CPMT090304 GT9530 — ISO indexable turning insert by Tungaloy, rhombic 80° with 11° clearance

The CPMT090304 GT9530 is an ISO rhombic indexable insert for external and internal turning, designed for finishing and light universal machining of steel.

• ISO rhombic 80° geometry
• Coated cermet grade GT9530
• Single-sided chipbreaker
• Cylindrical hole with countersink 40°–60°

Consistent, high-quality finishes on steel

The coated cermet grade GT9530 is formulated for wear resistance and surface integrity during finishing and light universal operations on steel. Compared with uncoated grades, the substrate and coating combination reduces flank wear and supports longer intervals between index changes, which is particularly beneficial in stable, vibration-minimised setups. The resulting improvement in productivity is measurable as reduced rework and more consistent part tolerances, making this insert suitable where surface finish and repeatability matter.

Secure geometry and ISO compatibility for reliable clamping

The rhombic 80° form with an 11° clearance angle follows ISO conventions for turning inserts; compatibility with holders depends on form, clearance, tolerance class, fastening and thickness. The presence of a cylindrical hole with a single-sided countersink (40°–60°) ensures tactile, repeatable clamping and straightforward replacement of the indexable plate. Using correctly matched holders and torque settings minimises movement under cutting forces and preserves dimensional accuracy over longer production runs.

Efficient chip control and application focus

A single-sided chipbreaker on this plate promotes predictable chip flow during finishing cuts and light turning operations, reducing the risk of chip interference and tool nose damage. Cermet substrates tend to offer a smoother cutting edge and resist built-up edge formation, which explains the improved surface quality seen with this grade. Select this insert when process stability is achievable and when the priority is better surface finish and extended tool life rather than heavy roughing cuts.

Integrating the insert into production for reduced downtime

For the most efficient implementation, pair the plate with ISO-compatible external holders or boring bars and ensure the mounting stack (support, clamp set and replacement screws) matches the plate thickness of 3.18 mm and the hole style. Correct combination of holder stiffness and cutting parameters preserves the GT9530 advantages: consistent results, predictable wear and fewer tool exchanges. If process requirements change, consider alternative chipbreakers or grades matched to higher feed or interrupted cutting conditions.

FAQ

What materials is this insert best suited for?
The CPMT090304 GT9530 insert is optimised for machining steel, offering a wear-resistant coated cermet substrate that favours finishing and light universal turning operations.

How does the GT9530 grade improve surface finish?
The coated GT9530 cermet provides a stable cutting edge and reduced tendency for built-up edge, which helps to deliver improved surface quality compared with many uncoated grades.

Which holders are compatible with this ISO plate?
Compatibility is determined by the rhombic form, plate thickness (3.18 mm), clearance angle (11°), hole style and tolerance class; choose ISO-compatible external holders or boring bars that match these parameters.

What advantage does the cylindrical hole with countersink provide?
The cylindrical hole with a single-sided countersink (40°–60°) ensures secure, repeatable clamping and simplifies replacement, contributing to consistent tool positioning and machining accuracy.

Is this insert suitable for heavy roughing?
This plate is designed for finishing to light universal duties; for heavy roughing, a more robust grade or geometry optimised for high material removal should be chosen.
