LNMU 0303ZE AH725 indexable insert for milling by Tungaloy — high-feed geometry, PVD-coated carbide

The LNMU0303ZE AH725 is a rectangular indexable insert designed for high-feed milling applications, optimised for pocketing and face milling with small axial depths and large time-chip volumes.

• High-feed geometry for large chip volumes
• Universal AH725 PVD-coated carbide
• Double-sided chipbreaker for stable cutting
• Cylindrical hole with countersink for secure clamping

Increase material removal rates with consistent chip control

The DoFeed series concept enables significantly higher material removal per unit time by using a specialised geometry that allows large radial engagement with minimal axial depth. The combination of low axial cuts and an optimised rake geometry reduces cutting forces while maintaining feed per tooth, delivering a clear throughput advantage for repetitive pocketing and face milling tasks. The double-sided chipbreaker keeps chips compact, which lowers the risk of chip re-cutting and protects the workpiece surface; in practice this means fewer interruptions and more predictable machining cycles.

Secure performance across steels and stainless steels

The insert is made from PVD-coated carbide in the AH725 grade, a universal, breakage-resistant composition tailored for mixed-material shops and smaller tool sizes. This grade provides a balanced wear resistance and toughness, making it suitable for both plain steel and stainless steels where process security is critical. The PVD layer improves edge stability and reduces flank wear, so the cutting edge retains form for longer under varying cutting conditions. For engineers seeking repeatable results, this translates into reduced downtime and more consistent surface finishes.

Practical system design for fast tool handling and repeatable clamping

The insert features a rectangular 03 form with a thickness of 3.18 mm and is supplied with a cylindrical hole plus a double-sided countersink (40°–60°) to ensure secure seating on compatible milling bodies. The 90° edge orientation and a 0° relief ensure predictable engagement and straightforward indexing; once mounted on a DoFeed-compatible cutter body with the appropriate screws, the insert can be rotated to a fresh edge quickly, minimising machine idle time. Practical workshop advantages include simplified inventory (one universal grade for multiple steels) and straightforward matching to existing holders within the DoFeed system.

FAQ

What machining tasks is this insert intended for?
The insert is designed for high-feed milling tasks such as pocketing and face milling; the DoFeed family and the AH725 grade make the insert particularly suitable for large time-chip volumes at low axial depths.

Can the insert handle stainless steels?
Yes, the AH725 PVD-coated carbide grade provides a balance of toughness and wear resistance that is suitable for machining steel and stainless steels with improved process security.

What clamping features ensure stable seating?
A cylindrical hole with a double-sided countersink (40°–60°) and a standard screw interface allow secure clamping on compatible DoFeed milling bodies, ensuring repeatable positioning and quick indexability.

How does the chipbreaker help production?
The double-sided chipbreaker maintains compact chips and reduces the risk of re-cutting, leading to more consistent surface quality and fewer interruptions during long production runs.

Is this insert compatible with a DoFeed cutter body?
Yes, the insert is part of the DoFeed series system and is intended for use with corresponding milling bodies, matching inserts and screws for efficient integration.
