CNMG 120408 T9225 indexable turning insert by Tungaloy — CVD‑coated cemented carbide for turning

A CNMG120408 T9225 indexable insert engineered for external and internal turning in steel, offering high toughness for interrupted cuts and variable engagement conditions.

• CVD-coated cemented carbide substrate
• T9225 grade for medium to heavy steel turning
• 0.8 mm corner radius for versatile finishes
• Double-sided, ISO CNMG 80° rhombic format

Consistent performance for medium-to-heavy steel turning

The insert is manufactured from cemented carbide with a CVD coating, providing a balance of wear resistance and toughness that suits demanding turning tasks. The T9225 grade is optimised for mid to heavy cuts and for operations where intermittent engagement or variable cutting forces occur; this means fewer unscheduled tool changes and a steadier production rhythm. The coating reduces flank wear and preserves cutting geometry over longer cycles, which translates into predictable part tolerances and improved process reliability.

Stable cutting and improved edge life under varying conditions

Thanks to the combination of substrate and coating, the geometry resists chipping during interrupted cuts and maintains a stable cutting edge at moderate to elevated cutting speeds. The 0.8 mm radius offers a compromise between strength and surface finish, allowing controlled chip formation and reduced burrs on turned components. For shops seeking efficiency, this results in lower tooling consumption and more consistent surface quality, supported by the insert’s robust nose radius and edge preparation.

Easy integration into ISO tool systems and practical handling benefits

As an ISO CNMG 120408 format with a cylindrical hole and double-sided design, the insert fits a wide range of standard holders and turning bars; compatibility is determined by form, clearance angle, tolerance class, attachment and size. The standardised 80° rhombic shape and 4.76 mm plate thickness enable quick indexing and economical use of each insert. Using standard clamping and replacement screws reduces set‑up time and simplifies inventory management, supporting lean workflows in small and large production environments.

FAQ

What materials is this insert designed to machine?
The CNMG120408 T9225 insert is designed primarily for steel machining and is specified for medium to heavy steel turning where toughness is required.

Is this insert suitable for interrupted cuts?
Yes, the T9225 grade and the CVD-coated cemented carbide substrate are selected to offer enhanced resistance to chipping during interrupted or variable engagement conditions.

How does the ISO CNMG format aid toolroom logistics?
The ISO CNMG120408 form is a widely accepted standard, enabling interchangeability between holders and simpler inventory control; the double-sided design also maximises usable edge count.

What edge preparations or finishes can be expected with a 0.8 mm radius?
A 0.8 mm corner radius delivers a balance between edge strength and surface finish, producing controlled chip formation and reliable surface quality in typical turning operations.

Which holders and clamping arrangements are compatible?
Compatibility depends on holder form, clearance angle, tolerance class, attachment and size; the insert’s cylindrical hole and ISO geometry suit many standard external holders and turning bars.
