SNMG120408 AH6225 – Turning insert for turning, Tungaloy

The SNMG120408 AH6225 is an ISO-indexable turning insert engineered for external and internal turning, offering a balance of a sharp cutting edge and edge stability for medium cutting conditions.

• PVD-coated carbide AH6225
• Universal for stainless steel
• 0.8 mm corner radius
• ISO SNMG 120408, 4.76 mm thick

Consistent cutting performance for stainless steel machining

The grade combines a PVD-coated surface with a wear-resistant carbide substrate to provide a predictable and durable cutting edge. Designed as a universal grade for stainless steel, AH6225 delivers a sharp cutting action while maintaining edge stability during interrupted cuts and variable feeds. The result is improved process reliability and reduced scrap rates because tool life is extended and surface finish is more consistent. The inclusion of a well‑matched chipbreaker aids in chip control for both finish and semi‑finishing operations, so cycle times can be optimised without compromising component quality.

Geometry and holder compatibility that reduce set-up time

The insert’s SNMG120408 geometry and square form (12 mm inscribed size) are ISO‑standardised to simplify toolholder selection: compatibility is determined by shape, relief, tolerance class, clamping and thickness. With a 0° relief angle and a 0.8 mm corner radius, the insert is suited to stable medium‑duty turning where a balance between strength and edge acuity is required. The plate is double‑sided and 4.76 mm thick, with a cylindrical central hole for secure clamping; these features make indexing straightforward and cost‑effective, as each edge can be used before replacement, lowering unit tooling costs.

Practical benefits on the shop floor and support options

By combining a stable cutting edge with a double-sided chipbreaker, this insert reduces the frequency of insert changes and supports consistent surface finishes on rotational parts. The indexable design also simplifies inventory management and lowers per‑part tooling cost. For machining scenarios with variable stability or mixed batches, the AH6225 grade is a pragmatic choice that balances tool life and cutting performance.
