SNMG190612 AH120 indexable turning insert by Tungaloy — PVD-coated carbide, square 19 mm

The SNMG190612 AH120 is an ISO-standard square indexable insert for external and internal turning, designed to deliver a sharp cutting edge and stable chip control in a wide range of industrial turning operations.

• PVD-coated carbide for wear resistance
• Sharp cutting edge with 1.2 mm corner radius
• Double-sided chipbreaker for stable chip control
• ISO-standard square insert, 19 mm inscribed circle

Consistent cutting performance through advanced coating and substrate

The insert combines a PVD coating with a robust carbide substrate to provide reliable wear resistance and preserve a keen cutting edge under continuous use. This surface treatment reduces abrasive wear and helps to maintain dimensional accuracy for longer tool life, which in turn minimises downtime. Designed as an ISO-standard insert, the component supports predictable replacement cycles and simplifies inventory management in production environments. The result is a measurable improvement in process stability and reproducible part quality.

Geometry engineered for secure clamping and chip control

A 1.2 mm corner radius and a dedicated double-sided chipbreaker deliver controlled chip formation and improved surface finish during both light and interrupted cuts. The square format with a cylindrical hole ensures secure seating and straightforward orientation in compatible tool holders, while the 0° clearance angle supports applications where reduced radial relief benefits workpiece integrity. These geometric details translate into fewer edge failures and a reliable cutting action that protects the workpiece and holder interface.

ISO compatibility for easy workshop integration

Built to the ISO designation SNMG190612, the insert fits established clamping systems where form, clearance angle, tolerance class, fixing and thickness determine compatibility. With an inscribed circle of 19 mm and a plate thickness of 6.35 mm, the component integrates into standard turning tool assemblies and tooling stocks without complex adjustments. The insert's PVD-coated carbide composition and stable cutting-edge design make it suitable for a broad range of turning tasks where process security and repeatability are priorities.

FAQ

What material is the SNMG190612 AH120 intended for?
The SNMG190612 AH120 insert is a PVD-coated carbide grade developed for general turning tasks where a sharp cutting edge and process security are required; specific workpiece materials should be matched with the AH120 grade based on machining conditions.

How is the insert clamped in the holder?
Clamping depends on holder form and tolerance; the SNMG190612 features a cylindrical hole and standard ISO geometry to allow secure seating in compatible square-indexable turning holders.

Can the insert be indexed to present a new cutting edge?
Yes, the SNMG190612 is double-sided and indexable, enabling rotation to a fresh edge to extend usable life and reduce tooling costs.

Which dimensions define compatibility with tool holders?
Compatibility is determined by the ISO designation SNMG190612, the 19 mm inscribed circle, 6.35 mm thickness and the 0° clearance angle; these values should be confirmed against the holder specification.

Is the AH120 coating suitable for interrupted cuts?
The AH120 PVD-coated grade is designed for wear and breakage resistance, making it appropriate for applications where a robust cutting edge and process reliability are required, including many interrupted cutting scenarios.
