SCMT120408 AH6225 indexable insert for milling, 90° by Tungaloy

SCMT120408 AH6225 is a square indexable milling insert designed for milling operations where a sharp, stable cutting edge and reliable performance in stainless steels are required

• PVD-coated carbide AH6225 for stainless steels
• Square insert 12 x 12 mm, thickness 4.76 mm
• Cylindrical hole with single-sided countersink 40°–60°
• 7° clearance angle, 0.8 mm corner radius

Precision and performance for demanding stainless‑steel milling

The SCMT120408 AH6225 Tungaloy insert is engineered to combine a PVD-coated carbide grade with a geometry that supports both edge sharpness and stability. This results in a cutting edge that sustains consistent chip formation when machining stainless steels, reducing vibration and minimising workpiece distortion. The insert’s square form and robust thickness provide contact stability in the pocket, while the single-sided chipbreaker directs chips efficiently to preserve tool life and surface finish. This technical combination means fewer tool changes and predictable component tolerances in serial production.

Compatibility and ease of integration into milling systems

Designed for use in Tungaloy milling systems, the insert requires a matching pocket geometry, clamping screw and, where applicable, a supporting shim to ensure proper seating. The cylindrical hole with a single-sided countersink (40°–60°) guarantees secure clamping and repeatable positioning during index changes. With a 7° clearance angle and 0.8 mm corner radius, the insert suits face, shoulder, slot, high-feed and contour milling applications depending on the chosen cutter body. This compatibility reduces setup time and enables rapid integration into existing tool inventories while maintaining cutting stability across varied operations.

Efficiency, reproducibility and quality of finish

The AH6225 grade is a versatile PVD-coated option optimised for a wide range of stainless steels, balancing wear resistance and edge toughness. The PVD coating enhances resistance to built-up edge and thermal softening, allowing for stable performance under fluctuating cutting conditions. As a result, the insert contributes to a consistent surface finish and repeatable dimensional accuracy, supporting higher process uptime and a favourable cost-per-part equation. For production runs where process reliability and predictable tool life matter, this insert offers a pragmatic compromise between economy and performance.

FAQ

What materials is this insert suitable for?
The SCMT120408 AH6225 insert is specified for stainless steels, the AH6225 grade providing a balance of edge toughness and wear resistance suitable for varied stainless‑steel applications.

How is the insert secured in the cutter body?
The insert features a cylindrical hole with a single-sided countersink (40°–60°) to match standard clamping screws and ensure repeatable seating in compatible Tungaloy milling bodies.

Can this insert be used for high-feed milling?
Yes, depending on the assigned cutter family and machining strategy, the insert is suitable for high-feed milling as well as face, shoulder and contour operations.

What benefits does the PVD coating provide?
The PVD coating enhances thermal and adhesive wear resistance, reduces built‑up edge on stainless‑steel workpieces and helps maintain a sharper cutting edge under variable conditions.

Is the corner radius suitable for finishing?
The 0.8 mm corner radius offers a compromise between strength and edge definition; it supports good surface quality while providing robustness against edge chipping during interrupted cuts.
