RCMT 1606EN AH725 Tungaloy indexable milling insert — PVD‑coated carbide, round insert with hole for milling

RCMT 1606EN AH725 Tungaloy is an indexable milling insert designed for face, shoulder, slot, high‑feed and contour milling within compatible Tungaloy milling systems

• PVD-coated carbide AH725 grade
• Universal for steel and stainless steels
• Optimised for process security and stability
• Round insert with hole, 6.35 mm thickness

Consistent cutting when machining mixed materials

The PVD‑coated carbide grade AH725 delivers a balance between toughness and wear resistance that is particularly suited to alternating material batches. For workshops that switch between steel and stainless steels, this insert reduces the risk of edge chipping and unexpected breakouts; the engineered chip control and one‑sided breaker help maintain a reliable cutting edge. The result is fewer interruptions, predictable tool life and steadier component quality in series production.

Secure seating and vibration reduction for repeatable accuracy

The round insert with a centred hole and a cylindrical hole style plus one‑sided countersink (40°–60°) ensures precise seating on the cutter body and reliable clamping with the appropriate screw. With a plate thickness of 6.35 mm and a clearance angle of 7°, the geometry promotes stable engagement and lowers vibration during heavy or interrupted cuts. Stable seating improves surface finish and reduces the need for subsequent rework, supporting consistent cycle times on CNC milling centres.

System compatibility and straightforward selection for milling bodies

The RCMT designation indicates the insert geometry and seating form; RCMT1606EN denotes the specific ISO size and edge preparation for the RCMT family. Compatibility of insert seat, geometry and cutter body is essential: the insert must be used in a Tungaloy‑compatible milling body with matching seat and clamping arrangement. Selecting the correct grade and insert shape simplifies tool management and helps to achieve the intended machining strategy with minimal trial and error.

Durable coating and grade for reliable production runs

A PVD surface treatment applied to the AH725 grade provides a hard contact layer that extends edge life under continuous operation while retaining sufficient substrate toughness to withstand variable cutting forces. The combination of coating and substrate yields long tool life and stable performance across small tools and applications with high demands on process security. This reduces tool change frequency and supports a more economical, steady production workflow.

FAQ

What materials is this insert suitable for?
The RCMT1606EN AH725 insert is formulated as a universal, fracture‑resistant grade for machining steel and stainless steels, offering reliable performance when switching between these materials.

How does the insert mount to the milling body?
The insert uses a centred hole with a cylindrical hole plus one‑sided countersink; correct seating and clamping with the matching screw ensure stable fixation in compatible Tungaloy milling bodies.

What are the main advantages of the AH725 grade?
Grade AH725 combines PVD coating and a carbide substrate to deliver a balance of wear resistance and toughness, improving edge life and process security in varied milling applications.

Is the insert suitable for high‑feed milling?
Yes — depending on the assigned tool family and cutter body, the geometry and chipbreaker make the insert suitable for high‑feed operations as well as face and contour milling.

What must be checked before installation?
Ensure the insert designation and seat geometry match the milling body; the RCMT family requires a compatible pocket and clamping arrangement for secure and repeatable performance.
