RCMT 1204EN AH120 indexable insert for milling — Tungaloy

The RCMT1204EN AH120 indexable insert is a PVD-coated carbide cutting element engineered for Tungaloy milling systems, suitable for face, shoulder, slot, high-feed and contour milling.

• PVD-coated carbide grade AH120
• One-sided chipbreaker geometry
• Round 12 mm insert, 4.76 mm thickness
• Cylindrical hole with 40°–60° countersink

Stable cutting edge for consistent production results

The PVD-coated carbide grade AH120 combines wear resistance with a design optimised to resist edge chipping, delivering process security in interrupted and continuous cuts. The coating improves thermal resistance and wear behaviour, which results in fewer edge changes and more predictable tool life. For production environments where surface finish and repeatability matter, this chemistry and microstructure reduce downtime and support tighter tolerances without complex adjustments.

Geometry tailored to versatile milling tasks

A round insert with a diameter of 12 mm and a plate thickness of 4.76 mm offers flexibility across a range of milling operations. The one-sided chipbreaker promotes controlled chip formation and evacuation, reducing the risk of built-up edge and improving surface quality. The insert features a 7° relief angle and a central cylindrical hole with a one-sided countersink (40°–60°) for secure clamping; correct seating and geometry matching with the cutter body are essential for optimal performance. These geometric details suit face, shoulder and contour milling when matched to the appropriate milling body family.

Practical integration and reliable system behaviour

The insert is intended for use in a complete system comprising milling body, indexable insert, clamping screw and, where required, a shim or backing plate. The RCMT format ensures simple indexing and replacement, while the central hole and countersink provide a stable mechanical interface that maintains repeatable positioning after insert changes. Compatibility with Tungaloy milling bodies should be verified by matching the seating form and geometry; the manufacturer article number 5812595 and SKU TUN5812595 identify the exact item for procurement and inventory control. Where process security and reduced variability are priorities, this insert supports efficient manufacturing workflows.

FAQ

What materials is this insert suited for?
The RCMT1204EN AH120 insert is a PVD-coated carbide grade designed primarily for general milling tasks; material suitability depends on the chosen cutting data and the associated milling body.

How does the chipbreaker influence performance?
The one-sided chipbreaker on the insert promotes controlled chip formation and evacuation, improving surface finish and reducing the likelihood of built-up edge during milling operations.

What must be checked before fitting the insert?
Compatibility of the insert seating, geometry and the milling body is required; ensure the seat and clamping arrangement match the RCMT1204EN designation and the clamping screw is correctly torqued.

Is the RCMT1204EN AH120 available with other coatings or grades?
This listing specifies the AH120 PVD-coated grade; alternative grades or coatings may be available from the manufacturer for different process requirements.
