LNMX160612 AH725 ISO indexable turning insert — 90° rectangular, PVD-coated | Tungaloy

The LNMX160612 AH725 is an ISO-standard indexable insert engineered for external and internal turning, offering a universal grade for steels and stainless steels with high process security.

• ISO-standard rectangular insert
• PVD-coated carbide AH725 grade
• Universal for steel and stainless steels
• 90° geometry for stable cutting
• Corner radius 1.2 mm for robustness

Consistent performance across mixed steels and stainless steels

The universal AH725 grade combines a PVD-coated surface with a tough carbide substrate to provide reliable cutting in both steel and stainless steels. This combination reduces the risk of edge failure in varied workpiece batches and supports longer tool cycles, meaning fewer interruptions and a more consistent production rhythm. The 1.2 mm corner radius increases edge strength, while the insert’s geometry helps maintain a repeatable cutting force, improving dimensional stability on turned components.

Simple integration with ISO tooling systems

As an ISO-standard component, the insert fits into established tooling systems when the form, clearance angle 0°, tolerance class, clamping arrangement and dimensions are matched to the holder. The overall system typically comprises the insert, a compatible external holder or boring bar, a clamping set (shim) and replacement screws. Specifying the correct holder and clamping components eliminates assembly play, ensures secure fixation and preserves the coated cutting edge during high-feed or interrupted cuts.

Productivity advantages through predictable behaviour

The PVD coating delivers increased wear resistance and heat protection under continuous cutting, which supports higher cutting speeds where appropriate. Selecting a matching chipbreaker and grade for the workpiece and machining stability reduces built-up edge and improves surface finish, thereby raising overall productivity. For small tools and operations with varying materials, a universal insert grade like this minimises tooling variants in stock while maintaining the necessary process security for shop-floor reliability.

FAQ

What materials is this insert designed for?
The LNMX160612 AH725 insert is designed as a universal, break-resistant grade primarily for steel and stainless steels, making it suitable for workshops that handle mixed batches.

How is compatibility with a holder determined?
Compatibility depends on insert form, clearance angle (0°), tolerance class, clamping method, size and thickness; the LNMX160612 must be matched to a holder that accepts its rectangular shape and 6.35 mm thickness.

Which chipbreaker should be chosen for best results?
Select a chipbreaker matched to the workpiece and machining stability: the LNMX160612 AH725 performs well with a chipbreaker suited for mixed steels to ensure controlled chips and good surface finish.

What benefit does the PVD coating deliver?
The PVD coating on the AH725 grade increases wear resistance and thermal protection, helping to maintain edge integrity and supporting higher cutting speeds where process conditions allow.
