TNMG 220408 AH6235 TNMG Turning Insert by Tungaloy — PVD-coated, 0.8 mm corner radius for turning

TNMG220408 AH6235 Tungaloy-Wendeplatte is an ISO‑standard triangular insert developed for external and internal turning, offering a tough, PVD‑coated carbide grade for challenging rostfreier Stahl applications.

• TNMG220408 triangular insert, 22 mm size
• PVD-coated AH6235 grade for rostfreier Stahl
• Double-sided insert with 0.8 mm corner radius
• Cylindrical-hole design, 4.76 mm thickness

Increased tool life through a tough PVD coating

The AH6235 grade is a PVD-coated carbide designed for higher toughness, which reduces chipping and increases durability in interrupted cutting and applications with higher breakout risk. The coating improves wear resistance at elevated temperatures while the substrate delivers the necessary fracture resistance; together these properties extend time between index changes and reduce tool consumption. Compatibility with ISO holders is defined by insert form, clearance angle (0°), tolerance class, attachment method, dimension and thickness, enabling straightforward integration into existing turning systems.

Consistent cutting performance and economical machining

The triangular, ISO TNMG220408 geometry supplies three indexing positions per insert and a secure clamping location via a cylindrical hole, making it economical for batch and single‑piece flows. The 0.8 mm corner radius balances edge strength and surface finish, supporting medium to heavy light‑cut turning where edge robustness matters. The double-sided chipbreaker design aids chip control in both external and internal turning operations, lowering cycle times and improving process reliability when machining rostfreier Stahl and similar materials.

Simple integration into the machining system and practical benefits

As part of an ISO insert system, the recommended setup comprises the indexable insert, a matching external holder or boring bar, a shim/clamping set and replacement screws to maintain clamping integrity. The plate thickness of 4.76 mm and a 22 mm seat size ensure rigidity in many standard holders, while the 60° included angle of the triangular shape supports defined engagement characteristics. Selecting the appropriate chipbreaker and grade for the workpiece material and machine stability converts the insert’s technical specifications into tangible productivity gains and predictable tool life.
