CNMG 120412 AH8015 Turning insert — Tungaloy

CNMG 120412 AH8015 Turning insert for ISO‑standard indexable tool systems, designed for general turning of heat‑resistant alloys with a focus on edge stability and predictable wear behaviour

• ISO rhombic insert, 80° geometry
• PVD‑coated carbide AH8015
• Dual‑sided chipbreaker for versatility
• Cylindrical hole for secure mounting

Consistent cutting geometry for stable metal removal

The CNMG120412 AH8015 insert combines a rhombic 80° geometry with a corner radius of 1.2 mm to provide a robust cutting profile that resists chipping under interrupted cuts and variable feed conditions. The geometry distributes cutting forces across a wider zone of the edge, which improves runout tolerance and reduces vibration when paired with an appropriately rigid holder. For practical terms: the larger corner radius helps preserve the cutting edge during heavy roughing passes while maintaining acceptable surface finish for semi‑finish operations.

Grade and coating engineered for heat‑resistant alloys

The AH8015 grade is a PVD‑coated carbide developed as a first choice for machining heat‑resistant alloys. The coating enhances wear resistance while the substrate maintains sufficient edge stability, creating a balance that extends tool life under elevated cutting temperatures. PVD (physical vapour deposition) thin films reduce adhesive wear and help maintain consistent flank wear progression; this translates into fewer indexings and more predictable component tolerances when machining difficult alloys.

System compatibility and practical handling to reduce downtime

The insert features a double‑sided chipbreaker and a cylindrical hole for screw clamping, enabling easy indexing and secure fixation in ISO‑compatible toolholders. With a thickness of 4.76 mm and a nominal size of 12 mm, the item integrates into standard turning systems where compatibility is governed by shape, relief angle (0°), tolerance class, fastening type and plate thickness. Clear system matching reduces changeover time and helps maintain production flow; when the seat geometry and clamping match the insert, repeatable positioning and reliable chip control follow naturally.

FAQ

What materials is this grade best suited for?
The AH8015 PVD‑coated carbide grade is recommended for general machining of heat‑resistant alloys; the composition balances wear resistance and edge stability for demanding temperatures.

Is the insert indexable and how many usable edges does it offer?
The insert is double‑sided with a chipbreaker on both faces, allowing indexing to a fresh cutting edge when flipped; this provides multiple effective cutting edges per unit.

What does the CNMG120412 designation tell me about size and form?
The CNMG120412 code indicates a rhombic insert with an 80° cutting angle and a nominal size of 12 mm; the product also specifies a corner radius of 1.2 mm and a thickness of 4.76 mm.

How is the insert secured in the holder?
This insert features a cylindrical hole for screw clamping; secure fixation depends on a matching seat geometry, appropriate screw/clamp and compliance with ISO holder specifications.

Can this insert be used for both external and internal turning?
Yes — the design and chipbreaker make it suitable for both external and internal turning operations when paired with the correct ISO‑compatible holder and machining parameters.
