RCMT 1606EN AH140 indexable milling insert (round 16 mm, 6.35 mm) – Tungaloy

The RCMT 1606EN AH140 is a round indexable insert developed for Tungaloy milling systems, delivering a wear- and breakage-resistant cutting edge for face, shoulder, slot and contour milling.

• PVD-coated AH140 carbide grade
• Round insert 16 mm Ø, 6.35 mm thick
• Cylindrical hole with 40°–60° countersink
• Single-sided chipbreaker, 7° relief angle

Increased tool life and consistent machining results

The combination of a PVD-coated AH140 grade and a robust carbide substrate produces reliable performance under continuous milling conditions. The coating reduces flank and crater wear while the substrate maintains a sturdy cutting edge, which leads to fewer index changes and longer service intervals. For production environments where repeatability matters, this technical pairing translates into measurable gains in uptime and component consistency. The insert’s geometry supports a sharp cutting edge that resists chipping during interrupted cuts, improving surface finish with reduced rework.

Secure seating and simple integration into milling systems

Designed for compatibility with Tungaloy milling bodies, the insert requires a matching seat, geometry and clamping system for correct function. The cylindrical hole with one-sided countersink (40°–60°) ensures precise axial positioning, while the standard clamping screw and optional backing pad provide secure fixation during heavy cutting. Correct installation prevents micro-movements that can cause premature wear or unexpected tool failure. The standard round 16 mm form factor and 6.35 mm thickness make it straightforward to fit into many tool families, simplifying inventory and tool management.

Flexible application across common milling tasks

Although the specific tool family determines final cutting strategy, this insert is suitable for a wide range of milling operations including face milling, shoulder milling, slotting, high-feed and contouring when paired with the appropriate cutter body. The single-sided chipbreaker is optimised for controlled chip formation, reducing the risk of built-up edge and improving chip evacuation. This control benefits cycle time and tool life, particularly in mixed production runs where material and cutting conditions vary.

Production efficiency and process security with Tungaloy technology

Choosing a Tungaloy-grade insert means selecting a solution engineered for process stability and repeatable results. The wear-resistant grade reduces unexpected downtime and provides predictable change intervals, aiding planning and costing in production schedules. Combined with Metav Werkzeuge’s availability and consultation services, integration into existing workflows is straightforward and technically supported, making this insert a practical choice for workshops aiming to balance productivity with component quality.

FAQ

What materials is this insert suited for?
The RCMT 1606EN AH140 insert is a PVD-coated carbide grade intended for general milling tasks where a wear- and breakage-resistant cutting edge is required; material-specific suitability depends on the chosen cutter and cutting data.

How does the hole and countersink affect clamping?
The cylindrical hole with a one-sided countersink (40°–60°) provides precise axial location and secure seating when combined with the correct clamping screw and backing pad, ensuring stable fixation during milling.

Which milling operations benefit most from this insert?
Typical uses include face milling, shoulder milling, slotting, high-feed and contour milling when the insert is matched to the appropriate milling body and cutting parameters.

Is the insert compatible with non-Tungaloy tool bodies?
The insert is designed for Tungaloy milling systems; compatibility with other suppliers requires identical seat geometry and clamping specifications to ensure safe and reliable performance.

What feature of AH140 helps reduce downtime?
The PVD-coated AH140 grade offers improved wear resistance and a robust cutting edge, which reduces frequency of index changes and supports predictable tool life, aiding production planning.
