CNMG 120408 AH8015 indexable turning insert by Tungaloy — ISO turning insert for general and heat-resistant alloy machining

CNMG 120408 AH8015 is an ISO‑standard indexable insert designed for external and internal turning, offering a balanced combination of wear resistance and edge stability for demanding materials.

• ISO‑standard geometry for holder compatibility
• PVD‑coated carbide grade AH8015
• Double‑sided chipbreaker for versatile cuts
• 0.8 mm nose radius for reliable finish

Consistent cutting performance for heat‑resistant alloys

The PVD‑coated carbide composition of this insert delivers a controlled compromise between wear resistance and edge stability, making it a preferred choice for machining heat‑resistant alloys. The coating improves high‑temperature endurance and reduces adhesive wear during interrupted cuts. For shops focused on repeatable cycle times, the balanced grade supports longer tool life without sacrificing surface quality, resulting in fewer tool changes and steadier production throughput.

Secure fit and ISO compatibility reduce setup errors

Engineered to ISO dimensions, the insert’s form and tolerances ensure predictable compatibility with standard holders. The insert is supplied with a cylindrical hole, enabling positive clamping in many standard external holders or boring bars. Compatibility depends on form, relief angle, tolerance class, fixation method, size and thickness; selecting a holder that matches these parameters simplifies mounting and reduces positional variation during machining, supporting consistent part accuracy.

Efficiency gains from chip control and geometry

The double‑sided chipbreaker geometry facilitates controlled chip formation across a range of feed rates, reducing the risk of entangling chips and improving surface finish. The 0.8 mm nose radius helps achieve a fine external finish while retaining sufficient strength at the cutting edge. Together these features lower cycle interruptions and can contribute to a measurable reduction in per‑part machining time when paired with optimised cutting parameters.

Practical workshop considerations and handling

The insert’s 4.76 mm thickness and rhomboid form deliver sturdy seating and repeatable indexing on double‑sided inserts. Being double‑sided extends usable life by enabling rotation to a fresh edge. Given its designation and AH8015 grade, the insert is particularly well suited to turning operations where a balance of durability and cutting edge robustness is required; maintain correct clamping torque and inspect the seat for wear to preserve repeatable positioning and optimal performance.

FAQ

What materials is this insert best suited for?
The CNMG 120408 AH8015 insert is formulated for general turning and performs particularly well with heat‑resistant alloys, offering a balance of wear resistance and edge stability thanks to its PVD‑coated carbide grade AH8015.

Will this insert fit standard ISO turning holders?
Yes. The insert follows ISO‑standard dimensions; compatibility with a holder is determined by form, relief angle, tolerance class, fixation method, size and thickness, so use holders specified for CNMG‑style inserts.

How does the double‑sided chipbreaker affect performance?
The double‑sided chipbreaker promotes controlled chip formation across various feeds, improving chip evacuation and surface finish while allowing the insert to be indexed to a fresh cutting edge when required.

What does the 0.8 mm nose radius mean for surface finish?
A 0.8 mm nose radius provides a good compromise between robustness and surface quality, enabling finer external finishes without excessively compromising cutting edge strength.

Is the insert suitable for internal turning as well as external turning?
Yes. The ISO‑standard geometry and cylindrical hole enable use in both external and internal turning applications when matched with an appropriate holder.
