CNMG 120416 AH6225 ISO turning insert — PVD-coated carbide, 80° (Tungaloy)

CNMG120416 AH6225 is an ISO-standard rhombic insert designed for general external and internal turning of stainless steels and similar alloys

• ISO CNMG 120416 geometry, 80° lead angle
• PVD-coated carbide AH6225 for stainless steel
• Double-sided chipbreaker for stable cutting
• Rhombic insert with cylindrical hole

High-performance grade for variable stainless-steel turning

The CNMG120416 AH6225 insert combines a PVD-coated carbide substrate with a grade developed for stainless steels, delivering a balance between a sharp cutting edge and a robust edge line under varying cutting conditions. The AH6225 grade is tuned for medium-depth turning, offering consistent tool life where conditions change between interrupted cuts and continuous machining. As an ISO-standard turning insert, it simplifies inventory and replacement planning while maintaining predictable performance in production environments.

Geometry and mechanical advantages for secure, repeatable machining

The rhombic CNMG shape with an 80° corner angle provides a versatile approach angle suited to both external and internal turning. The insert is double-sided, which extends effective life per index and reduces tooling costs. A corner radius of 1.6 mm and a thickness of 4.76 mm contribute to edge strength and vibration resistance; the cylindrical hole ensures positive, repeatable seating in compatible holders. For best results, compatibility with a chosen holder should be checked by matching form, clearance angle, tolerance class, fastening method, size and thickness.

Chip control and productivity in everyday production

A dedicated chipbreaker on both rake faces supports controlled chip formation and evacuation, reducing the risk of entanglement and improving surface finish. This stability in chip flow translates into fewer interruptions and higher productive uptime. When combined with a suitable holder, shim and clamping set, the system enables efficient changeover and minimal set-up time in medium-production turning tasks. Selecting the appropriate chipbreaker and grade for the specific workpiece material and cutting parameters is crucial to maximise economy and surface quality.

Understandable technical choices for workshop planners

The insert’s PVD coating forms a thin, hard surface layer that increases wear resistance and maintains edge integrity during elevated cutting temperatures. A 0° clearance specification at the insert’s relief face affects contact conditions and should be considered when matching a holder to avoid rubbing or unintended contact. For users less familiar with insert selection: choose the chipbreaker and grade according to the workpiece material and the intended depth of cut; confirm holder compatibility by checking form, clearance angle, tolerance, fastening and thickness. Metav Werkzeuge can advise on correct holder and screw combinations.

FAQ

What materials is this insert suited for?
The CNMG120416 AH6225 insert is formulated for stainless steels and similar alloys; the PVD-coated carbide provides wear resistance and stability in medium turning operations.

How does the corner radius affect machining?
A 1.6 mm corner radius increases edge strength and reduces vibration, making the insert suitable for stable roughing and medium finishing where a stronger edge is advantageous.

Is this insert reversible and how many cutting edges are available?
The insert is double-sided and indexable; each side provides usable edges consistent with the CNMG geometry, extending life per insert compared with single-sided alternatives.

Which holder features must be checked for compatibility?
Compatibility depends on form, clearance angle, tolerance class, fastening type, size and thickness; match these parameters to ensure secure seating and accurate cutting performance.

What benefit does the PVD coating provide?
The PVD coating adds a hard, wear-resistant layer that improves tool life at elevated temperatures and helps maintain a sharp cutting edge during variable cutting conditions.
