CNMG 120404 AH110 — Tungaloy CNMG120404 PVD-coated carbide turning insert, 80°

CNMG120404 AH110 is an ISO-format turning insert for general external and internal turning, designed to deliver stable cuts and secure clamping in CNMG-compatible holders

• PVD-coated carbide for high wear resistance
• ISO CNMG geometry with 80° cutting angle
• 0.4 mm nose radius for stable cutting
• Double-sided insert, cylindrical central hole

Stable cutting performance for consistent surface quality

The rhomboid CNMG geometry with an 80° cutting angle and a 0.4 mm nose radius gives predictable contact conditions at the cutting edge. This geometry helps to reduce vibration and supports consistent chip formation, which directly improves surface finish and dimensional repeatability during both light finishing passes and more demanding turning cycles. The double-sided design increases cost-effectiveness by providing two indexed cutting edges per side, helping to extend the service life per insert and lower the effective cost per cutting edge.

Process security through AH110 PVD-coated carbide

The AH110 grade is a PVD-coated carbide formulated for wear resistance and edge stability where a sharp cutting edge and reliable performance are required. The coating reduces flank wear and helps to maintain a sharp profile under intermittent or continuous cutting conditions, while the substrate hardness and fracture resistance reduce the risk of chipping. Together, these properties support longer tool life and fewer tool changes, increasing machine uptime and contributing to predictable production throughput.

Easy integration into ISO tool systems and organised toolrooms

Compatibility with standard holders is ensured by the ISO-format designation and the CNMG outline; correct fit depends on form, clearance angle (0°), tolerance class, fastening method, size and thickness. The insert features a cylindrical central hole for positive clamping and a plate thickness of 4.76 mm, simplifying retrofits into existing toolholders or boring bars. For shop-floor logistics, the ISO standardisation and Tungaloy manufacturing tolerances make stock management and reordering straightforward, while the system build—insert, holder, underlay/clamp and replacement screws—delivers a practical, serviceable tooling solution.

FAQ

What are the principal advantages of this insert compared with uncoated grades?
The PVD-coated CNMG 120404 AH110 offers improved wear resistance and a more durable cutting edge than uncoated carbide, which helps to extend tool life and maintain surface quality under continuous turning loads.

Is the insert suitable for both external and internal turning operations?
Yes, the CNMG format and the rhomboid outline allow use in both external turning and internal applications when paired with appropriate external holders or boring bars.

How should the insert be clamped in the toolholder?
The insert uses a cylindrical central hole and is intended for positive clamping in CNMG-compatible holders, together with the standard underlay/clamp and fastening screw.

What machining outcomes can be expected from the 0.4 mm radius?
A 0.4 mm nose radius balances good surface finish with edge strength, making it suitable for finishing and general turning passes where a controlled profile and consistent edge contact are required.
