Reliable grade for longer tool life and steady process security

The AH130 grade is a PVD-coated carbide developed for demanding milling conditions where a sharp, durable cutting edge and resistance to chipping are essential. This combination supports stable chip formation and reduced edge wear, which in turn lowers the risk of unplanned interruptions and rework. By choosing a grade that balances toughness and hardness, shops achieve higher process security and can extend indexable insert change intervals without sacrificing surface quality or dimensional repeatability.

Geometry and clamping that ensure repeatable accuracy

With a round 12 mm form and a 4.76 mm plate thickness, the insert delivers consistent engagement with the workpiece and predictable cutting forces. The 11° relief angle optimises the rake and clearance geometry for a secure cutting action, while the cylindrical through-hole with a single-side countersink (40°–60°) ensures precise clamping and repeatable seating in compatible cutter bodies. Correct matching of insert seat, geometry and cutter body guarantees repeatable tool runout and, consequently, predictable part quality.

Coating and material engineered for milling productivity

The combination of a robust carbide substrate and a PVD surface treatment provides low friction, enhanced thermal resistance and improved wear behaviour during intermittent and continuous cuts. These material properties reduce cutting forces and help maintain a sharp cutting edge for longer, which benefits cycle time and reduces consumption of inserts per production batch. For operations that demand both efficiency and consistent surface finish, this composition is particularly effective.

Application spectrum, chip control and system compatibility

Intended for a broad range of milling tasks — including face, shoulder, slot, high-feed and contour milling depending on cutter family — the insert features a single-sided chipbreaker that aids controlled chip formation and evacuation. It is supplied for use in Tungaloy milling systems where insert seat, geometry and cutter body are technically matched; proper system pairing is essential for safe and effective operation. Handling and storage are straightforward: keep inserts in their original packaging until assembly and verify compatibility with the milling body before use to secure optimal performance.

FAQ

What materials is this insert suitable for? The RPMT1204EN AH130 insert is a carbide tool with a PVD coating designed for a wide range of milling applications; its properties favour steels and mixed materials where good chip control and edge stability are required.

How does the AH130 grade improve process reliability? AH130 offers enhanced resistance to chipping and wear; when used in compatible milling systems, the grade contributes to consistent chip formation and longer effective tool life for the insert.

Does the insert require a special cutter body? The insert must be used in a milling body with a matching seat and geometry; the RPMT1204EN designation indicates the geometry and hole style that the cutter body must accommodate.

What benefit does the through-hole and countersink provide? The cylindrical through-hole with a single-side countersink (40°–60°) enables secure clamping and repeatable seating, which improves runout control and maintains consistent cutting conditions.

Can this insert be used for high-feed milling? Yes — depending on the selected cutter family and operational parameters, the geometry and grade are suitable for high-feed as well as face, shoulder and contour milling.
