CNMG 120408 GT9530 ISO turning insert for finishing and light universal turning — Tungaloy

The CNMG 120408 GT9530 is an ISO rhombic turning insert designed for external and internal turning, delivering improved surface finish and extended tool life in stable setups.

• Coated cermet grade GT9530
• Double-sided chipbreaker
• 0.8 mm corner radius r0.8
• ISO CNMG 120408, 80° rhombic form

Efficient finishing and longer tool life for steel turning

The coated cermet GT9530 combines wear resistance with an ability to produce a finer surface than many standard carbides; as a result, finishing passes and light universal turning in steel benefit from a consistent surface finish and reduced rework. The coating enhances thermal and abrasive resistance which, under stable clamping and machining conditions, translates into longer tool life and fewer insert changes. This contributes directly to improved process efficiency and lower total operating time per component.

Clear guidance on compatibility and system integration

Compatibility with a tooling system is determined by the insert's geometric and fastening parameters: ISO CNMG 120408 form, 0° relief, tolerance class, fastening type, size and thickness must match the chosen holder. The rhombic, 80° shape and the cylindrical hole require a suitable top-mount or screw-clamp external holder and the correct shim or clamp set. For predictable results, assemble the insert with the matched holder, underlay and replacement screws to ensure repeatable clamping and cutting conditions.

Grade selection and practical application advice

GT9530 is specified as a coated cermet for wear-resistant finishing to light universal turning of steel where good surface quality and extended life are priorities. The double-sided chipbreaker supports stable chip control when feeds and depths are moderate; the 0.8 mm corner radius provides a compromise between edge strength and edge definition. In practice, choose this grade for stable setups and finishing operations where minimised vibration and consistent chip formation are achievable.

FAQ

What materials is this insert suitable for?

The CNMG 120408 GT9530 is optimised for steel finishing and light universal turning; the coated cermet composition provides wear resistance and improved surface quality when conditions are stable.

How many cutting edges are available on the insert?

The double-sided design of the CNMG 120408 GT9530 offers multiple usable cutting edges; the exact number of indexes depends on the intended orientation and clamping practice for the rhombic ISO insert.

Which holders are compatible with this ISO insert?

Compatibility is defined by the insert form, relief angle, tolerance, fastening, size and thickness; holders specified for CNMG 120408 inserts with a cylindrical hole and a rhombic 80° seat are appropriate.

Is GT9530 suitable for roughing operations?

GT9530 is a wear-resistant cermet finishing to light universal grade intended primarily for finishing; for heavy roughing, a tougher carbide grade is generally preferred.

How does the corner radius affect performance?

The r0.8 corner radius balances edge strength and surface definition, improving edge life on finish passes while maintaining a good surface finish on steel components.
