SNMG120416 AH6225 Tungaloy turning insert — square 90°, PVD-coated carbide

The SNMG120416 AH6225 is an ISO-standard square indexable insert intended for external and internal turning, optimised for machining rostfreier Stahl in medium cutting conditions.

• ISO square insert SNMG120416 AH6225
• PVD-coated carbide for wear resistance
• 1.6 mm corner radius for repeatable edge stability
• Double-sided chipbreaker with cylindrical hole

Increased productivity through a balanced grade and geometry

The AH6225 grade is a PVD-coated carbide designed to provide a balance between edge sharpness and robustness for medium turning tasks. The combination of a sharp cutting edge and a controlled micro-geometry reduces built-up edge when machining rostfreier Stahl, while the surface coating improves wear resistance and heat management. PVD coating stands for a thin, hard layer applied in a vacuum process that enhances surface hardness and reduces friction; this translates into more consistent component finish and fewer tool changes, supporting a smoother production flow and predictable cycle times.

Simple integration into ISO tool systems for fast changeover

Being part of the ISO-standard turning insert family, the square SNMG120416 format and the central cylindrical hole ensure compatibility with a wide range of external holders and boring bars when matched by form, clearance angle and tolerance class. The insert is double-sided, offering economical indexability and straightforward reversal when one edge is worn. With a plate thickness of 4.76 mm and a visible 90° corner contact, setup is fast and repeatable; the cylindrical hole gives reliable clamping, reducing the risk of movement under cutting loads and enabling stable tool life.

Stable surface quality and controlled chip formation under varying conditions

The 1.6 mm corner radius supports a dependable surface finish while absorbing moderate cutting forces—ideal for finishing and general turning cycles. The double-sided chipbreaker assists in fragmenting chips consistently across changes in feed or material variations, which reduces the likelihood of entanglement and improves process safety. For shops facing variable batch sizes or mixed rostfreier Stahl alloys, this insert grade delivers repeatable performance and less process variance, contributing to uptime and quality assurance.

FAQ

What materials is this insert suitable for?
The SNMG120416 AH6225 insert is formulated for machining rostfreier Stahl; the AH6225 PVD-coated carbide provides a good compromise between sharpness and wear resistance for a range of stainless alloys.

How does the 1.6 mm corner radius affect part finish?
A 1.6 mm corner radius increases edge stability and supports a consistent surface finish while allowing for modest cutting depths, making it suitable for finishing and general turning tasks.

Is the insert reversible and economical to use?
Yes—this is a double-sided indexable insert; both edges can be used, which extends tool life per insert and reduces tooling costs per component.

Which holders are compatible with SNMG120416 inserts?
Compatibility depends on holder form, clamping style, clearance angle and tolerance class; the ISO-standard format and cylindrical hole of this insert allow fitting into common external holders and boring bars when those parameters match.
