CPMT090304 GT9530 Tungaloy insert — ISO rhombic turning insert, 0.4 mm radius

The CPMT090304 GT9530 is an ISO rhombic turning insert designed for finishing and light universal turning of steel under stable machining conditions.

• Wear‑resistant GT9530 cermet grade
• ISO CPMT090304 rhombic form
• 0.4 mm corner radius for fine finish
• Cylindrical hole with 40°–60° countersink

Precision geometry for consistent surface quality

The rhombic, ISO‑conforming geometry of this indexable cutting insert ensures a controlled cutting edge and reliable engagement during external and internal turning. With an included angle of 80° and an 11° relief angle, the geometry is optimised to deliver a fine surface finish while reducing cutting forces in stable setups. The 0.4 mm corner radius supports low‑deflection cutting on medium feeds, which helps maintain dimensional accuracy and repeatability on serial parts.

Coated cermet grade that extends tool life

Equipped with the GT9530 coated cermet grade, the insert combines wear resistance with thermal stability for improved life in finishing operations on steel. The coating and substrate pairing promote stable chip formation and good surface integrity, meaning fewer indexings and reduced downtime. For operations where consistent part appearance and longer tool life are priorities, this grade offers a favourable cost‑to‑performance ratio under steady cutting conditions.

Compatibility and system considerations explained

Compatibility with toolholders is determined by the insert’s shape, relief angle, tolerance class, fastening method, size and thickness. The CPMT090304 form requires a matching rhombic holder and the standard clamping set (support pad and clamp) with appropriate screws. The insert has a cylindrical central hole with a single‑sided countersink (40°–60°) for secure fastening and accurate positioning, and a thickness of 3.18 mm, ensuring stable locating in most ISO holders.

Application guidance and practical benefits

This indexable insert is intended primarily for turning applications where a high‑quality finish and extended tool life are needed under stable machining conditions. It is best used as a finishing to light universal grade on steel, with the single‑sided chipbreaker assisting in controlled chip flow for standard depth‑of‑cut scenarios. Selecting the correct chipbreaker and insert grade for the workpiece material and rigidity of the setup will directly influence productivity and part quality.

Simple system setup and maintenance advantages

The system approach comprises the ISO insert, a compatible external holder or boring bar, a support pad/clamp set and replacement screws. Because insert interchange and indexing are fast, workshop throughput improves and non‑productive time is reduced. The standardised ISO format also simplifies tool inventory management and makes it easier to match inserts across different machines and toolholders.

FAQ

What materials is this insert best suited for?
The CPMT090304 GT9530 insert is optimised for turning steel, offering finishing to light universal performance when stable machining conditions are maintained.

How does the GT9530 grade improve performance?
The GT9530 coated cermet combination provides enhanced wear resistance and stable chip formation, extending tool life in finishing applications with consistent results.

Which holder features are required for correct mounting?
A matching rhombic ISO holder with appropriate clamping geometry and a support pad/clamp set is required; the insert’s cylindrical hole with 40°–60° countersink secures correct positioning.

Can this insert be used for roughing operations?
The insert is designed primarily for finishing to light universal turning; for heavy roughing, a different geometry and grade engineered for high‑feed or heavy‑cut conditions is recommended.

What is the corner radius and how does it affect surface finish?
The insert has a 0.4 mm corner radius, which supports a finer surface finish and reduced edge stress at moderate feeds, improving part appearance and dimensional stability.
