TNMU1207R2 AH120 indexable milling insert — triangular form, PVD‑coated carbide by Tungaloy

The TNMU1207R2 AH120 is a triangular indexable insert designed for milling operations in compatible Tungaloy milling systems, offering high process security for a range of face, shoulder, slot and contour milling tasks.

• PVD-coated carbide for wear resistance
• Triangular form with 60° cutting angle
• Cylindrical hole with double-sided countersink

Reliable cutting performance for diverse milling tasks

The insert delivers consistently sharp cutting action thanks to its PVD-coated carbide grade AH120, which combines a wear-resistant coating with a robust substrate. This composition supports long edge life and predictable tool behaviour during operations such as face milling and shoulder milling. The insert’s geometry provides a distinct 60° cutting angle, enabling effective engagement in both conventional and high-feed strategies while maintaining surface quality and dimensional control.

Durability and edge stability that reduce interruptions

Designed as a wear- and chipping-resistant grade, the insert features a double-sided chipbreaker which moderates chip formation and evacuation. This reduces the risk of edge chipping under variable cutting loads and helps maintain a steady process window. The resulting reduction in unexpected tool changes improves uptime and contributes to a more economical machining cycle when repeated production runs are required.

System compatibility and clear assembly requirements

Indexable inserts perform reliably only when matched to the correct tool body; therefore, insert seat, geometry and cutter body must be technically compatible. The insert is supplied with a hole and a cylindrical hole plus double-sided countersink (40°–60°) to match secure clamping in Tungaloy milling bodies. Clear notation of seat compatibility prevents mounting errors and ensures the clamping screw and backing components provide uniform support under cutting loads.

Practical machining advantages and recommended conditions

With an inscribed circle of 12 mm and a thickness of 7.94 mm, this insert is suited for medium-duty milling where a sharp edge and process security are priorities. The listed 0° relief angle supports stable cutting engagement and precise profile control, making the insert appropriate for finishing and semi-finishing passes where surface integrity matters. Process planners benefit from the predictable behaviour of the grade, which assists in optimising feeds and speeds for consistent component quality.

FAQ

What types of milling are suitable for this insert?
The TNMU1207R2 AH120 insert is suitable for face, shoulder, slot, high‑feed and contour milling operations when used in compatible Tungaloy milling systems.

How does the AH120 grade affect tool life?
The AH120 PVD coating enhances wear resistance and edge stability, which helps to extend tool life and maintain consistent cutting performance across repetitive production runs.

Is the insert reversible or single‑sided?
This is a double‑sided triangular insert with a double‑sided chipbreaker, allowing multiple usable edges per index to reduce tool costs and changeover frequency.

What clamping requirements apply to this insert?
The insert requires a mating cutter body and clamping screw that match the insert seat geometry; the product features a cylindrical hole with a double‑sided countersink to ensure secure, concentric clamping.

Can this insert be used for high‑speed milling?
The PVD‑coated carbide composition and robust geometry are suitable for higher cutting speeds within the tool and machine limits; machining parameters should be validated on the specific workpiece material and setup.
