CNMG 120408 AH6225 Tungaloy turning insert — PVD‑coated carbide, rhombic 80° geometry

CNMG120408 AH6225 Tungaloy turning insert designed for ISO‑standard external and internal turning, offering a stable cutting edge for medium machining tasks

• PVD‑coated carbide for stainless steel
• ISO CNMG 120408 rhombic geometry
• 0.8 mm nose radius for improved profile control
• Double‑sided chipbreaker with cylindrical hole

Consistent fit and predictable mounting reduce set‑up time

The ISO CNMG 120408 geometry ensures compatibility across the established holder ecosystem; fit is determined by plate form, 0° relief, tolerance class, fastening type, size and thickness. This predictable interface minimises set‑up time and simplifies tool management in serial production. Compatibility means fewer adapter checks and reduced risk of mis‑mounting, while the rhombic form supports both external and internal turning tasks with repeatable positioning and mechanical stability.

Sharper, more reliable cutting on stainless steel

The AH6225 grade is a PVD‑coated carbide designed as a universal solution for stainless steel, combining a sharp cutting edge with structural stability under varying conditions. The double‑sided chipbreaker supports consistent chip control during medium cutting, and the 0.8 mm nose radius balances edge strength with detailed profile generation. PVD coating improves wear resistance and reduces built‑up edge, so surface finish and tool life are maintained even when machining stainless alloys that are prone to work‑hardening.

System advantages for efficient workshop integration

A complete system approach — insert, matching external holder or boring bar, pad/clamp and replacement screws — delivers operational benefits: quick indexability of double‑sided inserts, secure clamping via the central cylindrical hole, and consistent cutting height thanks to the 4.76 mm plate thickness. The 80° included angle and rhombic plate shape support stable cutting forces and straightforward access to part geometry. Together, these elements reduce downtime, simplify spare‑part stocking and contribute to a more productive machining cycle.

FAQ

Is this insert suitable for machining stainless steels?
The CNMG120408 AH6225 Tungaloy turning insert is specifically produced for stainless steel and offers a PVD‑coated carbide grade that provides a sharp yet stable cutting edge for medium cutting conditions.

Which holders work with the CNMG120408 geometry?
Compatibility depends on holder form, relief angle, tolerance class, fastening method, plate size and thickness; holders designed for CNMG inserts will accept the CNMG120408 AH6225 with the correct clamp or screw system.

Can the insert be indexed to a second cutting edge?
Yes, the double‑sided design permits indexing to a fresh edge, allowing two usable cutting edges per orientation and improving overall tool economy for the CNMG120408 AH6225 insert.

What benefits does the AH6225 PVD coating provide?
The AH6225 PVD coating enhances wear resistance and reduces built‑up edge when machining stainless steel, helping to maintain surface finish and extend insert life under variable cutting conditions.

What are the key geometric data to consider when selecting this insert?
Relevant data are the rhombic ISO CNMG shape, 12 mm plate size, 4.76 mm thickness, 0.8 mm nose radius and the central cylindrical hole for clamp fixation, all of which influence holder choice and cutting stability.
