SNMG120404 AH6225 indexable insert for turning — Tungaloy

The SNMG120404 AH6225 indexable insert is an ISO-standard, square 90° turning insert designed for medium finishing and general-purpose turning of stainless steels, offering a sharp yet stable cutting edge in varying conditions.

• ISO SNMG 120404 geometry for standard holders
• PVD-coated carbide AH6225 for stainless steel
• Double-sided chipbreaker for stable cutting
• Cylindrical hole for secure clamping

Consistent cutting in stainless steel with a universal PVD grade

The combination of a PVD-coated surface and the AH6225 carbide composition provides a balance between edge sharpness and wear resistance tailored for stainless steels. This grade is formulated to maintain a sharp cutting edge under changing cutting conditions, which translates into reliable surface finishes and extended insert life during medium machining operations. The coating reduces adhesion and built-up edge formation on difficult-to-machine alloys, helping to sustain cutting parameters and lower the frequency of insert changes.

Predictable compatibility and secure clamping for faster setup

The insert follows the ISO SNMG 120404 geometry and a square 90° shape, ensuring interchangeability with corresponding standard holders. The insert features a cylindrical hole for positive seating and a 0.4 mm corner radius, which provides a compromise between edge strength and detail in contour work. Because compatibility is determined by form, relief angle, tolerance class, fastening, size and thickness, the standardised geometry simplifies tool procurement and reduces set-up time on the shop floor.

Economical operation through indexability and chip control

Being double-sided, the insert offers two usable cutting edges per index position, enabling economical tool usage and fewer index changes. The integrated chipbreaker geometry promotes predictable chip formation and evacuation; stable chips reduce the risk of surface damage and tool interference during turning. In practice, the result is less downtime for insert replacement and a more continuous production flow, which supports cost-efficient machining without sacrificing process reliability.

Practical selection and workshop guidance

Selection of the correct chipbreaker and grade should be aligned with workpiece material, machining type and machine stability; the AH6225 grade and the PVD-coated carbide construction are optimised for a broad range of stainless steel alloys, but performance improves further when feed rates and speeds are tuned to the alloy and fixturing.

FAQ

What materials is this insert suited for?
The SNMG120404 AH6225 indexable insert is designed primarily for stainless steels and provides a balanced combination of sharpness and wear resistance for medium turning operations.

How does the AH6225 grade improve machining of stainless steel?
The AH6225 PVD-coated carbide grade reduces adhesion and supports a stable cutting edge under variable conditions, which helps to limit built-up edge and maintain consistent surface quality with longer edge life.

Can the insert be used in standard ISO SNMG holders?
Yes. The ISO SNMG 120404 geometry and the cylindrical hole ensure compatibility with corresponding standard external holders, provided form, relief angle, tolerance class, fastening, size and thickness match the holder specifications.
