CNMG 120404 GT9530 — ISO indexable turning insert by Tungaloy, coated cermet for finishing and light universal steel turning

CNMG 120404 GT9530 is an ISO-standard, rhombic indexable insert designed for external and internal turning where good surface quality and longer tool life under stable cutting conditions are required.

• Coated cermet GT9530 for wear resistance
• ISO CNMG 120404 format, 80° included angle
• 0.4 mm corner radius for fine surface finish
• Double-sided chipbreaker, cylindrical hole

Consistent finish and extended tool life

The CNMG120404 GT9530 is specified as a coated cermet grade that prioritises wear resistance and a refined surface finish in finishing operations. The fine 0.4 mm corner radius contributes to reduced cutting forces and minimal vibration when run under stable setups, which in turn prolongs tool life and reduces part rework. Cermet substrates combine ceramic hardness with metallic toughness; the coating further improves abrasion resistance while maintaining a sharp cutting edge for improved dimensional control.

Designed for secure fit and reliable turning

Produced to the ISO CNMG120404 form, the insert's rhombic form, 80° included angle and cylindrical hole ensure reliable seating and clamping in compatible holders. Compatibility with a given holder is determined by the insert form, clearance angle, tolerance class, clamping method, size and thickness — these parameters must match the toolholder specification to guarantee repeatable cutting geometry. The defined geometry provides a robust cutting edge for general turning while retaining versatility for internal and external operations.

Practical performance guidance for production use

The double-sided chipbreaker design offers two cutting faces per side that support consistent chip formation when matched to material and process stability. Select the chipbreaker and grade according to the workpiece material, machining type and rigidity of the setup: the GT9530 grade performs best on steels where a finishing to light universal approach is required. For reliable results, use stable clamping, controlled feeds and appropriate coolant or lubrication where applicable to exploit the insert's strengths in surface quality and stand time.
