SDMT 1204PD AH120 square milling insert for high-process security — Tungaloy

SDMT1204PD AH120 is a square indexable insert designed for milling applications where a sharp cutting edge and consistent process security are required.

PVD-coated carbide grade AH120
High wear and chipping resistance
Square insert 12 mm, 4.76 mm thickness
Cylindrical hole with 40°–60° countersink

Improved uptime through a wear-resistant cutting edge

The PVD-coated AH120 carbide composition delivers a combination of wear resistance and edge stability that supports longer tool life and fewer interruptions for insert changes. The coating reduces thermal and abrasive wear, meaning the insert maintains a sharp cutting edge for an extended period under typical milling conditions. For manufacturers seeking predictable tool life and reduced machine downtime, this translates into steadier throughput and lower operational disturbance.

Secure seating and accurate clamping for consistent surface finish

The square format with a cylindrical hole and a single-sided countersink (40°–60°) ensures reliable clamping in compatible milling bodies. The specified 90° cutting angle and 15° clearance angle provide defined geometry for shoulder and slot milling operations. When seat geometry, insert form and cutter body match, the result is reduced vibration and improved dimensional repeatability — a direct benefit for components demanding consistent surface quality and tight tolerances.

Process-ready design for a range of milling operations

Engineered for plan, shoulder, groove, high-feed and contour milling as assigned by the corresponding tool family, this insert features a single-sided chipbreaker and a sharp edge form that promotes stable chip formation and evacuation. The combination of substrate and coating is aimed at avoidance of edge chipping under demanding cutting forces, supporting secure production in industrial settings. In systems where plate seat, geometry and cutter body are aligned, the insert contributes to predictable machining cycles and reliable component output.

FAQ

What materials is this insert intended for?
The SDMT1204PD AH120 insert from Tungaloy is formulated as a wear- and chipping-resistant solution for general milling tasks; specific material compatibility should be confirmed against machining parameters and toolbody selection.

How critical is matching the insert to the cutter body?
Correct match of insert seat, geometry and cutter body is essential for secure clamping and optimal performance with the SDMT1204PD AH120; mismatched components can reduce process security and surface quality.

Can the insert be used for high-feed milling?
The geometry and chip control of this indexable plate support a range of milling operations including high-feed milling when assigned to the appropriate tool family and machining setup.

What advantages does the PVD coating provide?
The PVD coating on the AH120 grade improves thermal and abrasive resistance, helping to maintain a sharp cutting edge and to reduce flank and crater wear during sustained milling cycles.

Is there a specific clamping screw or underlay required?
The system comprises the milling body, indexable insert, clamping screw and, where relevant, a support pad; correct interface components must be used to ensure the SDMT1204PD functions reliably.
