VBMT 160408 AH725 – ISO turning insert for external and internal turning by Tungaloy

The VBMT160408-PSS AH725 is an ISO-standard rhombic turning insert, PVD-coated and optimised for general-purpose machining of steel and stainless steel in applications demanding stable chip control and repeatable results.

• ISO-standard VBMT 160408 insert
• PVD-coated AH725 universal grade
• 0.8 mm corner radius for stability
• Cylindrical hole with countersink 40°–60°

Stable machining across mixed steel grades

The combination of the AH725 grade and a PVD-coated surface provides a robust, wear-resistant cutting edge suited for a wide range of steels and stainless steel alloys. This carbide grade is formulated for reliable, breakage-resistant performance, which reduces unexpected tool changeovers and supports continuous production. The result is improved process security and fewer interruptions during turning operations, particularly where workpiece materials vary.

Geometry tuned for consistent surface quality

A rhombic form with a 35° lead angle and a 0.8 mm corner radius offers a deliberate compromise between edge strength and surface finish. The modest corner radius helps absorb intermittent loads while still permitting a fine surface on external and internal profiles. In practice, this geometry minimises burr formation and maintains dimensional stability, especially when using smaller tooling setups or when tighter tolerances are required.

Effective chip control and secure clamping

Equipped with the PSS chipbreaker, the insert guides chips into short, manageable segments, reducing risk of entanglement and easing evacuation in confined setups. The insert’s cylindrical hole with single countersink (40°–60°) ensures positive location and repeatable clamping when paired with the appropriate holder, shim and clamp set. Compatibility depends on insert form, clearance angle, tolerance class, mounting arrangement, size and thickness; matching these to the holder achieves the intended clamping rigidity and cutting stability.

Practical integration and application guidance

The insert is supplied in the ISO VBMT format and forms part of a system that includes a suitable external holder or boring bar, a supporting shim or clamp kit and replacement screws. For external and internal turning applications, select the AH725 grade for mixed-material batches and where high process reliability is a priority. The construction and coating make this insert an economical choice for workshops seeking consistent tool life and reproducible results with a low risk of chipping.

FAQ

What materials is this insert suitable for?
The VBMT160408-PSS AH725 insert is formulated for machining steel and stainless steel, offering robust wear resistance and stable performance across mixed-material batches.

How does the PSS chipbreaker affect machining?
The PSS chipbreaker on the VBMT160408-PSS AH725 produces short, controllable chips that simplify evacuation and reduce the risk of chip re-cutting or entanglement in turning operations.

Which holders are compatible with this ISO insert?
Compatibility is defined by the insert form, clearance angle, tolerance class, mounting type, size and thickness; use the ISO VBMT holder types and ensure the clamp/shim matches the VBMT160408-PSS geometry.

What surface finish can be expected with a 0.8 mm corner radius?
A 0.8 mm corner radius provides improved edge robustness while still enabling a fine surface finish on external and internal profiles, making it a versatile choice for general-purpose turning.

Is the product delivered ready for mounting?
The insert designation VBMT160408-PSS AH725 represents the ISO-standard cutting plate; for a complete setup, combine it with an appropriate external holder or boring bar, supporting shim/clamp set and replacement screws.
