RPMT 1204EN AH4035 – Tungaloy milling indexable insert, PVD-coated, round 12 mm

The RPMT1204EN AH4035 is a PVD-coated cemented carbide indexable insert for milling, engineered for wear- and chipping-resistant cutting in diverse face, shoulder, slot and contour operations

• PVD-coated carbide AH4035 for safe performance
• Sharp cutting edge with wear and chipping resistance
• Round 12 mm insert with 4.76 mm thickness
• 11° clearance and single-sided chipbreaker
• Cylindrical hole with 40°–60° countersink

Consistent machining through a wear‑resistant grade

The AH4035 grade combines a PVD coating with a tough cemented carbide substrate to deliver enhanced resistance to abrasion and edge chipping; this results in longer effective life of the cutting edge and fewer unplanned index changes during production. For milling tasks where a sharp edge and process security are essential, the coated grade supports stable cutting temperatures and improved surface finish, reducing rework and downtime while maintaining repeatable results.

Geometry that secures tooling and simplifies set‑up

A round 12 mm profile with a thickness of 4.76 mm and an 11° clearance ensures predictable engagement with compatible Tungaloy milling bodies. The insert’s cylindrical hole with a one‑side countersink (40°–60°) provides reliable seating and clamp support, which helps to reduce micro‑movement and vibration at the tool–workpiece interface. The single‑sided chipbreaker aids chip control for common milling feeds, improving evacuation and reducing heat concentration at the cutting edge.

Versatile application scope and process benefits

Designed for a range of milling operations—face, shoulder, groove, high‑feed and contour milling depending on the associated tool family—this indexable insert supports machining of many common workpiece materials where a robust edge and reliable cutting performance matter. The PVD finish assists in high‑speed conditions and contributes to consistent surface quality. For questions on compatibility with specific milling bodies or recommended cutting data, Metav Werkzeuge offers application support and technical data to match the insert to the machining task.

FAQ

What materials is this insert suitable for?
The RPMT1204EN AH4035 insert is a PVD‑coated cemented carbide grade designed for a broad range of materials commonly encountered in milling; its wear resistance and edge stability make it suitable where process security is required.

How does the AH4035 grade improve tool life?
AH4035 combines a wear‑resistant substrate with a PVD coating to reduce abrasive wear and chipping, so the insert maintains cutting performance longer under typical milling conditions.

What clamping features ensure secure seating?
The insert has a cylindrical hole with a single‑side countersink (40°–60°) that, together with the round form and specified thickness, provides secure seating and consistent clamping in the correct Tungaloy tool body.

Is this insert compatible with all milling bodies?
Compatibility requires that the insert seat, geometry and cutter body are technically matched; the RPMT1204EN must be used in Tungaloy milling systems or equivalent bodies that accept the RPMT form and 1204EN designation.

What benefits does the single‑sided chipbreaker provide?
The single‑sided chipbreaker improves chip control for typical feed ranges, aiding evacuation and reducing recutting, which contributes to temperature control at the cutting edge and consistent surface finishes.
