VCMT160404-PS AH725 ISO turning insert (VCMT 160404) by Tungaloy — PVD carbide for turning

VCMT160404-PS AH725 is a PVD-coated carbide ISO insert designed for robust external and internal turning, offering a universal, breakage-resistant grade suited to mixed production environments

• VCMT rhombic insert, ISO 160404
• PVD-coated carbide AH725 for steel and stainless
• Designed for external and internal turning
• Cylindrical hole with single-sided countersink

Reliable cutting for mixed-material production

The AH725 grade is a PVD-coated carbide developed as a universal, breakage-resistant option for machining steel and stainless steel. In practise, the combination of a wear-resistant coating and a tough substrate reduces unexpected edge failures and maintains cutting geometry over longer tool life. This reliability translates into fewer interruptions for tool changes and more predictable cycle times, which is particularly valuable in series production with varying workpiece materials.

Engineered geometry for secure clamping and predictable accuracy

As an ISO 160404 rhombic insert, the geometry and mounting features determine compatibility with the toolholder: form, relief angle, tolerance class, fastening and thickness must match the clamping system. Key dimensions include an inscribed size of 16 mm, corner radius 0.4 mm, relief angle 7°, and a plate thickness of 4.76 mm; the insert is supplied with a cylindrical hole and a single-sided countersink (40°–60°) to suit standard clamping screws. These defined parameters ensure repeatable seating and stable cutting conditions, reducing vibration and improving dimensional consistency on turned components.

Built for process security and small-tool productivity

The chipbreaker type PS paired with the AH725 grade is suited to smaller tools and operations where process security is critical. The insert’s design supports reliable chip control and surface finish while reducing the risk of catastrophic edge breakout during interrupted cuts. In short runs or mixed-batch production, fewer tool failures and steady wear characteristics contribute to lower overall machining costs and higher throughput. The insert is compatible with standard holder systems as part of an ISO turning insert setup, enabling straightforward integration into existing tooling stocks.
