CNMG 120404 GT9530 ISO turning insert by Tungaloy — 0.4 mm corner radius, coated cermet

The CNMG120404 GT9530 is an ISO-standard indexable turning insert designed for finishing and light universal turning of steel, offering a coated cermet grade for improved surface quality and extended tool life.

• ISO CNMG geometry for wide holder compatibility
• Coated cermet GT9530 for extended life
• 0.4 mm corner radius for fine surface finish
• Double-sided chipbreaker for economical indexing

Consistent finish and extended edge life from a coated cermet grade

The GT9530 coated cermet is engineered for wear resistance and a fine machined surface when turning steel under stable conditions. Cermet combines ceramic and metallic properties to resist abrasive wear while maintaining edge strength; the applied coating improves adhesion and thermal stability, resulting in longer edge life and fewer changes. For finishing passes, the modest cutting geometry and the 0.4 mm corner radius help to reduce surface irregularities and vibration sensitivity, which in turn lowers rework rates and increases throughput.

Straightforward integration into ISO tool systems reduces setup time

The rhombic CNMG geometry with an included angle of 80° and a 0° clearance angle ensures predictable cutting directions and compatibility with standard holders. Important dimensions — 12 mm insert size, 4.76 mm thickness and a cylindrical clamping hole — define the mechanical interface and tolerance match to the toolholder. Compatibility is determined by form, free angle, tolerance class, fastening, size and thickness; matching these parameters avoids improper seating and delivers repeatable concentricity and clamping security for consistent cycles.

Economical indexing and process stability for productive turning

A double-sided chipbreaker allows both faces to be used, supporting indexed re‑use of cutting edges and improving cost-efficiency per edge. The chipbreaker geometry is suited to light finishing and universal turning; selecting the appropriate chipbreaker and grade according to material, machining type and machine stability optimises chip control and reduces built-up edge. Under steady conditions this combination supports higher machine uptime and a lower cost per component without compromising surface integrity.

Application guidance and selection support for reliable results

Intended primarily for turning of steel, the insert performs best in finishing to light roughing operations where machine and workpiece rigidity are assured. For mixed or unstable setups, a different chipbreaker or a more robust grade may be preferable. Assistance is available to determine the ideal holder, clamping arrangement and cutting data: holders must match the CNMG form and dimensions, and the correct screw or clamp type ensures safe fixation.

FAQ

Which materials are suitable for this insert?
The CNMG120404 GT9530 is a coated cermet grade optimised for turning steel, particularly where a fine surface finish and extended edge life are required under stable machining conditions.

How does the 0.4 mm corner radius affect the machined surface?
A 0.4 mm corner radius produces a finer surface finish and reduces the tendency for chatter on finishing passes; it is recommended for low-to-moderate feed rates where dimensional quality is a priority.

Is the insert indexable on both sides?
Yes — the double-sided chipbreaker allows economical indexing of the insert faces, enabling re‑use of cutting edges and reducing tool change frequency.

What must be matched to ensure holder compatibility?
Compatibility depends on matching the CNMG form, free angle, tolerance class, fastening method, insert size and thickness; the cylindrical hole and rhombic shape must fit the chosen holder and clamping set.
