CNMG 160612 AH905 Turning insert — PVD-coated carbide, 80° rhombic — Tungaloy

The CNMG160612 AH905 indexable insert is an ISO-standard rhombic turning insert designed for external and internal turning, offering a sharp cutting edge and high process security.

• Rhombic 80° insert geometry
• PVD-coated carbide AH905 grade
• Double-sided chipbreaker for stability
• Cylindrical hole, ISO holder compatible

Greater process security with a sharp, wear-resistant cutting edge

The CNMG160612 AH905 combines a PVD-coated carbide substrate with a grade developed for wear and chipping resistance, ensuring a consistently sharp cutting edge under stable cutting conditions. The PVD coating reduces adhesive wear and improves edge integrity, which translates into fewer unplanned tool changes and more predictable component tolerances. For operations that require repeatable quality—such as batch turning of critical diameters—the enhanced edge life contributes directly to reduced cycle variability and improved first-pass yield.

Smooth integration into ISO turning systems for efficient set-up

Designed to the ISO turning plate format, this rhombic insert with an 80° included angle and 0° relief fits standard external holders and boring bars when form, clearance angle, tolerance class, fastening, size and thickness match. The rhombic shape and cylindrical hole facilitate secure clamping and simple positioning, while the double-sided chipbreaker offers predictable chip control and can reduce inventory by providing two usable cutting positions. This compatibility simplifies toolset management on the shopfloor and supports faster changeovers in multi-operation cells.

Practical benefits for workshop productivity and process reliability

Beyond material advantages, the insert’s geometry and grade support stable chip formation and consistent surface finish, which benefits downstream operations and reduces rework. The double-sided design enhances cost-effectiveness by extending usable life per insert and the carbide core maintains cutting-edge strength at typical turning speeds. Technical advice and matching holder recommendations are available from Metav Werkzeuge to ensure the selected chipbreaker and grade align with component material and machining strategy, helping to optimise throughput and tool utilisation.

FAQ

What benefits does the AH905 coating provide?
The AH905 PVD-coated grade improves wear resistance and edge stability, helping the insert maintain a sharp cutting edge and reduce chipping during turning operations.

Which turning tasks is this insert intended for?
This rhombic insert is intended for both external and internal turning; the geometry and chipbreaker make it suitable where a sharp edge and process security are required.

Will the insert fit standard ISO holders?
Compatibility with ISO holders is determined by form, free angle, tolerance class, fastening, size and thickness; the CNMG160612 is manufactured to ISO dimensions and is compatible when the corresponding holder matches these parameters.

How does the double-sided chipbreaker affect tool use?
The double-sided chipbreaker offers repeatable chip control and extends usable life by allowing indexing to a second cutting position, increasing cost efficiency per insert.

How can the product be identified for reordering?
Use the designation CNMG160612 AH905 and the article number 6859353 or SKU 6859353-Tungaloy to ensure the correct Tungaloy turning insert is specified.
