LNMU 0303UE AH130 milling insert by Tungaloy — rectangular 03, 90° for milling systems

The LNMU 0303UE AH130 is a rectangular milling insert designed for Tungaloy milling systems, intended for plan, shoulder, slot, high-feed and contour milling when matched to the correct cutter body and seat.

• PVD-coated carbide grade AH130 for milling
• Double-sided chipbreaker for stable chips
• Rectangular 03 format, 90° cutting angle
• Cylindrical hole with double-sided countersink 40°–60°

Precision fit and system compatibility for reliable set-ups

The insert is manufactured for use in systems where seat, geometry and cutter body must be technically compatible; this ensures repeatable clamping and minimal run-out. The rectangular 03 format with a 90° cutting angle delivers predictable flank contact and rigid engagement in shoulder and face milling. By matching the insert geometry to the toolholder, setup times are reduced and stability in heavy cuts is increased, which translates into fewer reworks and higher throughput.

Wear resistance and process security through advanced coating

The PVD coating applied to the AH130 grade enhances wear and chipping resistance while maintaining a sharp cutting edge, making this insert suitable where edge integrity and process security are required. PVD (physical vapour deposition) creates a thin, hard layer that reduces abrasion and adhesion at the cutting interface; as a result, the insert sustains cutting performance for longer tool life and more consistent surface finish. This combination is especially beneficial under intermittent or unstable cutting conditions where chipping risk is elevated.

Design details that support productive milling operations

A 3.18 mm plate thickness and double-sided chipbreaker design assist in stable chip control and allow economical indexability. The insert includes a cylindrical hole with a double-sided countersink (40°–60°) to suit common clamping schemes and to ensure secure seating under torque. The nominal 0° clearance angle supports full-faced engagement where the tool family dictates, while the PVD-coated carbide substrate offers a balance between toughness and hardness. Together these features yield reliable cutting performance across a wide range of milling tasks without compromising process consistency.

FAQ

Which milling operations are suitable with this insert?
The LNMU 0303UE AH130 insert is suitable for plan, shoulder, slot, high-feed and contour milling when used in the corresponding Tungaloy cutter bodies and seat geometries.

How does the AH130 grade affect tool life?
The AH130 grade, with its PVD coating, increases wear and chipping resistance and helps maintain a sharp cutting edge, resulting in extended service life under many milling conditions.

Is the insert indexable on both sides?
Yes, the design is double-sided with a chipbreaker on both faces, allowing economical indexing and renewed cutting edges.

What clamping features must the cutter body provide?
The cutter body must match the insert seat and geometry; the LNMU 0303UE requires a compatible seat and a screw/clamping system that accepts a cylindrical hole with a double-sided countersink.

Can this insert be used for interrupted cuts?
The wear-resistant AH130 grade and robust chip control make the insert suitable for many interrupted cutting scenarios, offering improved process security versus non-coated grades.
