TNMG 160412 AH6235 Tungaloy turning insert — triangular, PVD-coated carbide for turning

The TNMG 160412 AH6235 is an ISO-standard triangular turning insert designed for external and internal turning operations where increased resistance to notch formation and interrupted cuts is required.

• PVD-coated carbide for stainless steels
• 60° triangular geometry for stable cutting
• Double-sided chipbreaker for consistent chips
• Cylindrical hole for secure clamping

High process reliability for stainless-steel turning

The PVD-coated carbide grade AH6235 delivers a tough cutting edge optimised for machining stainless steels and applications with intermittent cutting. The coating enhances adhesion and thermal stability while the substrate provides fracture resistance, which together reduce the risk of edge breakouts during unstable cuts. This results in a more consistent tool life and fewer unscheduled insert changes, supporting a predictable production flow and improved machining uptime.

Stable geometry that supports precise turning

The triangular 60° geometry and 1.2 mm nose radius offer a balance between good edge strength and dimensional control. The geometry is particularly suitable for applications requiring reliable corner strength and repeatable edge position; the modest nose radius helps maintain surface finish without sacrificing robustness. The insert’s 0° clearance and standardised ISO form ensure compatibility with a wide range of holders, while the cylindrical hole provides secure seating and repeatable clamping.

System compatibility and what to consider when integrating

Compatibility with a turning holder depends on form, clearance angle, tolerance class, fastening method, size and thickness. The insert is intended for use in a complete system comprising an ISO turning insert, a matching external holder or boring bar, a shim/clamp set and replacement screws. Selecting the correct chipbreaker and grade for the workpiece material and machining stability will directly influence chip control and surface quality; here, the double-sided chipbreaker supports reliable chip formation across varied cutting conditions.

Practical benefits when machining interrupted cuts and tough alloys

For interrupted cuts and materials prone to notch wear, the tougher substrate and PVD coating of this grade reduce edge chipping and extend usable life. The insert’s design helps maintain tool performance under fluctuating engagement and impact, giving fewer regrinds and more consistent component tolerances. Where surface finish and process stability matter, this insert provides a pragmatic balance of productivity and edge security.
