CNMG 090402 GT9530 — Turning indexable insert (Tungaloy)

The CNMG090402 GT9530 is an ISO‑format indexable insert designed for external and internal turning, offering wear‑resistant finishing performance in stable machining conditions.

• Coated cermet grade GT9530 for extended life
• ISO‑standard CNMG insert for turning operations
• Radial nose radius 0.2 mm for fine finishing
• Rhombic 80° geometry with central cylindrical hole

Achieve consistent finishes with a wear‑resistant cermet grade

The coated cermet composition of the GT9530 grade is engineered for wear‑resistant finishing, delivering improved surface quality and longer service intervals when machining steel under stable conditions. Cermet is optimised for low built‑up edge and reduced adhesion, which translates into a more consistent part finish compared with uncoated ceramics. The insert’s small nose radius of 0.2 mm helps produce precise edge definition with minimal tool mark visibility, making it suited to light turning and finishing passes where dimensional accuracy and surface integrity are priorities.

Faster setup and predictable process security through ISO compatibility

Compatibility with toolholders is defined by ISO designation, relief angle, tolerance class, mounting method, size and thickness, so the CNMG form is widely supported across commercial turning holders. The standardised form of this insert simplifies inventory management and reduces setup time because holders and spare screw kits are interchangeable in many systems. In practice, this means process planners can rely on repeatable clamping behaviour and predictable runout characteristics, which supports higher throughput and lower scrap rates when combined with appropriate holder damping and stable cutting parameters.

Geometry and system design that support versatility and tool economy

The rhombic 80° geometry provides a balanced approach between accessibility and robustness, while the central cylindrical hole and double‑sided chipbreaker permit reversible indexing to maximise usable edges. With a 4.76 mm thickness and size 09 body, the insert is compatible with common external holders or boring bars and is used together with a shim/clamping set and replacement screws as part of a complete system. The doubled chipbreaker design improves chip control on both cutting directions, and the coated surface enhances resistance to flank wear, extending useful life under steady‑state cutting.

FAQ

Which materials is this insert best suited for?
The GT9530 grade is a wear‑resistant cermet developed for finishing and light universal use on steel; it provides good surface quality and extended life in stable conditions.

Can the insert be used for both external and internal turning?
Yes, the CNMG090402 geometry is designed for both external and internal turning when mounted in a compatible holder or boring bar.

Is the insert reversible and how does the chipbreaker behave?
The insert is double‑sided with a two‑sided chipbreaker, enabling reversible indexing to use multiple cutting edges and improving chip control in both orientations.

What are the key dimensions and identification codes to check before ordering?
Check designation CNMG090402, ISO code 090402, size 09, thickness 4.76 mm, nose radius 0.2 mm and manufacturer SKU TUN6797210 to ensure correct fit.

How is holder compatibility determined for this ISO insert?
Compatibility depends on the CNMG form, relief angle 0°, tolerance class, mounting type, size and thickness; these factors determine correct seating and clamping in a given holder.
