VBMT160404-PS AH725 — VBMT 160404 AH725 ISO turning insert, PVD-coated carbide (Tungaloy)

A VBMT160404-PS AH725 insert designed for ISO-compliant turning, offering universal performance and enhanced process security for steel and stainless-steel machining.

• ISO rhombic insert VBMT160404-PS AH725 (35°)
• PVD-coated carbide, universal grade AH725
• 0.4 mm corner radius for fine profiling
• Cylindrical hole with 40°–60° countersink

Consistent results through a universal cutting grade

The AH725 grade is a PVD-coated carbide developed for universality and resistance to chipping, making it particularly suitable where material types vary during a production run. With this cutting grade, the insert maintains edge stability in both mild and alloyed steel as well as stainless steels, reducing downtime caused by insert breakage. The PS chipbreaker is matched to the grade to promote controlled chip formation under a range of cutting parameters, which improves process reliability and lowers the frequency of tool changes—an advantage for batch production and mixed-material programmes.

Geometry that supports precision and surface quality

A rhombic geometry with a 35° lead angle and a 0.4 mm corner radius balances fine profiling and mechanical strength. The 5° clearance angle combined with a plate thickness of 4.76 mm contributes to stable clamping and predictable tool behaviour, which helps achieve repeatable component dimensions and improved surface finish. For parts requiring delicate edge definition or tight tolerances, the smaller corner radius reduces ploughing forces and minimises burr formation while still providing enough edge support for moderate depths of cut.

Practical system compatibility for workshop integration

The insert is delivered in an ISO format so compatibility with external holders is determined by form, clearance, tolerance class, fixation, size and thickness. The cylindrical hole with single-sided countersink (40°–60°) ensures secure clamping in common clamping systems, and the ISO standardisation simplifies inventory and holder selection across multiple machines. When integrating into an existing tool system, match the VBMT160404-PS geometry and thickness to the selected external holder and use the appropriate shim/clamp set and replacement screws to guarantee correct seating and repeatability.

FAQ

What materials is this insert suitable for?
The VBMT160404-PS AH725 is intended as a universal solution for machining steel and stainless steels, offering stable chip control and reduced risk of edge failure across a range of alloys.

What does the AH725 designation indicate?
AH725 denotes a PVD-coated carbide grade optimised for universality and resistance to chipping, combining good wear behaviour with reliable process security in turning applications.

Is the insert compatible with standard ISO holders?
Yes. The insert follows ISO dimensions; compatibility with a holder depends on form, clearance angle, tolerance class, fixation, size and thickness — ensure the holder matches the VBMT160404-PS geometry.

How does the 0.4 mm corner radius affect machining?
A 0.4 mm radius yields finer profile definition and lower cutting forces than larger radii, improving surface finish and reducing burrs while retaining sufficient edge strength for many turning tasks.

What fastening and hole style does the insert use?
The insert features a cylindrical hole and a single-sided countersink (40°–60°), designed for secure clamping in common clamp systems and straightforward replacement during tool changes.
