VCMT 160412 AH905 ISO turning insert — PVD‑coated carbide, 1.2 mm corner radius — Tungaloy

A VCMT160412 AH905 is an ISO‑standard rhombic indexable insert designed for precise external and internal turning where a sharp, durable cutting edge and process security are required.

• PVD-coated carbide AH905
• 1.2 mm corner radius
• Rhombic form, 35° cutting angle
• Cylindrical hole with 40°–60° countersink

Durable coating and grade for steady productivity

The combination of a PVD‑coating with a carbide substrate in the AH905 grade provides a balance between wear resistance and a consistently sharp edge. This leads to longer tool life under interrupted cuts and when handling tougher workpiece materials. The coating reduces adhesion and thermal load at the cutting zone, while the substrate retains edge stability — a pairing that supports predictable tool changes and less frequent regrinding. These technical characteristics translate directly into fewer production stops and improved process reliability when machining on a repeatable production schedule.

Predictable mounting and ISO compatibility for fast integration

Designed as part of an ISO‑standard turning insert family, compatibility is governed by the insert form, 7° relief, tolerance class, fastening type, size and thickness. The rhombic geometry with a 35° cutting angle and a 4.76 mm plate thickness ensures the insert fits standard holders that accept VCMT shape inserts. The centre hole is a cylindrical hole with a single‑side countersink (40°–60°), enabling secure clamping and straightforward replacement. These defined dimensions allow for repeatable seating and orientation in a holder, reducing set‑up times and helping to maintain consistent component geometry across batches.

Stable cutting action and recommendations for use

The chipbreaker CM delivers reliable chip formation across a range of materials when combined with the corner radius 1.2 mm, providing edge strength for moderate to heavy cuts and helping to avoid premature chipping. The rhombic form supports both external and internal turning tasks while the grade's fracture resistance is particularly suitable where a sharp cutting edge and process safety are both demanded. Select cutting parameters to match the grade and chipbreaker: climb or conventional turning can be applied depending on fixture rigidity and surface finish requirements. If further specification is needed for specific workpiece alloys or cycle optimisation, Metav Werkzeuge's technical advisors can provide machining data and recommendations.

FAQ

What materials is this insert best suited for?
The VCMT160412 AH905 insert is a wear‑resistant PVD‑coated carbide grade suited for a wide range of steels and general turning tasks where a sharp cutting edge and process security are required.

How does the chipbreaker affect performance?
The chipbreaker CM on the VCMT160412 AH905 promotes stable chip control and predictable breakage patterns, reducing the risk of chip entanglement and improving surface quality in continuous and interrupted cuts.

Which holder characteristics must be checked before installation?
Verify holder compatibility with the ISO VCMT form, the 7° relief, 16 mm seating, 4.76 mm thickness and the central hole style to ensure secure clamping and correct geometry in the assembly.

What advantages does the AH905 grade provide over uncoated inserts?
The AH905 PVD coating reduces adhesion and thermal stress at the cutting edge, extending life and maintaining finish quality compared with uncoated carbide in many turning operations.

Can this insert be used for internal turning as well as external?
Yes, the rhombic geometry and the 1.2 mm corner radius make it suitable for both external and internal turning applications where the insert geometry and holder allow the required approach angles.
