CPMT090304 GT9530 Tungaloy turning insert (coated cermet, 0.4 mm radius)

The CPMT090304 GT9530 is an ISO‑standard rhombic turning insert for finishing and light universal turning of steel, engineered for stable setups and reliable surface quality.

• ISO CPMT 090304 geometry
• Coated cermet grade GT9530
• 0.4 mm corner radius for fine finishing
• Single-sided chipbreaker with 11° relief angle

Consistent finishing through a wear-resistant grade

The GT9530 coated cermet blend delivers a balance of surface quality and extended tool life, making it suitable for finishing and light universal turning of steel. The microstructure of the grade resists abrasive wear while preserving edge geometry, which reduces rework and helps maintain part tolerances. In practice, this means fewer insert changes in stable machining conditions and more consistent batch-to-batch results, supporting predictable process planning and reduced downtime.

Efficiency and stability from ISO-standard geometry

Adopting an ISO 090304 CPMT format ensures predictable fitment and repeatable clamping when paired with compatible holders. The rhombic insert form and the included 80° angle create a robust cutting edge for external and internal turning operations. Because compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness, using an ISO‑standard insert simplifies tool inventory and reduces setup variation for production environments.

Precise edge definition for fine surface finishes

The 0.4 mm corner radius provides a compromise between edge strength and fine finishing capability; it supports lower cutting forces yet produces a good surface texture when feeds and speeds are optimised. Coupled with the single-sided chipbreaker, this geometry is aimed at stable cutting scenarios where control of chip formation contributes directly to repeatable surface finish and tool life, especially in finishing passes where dimensional accuracy is critical.

Practical mounting and dimensional details that matter

Key dimensions influence both mechanical stability and clamping: plate thickness 3.18 mm, the 11° relief (facing) angle and the insert’s included 80° geometry ensure correct seating and force transmission in the toolholder. The insert features a cylindrical hole with a one‑side countersink (40°–60°) to match standard clamping systems, enabling secure fixation and easy replacement without compromise to runout or concentricity.

Application guidance and process optimisation

This insert excels in external and internal turning where stable fixturing and consistent cutting conditions prevail. Select the GT9530 grade and the single‑side chipbreaker when the priority is surface quality and extended life rather than aggressive metal removal. For roughing operations or unstable setups, consider alternative grades or chipbreaker geometries designed for higher robustness and chip evacuation.

For whom this insert is intended

Production machinists, toolroom engineers and OEM workshops seeking predictable finishing performance in steel turning will find this insert beneficial. The combination of ISO compatibility, cermet wear characteristics and controlled chip formation supports workflows that demand both dimensional accuracy and long tool life, aiding efficiency in batch production and precision prototyping.

FAQ

What materials is this insert designed for?
The CPMT090304 GT9530 insert is optimised for steel turning; the GT9530 coated cermet grade provides wear resistance and a good surface finish in stable cutting conditions.

Which toolholders are compatible with this ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; use holders specified for ISO CPMT 090304 geometry to ensure correct seating for the Tungaloy insert (SKU TUN6998308).

How does the 0.4 mm corner radius affect machining?
A 0.4 mm corner radius balances edge strength and finishing capability, supporting finer surface texture and reduced cutting forces during finishing passes with the GT9530 grade.

Is the insert suitable for internal turning?
Yes, the rhombic CPMT format and controlled chip formation make it suitable for internal turning where stable access and coolant conditions are available.
