ACMT100408 AH120 – milling indexable insert, parallelogram form, 0.8 mm radius | Tungaloy

The ACMT100408 AH120 is a PVD-coated carbide indexable insert for milling, designed for use in compatible Tungaloy milling systems where insert seat, geometry and body match to ensure reliable clamping and optimal cutting performance.

• PVD-coated carbide for wear resistance
• Optimised for process-safe milling
• Parallelogram form for versatile cutting
• 0.8 mm corner radius for precision
• Cylindrical hole with single-sided countersink

High-efficiency cutting with wear-resistant grade

The insert's AH120 grade and PVD coating combine to provide improved edge stability and wear resistance during continuous milling. This results in predictable tool life and fewer unscheduled tool changes, which contributes to higher uptime on the shop floor. The description of the coating and carbide explains why cutting edges remain sharp: PVD creates a thin, hard layer that reduces adhesion and wear, while the cemented carbide substrate sustains mechanical strength under load. These technical choices translate directly into cost-efficiency and consistent part quality for series production.

Secure seating and versatile system compatibility

Designed for use in Tungaloy tool families, the insert requires matching of insert seat, geometry and milling body to achieve correct clamping and torque transmission. The insert comes with a cylindrical hole and a single-sided countersink (40°–60°) to suit common clamping screws and locational features; the parallelogram shape aids in positional flexibility for different tool holders. The 85° principal cutting face and the 7° relief angle support robust engagement in shoulder and plane milling, while the 4.76 mm plate thickness and 10 mm nominal size ensure mechanical stability when mounted.

Precision contouring and reliable edge life

A 0.8 mm corner radius balances sharpness and strength: small enough to achieve accurate contours and fine shoulder finishes, yet large enough to avoid premature chipping under moderate feed rates. This geometry is particularly suited for finishing passes, contour work and high-feed applications where a consistently sharp edge and process security are required. The one-sided chipbreaker design assists in stable chip formation and evacuation, reducing the risk of built-up edge and improving surface finish on a range of materials.

Practical benefits for production workflows

Using this PVD-coated carbide insert in a compatible milling system reduces setup variation and simplifies tool management: consistent wear behaviour means fewer adjustments to feeds and speeds over a tool's life. The combination of stable chip formation, robust cutting edge and standardised hole/countersink dimensions supports predictable performance in planing, shoulder, slot and contour milling. For production environments aiming for repeatability and high throughput, the insert offers a balance of productivity and component quality that aligns with modern machining demands.

FAQ

What milling operations suit this insert best?
This insert is intended for a wide range of milling tasks: planing, shoulder milling, slotting, high-feed and contour work when used in the appropriate Tungaloy milling bodies.

Which materials can be machined with this grade?
The AH120 PVD-coated carbide grade is designed for wear- and fracture-resistant milling across a broad material spectrum, providing stable edge life and good process security.

How does the 0.8 mm corner radius affect finish and strength?
A 0.8 mm radius provides a compromise between a sharp cutting edge for fine finishes and sufficient strength to resist edge chipping, making it suitable for finishing and contouring passes.

Is this insert compatible with existing Tungaloy tool families?
Compatibility requires matching the insert seat, geometry and milling body; the insert's hole and countersink conform to common clamping arrangements but verification against the specific holder family is recommended.

What does the PVD coating provide compared with uncoated grades?
The PVD coating reduces flank and crater wear, lowers adhesion tendencies and extends edge life under continuous cutting, resulting in more consistent tool performance.
