LNMU 0303UE AH8015 indexable insert for milling by Tungaloy — PVD-coated carbide, 90°

The LNMU0303UE AH8015 is an indexable milling insert intended for Tungaloy milling systems, engineered for face, shoulder, slot, high-feed and contour milling where insert seat and geometry must match the milling body.

• PVD-coated carbide substrate
• Suited for heat-resistant alloys
• Cylindrical hole + 40°–60° countersink
• Double-sided chipbreaker design

Higher throughput through balanced wear and edge stability

The AH8015 grade combines a PVD coating with a carbide substrate to balance wear resistance and edge strength, making it a reliable choice for machining heat-resistant alloys. This results in fewer tool changes and more consistent cycle times, which supports stable production runs. The insert’s cutting geometry is tuned to deliver predictable flank wear and maintain surface quality, translating directly into improved process efficiency and lower per-part machining costs.

Secure clamping and repeatable seating for precision

Designed with a cylindrical hole and a double-sided countersink (40°–60°), the insert provides positive seating and dependable clamping in compatible milling bodies. The rectangular form and the 3.18 mm plate thickness ensure robust support under moderate to elevated cutting loads. By ensuring that insert seat, geometry and cutter body are technically matched, the system reduces the risk of vibration and micro-movement, which helps to maintain repeatable component accuracy and prolong cutter life.

Versatile application range with controlled chip formation

The double-sided chipbreaker promotes reliable chip control across a range of operations, from face milling and shoulder milling to high-feed and contour passes, depending on the assigned tool family. For production environments working with temperature-resistant alloys, this insert offers an attractive balance of productivity and predictability. Shops benefit from reduced downtime, consistent surface finishes and an insert geometry that supports safe, continuous cutting at the parameters recommended for the respective milling body.

FAQ

Is the insert compatible with non-Tungaloy milling bodies?
Compatibility depends on the seat and geometry; the LNMU0303UE AH8015 requires a technically matching insert seat and cutter body to ensure correct clamping and performance.

Which materials are best machined with the AH8015 grade?
The AH8015 grade is a PVD-coated carbide selected for machining heat-resistant alloys, offering a balance between wear resistance and cutting-edge stability for these demanding materials.

How does the hole style affect clamping reliability?
The cylindrical hole combined with a double-sided countersink (40°–60°) ensures stable, repeatable seating and improved load distribution when the insert is used in a compatible milling system.

Can this insert be used for high-feed milling operations?
Yes; dependent on the assigned tool family and cutter body, the insert is suitable for high-feed milling as well as face and shoulder operations, offering controlled chip formation.

What are the key dimensions and angles of the insert?
The insert has a plate thickness of 3.18 mm, a plate size designation of 03 and a cutting edge/shoulder angle of 90° with a free cutting angle of 0°.
