CNMG 120404 AH6235 Tungaloy — Turning indexable insert, PVD-coated carbide

The CNMG120404 AH6235 Tungaloy insert is an ISO-standard rhombic turning insert designed for external and internal turning, optimised for stainless steels and interrupted cuts.

• PVD-coated carbide for improved edge life
• Designed for interrupted cutting and chipping risk
• ISO CNMG form with 80° geometry
• Cylindrical hole and 0.4 mm nose radius

Predictable edge stability for demanding stainless-steel work

The AH6235 grade is a PVD-coated carbide developed to combine toughness with wear resistance, making it suitable for machining stainless steels and operations with frequent interruptions. The coating improves resistance against adhesive wear and helps maintain a stable cutting edge under variable engagement conditions. For production contexts where unexpected edge failure would cause downtime, this grade reduces the risk of chipping while maintaining acceptable flank wear rates.

ISO compatibility that simplifies tool management

The insert follows the ISO CNMG120404 designation and a standard rhombic 80° geometry, which ensures compatibility with commonly available CNMG holders when form, clearance angle, tolerance class, attachment and thickness are matched. The cylindrical hole and 4.76 mm thickness provide secure clamping; the 0.4 mm nose radius offers a compromise between surface finish and edge strength. This standardisation supports repeatable set-ups and faster indexable insert changes in routine production.

Efficient chip control and process economy

The double-sided chipbreaker layout, combined with the AH6235 substrate, supports stable chip formation in interrupted cuts and when machining materials prone to work hardening. The result is fewer unplanned tool changes and more predictable cycle times. In sturdy rigs and modest depths of cut, the insert’s toughness helps extend service intervals, contributing to lower tooling costs per component and improved overall process efficiency.

Selection and practical application guidance

Select the chipbreaker and cutting parameters in line with the component material, machining stability and surface-quality targets. The insert is intended for both external and internal turning; for high-stress interruptions or unstable set-ups the tougher grade improves resistance to edge breakage.
