CNMG090404 AH6235 ISO turning insert for external and internal turning — Tungaloy

A CNMG090404 AH6235 ISO-standard indexable insert designed for robust external and internal turning, optimised for stainless steel and interrupted cuts.

• PVD-coated carbide AH6235 grade
• Optimised for stainless steel and interrupted cuts
• Double-sided chipbreaker for stable chip control
• 0.4 mm corner radius, rhombic CNMG form

High-process stability for stainless-steel turning

The insert is engineered to support consistent results when machining stainless steel under challenging conditions. The PVD-coated carbide substrate of the AH6235 grade offers a balance of toughness and wear resistance, making it suitable for interrupted cuts and applications with increased risk of chipping. By combining a robust substrate with a tailored coating, the geometry maintains edge integrity over longer cycles, which reduces unplanned tool changes and contributes to a steadier production flow. The rhombic CNMG form with a 0.4 mm corner radius helps distribute cutting forces and supports repeatable dimensional accuracy.

Predictable chip control and extended service life

A clearly defined double-sided chipbreaker on this indexable insert promotes uniform chip formation and evacuation, which is particularly beneficial in variable feed and depth conditions. The 0° clearance angle and the CNMG090404 geometry ensure compatibility with a broad range of ISO holders; secure clamping is supported by the cylindrical hole design. These features together reduce the incidence of built-up edge and edge breakout, delivering smoother surface finishes and fewer rejects. The combination of chip control and the AH6235 grade leads to a measurable improvement in machining uptime and tool-life stability.

Easy integration into ISO tool systems and efficient inventory management

Being an ISO-standard insert simplifies selection of a matching external holder or boring bar: form, clearance, tolerance class, fixing method, size and thickness are the determining factors for compatibility. The plate’s 4.76 mm thickness, CNMG rhombic form and standard designation streamline stock-keeping and replacement procedures. For workshops running mixed materials, the insert’s versatility in handling interrupted cuts alongside stainless steels reduces the need for multiple specialised grades, supporting more economical tooling strategies and faster tool-change routines.

FAQ

What materials is this insert suitable for?
The CNMG090404 AH6235 Tungaloy insert is particularly suitable for stainless steel and for operations with interrupted cuts, thanks to the tough PVD-coated carbide grade.

How does the AH6235 grade affect performance?
AH6235 provides a balance of toughness and wear resistance; with the CNMG geometry it improves edge stability and reduces the risk of chipping in demanding turning tasks.

Is the plate compatible with standard CNMG holders?
Yes, the ISO designation and the rhombic CNMG form ensure compatibility with matching ISO external holders and boring bars when the holder matches form, size and clamping specifications.

What advantages does the double-sided chipbreaker provide?
The double-sided chipbreaker on this insert promotes consistent chip formation and evacuation, which supports better surface quality and fewer interruptions in production.

Which dimensions are critical when selecting a replacement?
Key dimensions to match are the plate size (09), corner radius (0.4 mm), thickness (4.76 mm) and the CNMG form; confirming these ensures secure clamping and correct cutting geometry.
