RDMT 1204ZD AH120 — indexable milling insert for milling (Tungaloy)

RDMT1204ZD AH120 indexable insert for secure, high-reliability milling in compatible Tungaloy systems

PVD-coated AH120 grade for milling Round 12 mm insert for versatile mounting 4.76 mm thickness, 15° relief Cylindrical hole with single-side countersink

Outstanding wear resistance and consistent cutting performance

The PVD-coated cemented carbide composition of this insert delivers a balance between toughness and edge stability that reduces unplanned tool changes. The AH120 grade is specified for applications where a sharp cutting edge and high process security are required; this leads to more predictable flank wear and fewer interrupted cycles. When used in appropriate milling bodies, the insert supports steady metal removal rates and helps maintain dimensional accuracy across longer production runs.

Clear fitment and secure clamping for repeatable results

Compatibility is crucial: the insert seat, geometry and milling cutter must match exactly for safe operation. The round form with a 12 mm diameter and 4.76 mm thickness provides straightforward seating, while the one-sided chipbreaker helps direct chips reliably. The central cylindrical hole with a single-sided countersink (40°–60°) ensures stable clamping in tool bodies designed for this style of insert, reducing the risk of micro-movements and improving repeatability in serial machining.

Broad milling applications with process-focused design

This indexable insert is intended for a range of milling tasks including face, shoulder, slot, high-feed and contour milling, depending on the assigned cutter family. The combination of a sharp edge geometry and AH120 wear properties offers an advantage when machining materials that demand both edge integrity and consistent chip formation. Selecting the insert as part of a matched Tungaloy system simplifies tool selection and supports efficient production planning with fewer changeovers.
