VBMT110304 AH725 — ISO turning insert for external and internal turning — Tungaloy

The VBMT110304-PSS AH725 is an ISO-standard rhombic turning insert designed for robust external and internal turning where process security and versatile material coverage are required.

• PVD-coated carbide grade AH725
• Universal, chip-break resistant grade
• ISO-standard rhombic insert (110304)
• 0.4 mm corner radius for fine finishing
• Cylindrical hole with 40°–60° countersink

Reliable grade and coating for mixed-material production

The combination of the AH725 grade and a PVD-coated carbide substrate delivers a balance of wear resistance and fracture toughness, designed for stable machining of steels and stainless steels. As a universal, chip-break resistant grade, this insert is particularly suited to production environments with varying workpiece materials or smaller tool geometries where consistent tool life and reduced breakouts are priorities. Compatibility with the cutting tool holder is governed by form, relief angle, tolerance class, clamping method, size and thickness, all of which ensure repeatable seating and predictable performance under cycle loads.

Geometry tuned for surface quality and repeatability

The rhombic plate shape together with a 0.4 mm corner radius and a 35° lead angle supports a fine surface finish while maintaining adequate edge strength for typical turning cuts. The insert's relief angle of 5° and plate thickness of 3.18 mm contribute to stable cutting behaviour and minimise chatter in modest overhang configurations. The integral PSS chipbreaker is engineered to control chip form across a range of feeds and depths, helping to avoid entanglement and to keep downstream processes running smoothly. The cylindrical hole with a single-sided countersink (40°–60°) offers secure clamping and accurate repeatability when mounted in compatible ISO-style holders.

Application guidance and selection for dependable results

Placed within the ISO turning insert system, this cutting grade performs best for both external and internal turning operations where process security is a primary requirement. For higher demands on edge life or when machining harder alloys, selection of the correct chipbreaker and an appropriate grade becomes decisive; the AH725 grade is a pragmatic choice when frequent material changes occur. For tailored advice on holder compatibility, recommended feeds and cutting speeds, or to confirm the suitability of the VBMT110304-PSS AH725 for a specific component, Metav Werkzeuge can provide technical consultation and swift supply options. The emphasis remains on maintaining stable cutting conditions and consistent part quality throughout the production run.

FAQ

Which workpiece materials are suitable for this insert?
The VBMT110304-PSS AH725 is specified for machining steel and stainless steels; the AH725 grade provides a universal, chip-break resistant solution suited to mixed-material production.

Is this insert suitable for both external and internal turning?
Yes — the ISO rhombic form and the PSS chipbreaker make this insert appropriate for external and internal turning applications within the ISO turning insert system.

How does the 0.4 mm corner radius affect the result?
A 0.4 mm corner radius gives a good balance between surface finish and edge strength; it supports fine finishing passes while maintaining sufficient robustness for standard turning cuts.

What ensures repeatable clamping of the insert?
Repeatability is supported by the cylindrical hole with a single-sided countersink (40°–60°) and adherence to ISO form, size and thickness standards when mounted with a matching holder and clamping set.

For which cutting conditions is the PSS chipbreaker optimised?
The PSS chipbreaker controls chip form effectively across varying feeds and depths, improving chip evacuation and enhancing process stability when machining steels and stainless steels with this Tungaloy insert.
