SNMG 120404 AH110 ISO turning insert — PVD-coated carbide for turning (Tungaloy)

The SNMG120404 AH110 is an ISO-indexable turning insert designed for external and internal turning with a square, 12 mm form and a cylindrical hole for secure clamping.

• SNMG120404 form, 90° cutting geometry
• PVD-coated carbide grade AH110 for wear resistance
• Double-sided chipbreaker for consistent chips
• Cylindrical-holed, indexable square insert 4.76 mm thick

Delivering consistent tool life and surface quality

The combination of the AH110 grade and PVD coating ensures a balance between wear resistance and a sharp cutting edge, which in practice means fewer insert changes and more predictable production runs. The PVD layer reduces flank wear and helps maintain dimensional accuracy over longer cutting distances; this is especially important in high-volume turning where downtime is costly. The result is improved component repeatability and reduced quality sorting.

Predictable chip formation for safer machining

A double-sided chipbreaker design provides controlled chip formation and evacuation in a variety of turning operations. Stable chips reduce the risk of workpiece damage and make coolant and chip-conveyor requirements more predictable, contributing to smoother shifts and fewer interruptions. Selecting an appropriate chipbreaker and grade supports both process reliability and consistent surface finish in repeated production cycles.

Fast integration into ISO tooling systems to save set-up time

As an ISO-standard insert, the SNMG120404 AH110 matches common indexable holders when form, 0° relief angle, tolerance class, clamping method, size and thickness are aligned. The square 12 mm plate with a 0.4 mm corner radius and 4.76 mm thickness is compatible with many external holders and boring bars, which simplifies inventory and shortens set-up times. Clear matching of holder and insert minimises rework and contributes to a smooth tool-change routine.

Application focus and recommended process approach

This PVD-coated carbide insert is intended where a sharp edge and process security are required; it is suitable for general turning tasks when the cutting data and holder stability are chosen accordingly. For best results, pair the insert with a holder and cutting parameters that reflect the chosen chipbreaker, workpiece material and desired surface finish. The combination supports efficient material removal while preserving edge integrity during intermittent cuts.

FAQ

What holder types are compatible with this insert? Compatibility depends on holder form, relief angle, tolerance class, clamping method, size and thickness; the SNMG120404 AH110 matches standard ISO SNMG holders when these parameters align.

Which benefits does the AH110 grade provide? The AH110 grade on the SNMG120404 AH110 offers wear resistance and edge stability due to its PVD coating, supporting longer tool life and consistent surface finish.

Is the insert indexable on both sides? Yes, the insert features a double-sided design allowing indexing to the second cutting edge, which extends useful life per insert.

How does the 0° relief angle affect cutting? A 0° relief angle gives a neutral geometry suitable for general turning; it requires appropriate holder support to prevent rubbing and to maintain accuracy.

What are the main features to check when replacing inserts? Check geometry (SNMG120404), corner radius, plate thickness (4.76 mm), hole type (cylindrical) and chipbreaker; matching these ensures correct seating and repeatable results with the SNMG120404 AH110.
