TNMG160404 AH6225 ISO indexable turning insert — PVD-coated carbide for turning | Tungaloy

TNMG160404 AH6225 is an ISO-format indexable turning insert designed for external and internal turning of stainless steels, combining a sharp yet stable cutting edge with a double-sided chipbreaker for reliable medium machining.

• PVD-coated carbide grade AH6225
• Double-sided chipbreaker for cost-effective indexing
• ISO-standard TNMG160404 for wide holder compatibility
• Triangular form with cylindrical hole for secure clamping

Consistent performance on rostfreiem steels through PVD-coated carbide

The PVD-coated carbide grade AH6225 is formulated for turning stainless steels where a balance of edge sharpness and wear resistance is required. The coating reduces flank wear and heat-induced degradation, which means more consistent cutting performance under variable conditions. For medium metal removal rates the result is a predictable tool life and a stable surface finish; machinists benefit from fewer interruptions and more uniform batch results. The combination of a sharp and stable cutting edge with PVD protection supports both efficiency and repeatability on demanding rostfreiem materials.

ISO-format design for straightforward integration and secure clamping

As an ISO-standard TNMG insert, this item fits established indexable-holder systems provided the holder matches form, clearance angle, tolerance class, mounting and size. The insert is triangular with a cylindrical hole, facilitating secure clamping and straightforward orientation. Its double-sided chipbreaker allows reversing to use the second cutting edge, improving cost-effectiveness per index. Important geometric data — such as the 0.4 mm corner radius and 4.76 mm thickness — determine cutting strength and component geometry, so matching these dimensions to the toolholder and workholding setup ensures optimal stability and surface integrity in turning operations.

Practical guidance for machining and tool selection

For external and internal turning applications, select the chipbreaker variant and cutting parameters that match workpiece rigidity and feed rates; the insert’s 0.4 mm radius favours a mix of edge strength and fine finish, while the 60° included angle aligns with many triangular holder geometries. Because compatibility depends on form, free angle, tolerance class and mounting details, users benefit from checking holder specifications before assembly. The insert's double-sided nature and ISO conformity support efficient inventory management and predictable changeover intervals, helping to maintain production flow with minimal downtime.

FAQ

What materials is this insert suitable for?
The TNMG160404 AH6225 insert is specified as a universal grade for stainless steels, offering a balance of sharpness and wear resistance for medium turning applications.

How does the double-sided chipbreaker affect cost efficiency?
A double-sided chipbreaker provides two usable cutting edges per index, increasing edge utilisation and lowering cost per index for the TNMG160404 AH6225 insert.

Which holders are compatible with this ISO-format insert?
Compatibility requires matching the holder to the insert form, clearance angle, tolerance class, mounting and size; the ISO-standard designation TNMG160404 supports a wide range of commercial turning holders.

What cutting geometry should be considered for fine surface finish?
The 0.4 mm corner radius and PVD-coated carbide grade AH6225 favour a compromise between edge strength and finish quality; lower feed rates with stable clamping yield improved surface integrity.

Is this insert reversible and indexable?
Yes, the triangular TNMG160404 design with a double-sided chipbreaker is reversible, permitting indexing to the second cutting edge to extend service life.
