LNMU 0303ZE AH120 – Indexable insert for high-feed milling (Tungaloy)

LNMU0303ZE AH120 is an indexable insert designed for high-feed milling applications, offering reliable cutting-edge stability for pocket and face milling in a DoFeed system.

• DoFeed series for high-feed milling
• PVD-coated AH120 carbide grade
• Double-sided chipbreaker for secure cutting
• Cylindrical hole with 40°–60° countersink

Increased throughput with DoFeed high-feed technology

The DoFeed model series is engineered for high-feed milling, where large time chip volumes at small axial depths are required. This approach increases the effective material removal rate while keeping axial engagement low, which reduces cutting forces on the toolholder. The insert integrates into a system comprising a milling body, matching indexable inserts and fastening screws, enabling stable machining cycles and consistent component quality. The combination of geometry and grade targets efficient production runs and supports predictable process windows.

Reliable edge life and process security with AH120

The insert’s AH120 grade is a PVD-coated carbide developed for wear resistance and resistance to chipping under interrupted cuts. Its composition and coating maintain a sharp cutting edge, which promotes stable chip formation and reduces heat generation at the cutting zone. For operations that demand uninterrupted throughput and repeatable surface finish, this wear- and breakage-resistant grade supports longer tool life and fewer unscheduled tool changes, translating into improved production consistency.

Practical design for secure mounting and chip control

A rectangular plate with a 3.18 mm thickness and a 0° relief angle provides predictable seating in compatible pockets; the specified 90° seating angle ensures geometric stability in typical cutter bodies. The double-sided chipbreaker promotes controlled chip segmentation during high-feed passes, lowering the risk of adverse chip behaviour. The insert features a cylindrical hole with a double-sided countersink (40°–60°) to allow reliable clamping and alignment within the cutter body, simplifying tool setup and reducing the likelihood of mislocation during index changes.

Typical applications and economic benefits in milling operations

Intended for milling, and particularly suited to pocket and face milling, this insert performs best where axial depths are modest but feed per tooth is elevated. The result is a balance between high productivity and process stability: fewer tool changes, predictable wear progression and reliable surface results. For production environments seeking to improve throughput without compromising repeatability, the DoFeed-compatible insert offers a pragmatic route to higher output and reduced machining cost per component when integrated into a matched tool system.
