LNMU 0303ZE AH130 indexable insert for milling — Tungaloy

The LNMU 0303ZE AH130 is a rectangular, PVD‑coated indexable insert designed for high‑feed milling in pocket and face operations, supplied for integration into DoFeed milling systems.

• DoFeed high‑feed geometry for fast material removal
• PVD‑coated AH130 grade for wear resistance
• 0° relief with 90° lead for stable cutting
• Cylindrical hole with double countersink (40°–60°)

Maximise metal removal with DoFeed high‑feed geometry

The DoFeed family is engineered for large time‑chip volumes at small axial depths, enabling significantly higher feed per tooth without compromising surface quality. This indexable insert delivers shorter cycle times in pocket and face milling by allowing higher table feed rates while maintaining low cutting forces. For production environments where throughput and predictable machining times are priorities, the DoFeed design reduces idle time and supports a more efficient tool‑path strategy, translating directly into improved shopfloor productivity.

Secure cutting performance from the AH130 grade

The AH130 grade is a PVD‑coated, wear‑ and chip‑resistant cemented carbide developed for milling applications that require a sharp cutting edge and reliable process security. The coating reduces flank and crater wear while the substrate resists chipping under interrupted cuts. Together, these properties yield consistent edge life and steady component quality, lowering rework rates. The insert’s 0° relief and 90° lead angle contribute to predictable engagement with the workpiece, which is particularly beneficial during high‑feed passes where edge stability directly affects finish and tool life.

Practical mounting and geometry for repeatable results

The rectangular 03 format with a 3.18 mm thickness and a cylindrical hole with double‑sided countersink (40°–60°) ensures secure clamping in compatible DoFeed cutters and simplifies handling during index changes. The double‑sided chipbreaker geometry supports efficient chip formation in common milling conditions, reducing the risk of built‑up edge and improving evacuation. These design features make tool management straightforward: inserts are simple to store, identify and replace, helping to maintain uptime and reduce process variability across shifts and operators.

Integration into production and process advice

When integrating this insert into an existing milling system, pair it with the matching DoFeed cutter bodies and recommended screw types to maintain clamping integrity and repeatable runout. The insert is optimised for pocket and face milling strategies typical in general machining and production runs, offering a balance between aggressive material removal and surface integrity. For customers requiring specific cutting data or confirmation of compatibility, technical consultation is available to align tool choice with component geometry and machine capabilities.

FAQ

What machining tasks is this insert best suited to?
This insert is designed for high‑feed pocket and face milling; the DoFeed geometry and the AH130 grade make it suitable for applications requiring high material removal rates with stable cutting behaviour.

How does the AH130 grade affect tool life?
The AH130 grade is a PVD‑coated cemented carbide developed for wear and chipping resistance; the coating and substrate together improve edge retention and extend usable life in interrupted and continuous milling.

What clamping features ensure secure mounting of the insert?
The insert includes a cylindrical hole with a double‑sided countersink (40°–60°) that provides reliable seating in compatible DoFeed cutter bodies and helps maintain consistent runout and clamping force.

Can the insert be indexed and reused?
Yes, the rectangular, double‑sided design enables indexing to a fresh cutting edge, supporting economical tool usage and simpler inventory management.

Is cutting data provided for this insert?
Recommended cutting parameters depend on workpiece material and machine capability; consult Metav Werkzeuge for application‑specific cutting data and optimisation advice for the LNMU 0303ZE AH130 indexable insert.
