LNMX 0405R4 AH120 LNMX – Milling indexable insert, PVD-coated carbide, rectangular 90° (Tungaloy)

The LNMX0405R4 AH120 is a rectangular indexable insert for milling applications within Tungaloy milling systems, engineered for a sharp cutting edge and reliable seating in compatible tool bodies.

• PVD-coated AH120 carbide for high wear resistance
• Rectangular insert with 90° geometry for milling
• Special hole and chipbreaker for secure clamping
• 5.56 mm plate thickness for stable cutting forces

Longer, more consistent edge life for productive milling

The PVD-coated AH120 grade is a cemented carbide that combines wear resistance with resistance to edge chipping, delivering longer tool life in interrupted and continuous milling. A PVD coating forms a hard, thin film that lowers flank wear and thermal stress at the cutting edge, which results in more consistent component quality and fewer indexings. This performance advantage reduces unexpected tool changes, supporting stable cycle times and predictable production planning.

Secure clamping and geometry for vibration control

The rectangular form with a 90° major cutting angle and a 0° free angle is designed to deliver robust engagement in milling operations. The insert’s special hole and integrated chipbreaker ensure a positive fit and controlled chip formation when assembled with the correct clamping screw and insert seat; this reduces micro-movement under load and helps maintain dimensional accuracy. Ensuring that plate seat, geometry and milling body are technically compatible avoids loosening, improves surface finish and contributes to reproducible machining results.

Broad milling use and practical assembly guidance

Intended for a range of milling tasks — from face and shoulder to slot, high-feed and contour milling (depending on the associated tool family) — the insert is particularly suitable where a sharp cutting edge and high process security are required. When specifying the insert, verify the mating milling cutter body, clamping screw and any underlay are matched to the LNMX0405R4 geometry to guarantee correct seating. The built-in chip control supports efficient evacuation of swarf, reducing recutting and tool stress in many typical industrial milling setups.

FAQ

Is the LNMX0405R4 AH120 compatible with all Tungaloy milling bodies?
Compatibility requires that plate seat, geometry and milling body are technically matched; the LNMX0405R4 AH120 insert must be mounted in a Tungaloy milling body designed for the LNMX form and 0405R4 ISO geometry.

What does the AH120 grade signify?
The AH120 designation identifies a PVD-coated cemented carbide grade optimised for wear resistance and resistance to edge chipping, offering a sharp cutting edge together with good process reliability for milling.

Which milling operations are suitable for this insert?
Typical applications are face milling, shoulder milling, slotting, high-feed and contour milling, depending on the assigned tool family and cutter body.

How should the insert be secured in the cutter?
Use the specified clamping screw and any recommended underlay; the LNMX0405R4’s special hole and chipbreaker are designed to ensure secure clamping and controlled chip flow when assembled correctly.

Can the LNMX0405R4 be used for high-feed milling?
Yes — the combination of a sharp cutting edge and the wear-resistant AH120 grade makes it suitable for high-feed milling scenarios when paired with an appropriate milling body.
