TNMU070308 AH120 Tungaloy indexable insert for milling — PVD-coated carbide, 60°

A TNMU070308 AH120 indexable insert engineered for Tungaloy milling systems, optimised for face, shoulder, slot, high-feed and contour milling.

• PVD-coated carbide for high wear resistance
• 60° triangular geometry for versatile milling
• 0.8 mm corner radius for accurate edge control
• Cylindrical hole with double countersink 40°–60°

Consistent cutting life through optimised coating and grade

The PVD-coated carbide composition in this insert is developed for wear resistance and resistance to edge chipping, offering a stable machining window for interrupted and continuous cuts. The AH120 grade provides a balance between hardness and toughness, which reduces unplanned insert changes and keeps cycle times steady. For production environments where predictable tool life and repeatable results matter, the coated cemented carbide reduces downtime and supports higher process reliability.

Geometry that improves versatility and surface quality

With a 60° geometry and a triangular form, the insert enables multiple edge indexing options, extending usable life per insert. The 0.8 mm corner radius assists in achieving defined edge strength while maintaining good surface finish on shoulders and faces. The double-sided chipbreaker geometry helps control chip formation in a range of feed and depth settings, which simplifies parameter selection and reduces the risk of surface damage. These features together support both roughing and finishing passes with minimal compromise.

Secure seating and easy clamping for system compatibility

The insert is supplied with a cylindrical hole and a double-sided countersink (40°–60°), allowing straightforward mounting in compatible Tungaloy milling bodies. Correct match between insert seat, geometry and cutter body is essential; this specification ensures mechanical stability and repeatable clamping torque. The relatively slim 3.18 mm plate thickness reduces projection while maintaining sufficient rigidity for high-feed operations, provided the toolholder and assembly adhere to the system’s technical requirements.

Application spectrum and recommended use

Designed primarily for milling, the insert suits face, shoulder, slot, high-feed and contour milling operations when paired with the corresponding Tungaloy cutter family. The AH120 variety is particularly suited where a sharp cutting edge and process security are required; its resistance to wear and edge breakouts makes it appropriate for mixed batch production and medium-duty continuous machining. When optimising cycle time, consider the insert’s chip control features and geometry to select feeds and speeds that preserve the edge and the workpiece finish.

FAQ

What milling operations is this insert suitable for?
The TNMU070308 AH120 insert is intended for face, shoulder, slot, high-feed and contour milling when used in the corresponding Tungaloy milling system.

How does the AH120 grade affect tool life?
The AH120 PVD-coated carbide grade provides enhanced wear resistance and improved fracture toughness, which increases predictable tool life under a range of cutting conditions.

Is the insert compatible with non-Tungaloy cutter bodies?
Compatibility depends on exact seat geometry and clamping design; the insert requires a matching seat and secure clamping like those specified for Tungaloy milling systems.

What does the 0.8 mm corner radius mean for surface finish?
A 0.8 mm corner radius balances edge strength and finishing capability, helping to produce smooth shoulder and face surfaces while reducing the risk of edge chipping.

How is the insert secured in the cutter?
The insert features a cylindrical hole with a double-sided countersink (40°–60°) and must be clamped in a correctly matched cutter body to ensure mechanical stability.
