LNMX160612 AH725 Tungaloy ISO turning insert — PVD‑coated carbide, 1.2 mm radius

A LNMX160612 AH725 ISO turning insert engineered for external and internal turning where stable chip formation and high process reliability are required.

• PVD‑coated carbide for process stability
• Universal AH725 grade for steel and stainless steel
• Robust 1.2 mm corner radius for edge strength
• ISO LNMX form for broad holder compatibility

Improved process security and longer tool life

The AH725 grade combines a PVD‑coated carbide substrate with a formulation tuned for both steel and stainless steel, delivering consistent cutting performance across mixed batches. The coating reduces adhesive wear and improves edge durability, which translates into fewer indexings and reduced machine downtime. For production environments with changing workpiece materials or smaller tool assemblies, the result is measurable: more consistent cycle times and a lower rate of unexpected tool changes. The focus on efficient chip control and fracture resistance supports a stable machining process and predictable component quality.

Precise fit, repeatable clamping and system compatibility

Designed to ISO LNMX form, this insert depends on matching the holder by form, relief angle, tolerance class, attachment, size and thickness. The 0° relief angle and a plate thickness of 6.35 mm ensure firm seating and repeatable geometry when combined with the correct clamp set and replacement screws. The rectangular 16 mm plate format and the special hole style require the appropriate holder or boring bar, but provide excellent rigidity once mounted. Clear definition of these parameters reduces setup time and enhances positional repeatability in serial production.

Practical selection guidance for optimum results

Choose the chipbreaker and grade to suit the material, operation and desired surface finish: the universal AH725 excels where process safety and resistance to chipping are priorities, especially in varying batches. A 1.2 mm corner radius favours strength and a robust cutting edge, suitable for general turning and semi‑finishing; if the requirement is a mirror finish or very fine tolerances, a smaller radius would be preferred. Because the insert belongs to an ISO system, integration into existing tool families is straightforward provided holder compatibility is checked; consider spare clamp components and screws as part of the toolset to maintain uptime.

FAQ

What materials is this insert suitable for?
The LNMX160612 AH725 Tungaloy indexable insert (SKU 6861557‑Tungaloy) is optimised for machining steel and stainless steel, offering robust chip control and resistance to edge breakage.

How does the AH725 grade help with mixed‑material batches?
The AH725 grade in this Tungaloy insert combines wear resistance and a fracture‑resistant microstructure so that the insert remains reliable when switching between different steels and stainless steels.

What should be checked for holder compatibility?
Compatibility depends on ISO LNMX form, relief angle (0°), tolerance class, attachment method, plate size (16 mm) and thickness (6.35 mm); ensure the holder or boring bar matches these parameters for repeatable clamping.

Is the 1.2 mm corner radius suitable for finishing?
A 1.2 mm corner radius provides a sturdy cutting edge for general turning and semi‑finishing; for finesse surface finishes, a smaller radius is typically recommended.

Does the insert require special clamping parts?
This LNMX insert uses a special hole style and may require a corresponding underlay/clamp set and replacement screws as part of the full system assembly.
