CNMG 120404 GT9530 Turning insert — Tungaloy, coated cermet, 80° rhombic

The CNMG120404 GT9530 is an ISO-format indexable insert designed for finish to light turning of steel in stable machining conditions.

• Coated cermet GT9530 for longer tool life
• 80° rhombic shape for versatile turning
• 0.4 mm corner radius for fine surface finish
• Cylindrical hole with double-sided chipbreaker

Consistent surface finish and extended service life

The GT9530 grade is a coated cermet developed for wear resistance and stable finishing on steel. In finish turning applications the composition of the cutting material reduces flank wear and improves edge integrity, which in turn supports more consistent surface finish and fewer interruptions for insert changes. The combination of a 0.4 mm corner radius and a purpose-designed chip control geometry produces a finer machined surface and lowers the risk of built-up edge under suitable cutting parameters. For shops focused on predictable component quality, this grade offers a measurable improvement in process stability.

Reliable geometry and system compatibility for productive turning

The 80° rhombic form and 0° relief provide a robust cutting edge and versatile orientation for both external and internal turning. The insert thickness of 4.76 mm and the ISO CNMG120404 designation ensure dimensional compatibility with standard ISO holders, while the cylindrical hole supports secure clamping. Note that compatibility with a given holder depends on the insert shape, relief angle, tolerance class, fastening method, size and thickness; matching the insert to the correct external holder and clamp set prevents assembly errors and maximises toolholder rigidity. This system approach—insert, holder, shim/clamp set and replacement screws—helps to maintain repeatable set-ups and shorter changeover times.

Application guidance: selecting chipbreaker and process settings

This insert is intended for finish to light general-purpose turning of steel where surface quality and extended run times are priorities. The double-sided chipbreaker offers two usable edges before indexation, improving cost-effectiveness in stable conditions. For optimal results, select the chipbreaker style and cutting data according to workpiece rigidity and required finish; lighter depths of cut and higher spindle stability favour the finishing capability of the GT9530 grade. For materials with different machinability or for interrupted cuts, consider an alternative chipbreaker or grade matched to the specific task.

FAQ

Which materials is this insert best suited for?
The CNMG120404 GT9530 insert is optimised for machining steel in finish to light general-purpose turning; the GT9530 coated cermet provides improved surface finish and extended life under stable cutting conditions.

How many edges are available before indexation?
The insert features a double-sided chipbreaker, providing two usable cutting edges per side; indexation doubles the available edges and supports economical tool consumption for the CNMG120404 GT9530.

What determines holder compatibility for this insert?
Compatibility depends on insert shape, relief angle, tolerance class, fastening method, size and thickness; the CNMG120404 format and 4.76 mm thickness suit standard ISO CNMG holders when the holder specification matches these dimensions.

Can the GT9530 grade be used for roughing?
GT9530 is a wear-resistant finishing to light universal grade; for heavy roughing, a more robust grade or different chipbreaker should be selected to handle higher loads and interrupted cuts.
