CNMG 120408 AH8015 indexable turning insert CNMG120408 120408 for Turning — Tungaloy, PVD-coated carbide, 80°

A CNMG120408 AH8015 indexable turning insert designed for external and internal turning of heat-resistant alloys, offering a balance of wear resistance and edge strength for general-purpose machining.

• PVD-coated carbide AH8015, heat-resistant alloys
• ISO CNMG 120408 rhombic insert with 80° edge
• Double-sided chipbreaker for consistent chip control
• Cylindrical hole, 4.76 mm thickness, 0.8 mm corner radius

Reliable machining performance for demanding alloys

The PVD-coated AH8015 grade provides a balanced combination of wear resistance and edge stability that suits continuous and interrupted cutting in heat-resistant alloys. As a PVD-coated carbide substrate, the insert reduces flank wear and prolongs edge life under elevated temperatures, which translates into longer tool life and fewer indexings. The rhombic geometry with an 80° approach angle ensures stable engagement during both facing and straight turning, maintaining dimensional consistency when cutting less ductile or work-hardened materials.

Consistent chip control and secure clamping raise uptime

Equipped with a double-sided chipbreaker, the insert supports controlled chip formation across a range of cutting conditions, helping to avoid tangling and improving swarf evacuation in bar feed and small-batch production. The cylindrical hole and standard ISO mounting dimensions make the insert straightforward to seat and clamp in compatible holders; correct seat choice and torque ensure repeatable clamping force and minimise vibration. These attributes reduce cycle interruptions and contribute to a predictable production rhythm.

Easy specification and holder compatibility for straightforward integration

The insert conforms to ISO geometry and dimensions (CNMG 120408), simplifying selection of a matching external holder or boring bar. Key dimensions include a nominal size of 12 mm, a plate thickness of 4.76 mm and a corner radius of 0.8 mm, which aids in selecting appropriate feed rates and depth of cut for the required surface finish. With a 0° clearance angle and standard tolerance class, the component integrates into established tool setups without special adaptation, enabling rapid implementation in existing turning cells.

Practical advantages that support cost-effective production

By combining a robust substrate and a PVD layer engineered for stability, the insert helps to maintain cutting-edge geometry over longer operating periods, reducing tooling changes and associated downtime. The balance between toughness and wear resistance offered by the grade is particularly advantageous where mixed batches of alloyed steels and heat-resistant materials are machined, providing a versatile option instead of multiple specialised grades. This versatility supports stock rationalisation and simplified tool management.

FAQ

What materials is this insert best suited for?
The CNMG120408 AH8015 insert is designed primarily for machining heat-resistant alloys and offers a good balance of wear resistance and edge stability for general-purpose alloy turning.

How does the chipbreaker affect performance?
The double-sided chipbreaker on the indexable insert improves chip control and evacuation, reducing swarf issues and supporting consistent cycle times.

Which holders are compatible with this insert?
The CNMG120408 geometry follows ISO standards, so compatible CNMG external holders and boring bars that accommodate a 12 mm ISO CNMG insert and a cylindrical locating pin will be suitable.

What are the key dimensions to consider when setting cutting data?
Important values include the 12 mm nominal size, 4.76 mm thickness and 0.8 mm corner radius; these influence feed rates, depth of cut and expected surface finish.

Is the insert reversible or single-use?
The insert is double-sided, allowing indexing to a fresh cutting edge once the active edge reaches wear limits, which extends effective tool life.
