LNMU 0303ZE AH725 rectangular indexable insert for milling — Tungaloy DoFeed high‑feed family

LNMU0303ZE AH725 is a rectangular indexable insert designed for high‑feed milling, pocketing and face machining within the DoFeed series.

• DoFeed high‑feed milling family
• PVD‑coated AH725 universal carbide
• Double‑sided chipbreaker for secure cutting
• Cylindrical hole with countersink 40°–60°

Increase material removal while keeping axial cuts shallow

The DoFeed concept focuses on delivering large material removal rates with small axial engagements; this allows shorter cycle times without increasing radial load. The AH725 PVD‑coated carbide grade provides a universal, fracture‑resistant cutting edge suitable for Stahl and rostfreier Stahl, which is advantageous when batches contain mixed materials. By combining a high‑feed geometry with a robust grade, the insert supports efficient pocket and face milling, reducing the need for multiple tool types and enabling a predictable process output.

Stable chip control for consistent surface quality

A double‑sided chipbreaker and the rectangular 03 format are engineered to manage chip formation under high‑feed conditions, lowering the risk of built‑up edge and unexpected interruptions. The insert’s cylindrical hole with a double‑sided countersink (40°–60°) improves clamping stability and alignment in compatible tool holders, while the 90° cutting angle contributes to straightforward seat design and predictable engagement. These features translate into reduced vibration, improved surface finish and longer uninterrupted production runs.

Simple integration and dependable repeatability

The indexable geometry follows the ISO designation 0303ZE, with a plate thickness of 3.18 mm and a relief angle of 0°, allowing easy replacement in many standard milling bodies that accept the LNMU format. Using a single insert family across several operations reduces tool inventory complexity and supports faster setup. Traceability is aided by the manufacturer SKU and article identifiers, enabling reliable reorder and inventory control for continuous production.

FAQ

What is the main application of this insert?
The insert is intended for high‑feed milling operations; the DoFeed design suits pocket and face machining where large material removal per time is required with small axial depths.

Which materials can this grade handle?
The AH725 grade is formulated for universal performance on Stahl and rostfreier Stahl, offering good fracture resistance when workpieces include mixed steels.

What are the key dimensional identifiers to check before ordering?
Refer to ISO 0303ZE, plate size 03, thickness 3.18 mm, and the article number 6864162 to ensure compatibility with the chosen milling body.

How does the hole design support clamping and stability?
The cylindrical hole with a double‑sided countersink (40°–60°) provides secure seating and improved centring in compatible tool holders, which enhances stability during high‑feed cuts.

Is the insert suitable for operations requiring high process security?
Yes; the combination of AH725 PVD coating, robust cutter geometry and double‑sided chip control supports reliable, repeatable machining under demanding conditions.
