TNMG110408 AH6225 Tungaloy turning insert — PVD-coated carbide, 60° triangle

TNMG110408 AH6225 is an ISO‑standard turning insert designed for external and internal turning, optimised for rostfreien Stahl with a balance of sharpness and edge stability

• PVD-coated carbide AH6225
• Universal grade for rostfreien Stahl and mixed conditions
• Triangular form with 60° cutting angle
• 0.8 mm corner radius and double-sided chipbreaker

Reliable performance for rostfreien Stahl in mixed conditions

The PVD‑coated AH6225 grade combines a fine coating with a tough substrate to deliver consistent cutting behaviour when machining rostfreien Stahl. This universal grade is developed to maintain a sharp yet stable cutting edge, reducing the risk of edge breakdown during medium cutting operations and under changing process conditions. The result is improved productivity with fewer insert changes and a more predictable process window.

Geometry and clamping for predictable repeatability

The triangular form and 60° nominal cutting geometry provide a reliable seating and predictable cutting direction, while the insert’s dimensions ensure compatibility with ISO holders when form, relief angle, tolerance class, fastening and thickness match. A 0.8 mm corner radius gives a good compromise between edge strength and surface finish, making the insert suitable for operations that demand repeatable dimensional control and secure clamping.

Chip control that supports surface quality

Equipped with a double-sided chipbreaker, the insert promotes controlled chip formation in a range of cutting conditions. Improved chip control reduces the likelihood of rework and protects the workpiece surface, supporting better first‑pass quality. This focused design helps deliver a smoother finish on rostfreien Stahl components while maintaining efficient material removal.

Durable substrate and coating for longer tool life

Manufactured from cemented carbide and finished with a PVD coating, the insert is engineered for wear resistance and thermal stability during turning. The coating enhances edge adhesion and reduces abrasive wear, which contributes to longer tool life and lower total machining cost per part. For operations where repeatability and uptime are priorities, this grade offers a dependable balance of life and performance.

Application scope and process advice

The insert is intended for external and internal turning in medium machining regimes; selection of the correct chipbreaker and grade should be based on workpiece stability, cutting data and the specific rostfreien Stahl grade being processed. Where vibration is limited and clamping is rigid, the sharpness of the grade improves cutting efficiency; where stability is marginal, larger radii or reduced feeds may extend life.

ISO conformity and system components for easy integration

As an ISO‑standard insert, compatibility with holders is driven by form, relief angle, tolerance class, fastening method, size and thickness. The typical system includes the ISO insert, a matching external holder or boring bar, a shim/clamping set and replacement screws. The 4.76 mm thickness and the option with cylindrical hole support straightforward mounting and secure fixation in most standard toolholders for turning operations.
