SNMG120412 AH6225 Tungaloy insert — ISO SNMG indexable turning insert, PVD-coated carbide, 90°

A SNMG120412 AH6225 Tungaloy insert ideal for external and internal turning, engineered to deliver a sharp, wear-resistant cutting edge for medium machining of stainless steels

• ISO SNMG 120412 geometry, 90° shape
• PVD-coated carbide grade AH6225
• Designed for stainless steels, universal use
• Double-sided insert with central cylindrical hole

Consistent cutting performance for stainless steels

The AH6225 grade is a PVD-coated carbide designed as a universal solution for stainless steels, providing a balance between edge sharpness and robustness under varying conditions. The coating improves surface hardness and thermal resistance, which reduces flank wear and extends tool life during medium cutting operations. For customers seeking predictable results, the combination of a stable carbide substrate and the PVD layer contributes to reliable machining and consistent component quality without frequent tool changes.

Lower running costs through multiple edges and secure clamping

A double-sided construction increases the number of usable cutting edges, improving cost efficiency per indexable edge. The insert’s cylindrical hole and SNMG geometry at 90° ensure secure clamping in compatible holders, reducing vibration and promoting dimensional stability. The 1.2 mm nose radius helps maintain edge strength while allowing acceptable surface finish, and the 0° clearance angle suits common holder designs. Choosing an insert with these traits supports longer uninterrupted runs and fewer set-ups on the shop floor.

Easy integration into existing turning systems and practical guidance

This indexable insert integrates into a standard turning system comprising a matching external holder or boring bar, an underlay/clamping set and spare fastening screws. Compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness, so selecting the correct holder is essential for optimal performance. For varied materials or unstable setups, select the chipbreaker and grade to suit the machining strategy; the built-in chip control and universal grade make this insert a sound choice for many turning tasks while maintaining process security.

FAQ

Which materials is the insert suited for? The SNMG120412 AH6225 Tungaloy insert is designed primarily for machining stainless steels, offering a universal grade that handles medium cutting and changing conditions.

What are the key dimensions to check for holder compatibility? Check the corner radius (1.2 mm), insert size (12 mm), thickness (4.76 mm) and the 90° geometry to ensure the holder matches the SNMG120412 dimensions and the 0° clearance angle.

Is the insert reversible or single-use? This insert is double-sided, providing multiple usable cutting edges before reconditioning or disposal, which improves cost-efficiency in typical turning applications.

How is the insert secured in the toolholder? Clamping is achieved via the central cylindrical hole; secure fixation depends on matching the holder’s fastening method and tolerance class to the SNMG120412 geometry.

Which chipbreaker and grade should be chosen for difficult stainless steel conditions? Select the chipbreaker and the AH6225 grade according to material ductility, cut depth and stability; AH6225 offers a balanced edge for variable conditions and good chip control.
