VNMG120404E-TSF AH6225 — ISO turning indexable insert for stainless steels, 0.4 mm corner radius (Tungaloy)

The VNMG120404E-TSF AH6225 is an ISO-standard rhombic turning insert engineered for external and internal turning operations on stainless steels, offering a balanced edge for medium machining conditions.

• PVD-coated carbide AH6225 for stainless steels
• Rhombic VNMG form, ISO 120404 size
• 0.4 mm corner radius for precise profiling
• Cylindrical hole for secure clamping

High process reliability through optimised grade and geometry

The combination of the AH6225 PVD-coated carbide and the rhombic VNMG geometry delivers predictable results in medium-duty turning of stainless steels. The coating supports a sharp, wear-resistant edge while the substrate ensures toughness under variable cutting forces. As a result, the insert provides stable tool life and consistent surface finish, reducing unplanned downtime and contributing to efficient batch production.

Straightforward integration with standard toolholders

Compatibility is governed by form, clearance angle, tolerance class, fastenings, size and thickness; the ISO 120404 designation and the VNMG outline simplify selection of a matching external holder or boring bar. The 0° clearance angle and the 35° approach orientation support a broad range of clamping systems, and the cylindrical hole ensures secure locating. Correct holder pairing helps maintain repeatable cutting conditions and repeatable component tolerances.

Effective chip control and material suitability

The TSF chipbreaker was developed for mixed stainless-steel applications and assists in splitting and evacuating chips during turning, especially under interrupted cuts. The PVD-coated surface reduces built-up edge tendency common with stainless alloys, while the carbide base provides the necessary edge stability. For customers processing ferritic, austenitic or duplex grades, this insert offers a reliable balance between surface quality and tool life.

Productivity advantages and recommended use cases

Designed for external and internal turning, this indexable insert supports medium cutting parameters where a sharp yet robust edge is required. The 0.4 mm corner radius allows accurate profile work and dimensional control on turned features. Selecting the appropriate chipbreaker and matching insert grade to the workpiece material results in fewer tool changes, improved cycle times and a steadier production flow for both small and large batches.

FAQ

What materials is this insert suitable for?
The VNMG120404E-TSF AH6225 insert is specified for stainless steels, providing a balanced cutting edge and wear resistance for common austenitic and ferritic grades.

How does the TSF chipbreaker affect machining?
The TSF chipbreaker on this indexable insert helps control and break chips during turning, improving chip evacuation and reducing the risk of entanglement in general stainless-steel machining.

Which holders are compatible with the ISO 120404 VNMG geometry?
Compatibility depends on holder form, tolerance class, fastening method and size; holders designed for VNMG ISO 120404 inserts with a matching clamping system are suitable for secure use of this insert.

Is the AH6225 grade suitable for interrupted cuts?
The AH6225 PVD-coated carbide substrate offers sufficient edge stability for many interrupted-cut scenarios in medium machining, though specific cutting parameters should be validated per application.

What is the significance of the 0° clearance angle and 35° approach?
A 0° clearance angle supports certain holder geometries and edge strength, while the 35° approach angle influences cutting forces and surface finish; together they guide holder selection and cutting-condition optimisation.
