SNMG 120408 AH6225 — Indexable turning insert, PVD-coated carbide, 90° (Tungaloy)

A compact SNMG 120408 AH6225 indexable insert designed for robust external and internal turning, optimised for rostfreier Stahl and varying machining conditions.

• PVD-coated carbide for rostfreier Stahl
• Sharp yet stable cutting edge
• Double-sided, square 90° geometry
• Cylindrical hole for secure clamping

Consistent mid-range turning performance for rostfreier Stahl

The PVD-coated carbide grade AH6225 combines a sharp cutting edge with structural toughness, delivering dependable results during medium cutting operations. The PVD-coated surface increases wear resistance while maintaining edge sharpness, which translates into fewer interruptions for tool changes and more predictable cycle times. For applications on rostfreier Stahl, this balance reduces chatter and supports uniform surface finish with stable tool life under fluctuating feeds and speeds.

Compatibility and secure clamping to maintain production uptime

Produced to ISO indexing dimensions, the square insert with a cylindrical hole and 90° geometry enables secure attachment in standard holders. Compatibility with a given holder depends on the insert’s form, relief angle, tolerance class, fastening method, size and thickness; matching these parameters ensures correct seating and repeatable accuracy. The double-sided layout allows indexing to fresh edges, improving economy per cutting edge and contributing to uninterrupted production.

Practical guidance for selection and application

The 0.8 mm corner radius provides a compromise between cutting strength and dimensional control, suitable for medium-depth turning and finishing passes where stability varies. With a plate thickness of 4.76 mm, the insert offers stiffness for conventional operations while remaining compatible with common ISO toolholders. Choose the doppelseitig chipbreaker style and AH6225 grade when machining rostfreier Stahl, and prefer a rigid setup for best surface quality and extended edge life.

FAQ

Which materials is this insert best suited for?
The SNMG120408 AH6225 insert is optimised as a universal grade for rostfreier Stahl, offering a balance of sharpness and edge stability for stainless applications.

How is the insert secured in the holder?
The insert uses a cylindrical hole and ISO indexing form; secure clamping depends on matching the insert’s form, relief angle, tolerance class, fastening method, size and thickness to the chosen holder.

What are the advantages of the AH6225 grade?
AH6225 is a PVD-coated carbide grade designed to provide a sharp yet resilient cutting edge for medium cutting, improving wear resistance and chip formation control in changing conditions.

When is the 0.8 mm corner radius appropriate?
A 0.8 mm corner radius suits medium stock-removal and turning operations where a compromise between edge strength and dimensional accuracy is required.

Is the SNMG120408 indexable and economical to use?
Yes; the square, double-sided insert can be indexed to expose fresh edges, which increases usable edge count and reduces tooling cost per component.
