SNMG120412 AH120 indexable turning insert, 90° square geometry by Tungaloy

A SNMG120412 AH120 indexable insert designed for turning operations, offering a wear-resistant PVD coating and a robust, ISO-compatible form for consistent, sharp cutting performance.

• PVD-coated AH120 for excellent wear resistance
• ISO SNMG120412 format, 90° square geometry
• Double-sided chipbreaker for consistent chips
• Cylindrical hole for secure clamping

Reliable cutting performance through PVD-coated carbide

The insert is manufactured from carbide and finished with a PVD coating, identified by grade AH120, which provides a balanced combination of wear resistance and edge toughness. This composition reduces flank wear and extends tool life under typical turning conditions, so process stability is increased and unplanned tool changes are minimised. The result is a predictable output and reduced downtime in serial production.

ISO compatibility and secure clamping for quick integration

Designed to the ISO family format, the geometry ensures the insert fits standard holders where form, relief angle, tolerance class, fastening and thickness match. The 90° square shape and the cylindrical mounting hole allow straightforward clamping and simple handling during index changes. Compatibility with common external and internal turning holders shortens commissioning time and simplifies tool inventory.

Consistent chip control and surface quality for efficient cycles

Equipped with a double-sided chipbreaker and a corner radius of 1.2 mm, the insert controls chips reliably across a range of cutting conditions. Controlled chip formation improves coolant contact and reduces thermal load on the cutting edge, often resulting in a steadier surface finish and fewer interruptions for chip clearance. For applications requiring a sharp edge and high process security, this combination contributes directly to productivity.

System thinking: selection and assembly for best results

The insert forms part of a system consisting of the indexable plate, a matching external holder or boring bar, a clamping seat and replacement screws. Selecting the correct chipbreaker and grade for the workpiece material and machining stability is decisive: the AH120 grade is aimed at demanding turning tasks where both a sharp cutting edge and reproducible process behaviour are required. Consider holder rigidity and cutting parameters to get the most from the insert.

FAQ

What materials can this insert machine effectively? The AH120 PVD-coated carbide insert is suitable for a broad range of turning tasks; selection of the chipbreaker should match the workpiece material for optimal performance with the SNMG120412 AH120 insert.

How is the insert clamped in a holder? The SNMG120412 features a cylindrical mounting hole and square form, enabling secure clamping in compatible ISO holders and straightforward indexing when replacing edges.

What advantage does the AH120 grade offer? AH120 provides a balance of wear resistance and edge strength thanks to its PVD coating, delivering improved process stability and a longer effective tool life under standard turning conditions.

Is the insert reversible or single-use? This is a double-sided indexable insert, offering two usable cutting edges per side where the chipbreaker and geometry permit re-indexing for economical use.

Which chipbreaker should be selected for unstable setups? For lower rigidity or interrupted cuts, choose the chipbreaker and grade combination that emphasises edge strength and secure chip control; the AH120 grade is designed to maintain a sharp cutting edge with reliable process behaviour.
