CNMG090404 AH6225 CNMG indexable turning insert for Drehen by Tungaloy — PVD-coated carbide, 0.4 mm radius

The CNMG090404 AH6225 is an ISO rhombic indexable turning insert designed for external and internal turning, optimised for machining stainless steel with a sharp yet stable cutting edge.

• ISO rhombic CNMG 80° geometry
• PVD-coated cemented carbide AH6225
• 0.4 mm nose radius for accurate profiling
• Double-sided chipbreaker with cylindrical hole

Consistent cutting performance and prolonged tool life

The insert combines a PVD-coated surface with a robust cemented carbide core in grade AH6225, delivering a balanced mix of edge sharpness and stability that supports medium machining operations. The coating reduces built-up edge and improves wear resistance under variable conditions, which translates into more predictable tool life and fewer unscheduled indexings. For manufacturers seeking reduced cycle-time variation, the combination of grade and geometry contributes to reliable part quality and repeatable results when tackling stainless steel.

Interchangeability and secure clamping in ISO tool systems

Compatibility with standard holders is governed by insert form, relief angle, tolerance class, fastening and thickness; this ISO-normed CNMG insert fits common CNMG-compatible external holders and boring bars when these parameters match. The design includes a cylindrical hole for positive location and stable clamping, which simplifies tool setting and reduces run-out risk. As a result, workshop setups become more consistent, changeover times decrease and process stability improves, supporting higher first-pass yield in small- to medium-batch production.

Application advantages for efficient stainless steel turning

With an 80° geometry and a 0.4 mm nose radius, the insert offers a robust cutting profile that resists chipping while allowing precise contouring. The double-sided chipbreaker enables two effective cutting edges per index, increasing economic life per insert and lowering tooling costs. This insert is especially suitable for diverse turning tasks — from finishing to light roughing — where stainless steel is involved and where stable chip control and surface finish matter. For complex material mixes or special machining strategies, further technical guidance is available from Metav Werkzeuge to match chipbreaker and cutting data to the workpiece.

FAQ

Which materials is this insert suited for?
The CNMG090404 AH6225 insert from Tungaloy is optimised for stainless steel; its grade and coating offer good edge stability and wear resistance for a broad range of stainless steel turning tasks.

How is compatibility with toolholders ensured?
Compatibility depends on the ISO CNMG form, relief angle, tolerance class, fastening method, size and thickness; a matching CNMG-compatible holder or boring bar is required for correct clamping of the CNMG090404 AH6225.

What benefits does the AH6225 grade provide?
AH6225 is a PVD-coated cemented carbide grade designed to provide a sharp yet stable cutting edge at medium cutting conditions, improving surface finish and process reliability when machining stainless steel.

Can this insert be used for both external and internal turning?
Yes, the CNMG090404 AH6225 is suitable for both external and internal turning applications when mounted in the appropriate CNMG-compatible holder.

What does the 0.4 mm nose radius influence?
A 0.4 mm nose radius balances edge strength and profile accuracy, offering improved surface finish over larger radii while maintaining sufficient robustness for mid-range cuts.
