RDMT 1204ZD AH330 round milling insert for milling — Tungaloy

RDMT1204ZD AH330 is a PVD-coated carbide round insert designed for use in Tungaloy milling systems for face, shoulder, slot, high-feed and contour milling.

• PVD-coated AH330 grade for process security
• Round insert Ø12 mm, thickness 4.76 mm
• 15° clearance angle for sharp cutting edge
• Cylindrical hole with one-sided countersink 40°–60°

Consistent cutting performance through a wear‑resistant grade

The AH330 grade is a PVD-coated carbide composition engineered for wear resistance and reduced chipping during milling. The coating stabilises the cutting edge temperature and improves abrasion resistance, which leads to longer in‑service life of the insert and fewer tool changes. This results in higher machine uptime and a predictable tool‑change interval, improving overall process economy and production planning.

Secure clamping and stable engagement for reliable results

A cylindrical hole with a one‑sided countersink (40°–60°) provides positive seating and stable clamping in compatible cutter bodies. The 15° clearance angle supports a sharp cutting geometry that reduces cutting forces and promotes a consistent surface finish. Note that insert seating, geometry and the milling body must match technically; the cutting system comprises the milling body, the indexable insert, the clamping screw and, where applicable, a shim or support washer.

Compact geometry that balances edge life and versatility

The round insert (Ø12 mm, thickness 4.76 mm) supplies multiple cutting edges per index and is suitable for a variety of milling operations depending on the chosen cutter family. The one‑sided chipbreaker helps control chip formation and evacuation during shoulder and contour passes. The small, robust form factor reduces inventory complexity and supports economical machining strategies while maintaining the process security expected from Tungaloy components.

FAQ

What materials can this insert machine effectively?
The RDMT1204ZD AH330 Tungaloy insert is intended for a broad range of milling tasks where wear resistance and edge stability are required; selection of cutting data should follow the specific workpiece material and machining strategy.

How does the AH330 grade improve process security?
The AH330 PVD coating enhances abrasion resistance and reduces edge chipping, which increases reproducibility and tool life when the RDMT1204ZD insert is used in correctly matched Tungaloy milling systems.

Is this insert compatible with any cutter body?
Compatibility requires that the insert seat, geometry and cutter body are technically matching; the RDMT1204ZD form and the specified cylindrical hole with countersink must correspond to the cutter design.

What is the purpose of the one‑sided chipbreaker?
The one‑sided chipbreaker on the RDMT1204ZD supports controlled chip formation for shoulder, face and contour milling, improving surface finish and chip evacuation under the recommended cutting conditions.

Can the insert be indexed to use multiple cutting edges?
Yes, the round geometry of the RDMT1204ZD insert provides multiple usable edges; correct indexing extends effective tool life and reduces tooling costs.
