CNMG 120404 AH6225 Turning insert (ISO 120404) for Turning – Tungaloy

CNMG 120404 AH6225 Tungaloy turning insert delivers a sharp yet stable cutting edge optimised for medium turning tasks, particularly on stainless steel.

• ISO CNMG shape, 80° cutting geometry
• PVD-coated carbide grade AH6225
• Double-sided chipbreaker for extended use
• Rhombic form with 0.4 mm corner radius

Consistent, dependable cutting performance that raises uptime

The PVD-coated grade AH6225 provides a sharp, stable cutting edge for a wide range of conditions encountered during turning. The combination of a wear-resistant PVD coating and a dense carbide substrate reduces flank wear, which translates into more predictable tool life and fewer unscheduled tool changes. For production environments seeking steady component quality, this insert supports repeatable surface finish and dimensional stability, helping to maintain throughput with less rework.

Lower total cost of operation through dual-sided use and ISO compatibility

Built as a double-sided insert in the ISO CNMG format, the CNMG120404 AH6225 Tungaloy insert offers two cutting edges per index, effectively doubling the available edges before needing replacement. The standardised ISO geometry ensures broad holder compatibility and simplifies stock management of spare parts. Fewer changeovers and standardised tooling reduce machine downtime and logistic complexity, delivering a measurable contribution to operational economy without compromising machining performance.

Easy integration into existing turning setups and appropriate selection guidance

Compatibility with a holder depends on shape, clearance angle, tolerance class, fixing method, size and thickness; the rhombic CNMG form, 80° approach angle and cylindrical clamping hole ensure secure seating and straightforward indexing. The 0° relief angle and 0.4 mm corner radius balance strength and finish — a smaller radius favours better surface quality, while the chosen radius maintains edge robustness. When pairing the insert with a holder, select a chipbreaker and grade tuned to the workpiece material and machine rigidity for optimal results.

FAQ

What workpieces is this insert best suited for?
The CNMG120404 AH6225 Tungaloy insert is designed primarily for turning stainless steel in medium cutting conditions; the AH6225 grade balances sharpness and stability for such materials.

How does the PVD coating benefit machining?
The PVD coating on the AH6225 grade reduces adhesive wear and improves thermal resistance, which helps the CNMG120404 insert maintain a consistent cutting edge and longer usable life.

Can the insert be used on different holders?
Yes, the ISO CNMG format is standardised; compatibility depends on holder form, clearance angle, tolerance and clamping method, so the insert fits a broad range of ISO CNMG holders.

What advantages does the double-sided chipbreaker provide?
A double-sided chipbreaker offers two usable edges per index, which extends service intervals and improves cost-efficiency while maintaining the expected chip control for medium turning.

Is the 0.4 mm corner radius suitable for finishing?
The 0.4 mm corner radius is a compromise between edge strength and surface finish: it supports acceptable finishing results while providing robustness under varying cutting conditions.
