ACMT 100408 AH140 Wendeplatten - Tungaloy

High-performance, PVD‑coated AH140 grade delivers a sharp cutting edge and extended tool life; the parallelogram 10 mm insert with a 0.8 mm corner radius and secure cylindrical hole with countersink ensures repeatable clamping and precise milling results. Order the insert directly via Metav Werkzeuge or ask our consultants for application matching and availability.

ACMT100408 100408 AH140 – Tungaloy indexable insert for milling

The ACMT100408 AH140 is a PVD‑coated carbide indexable insert designed for face, shoulder, slot, high‑feed and contour milling within compatible Tungaloy milling systems.

• PVD‑coated AH140 carbide grade
• Parallelogram form, 10 mm size
• Cylindrical hole with countersink 40°–60°
• 0.8 mm corner radius, single‑sided chipbreaker

Consistent cutting performance where sharp edges matter

The PVD‑coated AH140 carbide construction provides a balance of wear resistance and edge stability that is particularly beneficial for milling operations requiring a sharp cutting edge and process security. This combination reduces micro‑chipping and helps maintain cutting geometry over longer periods, resulting in more consistent component dimensions and fewer tool changes. The hardened coating also contributes to improved surface finish and predictable tool life under varying cutting conditions.

Secure seating and straightforward integration into milling systems

The insert’s parallelogram form and the cylindrical hole with single-sided countersink (40°–60°) support stable clamping and accurate seat location in matching tool bodies. With a nominal size of 10 mm, a thickness of 4.76 mm and an 85° lead angle, the geometry is geared towards repeatable positioning and reliable chip evacuation when paired with the correct clamping screw and support pad. Compatibility requires the tool body, insert seat and geometry to match technically; proper matching prevents movement under load and preserves cutting performance.

Process stability, productivity and surface quality

A single‑sided chipbreaker combined with the sharp edge behaviour of this grade promotes controlled chip formation in a range of milling tasks, from face milling to high‑feed operations. The 0.8 mm corner radius offers a compromise between robustness and detail capability, enabling stronger corners than smaller radii while still supporting good contour definition. The result is higher uptime and high productivity through fewer interruptions for edge dressing or replacement, alongside reproducible workpiece quality across production batches.

FAQ

What milling tasks is this insert suited for?
The ACMT100408 AH140 insert is suitable for face milling, shoulder milling, slotting, high‑feed and contour milling, depending on the assigned tool body and application parameters.

What are the advantages of the AH140 PVD coating?
The AH140 PVD‑coating increases wear resistance and helps prevent edge chipping, which supports longer tool life and more consistent surface finishes during interrupted or continuous milling.

How critical is seat and geometry compatibility for this insert?
Compatibility is essential: the insert seat, clamping screw and milling body must match the ACMT100408 geometry to ensure secure clamping and repeatable performance in the Tungaloy system.

What does the 0.8 mm corner radius mean for my components?
A 0.8 mm corner radius offers improved robustness over finer radii while still allowing for accurate contouring, helping to balance edge strength with detail in component profiles.

Can this insert be used in high‑speed milling?
The PVD‑coated carbide construction and chipbreaker design allow the insert to perform reliably across a range of cutting speeds; actual cutting parameters should be chosen according to workpiece material and tool body recommendations.
