CNMG120404 GT9530 CNMG turning insert by Tungaloy — coated cermet, 0.4 mm nose radius

CNMG120404 GT9530 is a precision ISO‑standard turning insert for finishing and light universal turning on steel components

• ISO‑standard rhombic CNMG profile
• Coated cermet grade GT9530
• 0.4 mm nose radius for fine finish
• Double‑sided chipbreaker, cylindrical hole

Consistent fine surface and controlled wear for finishing work

The coated cermet GT9530 is formulated to deliver improved wear resistance and a superior surface finish when turning steel under stable conditions. The combination of a finely engineered cutting edge and a 0.4 mm nose radius reduces built‑up edge and produces repeatable finishes, making the insert particularly suitable for semi‑finishing to finishing cuts. Where longer life per edge is required, the coating stabilises abrasive wear and helps maintain dimensional accuracy across serial runs.

Secure mounting and ISO compatibility for predictable production

As an ISO‑standard rhombic insert, the CNMG geometry and the cylindrical hole ensure compatibility with a wide range of carriers and boring bars when matched by form, clearance angle, tolerance class, fastening method, size and thickness. The 80° included angle contributes to robust support in the pocket and helps reduce chatter in rigid setups. Correct clamping and a stable toolholder arrangement translate directly into longer tool life and fewer interruptions during turning cycles.

Efficient chip control and economical edge usage

The double‑sided chipbreaker design offers two usable cutting edges per insert, improving cost efficiency for batch production. The GT9530 chipformer is tuned for chip control on steel grades commonly encountered in turning operations, helping to evacuate chips cleanly and reduce rework. In practical terms, this means less downtime for tool changes and steadier cycle times, particularly when paired with stable workholding and appropriate cutting parameters.

Recommended applications and handling notes

Optimised for external and internal turning tasks on steel, the insert performs best under stable cutting conditions and moderate feeds appropriate to a finishing or light universal grade. The plate thickness of 4.76 mm and the size designation of 12 provide sufficient rigidity for fine finishing, while the 0° free angle requires matching holder geometry to achieve the intended cutting clearance. For maximised performance, select holder geometry and cutting data that complement the insert’s profile and the workpiece material.

FAQ

What materials is this insert suitable for?
The GT9530 coated cermet grade is designed primarily for turning steel, offering wear resistance and surface quality for finishing and light universal operations.

What nose radius does the insert have and how does it affect the finish?
The insert features a 0.4 mm nose radius, giving a balance between edge strength and the ability to achieve a fine surface finish on turned components.

Is the insert reversible and how many edges are available per insert?
Yes — the double‑sided chipbreaker provides two usable cutting edges per insert, delivering economical edge usage for serial production.

How is compatibility with toolholders determined?
Compatibility depends on the insert form, included angle, relief (free) angle, tolerance class, fastening style, size and thickness; matching these parameters ensures proper clamping and stability for the CNMG120404 insert.

What are the manufacturer and part references for ordering?
Ordering can be referenced by the article number 6735854, SKU 6735854-Tungaloy or manufacturer SKU TUN6735854 for the CNMG120404 GT9530 Tungaloy insert.
