CNMG 120404 AH8005 Turning Insert for turning by Tungaloy

CNMG120404 AH8005 is an ISO-standard indexable turning insert optimised for stable machining of heat-resistant alloys and hard materials in external and internal turning operations

• ISO CNMG 120404 geometry
• PVD-coated carbide AH8005
• 0.4 mm corner radius
• Double-sided insert with hole

Increased tool life through wear-resistant coating

The combination of PVD-coated carbide and the AH8005 grade delivers a high resistance to flank wear and thermal degradation during demanding cuts. This results in longer intervals between index changes and fewer unplanned stops, which improves overall productivity. The coating technology stabilises the cutting edge under elevated temperatures typical of machining heat-resistant alloys, so the insert maintains geometry and contributes to consistent component tolerances.

Predictable surface finish and cutting stability

The ISO CNMG geometry with an 80° lead angle and a 0° relief angle provides a predictable cutting direction and a robust cutting edge, while the 0.4 mm corner radius supports fine finishing without sacrificing edge strength. As a double-sided indexable insert with a cylindrical hole, the part offers secure clamping and a defined datum for repeatable seating in the toolholder. These features reduce process variance and help achieve repeatable surface quality on serial production runs.

Fast integration into standard turning systems

Compatibility to a holder is determined by form, relief angle, tolerance class, attachment, size and thickness; this CNMG 120404 insert fits standard CNMG holders and requires no special adaptations. The insert’s 4.76 mm thickness and 12 mm size align with common toolholder specifications, enabling quick changeovers and straightforward inventory management. Selecting the appropriate chipbreaker and grade for the workpiece and machining stability ensures productive cutting and cost-effective operation.

Practical benefit: reliable machining of hard-to-machine materials

Designed for stable cutting conditions, the grade and geometry make the insert particularly suitable where consistent tool life and process security are needed. The stable cutting edge minimises rework and supports predictable cycle times, which is advantageous for batch manufacturing and precision components. The combination of technical robustness and easy handling reduces set-up time and supports continuous production.
