LNMU 0303ZE AH3225 Tungaloy — high-feed milling insert (DoFeed)

LNMU0303ZE AH3225 is an indexable insert for high-feed milling, engineered for large time-chip volumes at small axial depths and suited to pocketing and face-milling operations.

• DoFeed high-feed milling family
• AH3225 PVD-coated carbide grade
• Double-sided chipbreaker geometry
• Cylindrical hole with double countersink (40°–60°)

Maximise removal rates with minimal axial engagement

The DoFeed-series geometry is designed for high-feed milling, allowing a high feed per tooth at very small axial depths. This approach raises the effective material removal rate without increasing axial cutting forces, which benefits cycle times and machine load. The rectangular insert form and 90° cutting angle enable consistent shoulder and pocket milling, while the reduced axial depth improves stability in thin-walled or interrupted cuts. As a result, the machining strategy shifts toward higher productivity with controlled cutting conditions.

Durable edge life through AH3225 and chip control

The AH3225 PVD-coated carbide grade combines wear resistance and edge stability, reducing flank wear and the risk of chipping under demanding high-feed conditions. The double-sided chipbreaker assists chip formation and evacuation, lowering the thermal and mechanical load on the cutting edge. The 0° relief supports a sharp effective cutting edge for precise stock removal. Together, these features translate into longer tool life and more predictable tool-change intervals, improving overall process reliability.

System compatibility and secure clamping for efficient indexing

The insert is supplied in the LNMU0303ZE designation and fits DoFeed-style milling bodies that accept rectangular, size 03 inserts. A cylindrical hole with a double-sided countersink (40°–60°) ensures stable seating and repeatable clamping with standard screws. The 3.18 mm thickness provides a robust contact surface for secure fixation while the double-sided geometry offers economic reuse of the reverse cutting edges. The insert integrates into established milling systems, simplifying inventory and machine setup for series production.

FAQ

What machining tasks is this insert designed for?
The LNMU0303ZE AH3225 insert is intended for high-feed milling operations such as pocketing and face milling where large time-chip volumes are required at small axial depths.

What advantages does the AH3225 grade offer?
AH3225 is a PVD-coated carbide grade offering enhanced wear resistance and edge stability for reduced chipping and longer service life in demanding milling cycles.

How is the insert secured in the milling body?
The insert features a cylindrical hole with a double-sided countersink (40°–60°) and uses standard clamping screws in compatible DoFeed milling bodies to ensure stable and repeatable seating.

Is the insert indexable and economical to use?
Yes; the double-sided geometry permits the use of the reverse cutting edge after indexing, extending usable life and improving cost efficiency for the LNMU0303ZE insert.

Which dimensional and angle specifications are relevant for setup?
Key data: thickness 3.18 mm, size 03, relief angle 0°, cutting angle 90°; manufacturer article number 6782086 identifies the exact item.
