DCMT 070204 GT9530 indexable turning insert for finishing — Tungaloy

The DCMT070204 GT9530 is an ISO-standard rhombic indexable insert designed for turning operations, optimised for finishing to light general-purpose machining of steel under stable conditions.

• Coated cermet grade GT9530
• Rhombic ISO insert, size 07
• 0.4 mm corner radius for fine finish
• Single-side chipbreaker, with hole

Predictable surface quality and longer tool life

The combination of a coated cermet substrate and the GT9530 grade delivers a balance between wear resistance and surface finishing. Cermet is a ceramic–metal composite that offers enhanced thermal stability and reduced built-up edge compared with many carbides; this results in more consistent surface finish and prolonged intervals between index changes when used in stable turning setups. The modest 0.4 mm corner radius supports fine edge definition for light finishing passes, reducing the need for secondary operations.

Efficiency gains for steel turning in stable conditions

This insert is specified for turning with a focus on finishing or light universal cutting of steel. The single-side chipbreaker controls chip flow in predictable cutting regimes, helping to maintain process stability and reduce downtime. In practice, choosing this grade and geometry can lower cycle variability and improve part-to-part consistency, which benefits batch production and precision components where repeatable surface quality and tool life are critical.

Clear guidance on holder compatibility and mounting

Compatibility with toolholders depends on form, relief angle, tolerance class, fastening, size and thickness. The insert features a rhombic shape with a central hole and a cylindrical hole plus a one-sided countersink (40°–60°), so select holders rated for ISO rhombic inserts of size 07 and a plate thickness of 2.38 mm. The 7° relief angle and the ISO geometry ensure straightforward clamping and repeatable seating, simplifying tool changeover and minimising setup errors.

Practical selection and operating window

When opting for this grade, specify stable cutting parameters that favour finishing rather than heavy interrupted cuts. The coated cermet composition is best applied where a good surface and extended life are desired under steady feeds and speeds; aggressive interrupted cuts or heavy roughing may require a tougher carbide grade. The insert’s ISO designation and the documented geometry make it straightforward to match with appropriate Tungaloy holders and clamping sets, enabling efficient integration into existing turning systems.

FAQ

Is this insert suitable for finishing stainless or alloy steels?
The DCMT070204 GT9530 insert is optimised for steel finishing; for specific stainless or alloy applications, match the GT9530 wear characteristics to the material and cutting conditions to ensure optimal performance.

What clamping elements are required for correct seating?
Use an ISO-compatible holder for rhombic inserts of size 07 with clamping hardware that fits a 2.38 mm plate thickness and the central hole/countersink geometry; proper seating ensures the insert’s repeatability.

How does the GT9530 coating affect tool life?
The GT9530 coated cermet improves wear resistance and surface quality under stable cutting parameters, extending effective life in finishing operations compared with uncoated grades.

Can this insert be used for light roughing as well as finishing?
The insert is designed primarily for finishing to light general-purpose turning; light roughing may be possible but heavier interrupted or high-feed roughing is not recommended for best life.

What is the corner radius and why does it matter?
The insert has a 0.4 mm corner radius; this small radius supports finer surface finishes and reduces cutting forces in finishing passes.
