SNMG120416 AH6225 ISO indexable turning insert by Tungaloy — PVD‑coated carbide, 90° square geometry

The SNMG120416 AH6225 is an ISO‑standard indexable turning insert engineered for external and internal turning, optimised for machining stainless steels under variable conditions.

• PVD-coated carbide grade AH6225
• 1.6 mm corner radius for robustness
• ISO SNMG120416 square insert, 90° geometry
• Double-sided chipbreaker, with cylindrical hole

High‑performance grade for stainless steel turning

The AH6225 grade is a PVD‑coated carbide developed as a universal solution for stainless steels, offering a balance between a sharp cutting edge and edge stability under changing cutting conditions. This combination reduces built‑up edge and improves surface finish while maintaining acceptable tool life during medium‑duty operations. The coating supports consistent wear behaviour, which translates into fewer unscheduled index changes and more predictable machining cycles — a clear advantage where process reliability and throughput matter.

Geometry and compatibility that reduce setup time

The square SNMG120416 geometry with a 90° approach and a 1.6 mm corner radius provides strong support in radial cuts and simple programming for facing and profiling operations. The insert is double‑sided and features a cylindrical hole for positive clamping; compatibility with holders depends on form, clearance angle, tolerance class, fastening method, size and thickness. The 4.76 mm thickness and ISO dimensions ensure straightforward replacement in standard external holders and boring bars, enabling rapid changeovers and lower tooling inventory complexity.

Practical system approach for predictable results

Used as part of a complete system — insert, matching external holder or boring bar, shim/clamp set and replacement screws — this insert is intended to deliver stable chip formation and good surface integrity. The double‑sided chipbreaker offers symmetric cutting edges that help maintain chip control when machining long or interrupted cuts. For best results, select the chipbreaker style and grade according to workpiece stability and cutting parameters; this approach minimises tool wear and optimises cycle times for batch and single‑piece production alike.

FAQ

What materials is this insert intended for?
The AH6225 grade is formulated for machining stainless steels; it provides a balance of sharpness and edge stability for medium machining tasks.

Is the SNMG120416 compatible with standard ISO holders?
Yes, the SNMG120416 follows ISO dimensions; compatibility depends on holder form, clearance angle, tolerance class, fastening and thickness — matching the insert to a suitable external holder or boring bar is recommended.

How does the 1.6 mm corner radius affect performance?
A 1.6 mm corner radius increases edge strength for more robust cuts while still allowing good surface finish; it is suitable for general turning where a balance of strength and finish is required.

How many usable cutting edges are available per insert?
The indexable SNMG is double‑sided, offering multiple cutting edges before indexing; the exact number of operations depends on cutting conditions and workpiece material.

Which chipbreaker should be chosen for long turning operations?
For longer, continuous cuts in stainless steels, select the chipbreaker that supports stable, segmented chip formation; the double‑sided chipbreaker on this insert provides improved chip control in many turning scenarios.
