CNMG 090402 GT9530 indexable insert for turning — Tungaloy

A CNMG090402 GT9530 indexable insert engineered for precision external and internal turning, optimised for fine surface finish and prolonged tool life in stable machining conditions

• GT9530 coated cermet for wear resistance
• 0.2 mm corner radius for fine surface finishes
• Double-sided chipbreaker for economical indexing
• ISO CNMG shape; 4.76 mm plate thickness

Consistent surface quality from a wear-resistant grade

The GT9530 is a coated cermet developed for wear-resistant finishing and light-general-purpose turning where surface quality and extended life are priorities. Cermet combines a ceramic matrix with metallic binders, which increases hardness and reduces flank wear compared with conventional inserts; this results in more consistent dimensional accuracy and a finer finish on common workpiece materials. In practice, the grade performs best under stable cutting conditions, where reduced built-up edge and predictable flank wear allow longer intervals between indexings and fewer interruptions to production.

Precise geometry and quick integration into ISO tooling systems

Designed to the ISO CNMG standard, the insert matches common external holders when form, relief angle, tolerance class, fastening, size and thickness are compatible. Key geometry features include a 0° relief angle, a 0.2 mm corner radius and a 4.76 mm thickness, which together deliver predictable cutting forces and controlled chip flow. The presence of a cylindrical hole enables secure fastening and repeatable clamping, while the rhombic shape offers access for both through-tool and conventional turning setups. Where higher stability is available, the double-sided chipbreaker allows economical re-indexing and reduces tooling cost per part.

Application guidance for efficient and reliable turning

This insert is intended principally for turning tasks that demand fine finishing and reliable life—external and internal profiles, light semi-finishing and finishing passes. When machining harsher or more abrasive alloys, pairing the grade with an appropriate chipbreaker and optimising feed and speed will preserve the cutting edge. The carbide substrate beneath the coating provides impact resistance during interrupted cuts, while the coating reduces adhesive wear during continuous operations. For cycle planning, the double-sided design halves the effective tooling cost by offering two usable edges per insert and simplifies inventory management in production environments.

FAQ

What materials is this insert best suited for?
The GT9530 grade is optimised for turning of common steels and provides improved surface finish and wear resistance when used under stable cutting conditions; select the chipbreaker and parameters according to the specific workpiece material.

How does the double-sided chipbreaker affect cost-efficiency?
A double-sided chipbreaker offers two usable edges per insert, which reduces tooling cost per edge and simplifies inventory management while maintaining consistent cutting performance.

Is the CNMG090402 compatible with standard ISO holders?
Compatibility depends on matching form, relief angle, tolerance class, fastening, size and thickness; the insert conforms to ISO CNMG standards, facilitating integration with corresponding external holders.

Why is a 0° relief angle specified and what does it mean in practice?
A 0° relief angle provides a stable cutting geometry for finishing passes; it reduces clearance requirements and helps maintain consistent cutting forces for superior surface quality.

What is the purpose of the cylindrical hole in the insert?
The cylindrical hole allows robust and repeatable clamping with compatible screws and pads, improving positional accuracy and reducing the risk of movement during turning operations.
