SDMT 1204AF AH120 indexable insert for milling — Tungaloy

SDMT1204AF AH120 Tungaloy insert for Tungaloy milling systems, engineered for face, shoulder, slot, high-feed and contour milling where a sharp edge and consistent process security are required.

• PVD-coated carbide AH120 for high wear resistance
• Square 12 mm format with 90° cutting angle
• Cylindrical hole with one-sided 40°–60° countersink
• Zero corner radius, single-sided chipbreaker

Reliable cutting performance through PVD-coated carbide

The PVD-coated AH120 grade is a wear- and chipping-resistant carbide formulation developed for demanding milling tasks. With a PVD coating, the cutting edge resists abrasion and maintains sharpness over longer cycles, which reduces tool-change frequency and contributes to consistent component quality. This results in improved process stability and predictable tool life, particularly in interrupted cuts and mixed-material production where edge integrity is critical.

Geometry optimised for versatile milling applications

The square plate in 12 mm size with a 90° cutting angle and a 15° relief angle provides a sturdy geometry for face and shoulder operations. The plate thickness of 4.76 mm and a corner radius of 0 mm ensure a robust edge for heavy engagement and precise corner finishing. These dimensional choices support both moderate and higher feed milling families, delivering reliable metal removal rates while preserving dimensional accuracy on the workpiece.

Secure mounting and controlled chip formation

A cylindrical hole with a one-sided 40°–60° countersink enables secure clamping and consistent seating in compatible cutter bodies; insert seat, geometry and cutter body must match to guarantee correct fixation. The single-sided chipbreaker design promotes stable chip formation and evacuation in a wide range of steels and non-ferrous alloys, reducing recut and improving surface quality. Clear system compatibility reduces setup time and lowers the risk of incorrect assembly.

Practical productivity advantages on the shop floor

Intended for milling, this insert supports plan, shoulder, slot, high-feed and contour operations depending on the chosen cutter family. The combination of a sharp, wear-resistant edge and compact geometry helps maintain cycle-time targets and lowers overall tooling cost through extended service intervals. The insert is suitable for job shops and production environments that prioritise repeatable results and minimal process interruptions.

FAQ

What applications is this insert suitable for?
The SDMT1204AF AH120 insert is designed for face, shoulder, slot, high-feed and contour milling when used in the appropriate Tungaloy milling cutter family.

How does the AH120 coating improve performance?
The PVD-coated AH120 carbide extends edge life and reduces wear, so the SDMT1204AF AH120 Tungaloy insert maintains a sharper edge for longer under milling conditions.

Is the insert compatible with non-Tungaloy cutter bodies?
Compatibility requires matching the insert seat, geometry and cutter body; the SDMT1204AF AH120 insert should be used in systems that conform to the same seat and clamping standards.

What are the mounting details for secure clamping?
The insert features a cylindrical hole with a one-sided 40°–60° countersink for stable clamping when paired with the correct clamp screw and possibly a shim.

Can this insert be used for high-feed milling?
When combined with a suitable high-feed cutter family, the geometry and robust carbide grade of the SDMT1204AF AH120 insert can support high-feed strategies and productive metal removal.
