VNMG 160412 AH905 Turning insert by Tungaloy – PVD-coated carbide, rhombic ISO turning insert for general turning

A VNMG160412 AH905 rhombic ISO turning insert designed for external and internal turning, featuring a 1.2 mm corner radius, double-sided chipbreaker and a cylindrical central hole for secure clamping and repeatable performance.

• Rhombic VNMG geometry, ISO 160412
• AH905 PVD-coated carbide for wear resistance
• 1.2 mm corner radius for stable cutting
• Double-sided chipbreaker with central hole

Reliable wear resistance for high-process stability

The PVD-coated AH905 grade offers a balance of wear and fracture resistance that supports repeatable machining results. The carbide substrate provides fundamental toughness, while the PVD coating improves wear behaviour during dry or lubricated cutting. This combination reduces flank and crater wear rates, which in turn maintains dimensional accuracy over longer tool life and fewer insert changes. For process planners, this means predictable tool change intervals and improved machine utilisation.

Versatile geometry for a wide range of turning tasks

The rhombic VNMG form with a 35° lead angle enables efficient chip flow and adaptable cutting directions for both external and internal turning. The 1.2 mm corner radius stabilises the cutting edge in interrupted cuts and when machining variable cross-sections, improving surface finish and reducing vibration. The double-sided design offers economical indexability, and the central cylindrical hole ensures positive seating in compliant ISO-compatible holders, supporting secure clamping and consistent axial position.

Clear compatibility and straightforward mounting

Compatibility with holders is determined by form, relief angle, tolerance class, fastening type, size and thickness; the insert features a 0° relief angle and a plate thickness of 4.76 mm, matching standard ISO clamping systems. Select a matching external holder or boring bar that accepts ISO 160412 geometry and provides the correct clearance and clamping torque. For less experienced buyers, specifying the insert code together with the holder model number ensures correct pairing and avoids downtime due to incorrect mounting.

Productivity gains and economical operation

Using a PVD-coated, double-sided indexable insert reduces per-part tooling cost through multiple effective cutting edges and extended life under stable cutting conditions. The carbide base and AH905 coating support productive turning of a broad range of steels and cast irons when appropriate chipbreakers and cutting parameters are selected. Focusing on process stability and correct insert selection pays off in fewer tool changes, consistent part quality and improved overall process efficiency.
