TNMG 110408 AH8015 Turning Insert – PVD‑coated carbide, 60° seat (Tungaloy)

The TNMG110408 AH8015 Tungaloy insert is an ISO‑standard triangular indexable insert designed for external and internal turning of heat‑resistant alloys, offering a balanced combination of wear resistance and cutting‑edge stability.

• TNMG110408 geometry, ISO‑standard 60° seat
• PVD‑coated AH8015 carbide for heat‑resistant alloys
• 0.8 mm corner radius for durable edge life
• Double‑sided insert with cylindrical hole

Proven wear resistance for heat‑resistant alloys

The combination of a PVD coating with the AH8015 cemented carbide substrate delivers consistent performance when machining heat‑resistant alloys. The coating reduces adhesive wear while the substrate provides a good balance between hardness and toughness, which leads to stable chip formation and longer edge life. For production environments that require reliable tool life and reduced changeover frequency, this specification translates into lower tooling costs per part and fewer unscheduled stops, supporting steady process flows.

Geometry and clamping that support versatile turning

The triangular form with a 60° seat and a 0.8 mm corner radius gives both strength at the cutting edge and versatility for finishing and light roughing passes. The insert is double‑sided, enabling economical use of both cutting edges, and the cylindrical hole ensures positive and repeatable clamping in standard ISO holders. With a plate thickness of 4.76 mm and inscribed circle size 11, the insert fits common external and internal turning toolholders; compatibility depends on holder form, relief angle, tolerance class, fixing method, size and thickness, all of which should be checked before assembly to guarantee optimal cutting conditions.

Practical guidance for selection and system setup

Selection of the appropriate chipbreaker and grade should be guided by the workpiece material, machining type and machine‑tool rigidity. The TNMG110408 insert is supplied with a double‑sided chipbreaker, suitable for a broad range of turning tasks; however, choosing the correct chipbreaker profile and cutting parameters will further improve surface finish and swarf control. Typical system setup comprises the ISO indexable insert combined with a matched external holder or boring bar, a shim/packing plate, clamping set and the correct clamp screw; this assembly ensures repeatable positioning and safe cutting performance.

FAQ

What materials is this insert best suited for?
The TNMG110408 AH8015 insert and its PVD‑coated carbide grade are intended primarily for machining heat‑resistant alloys, offering balanced wear resistance and edge stability for general‑purpose turning tasks.

How does the 0.8 mm corner radius influence performance?
A 0.8 mm radius increases edge strength and improves durability under moderate cutting forces, making it suitable for light roughing and finishing where a compromise between strength and surface quality is required.

Is the insert reversible or single‑use per edge?
The insert is double‑sided, allowing the use of multiple cutting edges before disposal, which improves cost efficiency and reduces tool change frequency.

What must be checked for holder compatibility?
Compatibility is determined by insert form, relief angle, tolerance class, fixing method, size and thickness; ensure the holder matches the TNMG110408 geometry, 60° seat and 4.76 mm plate thickness for secure mounting.

Can this insert be used for internal turning?
Yes, the geometry and size make it suitable for both external and internal turning operations when mounted in an appropriate boring bar or holder designed for TNMG inserts.
