SNMG190612 AH120 SNMG 190612 AH120 turning insert for turning (PVD-coated carbide, 90° square) – Tungaloy

The SNMG190612 AH120 is an ISO-standard turning insert intended for reliable external and internal turning, combining a hard-wearing PVD-coated carbide grade with a double-sided chipbreaker for consistent cutting and process security.

• PVD-coated carbide for high wear resistance
• Double-sided chipbreaker for flexible machining
• 90° square geometry for secure clamping
• Cylindrical hole for standard screw fixation

Maximise uptime with a wear-resistant PVD grade

The AH120 grade is a PVD-coated carbide selected for high resistance to wear and chipping under demanding turning conditions. The coating reduces flank wear and preserves a sharp cutting edge, which translates into longer intervals between indexings and fewer unplanned stops. For manufacturers requiring reproducible results, this combination supports a stable cycle time and predictable tool life, so process planners can rely on consistent component quality and lower overall machining cost per part.

Quick selection and secure clamping for efficient changeovers

Designed to the ISO SNMG format, the insert features a 90° geometry, a cylindrical hole for screw fixation and a plate thickness of 6.35 mm, enabling straightforward compatibility checks with standard holders. The stamped nominal size of 19 mm and a corner radius of 1.2 mm provide a balance between edge strength and achievable surface finish. The specified 0° relief angle supports finishing cuts where dimensional accuracy and a fine external surface are priorities. Clear dimensional data simplifies holder selection and reduces set-up time on production lines.

Versatile chip control and application-focused performance

The double-sided chipbreaker offers effective chip segmentation for general turning operations, supporting both external and internal machining tasks. In practice, this reduces the risk of long, stringy chips and helps maintain a consistent cutting environment, improving surface finish and tool life. The insert forms part of a system—insert, suitable external holder or boring bar, shim/clamp set and fastening screw—and is best applied where a sharp edge and process security are required.

FAQ

What materials is this insert best suited for?
The SNMG190612 AH120 insert from Tungaloy is a PVD-coated carbide designed for general turning applications where a sharp cutting edge and process security are required; final selection should consider workpiece material and cutting parameters.

How does the double-sided chipbreaker affect machining?
The double-sided chipbreaker on the SNMG190612 AH120 promotes controlled chip formation, improving surface finish and reducing chip-related interruptions during turning operations.

Can the insert be used in standard ISO SNMG holders?
Yes, the SNMG190612 designation corresponds to ISO geometry; compatibility with a holder depends on form, relief angle, tolerance class, attachment style, size and thickness—check these dimensions against the chosen holder.

What does the corner radius of 1.2 mm influence?
A corner radius of 1.2 mm increases edge strength and helps achieve a robust cutting profile, which is beneficial for improving tool life and reducing chipping on interrupted cuts.
