VCMT 160412 AH8005 – ISO rhombic turning insert, PVD-coated carbide (Tungaloy)

A VCMT160412 AH8005 rhombic ISO turning insert for stable external and internal turning of heat-resistant alloys and hard materials

• PVD-coated carbide for wear resistance
• CM chipbreaker for controlled chip formation
• 1.2 mm corner radius for robust edges
• ISO rhombic VCMT160412 with central hole

Consistent performance with a heat-resistant carbide grade

The PVD-coated carbide grade AH8005 offers improved wear resistance at elevated cutting temperatures, making it suitable for machining heat-resistant alloys and other demanding materials. The coating reduces adhesive and abrasive wear during prolonged cuts, resulting in more predictable tool life and fewer interruptions to the machining cycle. For stable setups and steady cutting conditions the grade is optimised to balance toughness and hardness for productive turning operations.

Geometry that enhances stability and surface quality

The VCMT160412 rhombic shape combines a compact footprint with a 1.2 mm corner radius, which provides a robust cutting edge for interrupted cuts and heavier depths of cut. The CM chipbreaker promotes segmented, controllable chips that reduce the risk of entanglement and improve swarf evacuation, while the 7° clearance angle helps maintain a positive cutting geometry with reduced rubbing. The insert’s central hole and one-sided countersink (40°–60°) ensure secure clamping and simple orientation in compatible holders, supporting consistent surface finish and dimensional repeatability.

Systematic selection for reliable process integration

As part of an ISO insert system, the component works together with a matchingholder or boring bar, underlay/clamping set and replacement screws; compatibility depends on form, clearance, tolerance class, fastening method, size and thickness. The insert’s PVD-coated carbide body and chipformer combination support reproducible cutting results and reduced rework. For focused productivity gains, select the chipbreaker and grade to match the workpiece material and the machine’s rigidity; Metav Werkzeuge’s technical advisers are available to clarify suitability and recommend the correct holder and clamping items.

FAQ

Is this insert suitable for machining heat-resistant alloys? The Tungaloy VCMT160412 AH8005 insert is designed for heat-resistant alloys and hard materials; the PVD-coated AH8005 grade improves wear resistance under elevated temperatures.

Which chip behaviour can be expected with this chipbreaker? The CM chipbreaker on this insert produces segmented, controllable chips that aid swarf evacuation and reduce chip entanglement during turning.

What holders are compatible with this insert shape? Compatibility depends on the holder’s form, clearance angle, tolerance class, fastening method, size and thickness; the ISO rhombic form and central hole match standard ISO-compatible external holders and boring bars.

How does the 1.2 mm corner radius affect performance? A 1.2 mm corner radius provides a robust cutting edge that tolerates intermittent cuts and higher feed forces, improving edge life and minimising edge chipping.

Are countersunk holes suitable for secure clamping? The insert’s cylindrical hole with a one-sided countersink (40°–60°) ensures reliable clamping and repeatable orientation in appropriately designed clamping systems.
