CNMG120404 AH8015 indexable turning insert by Tungaloy — PVD-coated carbide, 0.4 mm nose radius

CNMG120404 AH8015 is an ISO-standard, rhombic indexable insert designed for general turning of heat-resistant alloys and similar materials.

• PVD-coated carbide AH8015
• 0.4 mm nose radius for fine finishing
• Double-sided chipbreaker, rhombic form
• ISO CNMG 120404 — 80° geometry, cylindrical hole

Higher output through balanced grade and coating

The PVD-coated AH8015 grade combines carbide substrate strength with a wear-resistant surface layer, delivering a balance between wear resistance and cutting-edge stability. For the general machining of heat-resistant alloys, this balance reduces flank wear and maintains edge geometry over longer cycles, which translates to fewer interruptions for insert changes and improved process throughput. The integrated double-sided chipbreaker supports predictable chip formation across common turning operations, lowering the risk of workpiece damage and facilitating uninterrupted production runs.

Precise fit and predictable performance with ISO compatibility

As an ISO-designated CNMG insert, the geometry and mounting features ensure repeatable seating in compatible holders. Key dimensions include a 0.4 mm nose radius, 4.76 mm thickness and 12 mm insert size, with an 80° cutting angle and a 0° clearance (free) angle; the plate is rhombic and supplied with a cylindrical hole for secure fastening. These measurable parameters enable selection of the correct toolholder and clamping set: compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness. The double-sided design also means two usable cutting edges per index, improving cost efficiency per edge compared with single-sided formats.

Operational advantages and best-practice handling

Using a grade optimised for demanding alloys leads to improved surface finish and longer tool life, especially when machining at the recommended cutting data for the material. The insert’s PVD coating enhances resistance to built-up edge and thermal softening, while the CNMG geometry offers a reliable corner strength for both roughing and finishing steps. Changing the indexable plate is straightforward with the correct holder and clamping kit, allowing rapid restoration of cutting performance and short machine downtime. For reliable selection of chipbreaker and cutting parameters according to workpiece material and operation stability, consult the technical advisors to match holder and insert combinations precisely.

FAQ

What materials is this insert best suited for?
The CNMG120404 AH8015 Tungaloy insert is intended primarily for the general machining of heat-resistant alloys, offering a compromise between wear resistance and edge stability for such materials.

How many cutting edges are available per insert?
The indexable plate is double-sided, providing two usable cutting edges for each index, which increases cost-effectiveness compared with single-sided alternatives.

Which dimensions determine holder compatibility?
Holder compatibility is defined by the insert form, clearance angle, tolerance class, fastening method, size (12 mm) and thickness (4.76 mm); the 80° geometry and cylindrical hole are also decisive.

Can the grade AH8015 withstand elevated cutting temperatures?
Yes, the AH8015 grade, with its PVD coating, is selected as a first choice for machining heat-resistant alloys and is designed to resist thermal softening and reduce built-up edge.

Is the CNMG geometry suitable for both roughing and finishing?
The CNMG rhombic form with a 0.4 mm nose radius offers sufficient corner strength for roughing operations while still allowing fine finishing, provided appropriate cutting parameters are applied.
