SNMG120412 AH6225 ISO turning insert for turning applications — Tungaloy

The SNMG120412 AH6225 is an ISO-standard turning insert designed for external and internal turning; engineered as a square, double-sided indexable insert with a cylindrical hole for secure clamping.

• PVD-coated carbide grade AH6225
• Universal grade for rostfreier Stahl
• 1.2 mm nose radius for smooth finishes
• Double-sided chipbreaker, cylindrical hole

Consistent machining performance where conditions vary

The PVD-coated AH6225 grade is developed to provide a sharp yet robust cutting edge, optimised for medium cutting conditions and changing job requirements. As a result, the indexable insert maintains dimensional stability and reduces the risk of premature edge breakdown when machining rostfreier Stahl. The PVD layer improves wear resistance and helps to control built-up edge; the combination of coating and substrate supports prolonged tool life and predictable tool-change intervals, which contributes to higher process reliability and lower overall manufacturing costs.

Fast integration into ISO toolholder systems for efficient set-up

Designed to the ISO designation SNMG120412, this insert fits standard external holders and boring bars where compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness. The insert’s cylindrical hole and 90° geometry enable straightforward positioning and repeatable clamping, while the double-sided format doubles the usable life per insert. For workshops aiming to reduce set-up complexity, the ISO conformity means fewer special holders are needed and changeovers can be completed quickly, supporting higher machine utilisation and shorter cycle times.

Improved surface quality and predictable chip control

With a 1.2 mm nose radius and a dedicated double-sided chipbreaker, the insert produces consistent surface finishes while managing chip formation during turning. A modest radius offers a balance between edge strength and finish quality; larger radii increase stability, while the chipbreaker pattern promotes segmenting and evacuation of swarf. The insert’s 4.76 mm thickness contributes to rigidity under load, helping to reduce vibration and chatter. Together these attributes support repeatable results and efficient production runs on rostfreier Stahl components.
