TNMG 160408 AH6235 turning insert for turning – Tungaloy

TNMG160408 AH6235 is a triangular ISO-standard turning insert designed for external and internal turning where increased chipping resistance is required; suitable for interrupted cuts and rostfreier Stahl applications.

• PVD-coated carbide AH6235 grade
• 60° geometry with 0° clearance angle
• 0.8 mm corner radius for strength
• Double-sided chipbreaker, cylindrical hole

Engineered for consistent edge life and chip control

The PVD-coated carbide composition of this insert provides a balanced combination of wear resistance and toughness. The AH6235 grade is formulated for demanding environments such as rostfreier Stahl and interrupted cuts, reducing the risk of edge breakouts. A 0.8 mm corner radius increases cutting-edge robustness while the 60° geometry delivers good access to profiles and stable engagement in typical turning operations. In practice, this translates into fewer unscheduled indexings and steadier process times on mixed batches and harder-to-machine materials.

Predictable fit and fast indexation improve uptime

Compatibility with tool holders is governed by form, clearance angle, tolerance class, fastening and plate thickness; adherence to the ISO standard ensures predictable interchangeability across compliant systems. The insert’s cylindrical hole and two-sided chipbreaker allow secure clamping and straightforward indexing, so clamping integrity is maintained even under variable cutting forces. Reduced setup complexity and reliable seating lead to measurable productivity gains in serial turning tasks.

Grade selection and machining strategy for rostfreier Stahl

Choosing the right chipbreaker and a tougher grade like AH6235 mitigates chatter and flank chipping when machining rostfreier Stahl or when facing interrupted cuts. The coated carbide surface improves edge life at elevated temperatures, while the double-sided design offers multiple cutting edges per insert to lower tooling cost per part. For finishing passes where surface quality is critical, consider a finer geometry; for roughing and semi-finishing, the toughness and chip control of this insert support higher feed rates with maintained process security. The TNMG160408 AH6235 insert therefore suits production settings that prioritise repeatability and stable material removal.

FAQ

Which materials is this insert best suited for?
The TNMG160408 AH6235 Tungaloy insert is specified for rostfreier Stahl and other materials prone to chipping where a tougher grade and PVD coating improve edge life.

Is the insert coated and what does the coating provide?
Yes, the cutting grade features a PVD coating on a carbide substrate, which enhances wear resistance and thermal stability during typical turning operations.

How does the cylindrical hole affect clamping?
The cylindrical hole allows secure clamping and consistent seating in properly matched holders, supporting stable cutting conditions for the TNMG160408 AH6235 insert.

How many cutting edges are available per insert and how is indexing performed?
The triangular, double-sided design provides multiple usable edges per insert; indexing is carried out by loosening the clamp, reversing or rotating the plate and re-tightening to the prescribed torque.

Can this insert be used for finishing passes?
While AH6235 is optimised for toughness and interrupted cuts, it can be used for semi-finishing; for high-quality finishing on delicate surfaces, a finer geometry or a different grade may be preferable.
