VCMT 160404 AH725 — ISO turning indexable insert (PVD‑coated carbide, Tungaloy)

A VCMT160404-PSF AH725 indexable insert designed for external and internal turning applications, combining a rhombic geometry with a 35° approach angle for versatile metalcutting tasks.

• PVD-coated AH725 carbide grade
• PSF chipbreaker for controlled chip formation
• ISO‑standard rhombic insert shape
• 7° clearance angle for stable cutting
• Cylindrical hole with single‑side countersink

Reliable performance and predictable tool life

The PVD‑coated AH725 grade delivers a balance of toughness and wear resistance that is optimised for a wide range of steels and stainless steels. The PSF chipbreaker promotes short, controllable chips under varied cutting conditions, reducing interruptions and tool‑related scrap. Thanks to the ISO standard geometry and the rhombic form factor, insert fitment and repeatability are straightforward; the combination of a 35° approach angle and a 0.4 mm corner radius supports stable chip flow and predictable surface finish. This section explains how material properties translate into higher uptime and fewer tool changes.

Compatibility and straightforward system integration

Integration into existing tool systems is determined by insert form, clearance angle, tolerance class, fastening and exact dimensions. The insert is supplied with a cylindrical hole plus a single‑side countersink (40°–60°) to match common mounting screws and clamping systems. The plate thickness of 4.76 mm and a nominal size of 16 mm make the component compatible with standard external holders and boring bars. For workshop planning, the system requires an ISO insert, a matching external holder or boring bar, a shim/clamping set and spare screws; this modular approach simplifies stock keeping while ensuring rapid replacement and minimal setup time.

Material grade and process security explained

The AH725 designation denotes a PVD‑coated carbide engineered for universal use with a focus on breakage resistance and consistent performance when machining steels and stainless steels. PVD coating enhances resistance to abrasion and built‑up edge, thereby extending tool life in interrupted cuts and mixed‑material batches. Selecting a universal, tough grade reduces the need for multiple specialised inserts across small batch runs or changing components, offering an economical route to maintain high process security without compromising surface quality.

Practical benefits for production workflows

Using an ISO‑conforming, PVD‑coated insert with a dedicated chipformer yields measurable workflow advantages: fewer tool changes, improved repeatability of dimensions and reduced cycle interruptions from poor chip control. The VCMT160404‑PSF AH725 insert is particularly suitable where operators require a robust compromise between wear resistance and resistance to chipping — for example, in component turning with varying part geometries or mixed steel grades. Clear specifications (35°, 7° clearance, 4.76 mm thickness) allow reliable programming of cutting data and predictable tool life calculations.

FAQ

What materials is this insert suitable for?

The VCMT160404‑PSF AH725 insert is designed for machining steels and stainless steels, benefitting from the AH725 PVD‑coated carbide for balanced wear resistance and toughness.

How does the PSF chipbreaker affect machining?

The PSF chipbreaker on the VCMT160404‑PSF AH725 produces short, controlled chips that reduce machine downtime and improve safety during turning operations.

Can this insert be used in existing ISO holders?

Yes; the insert follows ISO geometry and the cylindrical hole with single‑side countersink matches common clamping systems, allowing integration with compatible external holders and boring bars.

What advantages does the PVD coating provide?

PVD coating on the AH725 grade increases resistance to abrasive wear and helps prevent built‑up edge, which improves surface finish consistency and prolongs effective tool life.

Which spare components are typically required for a complete system?

A complete turning system for this insert comprises the ISO insert, a matching external holder or boring bar, a shim/clamping set and replacement screws to ensure secure mounting and fast changeovers.
