CNMG 120404 AH8005 ISO turning insert – Tungaloy
A CNMG 120404 AH8005 ISO turning insert for external and internal turning, optimised for heat‑resistant alloys and hard materials
- PVD-coated wear-resistant grade AH8005
- ISO CNMG 120404 geometry for standard holders
- Double-sided chipbreaker for stable cuts
- R 0.4 mm corner radius with 80° lead angle
Proven wear resistance for tough materials
The PVD-coated AH8005 grade on a cemented carbide substrate is designed for prolonged life when machining demanding materials. The coating reduces flank wear at elevated temperatures and supports consistent cutting-edge performance, which translates into fewer interruptions and predictable tool-change intervals. This insert is therefore suitable where stable machining and reduced rework are priorities.
Reliable chip control and surface quality
Built with a double-sided chipbreaker, the geometry promotes controlled chip formation and evacuation during turning. Consistent chip control reduces the risk of built-up edge and improves surface finish, making the tool appropriate for finishing and semi-finishing passes. The combination of geometry and grade supports repeatable results even under challenging cutting conditions, enhancing process efficiency.
Standardised fit and clear mounting parameters
The ISO CNMG form ensures compatibility with a wide range of external holders and boring bars, provided the holder matches in form, relief angle, tolerance, fastening, size and thickness. The insert’s measurements — 12 mm inscribed size and 4.76 mm plate thickness — and the presence of a cylindrical hole support secure clamping and repeatable positioning. Reference to geometry and dimensions simplifies holder selection and reduces setup times.
Application guidance for demanding alloys
Optimised for turning of heat‑resistant alloys and other hard materials, the insert performs best in stable set‑ups with minimal vibration and consistent feed rates. A modest corner radius of 0.4 mm and an 80° lead angle balance edge strength and cutting forces, allowing reliable material removal and acceptable surface integrity. For best results, pair the insert with rigid tooling and adjust speeds to the material’s thermal and mechanical properties.

FAQ
Which materials are suitable for this insert?
The CNMG 120404 AH8005 insert from Tungaloy is suited for heat‑resistant alloys and other hard materials where a wear‑resistant PVD grade and stable cutting conditions are required.
How is compatibility with a toolholder determined?
Compatibility depends on the holder’s form, relief angle, tolerance class, fastening method, size and thickness; matching these parameters ensures the ISO CNMG geometry seats correctly and clamps securely.
Is the insert double-sided and reversible?
Yes, the insert features a double-sided chipbreaker design, allowing indexable use for extended life and economic tool utilisation.
What cutting geometry supports edge strength and surface finish?
The 80° lead angle combined with an R0.4 corner radius offers a compromise between edge robustness and surface quality, suitable for finishing and semi-finishing in stable setups.
