VCMT 160402 AH6225 turning insert (VCMT160402-TSF) — Tungaloy

VCMT160402-TSF AH6225 is an ISO-standard turning insert engineered for external and internal turning where a sharp, stable cutting edge is required, particularly in rostfreier Stahl applications.

• ISO-compliant rhombic geometry
• PVD-coated carbide AH6225 grade
• Designed for rostfreier Stahl machining
• 0.2 mm corner radius for precision

Consistent cutting performance under variable conditions

The insert is manufactured from carbide with a PVD-coated surface and the AH6225 grade, delivering a balance of sharpness and edge stability for medium machining. This combination reduces flank wear during interrupted cuts and supports repeatable cycle times in production. The TSF chipbreaker is optimised for controlled chip formation when machining rostfreier Stahl, improving process reliability and reducing the need for secondary edge dressing. As a result, machining windows are wider and tool-change frequency is reduced, which benefits throughput in batch production.

Seamless integration into ISO tool systems

Designed to the ISO dimensions of the VCMT family, the insert fits standard holders by matching form, clearance angle and tolerance class. The rhombic shape and 35° cutting geometry allow flexible use for both external and internal turning operations, while the cylindrical hole with single-side countersink (40°–60°) secures the insert reliably in the clamp. The plate thickness of 4.76 mm and size 16 mm ensure mechanical stability in heavier cuts. These standardised interfaces simplify tooling decisions and allow existing toolholders to be reused without requalifying the machine setup.

Improved process security and cost efficiency

With a sharp yet robust cutting edge, the insert offers predictable wear behaviour and good surface finish in variable conditions. The TSF chipbreaker supports short, curled chips to prevent entanglement and to maintain coolant access, which leads to fewer interruptions and lower scrap rates. The grade and coating combination aims for extended life in applications with moderate cutting parameters, which translates into lower total tool costs per component and a steadier production flow in small to medium series.

Practical selection and handling advice

For turning rostfreier Stahl with this insert, select cutting data that favour moderate speeds and stable feed to preserve the edge integrity of the PVD-coated carbide. The 0.2 mm corner radius offers a compromise between finish and edge strength; use a larger radius only if the holder and workpiece rigidity allow it. Where compatibility is uncertain, check holder form, free clearance angle (7°) and fastening method against the ISO designation VCMT160402-TSF before ordering. Proper clamping and correct countersink engagement are essential to prevent movement under load and to achieve repeatable component accuracy.

FAQ

What materials is this insert suitable for? The VCMT160402-TSF AH6225 insert is intended primarily for rostfreier Stahl machining; its PVD-coated carbide and TSF chipbreaker favour medium turning operations.

Which holders are compatible with this insert? Compatibility depends on ISO geometry: match holder form, free clearance angle (7°), tolerance class and clamp type to the VCMT160402-TSF designation for correct fit.

What does the TSF chipbreaker provide in practice? The TSF chipbreaker on this insert shapes short, manageable chips to improve chip evacuation and maintain coolant access during rostfreier Stahl turning.

Can the 0.2 mm corner radius be used for finishing passes? Yes, the 0.2 mm corner radius balances surface finish and edge strength; it is suitable for light finishing if machine and workpiece rigidity are adequate.
