RDMW 1606ZD AH140 milling insert – PVD-coated carbide, round 16 mm, for Tungaloy systems

RDMW1606ZD AH140 is a PVD-coated carbide indexable insert designed for milling operations where a sharp cutting edge and high process security are required.

• PVD-coated AH140 grade
• Round 16 mm insert for milling
• 15° relief angle for positive cutting
• Cylindrical hole with one-sided countersink

Consistent performance through advanced coating and substrate

The combination of the AH140 PVD coating and a carbide substrate provides a stable cutting edge that reduces flank wear and resists chipping under interrupted cuts. The result is longer tool life and fewer insert changes, which increases effective machine uptime and lowers unit costs per workpiece. The applied coating improves heat resistance and adhesion, so edge integrity is retained even during demanding milling tasks.

Secure clamping and system compatibility for reliable operation

The insert is part of a system where plate seat, geometry and cutter body must match precisely; this ensures correct positioning and repeatable clamping force. The cylindrical hole with a one-sided countersink (40°–60°) facilitates positive screw engagement and stable seating, reducing micro-movement that can cause premature edge failure. With a 6.35 mm thickness and round 16 mm form, the component is compatible with specified Tungaloy milling bodies, delivering consistent axial and radial support during face, shoulder and contour milling.

Broad application range and machining advantages explained

Suitable for face, shoulder, slot, high-feed and contour milling depending on the assigned tool family, this insert supports a variety of strategies. The 15° relief angle gives a positive cutting geometry for reduced cutting forces and improved surface finish on many materials, while the PVD-coated surface reduces adhesion of built-up material. For users less familiar with coatings: PVD (physical vapour deposition) forms a thin, hard layer that enhances wear resistance without significantly changing the substrate toughness, so the insert keeps a sharp edge and predictable wear behaviour across batch production.

FAQ

What materials is this insert suited for?
The RDMW1606ZD AH140 insert is designed for general milling tasks where a PVD-coated carbide performs well; material suitability depends on the specific cutter body and machining parameters chosen.

How does the AH140 grade improve process security?
AH140’s PVD layer enhances edge stability and wear resistance, so the insert offers reliable cutting behaviour and reduced risk of edge chipping in interrupted or mixed-cut operations.

Is a matching milling body required for correct use?
Yes, correct function requires a milling body with compatible seat and geometry; the insert’s mounting features — cylindrical hole with countersink — ensure secure clamping when paired with the appropriate Tungaloy cutter.
