SNMG120404 AH6225 Tungaloy indexable turning insert — PVD-coated carbide, 0.4 mm corner radius

The SNMG120404 AH6225 is an ISO‑standard square insert designed for versatile external and internal turning, offering a sharp yet stable cutting edge for changing stainless steel machining conditions.

• PVD-coated carbide grade AH6225
• Universal for stainless steel machining
• 0.4 mm corner radius for precise profiles
• Double-sided for economical indexing
• ISO SNMG120404, square 12 mm size

Consistent cutting performance for stainless steels

The PVD coating on the carbide substrate provides a hard, wear‑resistant surface that improves heat resistance and reduces built‑up edge when machining stainless steel. This insert combines a sharp cutting edge with inherent stability, which helps maintain dimensional accuracy during medium machining operations. The result is dependable surface finish and fewer interruptions for insert changes, supporting steady production flow and lower overall machining costs.

Secure seating and compatibility with ISO holders

Compatibility with a toolholder depends on form, clearance, tolerance class, fastening method, size and thickness; the ISO SNMG120404 geometry ensures interchangeability with standard external holders and boring bars. The insert’s cylindrical hole and 90° seating angle provide reliable clamping force and repeatable positioning, while the 0° clearance specification suits general turning setups where positive rake seating is required. These features simplify setup and reduce the need for bespoke adaptions.

Economical indexing and predictable tool life

Being double-sided offers two usable cutting edges per face, increasing the number of effective indexings before disposal and enhancing cost efficiency per edge. The 0.4 mm corner radius permits precise profile generation without compromising edge strength, and the 4.76 mm thickness contributes to mechanical rigidity under variable cutting conditions. Together, these attributes help achieve longer uninterrupted runs and predictable maintenance intervals.

Practical selection advice for workshop planners

Select the AH6225 grade when a balance between sharpness and wear resistance is needed for a range of stainless steels under fluctuating operating conditions. Matching the insert’s square 12 mm size and tolerance to the holder specification avoids seating errors and improves repeatability. For mixed production lots or frequent tool changes, the combination of PVD-coated surface and double-sided economy supports high process uptime and straightforward stock management.

FAQ

What materials is the insert suitable for?
The SNMG120404 AH6225 insert is designed primarily for machining stainless steel; the PVD‑coated carbide offers improved resistance to heat and adhesion typical of these alloys.

How many usable edges does the insert provide?
This square, double‑sided insert provides multiple indexing positions, offering economical use of each insert before disposal.

What determines compatibility with a toolholder?
Compatibility is defined by the insert form, clearance angle, tolerance class, fastening method, size and thickness; the ISO geometry of this insert aligns with standard holders when these parameters match.

Does the 0.4 mm corner radius limit profile capability?
The 0.4 mm corner radius balances profile precision and edge strength, allowing accurate small‑radius features without excessive chipping risk.

Is the insert suitable for internal turning as well as external turning?
Yes, the insert’s ISO geometry and cylindrical hole allow use in appropriate boring bars for internal turning, provided the holder matches the insert’s dimensions and tolerance.
