TNMG160412 AH6225 Tungaloy turning insert — PVD-coated carbide, 60° triangular

A TNMG160412 AH6225 ISO triangular turning insert engineered for external and internal turning operations, optimised for medium cutting when machining rostfreier Stahl.

• ISO triangular insert, 60° geometry
• PVD-coated AH6225 for rostfreier Stahl
• 1.2 mm corner radius for a stable cutting edge
• Cylindrical hole for secure clamping

Precision and performance for consistent turning results

The PVD-coated carbide composition (grade AH6225) offers a reliable combination of edge sharpness and wear resistance, designed specifically for machining rostfreier Stahl under varying conditions. The triangular ISO insert geometry with a 60° rake provides good engagement and flexibility for both external and internal turning tasks. With a 1.2 mm corner radius, the insert supports a robust cutting edge that reduces the risk of chipping during interrupted cuts while maintaining acceptable surface finish. This balance of features translates into predictable tool life and fewer unscheduled insert changes, which supports higher overall process efficiency.

Simplified tool changeover and secure clamping for less downtime

Standardised ISO dimensions mean the insert matches holders when form, relief angle, tolerance class, fastening method, size and thickness are aligned; this makes replacement straightforward and reduces setup complexity. The cylindrical hole and double-sided design permit reliable clamping and indexing, letting production teams restore cutting capability quickly without custom fixtures. Using an ISO-standard component also eases inventory management: compatible ISO turning holders, clamps and spare screws form a simple system that supports fast changeovers and reduced machine downtime.

Application guidance for improved productivity and surface quality

For medium-depth turning of rostfreier Stahl, select feed and speed to favour stability: a moderate cutting speed with controlled feed rates preserves the sharp PVD-coated edge while the double-sided chipbreaker promotes predictable chip flow. Where component geometry or machine rigidity is limited, favour a conservative depth of cut and ensure coolant or appropriate lubrication is used to manage temperature. The insert’s properties support improved surface finish when paired with stable setups and suitable holders, so cycle times can be reduced through confidence in repeatable cutting behaviour rather than by increasing risk.

FAQ

What materials is this insert best suited for?
The TNMG160412 AH6225 insert is optimised for machining rostfreier Stahl and performs well in medium cutting operations where a sharp, stable edge is required.

Can the insert be indexed to use both cutting edges?
Yes, the insert is double-sided and can be rotated to present a fresh edge, allowing economical use of both sides before replacement.

Which holders are compatible with this ISO insert?
Compatibility depends on the holder’s form, relief angle, tolerance class, fastening method, size and thickness; standard ISO triangular turning holders with the correct seat and clamping will accept this insert.

Does the PVD coating improve tool life on rostfreier Stahl?
The PVD coating on grade AH6225 enhances wear resistance and helps maintain a sharp cutting edge under varied conditions, contributing to longer, more predictable tool life when machining rostfreier Stahl.

Is this insert suitable for finishing passes?
With appropriate cutting parameters and a stable setup, the insert can achieve good surface quality for finishing; the 1.2 mm corner radius provides a compromise between edge strength and finish capability.
