VBMT160408-PS AH6225 — ISO turning indexable insert, PVD-coated carbide (Tungaloy)

A VBMT160408-PS AH6225 ISO turning insert designed for reliable external and internal turning of stainless steels in medium-duty and variable machining conditions.

• PVD-coated AH6225 grade
• 0.8 mm corner radius
• Cylindrical hole with 40°–60° countersink
• 4.76 mm plate thickness

Consistent performance where material variability occurs

The combination of a PVD-coated surface and the AH6225 carbide grade delivers a predictable cutting behaviour across a wide range of stainless steels. The PVD coating reduces built-up edge and improves surface finish, while the substrate maintains edge stability under intermittent cuts. This balance of coating and substrate ensures fewer tool changes and steadier cycle times, making the insert a practical choice for workshops seeking reliable productivity without overcomplicating process parameters.

Geometry engineered for repeatable results and edge security

The rhombic VBMT form with a 0.8 mm corner radius and 5° clearance angle provides a secure cutting geometry for general turning and light profiling. The included 35° configuration and the PS chipbreaker guide chip flow to prevent entanglement and support continuous cutting. Explained simply: the modest corner radius reduces peak cutting loads while the chip control features lower the risk of vibration, which results in improved surface quality and consistent dimensional outcomes on parts.

System compatibility and straightforward integration

As an ISO-standardised indexable insert, compatibility with holders is determined by form, clearance, tolerance class, fastening method, size and thickness. The insert’s 4.76 mm thickness and 16 mm size suit a broad range of external holders and boring bars; the cylindrical hole with single-sided countersink enables secure clamping and repeatable indexing. This means easier inventory management: one ISO designation matches multiple clamping systems, reducing the need for bespoke tooling.

Productivity, tool life and practical application advice

Designed for medium cutting conditions, the insert enables efficient turning with an emphasis on stable chip formation and extended tool life. The AH6225 grade is tuned to provide a sharp yet robust cutting edge, useful when workpieces vary between free-machining and tougher stainless alloys. For best results, pair the insert with a rigid setup, appropriate coolant strategy and holder with correct lead angle; modest feeds and controlled depth of cut will maximise the balance between surface quality and wear resistance.

FAQ

What materials is this insert suitable for?
The VBMT160408-PS AH6225 is formulated primarily for stainless steels; the AH6225 grade and PVD coating help control built-up edge and maintain performance across varied stainless alloys.

Which holders fit the ISO VBMT geometry?
Any holder or boring bar designed for the VBMT form and matching size, thickness and clamping style will be compatible; the insert’s standard ISO dimensions allow straightforward integration.

What does the PS chipbreaker do in practice?
The PS chipbreaker promotes controlled chip segmentation and safe evacuation during turning, which supports steady cutting and reduces risk of chip interference.
