VBMT 160404 AH725 ISO turning insert for turning, Tungaloy

The VBMT160404-PSS AH725 is an ISO‑standard rhombic turning insert designed for external and internal turning, featuring a 0.4 mm corner radius, a PSS chipbreaker and a cylindrical mounting hole with single‑side countersink.

• Universal PVD-coated AH725 grade
• ISO rhombic insert, 16 mm size
• 0.4 mm corner radius for fine finishes
• Cylindrical hole with 40°–60° countersink

Higher process security through a universal PVD grade

The primary advantage of the AH725 grade is its balance between wear resistance and fracture toughness. As a PVD‑coated carbide, this grade reduces flank and crater wear at common cutting speeds while maintaining cutting‑edge stability in interrupted cuts. The result is fewer index changes and a more predictable tool life, which supports continuous production and lowers the risk of unexpected downtime.

ISO compatibility for straightforward tool integration

The insert follows the ISO designation 160404, which simplifies selection and ensures mechanical fit with standard holders. The rhombic plate form and the 16 mm size match most ISO compatible external holders; compatibility is determined by geometry, clearance angle, tolerance class, fastening method, size and thickness. The PSS chipbreaker is optimised for mixed operations, making retrofitting into existing tool systems fast and reliable.

Consistent surface finish and chip control for productivity gains

A 0.4 mm corner radius delivers a fine surface finish without sacrificing edge strength on smaller tools. Combined with the engineered chipbreaker, chip flow is directed away from the workpiece and toolholder, reducing rework and manual handling. This targeted chip control contributes directly to improved productivity, shorter cycle times and safer machining conditions on batch runs.

Recommended applications and machining hints

Designed for turning tasks, the insert suits external and internal turning of Stahl and rostfreier Stahl, particularly where material mixes occur and process reliability is critical. The combination of the PVD coating and the fracture‑resistant substrate is well suited to smaller tools and operations requiring repeatable edge performance. For best results, select the holder and clamping set that match the insert’s form, free angle and tolerance to preserve clamping integrity and repeatability.

FAQ

Which materials are suitable for this insert?
The VBMT160404-PSS AH725 from Tungaloy is designed for machining Stahl and rostfreier Stahl and performs well where material types vary; the PVD coating and grade balance wear resistance and toughness.

What does the ISO code 160404 indicate?
The ISO code identifies the insert geometry and size; 160404 denotes a rhombic plate form with the specified nose radius and dimensions for standard holders.

How does the PSS chipbreaker affect machining?
The PSS chipbreaker organises chip flow for safer evacuation and improved surface quality, reducing the likelihood of built‑up edge and tool interference during turning.

Is this insert suitable for internal turning?
Yes, the geometry and chip control make the insert appropriate for internal as well as external turning operations, provided the holder matches the insert dimensions and mounting style.

How should clamping and holder selection be approached?
Choose a holder that matches the insert form, free angle, tolerance class, fastening method, size and thickness to ensure stable clamping and repeatable cutting performance.
