CNMG190616 AH6235 Tungaloy — ISO turning insert for stainless steel, 80° rhombic, 1.6 mm radius

The CNMG190616 AH6235 Tungaloy is an ISO-standard rhombic indexable insert designed for external and internal turning, offering a tough PVD-coated carbide grade for interrupted cuts and applications with increased edge breakout risk.

• ISO rhombic insert CNMG190616
• PVD-coated carbide AH6235 for stainless steel
• 80° geometry, 1.6 mm corner radius
• Double-sided chipbreaker, cylindrical hole

High process security and material fit for stainless work

The combination of PVD-coated carbide and the AH6235 grade provides improved resistance to abrasive wear while preserving a tougher cutting edge for difficult materials such as stainless steel. The coating supports reduced tendency for built-up edge and extends usable tool life, which contributes to fewer tool changes and more predictable cycle times. As a result, the component quality and surface finish remain consistent even under demanding cutting conditions, supporting higher overall productivity.

Stable cutting in interrupted and challenging conditions

The rhombic 80° geometry and double-sided chipbreaker deliver reliable chip formation and evacuation during both continuous and interrupted cuts. A cylindrical hole ensures secure clamping in compatible holders, while the neutral relief angle (0°) contributes to a balanced cutting action suitable for varying feed rates. Together these features reduce the risk of edge breakout and minimise vibration, yielding more stable machining and lower scrap rates on complex turning tasks.

System compatibility and economical indexing

Being part of the ISO turning insert series, compatibility with a given holder depends on form, relief angle, tolerance class, fastening, size and thickness. The insert’s 6.35 mm thickness and 19 mm inscribed circle match many standard CNMG holders, while the double-sided design allows indexing to a fresh edge, reducing tooling costs per component. Selecting the correct chipbreaker and the AH6235 grade for the specific alloy and machining stability produces a clear cost‑benefit through longer runtimes and fewer interruptions.

Practical handling, setup and expected benefits

The 1.6 mm corner radius contributes to a robust cutting edge for heavier engagement, improving resistance to chipping on interrupted surfaces. The PVD coating supports consistent performance at elevated temperatures typical of stainless turning, while the cemented carbide substrate maintains edge strength. For workshop practice: verify holder compatibility by checking insert form, thickness and fastening method; choose feed and depth to match the stability of the setup. These measures help to achieve dependable surface quality and reproducible results with minimal rework.

FAQ

What materials is this insert suited for?
The CNMG190616 AH6235 Tungaloy insert is formulated for machining rostfreiem Stahl and other alloys where a tougher grade is required; the AH6235 grade performs well in interrupted cuts and difficult-to-machine stainless materials.

How does the chipbreaker design affect performance?
The double-sided chipbreaker on this Tungaloy turning insert ensures consistent chip control and allows indexing to a fresh cutting edge, which supports process stability and reduces the need for frequent tool changes.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, relief angle, tolerance class, fastening, size and thickness; the CNMG190616 form and 6.35 mm thickness match standard CNMG holders when the clamping and tolerance class are correct.

Is the insert coated and what benefit does the coating bring?
Yes — the insert features a PVD-coated cemented carbide substrate; the coating improves wear resistance, reduces built-up edge on stainless materials and extends tool life under typical turning temperatures.

What does the 1.6 mm corner radius mean for machining?
A 1.6 mm corner radius provides a robust cutting edge that tolerates heavier engagement and intermittent cuts, reducing chipping risk and contributing to a reproducible surface finish with improved part quality.
