CNMG 190612 AH6225 Tungaloy ISO turning insert – rhombic CNMG 80° turning insert

CNMG 190612 AH6225 is a rhombic ISO turning insert optimised for turning applications, offering a balanced combination of a sharp, stable cutting edge and wide applicability for stainless steels in medium-duty machining.

• Universal grade AH6225 for stainless steels
• PVD-coated carbide for durable cutting edge
• 80° rhombic CNMG geometry for turning
• Double-sided chipbreaker, cylindrical hole

Higher process stability and extended edge life for stainless steels

The combination of PVD-coated carbide and the AH6225 grade delivers a durable, wear-resistant cutting edge engineered for the demands of machining stainless steels. The coating improves thermal resistance and reduces adhesion, which in turn stabilises tool life under changing cutting conditions. For production environments where tool-change intervals and surface integrity affect throughput, this insert offers predictable performance that helps lower the cost per component through fewer interruptions and consistent surface finish. The robust design is particularly suitable for medium finishing passes where a sharp but stable edge is required.

Predictable fit and fast indexability reduce downtime

Built to ISO dimensions and the CNMG rhombic form, the insert ensures dependable compatibility with standard external holders and boring bars when form, clearance angle, tolerance class, fastening, size and thickness match. The 80° approach angle and 1.2 mm corner radius deliver a compromise between strength and cutting engagement, reducing deflection on cantilevered setups. The double-sided format allows quick indexing to a fresh cutting edge, shortening machine downtime. A consistent holder–insert system, including clamps and screws matched to the insert thickness of 6.35 mm, supports repeatable seating and secure clamping for stable cutting forces.

Reliable chip control and application guidance for repeatable results

The double-sided chipbreaker designed for this geometry offers controlled chip formation in a range of turning operations, both external and internal, when paired with an appropriately rigid setup. The insert’s cylindrical hole facilitates positive locating in many clamping systems and supports consistent chip flow. For best results, match the chipbreaker and insert grade to the workpiece condition and machining stability; selecting the correct feed and depth of cut will preserve edge life and surface quality. Metav Werkzeuge’s technical consultants can assist with parameter selection and holder compatibility to optimise cycle times and machining reliability.

FAQ

Which materials is this insert optimised for?
The CNMG 190612 AH6225 insert is optimised for stainless steels and similar alloys; the AH6225 grade and PVD coating are intended to reduce adhesion and improve edge life when machining rostfreie Stähle.

How does the CNMG geometry affect turning performance?
The CNMG rhombic form with an 80° approach angle balances access and strength for external and internal turning; the geometry supports stable cutting and predictable insert seating in ISO holders.

What is the benefit of the AH6225 grade with PVD coating?
The AH6225 grade combined with a PVD-coated carbide substrate enhances wear resistance and thermal stability, yielding a sharp, stable cutting edge and longer usable life in medium finishing operations.

Is this insert compatible with common ISO holders?
Yes—CNMG190612 is an ISO-standardised insert; compatibility depends on matching form, clearance angle, tolerance class, fastening, size and thickness to the holder and clamping set.

How should chip control be handled for best results?
Use the double-sided chipbreaker with feed and depth of cut appropriate to the workpiece and setup rigidity; for marginal setups, reduce depth of cut or increase support to maintain consistent chip formation.
