VCMT 160408 AH725 — ISO turning insert for external and internal turning by Tungaloy

The VCMT 160408 AH725 is an ISO-standard indexable turning insert designed for general-purpose turning; compatible holders should match form, clearance angle, tolerance class, clamping and thickness

• ISO turning insert VCMT160408-PSF
• PVD-coated carbide grade AH725
• PSF chipbreaker for secure chip control
• 0.8 mm corner radius, 7° clearance

Consistent process security with a universal turning grade

The combination of a PVD-coated carbide substrate and the AH725 grade delivers consistent performance across a wide range of materials, specifically Stahl and rostfreier Stahl. This creates a clear benefit for mixed production runs: fewer tool changes and stable cutting behaviour. The PVD layer increases wear resistance while preserving cutting-edge geometry, which translates into predictable tool life and reduced scrap rates. The grade is optimised for applications requiring high process security and is suitable for smaller tools or setups where reproducibility matters.

Controlled chips and improved surface finish

The dedicated PSF chipbreaker promotes short, manageable chips in typical turning operations, reducing the likelihood of entanglement and secondary finishing work. Combined with the rhombic insert form and an included cylindrical hole with one-sided countersink (40°–60°) for reliable clamping, the system supports a steady chip flow and consistent contact between insert and workpiece. The 0.8 mm corner radius helps produce a good surface quality while the 7° clearance minimises rubbing, offering a practical balance between strength and finish in both external and internal turning.

ISO compatibility for fast changes and lower setup risk

The insert follows ISO dimensions and tolerances, so compatibility is governed by form, free angle, tolerance class, clamping style, size and thickness. That allows a predictable fit into standard external holders or boring bars when the matching holder geometry is selected. The systematic setup — indexable insert, suitable external holder or boring bar, shim/clamping kit and spare screws — reduces mounting errors and shortens changeover time. Clear specification of these parameters supports process planners in avoiding mismatches and downtime.

Durable cutting edge with economical operation

Thanks to the PVD coating and the AH725 formulation, the insert provides enhanced edge stability and wear resistance under conventional turning conditions. The result is a longer effective tool life and a favourable cost-per-cut calculation when compared to uncoated grades. For users prioritising reliability, the rounded corner and robust chip control reduce sudden edge failures, helping to maintain throughput and consistent part quality across shifts.

FAQ

What materials is this insert suitable for?
The VCMT160408-PSF AH725 insert is specified for machining Stahl and rostfreier Stahl and is developed as a universal, break-resistant grade for mixed-material production.

Is the insert compatible with standard ISO holders?
Yes — the insert follows ISO dimensions (160408); compatibility depends on matching the holder’s form, free angle, tolerance class, clamping method, size and thickness.

Which chipformer is fitted and what benefit does it provide?
The insert uses the PSF chipbreaker, which promotes short, manageable chips and improves process security and surface quality in turning operations.

What are the key dimensional data to check before ordering holders?
Check the ISO code 160408, insert size 16 mm, thickness 4.76 mm, corner radius 0.8 mm and clearance angle 7° to ensure the correct holder choice.
