ISO-standard triangular form with 60° angle
Double-sided chipbreaker and central hole

Reliable cutting performance for stainless steels

The insert's PVD-coated hardmetal delivers a sharp and stable cutting edge, optimised for medium cutting conditions and variable workpiece materials. The AH6225 grade is formulated to improve wear resistance and heat management when machining stainless steels, reducing built-up edge and promoting consistent surface finish. This results in fewer interruptions, predictable tool changes and improved process efficiency in serial production.

Predictable fit and geometry for quick integration

Built to the ISO series of indexable turning inserts, the triangular form with a 60° included angle and corner radius 1.6 mm ensures compatibility with a wide range of external holders and boring bars when the matching seat geometry, clearance angle and clamp arrangement are observed. The insert's 0° clearance angle and 4.76 mm thickness contribute to stable contact in the pocket, while the central cylindrical hole provides secure fastening and repeatable positioning for reliable machining cycles.

Reduced changeover and controlled chip formation

Featuring a double-sided chipbreaker and a robust PVD hardmetal substrate, the design supports controlled chip flow during both light and moderate cuts, reducing tool downtime and improving component quality. The indexable design allows multiple indexed edges per insert, lowering per-edge cost and shortening reconditioning intervals. For best results, select the chipbreaker and cutting parameters matched to the workpiece hardness and the intended finishing or semi-finishing operation.

FAQ

What materials is this insert intended for?
The TNMG160416 AH6225 insert is designed primarily for machining stainless steels, with the AH6225 grade offering a balance of edge sharpness and wear resistance for variable conditions.

How does the 1.6 mm corner radius affect machining?
A 1.6 mm corner radius on the TNMG160416 provides improved edge strength and a better surface finish in semi-finishing operations while maintaining adequate profile control for many external and internal turning tasks.

Is the insert compatible with standard ISO holders?
Yes; the TNMG160416 follows ISO indexable insert geometry and fits holders that match the triangular form, thickness and central cylindrical hole configuration.

What fastening method does the insert use?
The insert features a cylindrical hole intended for secure clamping with the appropriate screw, shim or clamp in common ISO-style turning toolholders.

Can this insert be indexed to present a fresh cutting edge?
The TNMG160416 is designed as a double-sided, indexable insert so edges can be rotated or flipped according to the insert and holder combination to extend service life.
