TNMG220408 AH6235 ISO turning insert — PVD-coated carbide, 60° triangle, Tungaloy

The TNMG220408 AH6235 is an ISO-standard turning insert designed for external and internal turning, optimised for stainless steels and applications with increased chipping risk.

• PVD-coated carbide grade AH6235
• 60° triangular geometry, 0.8 mm radius
• Suitable for stainless steels & interrupted cuts
• Double-sided chipbreaker for reliable chip control

Durable grade and coating for challenging stainless-steel work

The combination of a PVD-coated finish and a tougher carbide AH6235 grade delivers improved resistance against thermal and mechanical wear while maintaining toughness where material adhesions occur. This specification is particularly effective when machining stainless steels or when the cut is interrupted and the risk of edge breakouts is elevated. By using a tougher grade, the insert tolerates edge shock better, reducing unexpected tool changes and increasing process stability.

Predictable geometry and ISO compatibility for simple tool selection

Built to an ISO-standard form, the insert’s 60° triangular shape and clear dimensional data (inscribed circle 22 mm, 0.8 mm nose radius, 4.76 mm thickness) support straightforward selection of matching holders. Compatibility with a chosen toolholder depends on the insert form, clearance angle, tolerance class, attachment method, size and thickness; this standardisation ensures reproducible clamping and repeatable results across setups. The 0° clearance angle specification and cylindrical hole are noted for correct seating and secure fastening.

Chip control and economical indexing for steady productivity

A double-sided chipbreaker offers reliable chip formation and evacuation during turning, which helps maintain surface quality and reduces cycle-time interruptions. The reversible design enables multiple usable cutting edges per insert, enhancing cost-efficiency in series production. For interrupted cuts or unstable setups, the tougher grade mitigates edge chipping, while the chipbreaker geometry promotes consistent swarf behaviour and safer machining conditions.
