LNMX 160608 AH725 turning insert (ISO) – PVD-coated cemented carbide, 0.8 mm radius | Tungaloy

LNMX 160608 AH725 is an ISO-format indexable insert for external and internal turning, designed as a universal, fracture-resistant grade for steel and stainless steels.

• PVD-coated carbide AH725
• Universal for steel and stainless steels
• ISO LNMX160608 format
• 0° clearance, 90° included angle

Reliable cutting performance for everyday turning

The PVD-coated AH725 grade is formulated as a universal, crack-resistant solution that balances wear resistance and edge stability for a wide range of steels and rust-free steels. As a cemented carbide insert with a 0.8 mm corner radius, it delivers predictable tool life and consistent component quality in batch and single-piece production. The coating reduces built-up edge and extends interval times between index changes, which supports a steady production flow and lowers overall process cost.

Clear compatibility and simple system integration

Compatibility with holders is governed by geometric and mechanical parameters such as form, clearance angle, tolerance class, fixing method, size and thickness. The LNMX160608 format follows ISO conventions and fits appropriate LNMX-capable holders when the 6.35 mm plate thickness and 16 mm seat dimension are matched. Specifying the correct holder/profile and checking the special hole and mounting style avoids fitment issues and ensures stable clamping, which in turn improves repeatability and surface finish.

Choose the right chip control and enhance process security

The insert features a special chipbreaker designation suitable for turned components where chip form and evacuation are critical. Selecting the chipbreaker and grade to match material, cutting data and machine stability reduces the risk of interruptions and workpiece damage. For operations with varying materials or shorter tools, the universal AH725 grade provides robust performance and improved process security, especially under changing cutting conditions where a dependable edge is required.

Practical system concept and maintenance advantages

This ISO insert is part of a system comprising the indexable plate, compatible external holder or boring bar, seating shim or clamp kit and spare screws. Clear documentation of the system components and straightforward replacement of worn inserts keep machine downtime to a minimum. The combination of standardised geometry and a durable coating simplifies inventory management while maintaining the quality and repeatability necessary for precision turning tasks.

FAQ

Which materials are suitable for this insert?
The LNMX160608 AH725 insert is designed as a universal grade primarily for steel and rust-free steels, offering reliable performance across varying alloys.

What is the corner radius and why is it important?
This insert has a 0.8 mm corner radius, which helps balance edge strength and finish: a larger radius improves robustness while still allowing acceptable surface quality on turned parts.

Will this insert fit existing LNMX holders?
Compatibility depends on holder form, clearance angle, tolerance class, fixing method, plate size and thickness; the ISO-format LNMX160608 matches LNMX-capable holders when those parameters align.

How does the AH725 grade affect chip control?
The PVD-coated AH725 grade combines a fracture-resistant substrate with coating benefits to reduce built-up edge; matched with the appropriate chipbreaker, it delivers consistent chip form and evacuation for stable machining.

Is the insert suitable for internal and external turning?
Yes, the insert is applicable to both external and internal turning when used with the correct holder geometry and machining parameters.
