SNMG120408 AH6225 Turning Insert (ISO SNMG120408) – Tungaloy

A SNMG120408 AH6225 indexable turning insert designed for external and internal turning applications, offering a sharp yet robust cutting edge optimised for rostfreier Stahl.

• PVD-coated AH6225 for rostfreier Stahl
• 0° clearance for stable cutting
• Double-sided chipbreaker for predictable chips
• ISO SNMG120408, square insert with 90° nose

Reliable mid-range performance for rostfreier Stahl machining

The insert’s PVD-coated carbide matrix (grade AH6225) is developed as a universal solution for machining rostfreier Stahl, combining a sharp cutting edge with enhanced wear resistance. This balance reduces the frequency of index changes and supports consistent component quality in batch production. By using a coated grade optimised for variable conditions, process windows widen: feed and cut variations are better tolerated, which increases net productive time and lowers downtime for tool changes. The material choice and coating technology together provide improved thermal stability and edge life during common turning operations.

Geometry and chip control that stabilise the machining process

A geometry configured with 0° clearance and a 90° wedge angle provides secure engagement and predictable cutting forces, while the corner radius 0.8 mm gives a compromise between edge strength and surface finish. The double-sided chipbreaker promotes consistent chip formation across a range of feeds, aiding evacuation and reducing the risk of built-up edge on rostfreier Stahl. The square plate form with a cylindrical hole ensures accurate seating in compatible holders and simplifies indexing procedures, which contributes to repeatable clamping and process security in turning centres and lathes.

System integration, handling and shop-floor benefits

As an ISO-designated insert, ISO SNMG120408 integrates into standard holders and boring bars when form, clearance, tolerance class, fastening and plate thickness match. The insert is part of a system that typically includes the appropriate external holder or boring bar, a backing/clamping set and replacement screws, enabling straightforward maintenance and stock management. For production planners, the insert’s universal grade reduces the need for multiple dedicated grades, simplifying inventory while maintaining surface quality and tool life. If application parameters are unclear, technical consultation is recommended to select the optimal chipbreaker and cutting data for the specific setup.
