SNMG190616 AH120 turning insert, square form by Tungaloy

SNMG190616 AH120 is an ISO-standard indexable insert for external and internal turning, engineered for process-secure, wear- and break-resistant cutting in demanding production environments

• SNMG form, ISO 190616, 90° geometry
• PVD-coated cemented carbide AH120 grade
• Double-sided chipbreaker, sharp cutting edge
• Compatible with standard external/internal holders

Predictable mounting and robust shoulder turning for continuous production

The SNMG190616 conforms to ISO 190616, offering a clearly defined form and tolerance set that simplifies tool selection and reduces setup variability. The 90° geometry provides a strong shoulder angle that supports heavier axial forces during facing and shoulder operations, while the square shape increases indexing options to extend tool life. Specified values for plate size and thickness ensure repeatable mounting in compatible holders, so production runs remain stable and downtime is minimised.

Controlled chip flow and surface quality from a balanced corner radius

With a 1.6 mm radius and a double-sided chipbreaker, the insert balances edge strength and surface finish: the corner radius resists edge chipping on interrupted cuts, while the chipbreaker shapes and controls chips to prevent entanglement and ensure consistent surface quality. The 0° relief angle gives a positive cutting stance for many turning tasks; the chipbreaker geometry is particularly beneficial where reliable swarf evacuation and predictable tool behaviour are required, reducing rework and improving first-pass yield.

Durable grade and coating for extended tool life and process security

The cutting edge is made from cemented carbide and finished with a PVD coating in the AH120 grade, formulated for wear resistance and fracture toughness in turning operations. This combination supports a sharp cutting edge that maintains dimensional accuracy over longer cycles and offers enhanced process security under varying cutting conditions. For best results, pair the insert with a holder that matches the form, clearance angle and tolerance class so the system delivers consistent components and lower tooling costs per part.

FAQ

What operations are suitable for this insert? The SNMG190616 AH120 insert is designed for external and internal turning; it is particularly effective for shoulder turning and general finishing or medium-duty roughing where a 90° geometry is advantageous.

How does the AH120 grade improve performance? The AH120 grade combines a PVD coating with a wear-resistant cemented carbide substrate to provide enhanced edge strength and fracture resistance, resulting in longer tool life and greater process security during turning.

Which holders are compatible with this insert? Compatibility depends on holder form, clearance (relief) angle, tolerance class, clamping method, size and thickness; Metav Werkzeuge can recommend matched external or boring holders for the SNMG190616 insert.

How does the chipbreaker affect chip control? The double-sided chipbreaker on this insert shapes chips to ensure controlled evacuation and reduces the risk of chip accumulation, improving safety and surface quality on continuous and interrupted cuts.

Is the insert indexed or single-use? The SNMG190616 is an indexable insert with multiple usable cutting edges; the square form provides several indexing positions to extend effective tool life.
