SNMG 120416 AH8015 – ISO turning insert for external and internal turning by Tungaloy

SNMG120416 AH8015 is a square ISO turning insert engineered for external and internal turning of heat‑resistant alloys, providing a robust balance between wear resistance and cutting‑edge stability.

• PVD-coated carbide AH8015 for heat-resistant alloys
• Square SNMG form with 90° cutting angle
• 1.6 mm corner radius for reliable edge strength
• Double-sided insert with cylindrical hole for secure clamping

Increased process reliability through optimised grade and coating

The combination of a PVD-coated surface and the AH8015 substrate targets extended tool life when tackling heat‑resistant alloys. The coating reduces abrasive wear and thermal softening at the cutting edge, which translates into longer continuous running times and fewer index changes. For production environments where consistent component tolerance and surface quality matter, this insert offers a predictable wear behaviour and contributes to reduced overall machining costs through fewer tool changes and less downtime.

Stable cutting performance and sensible geometry for demanding cuts

The square SNMG geometry with a 90° cutting angle and a 1.6 mm corner radius provides a stable support zone at the insert tip, assisting in shoulder turning and robust interrupted cuts. A larger corner radius increases edge strength and helps maintain dimensional accuracy under higher feed or interrupted conditions. The double‑sided design doubles the available cutting edges, improving cost‑efficiency per edge without compromising on repeatability or surface finish.

Practical compatibility and setup guidance for straightforward integration

Compatibility with toolholders is determined by insert form, clearance angle, tolerance class, clamping method, size and thickness; the insert’s cylindrical hole ensures secure mechanical locating in commonly used clamping systems. The tool system comprises the indexable insert, a matching outer holder or boring bar, shim/clamp set and replacement screws. Application engineers can advise on selecting the appropriate chipbreaker and grade depending on workpiece stability and feed‑cut conditions, helping to achieve the best compromise between tool life and productivity.

Operational benefits and selection advice for production shops

Using a PVD‑coated carbide grade that is tailored for high temperatures results in less frequent regrinding and a lower rate of scrap caused by edge failure. The grade’s balance between wear resistance and edge toughness makes it suitable as a general‑purpose choice for many heat‑resistant alloys. When choosing a chipbreaker and insert variant, prioritise stability of the setup: a rigid holder and correct clamping reduce vibration, extend insert life and improve surface finish, delivering measurable gains in throughput and process stability.

FAQ

What materials is this insert designed for?
The SNMG120416 AH8015 insert by Tungaloy is crafted for the general machining of heat‑resistant alloys, offering a balance of wear resistance and edge stability suitable for such workpiece materials.

How does the 1.6 mm corner radius affect performance?
A 1.6 mm corner radius increases edge strength, improves dimensional stability in heavier cuts and interrupted machining, and helps maintain surface quality under load.

Is the insert reversible and how many cutting edges are available?
The insert is double‑sided, providing multiple indexable cutting edges and improving cost efficiency per insert compared with single‑edged alternatives.

Which chipbreaker should be selected for best results?
Selection of the chipbreaker depends on the workpiece alloy, feed and depth of cut; for heat‑resistant materials a chipbreaker matching the stability of the setup is recommended—Metav Werkzeuge can advise on the optimal choice.

What must be checked for holder compatibility?
Holder compatibility is governed by insert form, clearance angle, tolerance class, clamping method, size and thickness; ensure the holder matches the SNMG form and the cylindrical hole locating system.
