

The inserted configuration promotes process reliability, providing predictable wear patterns and easier tool management in production. The coating reduces flank wear and helps maintain dimensional accuracy over longer tool cycles, lowering the need for frequent index changes.

FAQ

What workpiece materials is this insert intended for?
The CNMG090404 T9215 insert (Tungaloy, SKU 6772153-Tungaloy) is optimised for medium steel machining, combining wear resistance and fracture toughness for productive results.

Can the insert be used for internal and external turning?
Yes. The ISO rhombic form and cylindrical hole make the insert suitable for both external and internal turning when the correct holder and clamping setup are used.

How does the T9215 grade affect cutting parameters?
The T9215 CVD-coated grade supports higher cutting parameters in medium-steel applications, enabling increased material removal rates while maintaining tool life.

Is the chip control suitable for interrupted cuts?
The double-sided chipbreaker provides effective chip control in continuous and lightly interrupted cuts; heavier interruptions may require alternative geometries or process adjustments.

Which holder features are essential for reliable performance?
A holder matching the rhombic 09 form, proper seat geometry, correct clamping torque and compatible tolerance class are essential to exploit the insert’s stability and chip control.
