RDMT 1204ZD AH140 RDMT milling insert by Tungaloy — PVD-coated carbide, with cylindrical hole

RDMT1204ZD AH140 is a round indexable milling insert designed for Tungaloy milling systems, intended for face, shoulder, slot, high-feed and contour milling where a sharp edge and process security are required

• PVD-coated carbide grade AH140
• 15° relief angle for secure cutting
• Cylindrical hole with 40°–60° countersink
• One-sided chipbreaker for stable chips

Durable coating and substrate for extended running time

The combination of a PVD-coated cemented carbide substrate and the AH140 grade provides a balance of wear resistance and chipping resistance that supports high‑productivity milling. This composition reduces flank wear and preserves a sharp cutting edge over longer cycle times, which in turn helps to maintain a consistent surface finish and lower tool consumption. The result is measurable process stability and lower total tool cost per component when integrated into a compatible milling cutter.

Geometry engineered for reliable clamping and chip control

The round insert geometry with a cylindrical hole and one-sided countersink (40°–60°) ensures positive location and repeatable clamping in Tungaloy tool bodies; note that plate seat, geometry and cutter body must be technically matched for correct fit. The 15° relief angle and single-sided chipbreaker control chip formation for a predictable evacuation path, reducing the risk of built-up edge and unexpected breakouts. A plate thickness of 4.76 mm and a plate size of 12 mm provide a robust interface between insert and tool body, aiding rigidity in interrupted or high‑feed cuts.

Suited to a wide range of milling operations with clear system benefits

This insert is intended for a variety of milling tasks — from face and shoulder milling to slotting, high‑feed operations and contouring — depending on the assigned tool family. The RDMT1204ZD configuration supports efficient chip control and stable cutting even where repeated indexing is required. Using a grade tailored for milling minimises downtime from insert failure and supports predictable tool change intervals. For production environments demanding repeatability and consistent surface quality, the geometry and coating deliver the operational reliability required for continuous manufacturing.

FAQ

What milling operations is this insert suitable for?
The RDMT1204ZD AH140 milling insert is suitable for face, shoulder, slot, high‑feed and contour milling when used in compatible Tungaloy tool bodies.

How does the AH140 grade affect performance?
The AH140 grade with PVD coating provides high wear and chipping resistance, helping the insert maintain a sharp cutting edge and delivering consistent results across longer runs.

Is a specific cutter body required for these inserts?
The insert seat, geometry and cutter body must be technically matched; the RDMT1204ZD is designed for use in Tungaloy milling systems that accommodate the cylindrical hole and countersink arrangement.

What chip control can be expected from the one-sided chipbreaker?
The single-sided chipbreaker promotes predictable chip formation and evacuation, reducing the likelihood of built‑up edge and improving process stability in interrupted and continuous cuts.

Can the RDMT1204ZD be used in high‑feed milling?
Yes — depending on the assigned tool family, this insert can be applied in high‑feed operations where a sharp edge and robust chip control are required.
