SNMG120404 AH6225 indexable turning insert by Tungaloy — ISO turning insert, 90° square form

The SNMG120404 AH6225 is an ISO‑standard indexable insert for turning, engineered for medium‑duty machining of stainless steel with a sharp yet robust cutting edge.

• ISO SNMG geometry, 90° cutting angle
• PVD‑coated carbide grade AH6225
• Double‑sided chipbreaker for stable machining
• 12 mm inscribed circle, 4.76 mm thickness

Increase throughput with a stable, sharp cutting edge

The PVD‑coated carbide grade AH6225 provides a balance between edge sharpness and durability, specifically tuned for stainless steel machining. This combination enables reproducible cutting results under varying conditions, which can translate into fewer tool changes and a steadier cycle time. The insert’s engineered cutting edge supports consistent surface quality while maintaining productivity during medium‑duty turning.

Ensure predictable holder compatibility and secure clamping

Designed to the ISO SNMG form, the insert aligns with standard indexable holder geometries; compatibility depends on form, relief angle, tolerance class, fastening, size and thickness. The square form with a cylindrical hole and a nominal 90° cutting angle allows straightforward seating in compatible external holders or boring bars. Clear dimensional parameters reduce setup uncertainty and aid faster tool mounting and repeatable clamping.

Flexible grade and chip control for varying shop conditions

The universal grade AH6225 is intended for diverse turning tasks on stainless steel, offering a compromise between edge resistance and cutting action. The double‑sided chipbreaker assists chip control in interrupted and continuous cuts, reducing the likelihood of built‑up edge and improving process stability. Selecting a matching chipbreaker and holder rigidity will maximise the grade’s advantage under changing process dynamics.

Minimise downtime with durable indexable design

The square, double‑sided construction provides additional indexing options to extend usable life per insert, while the PVD‑coating enhances wear resistance on the flank and rake faces. The combination of a modest 0.4 mm corner radius and a 4.76 mm thickness gives a stable cutting geometry that tolerates moderate vibration and supports repeatable part quality. Technical advisors can assist in matching the insert to the correct clamping set and replacement screw specification.

FAQ

What materials is this insert designed for?
The SNMG120404 AH6225 Tungaloy insert is optimised for stainless steel and comparable alloys, with the AH6225 grade tuned for medium‑duty turning.

How is holder compatibility determined?
Compatibility depends on the insert form, relief angle, tolerance class, fastening method, size and thickness; the SNMG120404 conforms to ISO SNMG geometry for straightforward matching.

How many usable cutting edges does the insert offer?
The double‑sided construction of the SNMG120404 AH6225 provides multiple indexable edges, extending service life and reducing the frequency of replacements.

When is the 0.4 mm corner radius recommended?
A 0.4 mm corner radius suits medium‑duty turning where a balance between edge strength and surface finish is required; it reduces the risk of chipping compared with very small radii.

Does the PVD coating improve performance?
Yes, the PVD‑coating on the AH6225 grade enhances wear resistance on contact faces and contributes to a more stable cutting edge under fluctuating conditions.
