SCMT120408 AH120 — SCMT 120408 AH120 milling indexable insert for milling by Tungaloy

SCMT120408 AH120 is a square, PVD-coated carbide insert designed for use in Tungaloy milling systems for plan, shoulder, slot, high-feed and contour milling operations.

• PVD-coated carbide grade AH120
• Sharp cutting edge with process security
• Square 90° form with 0.8 mm corner radius
• Cylindrical hole with one-sided countersink

Consistent performance through optimised material and coating

The insert is manufactured from carbide and finished with a PVD-coated surface in the AH120 grade, offering an excellent balance between wear resistance and edge toughness. This composition is especially effective where a sharp cutting edge and consistent machining are required; the coating reduces adhesion and wear at elevated cutting temperatures, while the substrate sustains the mechanical load. The result is fewer interruptions for tool changes and a predictable process window that supports steady production rates and higher overall equipment effectiveness.

Geometry tailored for secure clamping and versatile milling

A square form with 90° cutting angle and 0.8 mm corner radius provides predictable deflection characteristics and a resilient cutting edge for shoulder and face milling. The insert’s cylindrical hole with one-sided countersink (40°–60°) ensures a positive and repeatable seat in compatible cutter bodies; correct seating is essential for vibration damping and consistent cutting depths. For operations that shift between finishing and higher material removal rates, this geometry helps maintain surface quality while offering stable tool life.

Chip control and handling for efficient cycle times

Equipped with a single-sided chipbreaker, the insert manages chip formation across a broad range of feeds and depths, reducing the risk of re-cutting and improving evacuation in peripheral and slot milling. The controlled chip flow lowers thermal load on the cutting edge and assists in maintaining a uniform surface finish. In practical terms, the improved chip behaviour shortens cycle time variability and supports faster downstream handling and inspection.

System compatibility and application guidance

These indexable inserts form part of a modular milling system and require matching of insert seat, geometry and cutter body to function correctly. The insert is intended for Tungaloy milling systems and is applicable to plan, shoulder, slot, high-feed and contour milling depending on the chosen cutter family. When assembled in a correctly specified milling body, the combination of PVD coating, AH120 grade and robust seat design delivers repeatable results and process security across medium to demanding machining tasks.

FAQ

What materials is the SCMT120408 AH120 suitable for?
The SCMT120408 AH120 insert, in PVD-coated AH120 carbide, is designed for general milling tasks and performs well across a broad range of materials where a sharp cutting edge and process security are required.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius balances edge strength and surface finish; it reduces the likelihood of edge chipping compared with smaller radii while still supporting good surface quality in finishing passes.

Is this insert compatible with non-Tungaloy cutter bodies?
The insert is intended for Tungaloy milling systems; compatibility requires matched seat geometry and clamping provisions. For non-Tungaloy bodies, verify seat and clamping conformity before use.

What is the benefit of the single-sided chipbreaker?
The single-sided chipbreaker promotes reliable chip formation and evacuation under varying feeds and depths, which helps maintain consistent cutting conditions and surface quality.

Can the insert handle interrupted cuts?
The AH120 grade is designed for wear and breakage resistance, offering improved robustness in interrupted or semi-interrupted milling compared to less tough grades.
