SNMG 190616 AH6225 Turning indexable insert by Tungaloy — 90° geometry, 1.6 mm corner radius

SNMG190616 AH6225 Tungaloy insert is an ISO-format indexable insert designed for general turning applications, especially where machining of stainless steels is required; its square form and standard fit enable straightforward integration into common external and internal turning toolholders.

• PVD-coated carbide AH6225 for stainless steel
• Double-sided chipbreaker for consistent chips
• Square ISO insert SNMG 190616 with cylindrical hole
• 1.6 mm corner radius and 90° cutting geometry

Optimised fit for standard ISO holders and secure clamping

Compatibility is ensured by the ISO dimensions and by matching the insert’s form, relief angle, tolerance class, fastening method, size and thickness to the chosen holder. The square plate with a cylindrical hole and 90° included angle gives reliable seating and repeatable positioning; this reduces setup variation and supports continuous production. The 0° relief angle and 1.6 mm radius are designed to deliver a balanced combination of strength and finish, so tool paths remain stable even when machining interrupted cuts or variable workpiece conditions.

Predictable cutting performance with a universal PVD grade

The AH6225 grade is a PVD-coated carbide developed as a universal solution for stainless steel: it presents a sharp yet stable cutting edge suited to medium machining parameters and fluctuating conditions. The double-sided chipbreaker promotes controlled chip formation and evacuation, reducing the risk of built-up edge and contributing to consistent surface quality. The coating improves wear resistance and thermal stability, which together extend effective tool life and increase process reliability during serial production.

Practical guidance for system setup and application

For best results, pair the indexable insert with a compatible external holder or boring bar, an appropriate shim or clamping kit, and the correct replacement screws; the system should be selected taking into account workpiece material, machining stability and desired surface finish. The insert is suitable for both external and internal turning when the correct chipbreaker and holder geometry are chosen. If process stability or material mix requires adaptation, adjustments to cutting parameters and coolant strategy will typically yield improved cycle times and repeatable quality.

FAQ

Is this insert suitable for stainless steel alloys?
The Tungaloy SNMG190616 AH6225 indexable insert is specified as a universal grade for stainless steel machining and is optimised to maintain a sharp, stable cutting edge under varying conditions.

Can the insert be used for internal turning on a boring bar?
Yes; the square SNMG format and the specified dimensions allow use in compatible holders and boring bars for internal turning when the holder provides sufficient support and rigidity.

What benefits does the PVD coating provide?
The PVD coating on the AH6225 grade enhances wear resistance and thermal stability, which supports longer tool life and more consistent cutting performance in stainless steel applications.

How does the chipbreaker contribute to process stability?
The double-sided chipbreaker promotes predictable chip formation and evacuation, reducing the likelihood of built-up edge and improving surface finish and cycle consistency.

Which components make up the basic tooling system for this insert?
A complete system comprises the indexable insert, a matching external holder or boring bar, an underlay or clamping set and the correct replacement screws; compatibility depends on form, relief angle and tolerance class of the holder
