TNMG 160408 AH6235 Tungaloy insert for Turning — PVD-coated, 0.8 mm corner radius, 60° geometry

TNMG160408 AH6235 Tungaloy-Wendeplatte gives a compact, ISO-standard solution for general external and internal turning applications where resistance to chipping and process stability are essential

• PVD-coated carbide for stainless steels
• Double-sided chipbreaker for chip control
• ISO TNMG 160408 triangular insert
• Cylindrical hole for secure clamping

Consistent performance where chipping risk is high

The PVD-coated carbide grade AH6235 delivers a tougher substrate and a wear-resistant surface layer, designed specifically for stainless steels and operations with interrupted cutting. This composition improves resistance to edge fracture and reduces unscheduled insert changes. The result is a more predictable machining process and a steadier surface finish during both roughing and semi-finishing passes. By favouring toughness over purely abrasive wear resistance, the grade extends useful edge life under variable cutting conditions.

Secure seating and standardised fit ensure quick changeovers

The triangular insert form with a cylindrical locating hole and standard ISO dimensions provides straightforward compatibility with common external holders and boring bars. Retention depends on matching the holder geometry, free clearance and tolerance class; when these align, the insert seats reliably and repeatably. The ISO TNMG 160408 form factor simplifies tool inventory and reduces setup time, enabling rapid indexing and minimal downtime during multi-shift production.

Geometry tuned for chip control and surface integrity

A 0.8 mm corner radius combined with a double-sided chipbreaker balances edge strength and cutting forces to maintain a clean chip flow and improved surface finish. The 60° included angle supports helpful cutting-edge strength in interrupted cuts while limiting cutting edge overhang. This geometry is particularly useful for components requiring consistent finish with intermittent features, where uncontrolled chips or edge breakout would otherwise compromise dimensional accuracy.

Practical handling, stiffness and economical use

With a 4.76 mm thickness and 16 mm size, the insert offers sufficient rigidity for stable turning without unnecessary bulk. Being double-sided and indexable, it allows multiple fresh cutting edges per insert, reducing tooling expenditure and inventory turnover. The combination of grade, geometry and standardisation makes this insert a practical choice for shops aiming for efficient, reproducible turning processes while keeping changeover and stocking requirements manageable.

FAQ

Is this insert suitable for machining stainless steels?
The TNMG160408 AH6235 insert is specified for stainless steels; the AH6235 PVD-coated carbide provides improved toughness to resist edge breakout during interrupted cuts and variable stainless steel alloys.

Which toolholders are compatible with this TNMG form?
Compatibility depends on standard ISO TNMG geometry and the holder's seat form, free clearance and tolerance class; when the holder matches ISO TNMG 160408 dimensions and clamping style, the insert seats securely for repeatable performance.

What advantages does the AH6235 grade bring compared with harder coatings?
AH6235 is a PVD-coated, tougher carbide grade optimised to reduce chipping risk in stainless steels and interrupted cutting. The grade trades some abrasive wear hardness for edge toughness, improving process reliability under unstable cutting conditions.

How does the 0.8 mm corner radius affect machining results?
A 0.8 mm corner radius increases edge strength and smooths surface finish compared with smaller radii; it is a compromise between robustness and achievable form detail, making it suitable for general-purpose finishing and semi-finishing in turning.
