CNMG120412 AH8015 ISO indexable turning insert, PVD-coated carbide, 1.2 mm radius — Tungaloy

The CNMG120412 AH8015 is an ISO rhombic indexable insert designed for general turning, offering a versatile solution for machining heat-resistant alloys with emphasis on edge stability and reproducible results

• ISO CNMG 120412 form
• PVD-coated cemented carbide AH8015
• 1.2 mm nose radius for fine finish
• Double-sided chipbreaker for flexibility

Increased productivity through balanced grade performance

The PVD-coated AH8015 grade is engineered as a first-choice solution for the general machining of heat-resistant alloys, providing a well-considered balance between wear resistance and cutting-edge stability. This balance reduces unscheduled tool changes and supports consistent cycle times, making the insert particularly suitable where repeatable component quality and uptime are essential. The coating and substrate combination deliver reliable tool life under varying cutting conditions.

Geometry that secures consistent surface quality

The rhombic ISO geometry with an 80° included angle and a 1.2 mm nose radius contributes to mechanical strength and predictable chip formation; the 0° clearance is optimised for stable contact during external and internal turning. Compatibility with holders depends on form, relief angle, tolerance class, fastening method, size and thickness, which ensures the insert integrates into standard tool systems. This geometry helps achieve improved surface finish and dimensional stability in serial production.

Practical system benefits and economical handling

As an ISO-standardised insert with a double-sided chipbreaker and a cylindrical hole, the component offers economical indexing and straightforward mounting in suitable clamping systems. The 4.76 mm thickness and defined dimensions support secure seating and repeatable clamping; the double-sided design effectively doubles available cutting edges, lowering tooling costs per part. For complex applications or to confirm holder compatibility, Metav Werkzeuge’s technical advisers provide application-oriented support and cutting data.

FAQ

What materials is this insert suitable for?
The AH8015 grade in the CNMG120412 insert is formulated primarily for the general machining of heat-resistant alloys, giving a compromise between wear resistance and edge stability.

How many usable cutting edges does the insert provide?
With a double-sided chipbreaker and its ISO rhombic design, the insert provides multiple indexable edges, enabling economical edge changes and extended tool life.

Is the insert compatible with standard CNMG holders?
Compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness; the CNMG120412 metric sizing follows ISO standards for straightforward matching with appropriate external or internal turning holders.

What surface finish can be expected with a 1.2 mm radius?
A 1.2 mm nose radius supports finer surface finishes while maintaining edge strength; it is a common compromise for general turning where both finish and durability matter.

Can this insert be used for internal turning?
Yes, the insert’s geometry and ISO form make it suitable for both external and internal turning operations when paired with a compatible holder.
