TNMG160416 AH6225 Tungaloy turning indexable insert — triangular ISO insert for turning

TNMG160416 AH6225 is an ISO‑standard triangular indexable insert designed for turning applications, optimised for medium machining of stainless steels with a sharp yet stable cutting edge.

• ISO-standard triangular insert TNMG160416
• PVD-coated carbide grade AH6225 for stainless steel
• Sharp yet stable cutting edge for medium cuts
• Double-sided, cylindrical hole, 4.76 mm plate thickness

Consistent performance for turning stainless steels

The PVD‑coated AH6225 grade combines a hard substrate with a wear-resistant coating to deliver reliable edge stability in variable conditions. This composition is particularly suited to machining stainless steels, where surface quality and predictable tool life are decisive for production flow. The combination of a controlled coating and a carbide body reduces flank wear and helps maintain cutting geometry, which translates into fewer interruptions and more uniform part quality during medium cutting operations.

Geometry and what it means for machining

The triangular insert features a 1.6 mm nose radius and a 60° included angle, offering a balanced compromise between strength and profile control. A 1.6 mm radius provides improved tool strength over smaller radii while still allowing satisfactory surface finish on turned profiles. The specified 0° rake angle supports stable cutting in interrupted cuts and variable feeds, making the insert a dependable choice where mixed conditions occur. These geometric details allow process planners to predict cutting forces and select suitable holders and feeds for consistent cycle times.

System compatibility and secure clamping

As an ISO‑standard insert, compatibility with holders is determined by form, clearance angle, tolerance class, fastening method, size and thickness. The design includes a cylindrical central hole for positive locating and a double‑sided configuration that provides multiple indexable cutting edges, improving economy per insert. For a complete system, pair the insert with a matching external holder or boring bar, and use an appropriate clamping plate and replacement screws to ensure repeatable seat stability and vibration resistance during operation.

Practical handling and machining advice

The insert's 4.76 mm plate thickness and triangular shape provide a robust platform for medium turning. Being double‑sided extends usable life and reduces tooling costs per edge. When setting up, consider moderate cutting speeds and feeds aligned with the AH6225 recommendations for stainless steels, and use rigid workholding to benefit from the insert's stable chip formation. Where surface finish is critical, minor adjustments to feed and coolant strategy can enhance results without compromising the insert's service life.
