RDMT 1606ZD AH140 indexable insert for milling — Tungaloy

The RDMT1606ZD AH140 is a PVD-coated cemented-carbide indexable insert engineered for milling applications such as face, shoulder and high-feed operations, requiring a matching seat and cutter body.

• PVD-coated AH140 for wear resistance
• Robust cemented-carbide substrate
• Round 16 mm form with 6.35 mm thickness
• Single-sided chipbreaker for reliable chips
• Cylindrical hole with 40°–60° countersink

Reliable performance for industrial milling operations

The combination of a defined round form and a controlled chip geometry delivers stable cutting engagement and reduced variability in cycle times. Designed for integration into Tungaloy milling systems, this insert ensures the correct contact between the insert seat and cutter body, which in turn maintains machining repeatability and minimises unplanned downtime. The construction prioritises process reliability, enabling shops to standardise holders and inserts across production runs for predictable outcomes.

High edge stability for prolonged productive life

A PVD-coated AH140 grade applied to a hard cemented-carbide substrate provides a balance of wear resistance and edge toughness. The coating reduces adhesive and abrasive wear mechanisms, while the substrate resists chipping under interrupted cuts. This results in a longer effective edge life and fewer indexing cycles. In practical terms, the surface finish and dimensional stability of machined components improve, making the insert a cost-effective choice for volume milling where a sharp cutting edge and process security are required.

Geometry and chip control that simplifies machining

The insert’s single-sided chipbreaker and cylindrical hole with a 40°–60° countersink promote consistent chip formation and evacuation, helping to avoid recutting and reducing heat concentration at the cutting zone. The 15° clearance and a nominal size of 16 mm with a thickness of 6.35 mm produce a secure clamp and stable cutting forces, which supports predictable tool life and surface quality. Clear chip control reduces the need for secondary cleanup and supports higher metal removal rates when paired with appropriate feeds and speeds.

Practical applications and measured benefits on the shop floor

Intended for a wide range of milling tasks — face milling, shoulder milling, slotting, high-feed and contour operations depending on the assigned tool family — this insert brings immediate benefits in terms of repeatability and edge security. Compatibility with Tungaloy milling bodies and the requirement that seat, geometry and milling body match technically ensures the insert performs as specified, delivering consistent surface quality and enabling productivity gains without additional process complexity.

FAQ

Which materials is this insert suited for?
The RDMT1606ZD AH140 insert is a PVD-coated cemented-carbide grade designed primarily for general milling tasks; it performs well across a broad range of common engineering materials when paired with suitable cutting data.

Is the insert compatible with existing Tungaloy milling bodies?
Compatibility requires a matching insert seat and cutter geometry; the RDMT1606ZD AH140 is intended for Tungaloy milling systems where the plattensitz, geometry and milling body are technically aligned.

What benefits does the AH140 coating provide?
The AH140 PVD coating increases wear resistance and improves edge stability under intermittent cutting conditions, which helps to extend the usable life of the insert and maintain surface finish.

How does the chipbreaker influence machining?
The single-sided chipbreaker on this insert supports uniform chip formation and evacuation, reducing recutting and helping to maintain stable cutting temperatures and consistent surface quality.

What should be checked before fitting the insert?
Verify that the insert designation RDMT1606ZD matches the cutter pocket geometry and that clamping screws and any underlay are compatible to ensure secure seating and correct axial position.
