CNMG090412 T9215 ISO turning insert for Drehen — Tungaloy

CNMG090412 T9215 is an ISO‑standard indexable turning insert designed for general external and internal turning operations in industrial machining.

• ISO rhombic insert, 80° cutting geometry
• CVD-coated carbide T9215 grade
• Double-sided chipbreaker design
• Rhombic form with cylindrical central hole

Optimised grade for productive medium‑steel turning

The T9215 grade is a CVD-coated carbide developed to combine good wear resistance with fracture toughness, making it suitable as a first choice for medium steel machining. Its microstructure and coating promote a consistent cutting edge, which translates into longer tool life and fewer interruptions for insert changes. For manufacturing environments that prioritise stable cycle times and repeatable component quality, this grade supports sustained productivity even under continuous or slightly interrupted cuts.

Geometry and system compatibility that reduce setup time

The rhombic CNMG090412 profile with an 80° cutting angle and 0° clearance is manufactured to ISO tolerances, so compatibility with standard CNMG toolholders is straightforward. The central cylindrical hole and precise thickness simplify clamping and positioning in the holder, reducing setup variation. This standardisation helps minimise rework and contributes to consistent surface finishes, benefiting shops that require rapid changeovers and predictable process behaviour.

Controlled chip formation and edge security for operational reliability

Featuring a double-sided chipbreaker and a 1.2 mm corner radius, the insert delivers reliable chip control and a robust cutting edge for interrupted or stable cuts. The chipformer geometry assists evacuation at typical turning feeds for steel, lowering the risk of built‑up edge and improving surface consistency. The combination of edge radius and chip control supports dimensional reliability, which is particularly valuable in batch production and precision turning applications.

Practical system considerations and material range

This insert is part of an ISO turning insert system that includes an appropriate external holder, backing pad or clamp set and replacement screws. The CVD-coated carbide composition is aimed primarily at medium steels but performs well under varied shop conditions when matched with the correct cutting data and holder stability. Selection of the chipbreaker and grade according to material, machining parameters and machine rigidity delivers the expected balance of productivity and tool life without complex parameter trials.

FAQ

What materials is this insert suitable for?
The CNMG090412 in T9215 grade is optimised for medium steel machining and provides a compromise of wear resistance and toughness for productive turning operations.

How does the chipbreaker design support production?
The double-sided chipbreaker on the insert assists consistent chip formation and evacuation, helping to maintain surface quality and reduce interruptions in continuous turning processes.

Is the insert compatible with standard toolholders?
Yes. The CNMG090412 geometry is manufactured to ISO dimensions and features a cylindrical central hole for secure clamping in standard CNMG toolholders.

What does the T9215 coating offer compared with uncoated grades?
The CVD coating of T9215 increases wear resistance while preserving edge strength, resulting in longer usable life and improved performance in medium-steel applications.
