LNMU 0303UE AH8015 PVD-coated carbide milling insert with cylindrical hole – Tungaloy

LNMU 0303UE AH8015 is a rectangular milling insert designed for general-purpose and high-feed milling within Tungaloy milling systems, requiring matching insert seat and geometry for optimal performance

• PVD-coated carbide AH8015 for heat-resistant alloys
• Rectangular 03 format, 3.18 mm thickness
• Cylindrical hole with double countersink 40°–60°
• Double-sided chipbreaker for reliable chip control

Greater process reliability for heat-resistant alloys

The combination of a PVD-coated surface and the AH8015 cemented carbide grade provides an effective balance between wear resistance and edge stability, making the insert particularly suitable for demanding, heat-resistant alloys. The coating process creates a thin, hard layer that reduces adhesion and thermal degradation at the cutting edge; this translates into longer tool life and fewer changes during production, supporting higher uptime and lower per-part machining costs while maintaining consistent dimensional accuracy.

Secure clamping and compatibility reduce vibration

A secure interface is essential for repeatable milling results. The insert features a cylindrical hole with a double countersink (40°–60°) and a 90° seating geometry to ensure firm clamping in compatible cutter bodies. Correctly matched seat geometry and clamping torque limit micro-movement under load, which reduces chatter and enhances surface finish. This mechanical stability is particularly beneficial when switching between planing and contour operations where rigidity directly affects finish quality.

Controlled chips and versatile machining modes

The double-sided chipbreaker is engineered to produce short, controllable chips across a range of feeds and depths, simplifying chip evacuation and reducing heat at the cutting edge. The rectangular 03 format with 3.18 mm thickness supplies the necessary edge strength for planing, shoulder, grooving, high-feed and contour milling applications without sacrificing accessibility in compact cutter heads. Clear chip control decreases the risk of recutting and machine downtime, improving overall cycle efficiency.

Select the right insert for your milling system

The insert is part of a modular system build comprising the milling body, indexable insert, clamp screw and, where required, a backing plate; therefore, the insert seat and geometry must match the cutter body to guarantee performance. The LNMU 0303UE grade is optimised for general machining of heat-resistant alloys and is offered as a PVD-coated carbide solution for shops seeking a balance of productivity and reliability. For machine-specific parameters and cutting data, refer to the cutter manufacturer's recommendations or seek technical guidance to ensure the correct combination of body, insert and cutting conditions.

FAQ

What materials is this insert best suited for?
The LNMU 0303UE AH8015 insert is primarily specified for machining heat-resistant alloys; the PVD-coated AH8015 grade balances wear resistance and edge stability for such materials.

Does the insert fit all Tungaloy milling bodies?
Compatibility depends on matching the insert seat and geometry; the insert requires a corresponding seat that accommodates a cylindrical hole and the specified 90° seating to ensure correct clamping.

How does the chipbreaker benefit machining?
The double-sided chipbreaker produces short, controllable chips across a range of feeds, improving chip evacuation and reducing the chance of re-cutting and tool-build-up.

What are the key dimensional features to check before ordering?
Confirm plate thickness (3.18 mm), plate format (03), main angle (90°) and the presence of a cylindrical hole with double countersink to ensure the insert matches the cutter body.

Is this insert reversible or single-use per edge?
The rectangular format with double-sided chipbreaker allows for indexing of multiple cutting edges where applicable; inspection of the insert geometry will determine the number of usable edges.
