VBMT110308-PS AH725 — ISO turning insert, 0.8 mm radius, PVD-coated carbide (Tungaloy)

VBMT110308-PS AH725 is an ISO‑standard rhombic turning insert intended for external and internal turning of steel and stainless steels, designed to provide consistent chip formation and process security in mixed‑material production.

• PVD-coated AH725 for universal machining
• ISO rhombic insert, 11 mm size
• 0.8 mm corner radius for versatile finishes
• Cylindrical hole with single‑side countersink

Stable cutting results for mixed‑material production

The insert offers PVD-coated carbide in the AH725 grade, engineered for broad applicability across steel and stainless steels. The combination of coating and substrate increases resistance to built‑up edge and flank wear, which translates into longer tool life and fewer indexings in series production. The rhombic geometry with a 35° approach angle and a 0.8 mm corner radius enables a balance between strength and finish quality, while the PS chipbreaker assists in forming controllable chips under varying cutting conditions.

Precise fit and simple integration into ISO systems

Compatibility is determined by form, clearance, tolerance class, mounting and thickness; the insert conforms to ISO sizing, making retrofitting into existing holders straightforward. The insert’s 11 mm size and 3.18 mm thickness match standard clamping systems, and the central hole with a single‑side countersink (40°–60°) ensures secure seating and repeatable axial position. These factors reduce set‑up time and help maintain concentricity during external and internal turning operations, supporting process reliability in workshop and production environments.

Optimised chip control and process security

The PS chipbreaker and the 5° clearance angle work together to promote predictable chip flow and minimise vibration when machining medium to high strength steels. The result is a consistent surface finish and fewer unexpected interruptions. For smaller tools or applications where process security is paramount, the AH725 grade is a universal, fracture‑resistant choice that performs well under changing workpiece materials and variable machine dynamics, making it suitable for shops handling diverse turning tasks.

FAQ

What materials is this insert suitable for?
The VBMT110308-PS AH725 insert is designed primarily for steel and stainless steels, offering universal performance and fracture resistance across mixed‑material turning tasks.

How does the AH725 grade affect tool life?
The AH725 grade features a PVD coating and a robust carbide substrate that together improve wear resistance and reduce built‑up edge, resulting in extended tool life and fewer indexings in continuous operations.

Is the insert compatible with standard ISO holders?
Yes. The insert follows ISO dimensions (110308) and its 11 mm size, 3.18 mm thickness and central hole with countersink enable secure mounting in compatible ISO turning holders.

What surface finish can be expected with a 0.8 mm radius?
A 0.8 mm corner radius provides a good compromise between edge strength and finish quality; it supports improved surface finish over larger radii while maintaining sufficient toughness for interrupted cuts and mixed materials.

Can this insert be used for internal turning as well as external turning?
The geometry and mounting features of the VBMT110308-PS AH725 allow use in both external and internal turning applications, provided a suitable holder or boring bar is selected for internal setups.
