TCMT 16T304 AH6225 – Triangular ISO turning insert for medium-duty rostfreier Stahl machining by Tungaloy

A TCMT 16T304 AH6225 insert for ISO-compliant external and internal turning, offering a 60° geometry and a PVD-coated carbide grade tuned to deliver a sharp yet robust cutting edge under variable conditions

• PVD-coated carbide grade AH6225
• ISO triangular 60° geometry, 16 mm size
• 0.4 mm corner radius for precise profiles
• Cylindrical hole with 40°–60° countersink

Consistent metal removal with reduced wear

The combination of the AH6225 grade and a PVD-coated carbide substrate provides a balance between edge sharpness and wear resistance, making the insert especially effective for medium cutting depths in rostfreier Stahl. The coating reduces thermal and abrasive wear, which translates into more consistent tool life and fewer interruptions for index changes. With a 0.4 mm corner radius, the geometry supports accurate profile reproduction while maintaining sufficient edge strength for intermittent cuts; the one-sided chipbreaker enhances chip formation and evacuation, improving process stability and surface finish.

Secure fit and repeatable clamping for predictable results

Designed as an ISO-standard triangular insert, the item matches holders when form, clearance, tolerance class, fastening, size and thickness align. The 60° included angle and 7° clearance angle ensure compatibility with a wide range of external and internal turning holders, while the cylindrical hole with single-sided countersink (40°–60°) enables stable mechanical clamping and straightforward index changes. A plate thickness of 3.97 mm and a nominal size of 16 mm support rigidity in most workshop setups, reducing vibration and promoting repeatable cutting conditions across batches.

Flexible choice for practical workshop applications

For everyday turning tasks, the insert’s combination of PVD coating, carbide core and a dedicated chipbreaker makes it a versatile option for shops seeking a single grade that covers several rostfreier Stahl applications. Select the chipbreaker and insert geometry according to workpiece material, machining strategy and machine stability to maximise productivity; in mixed-production environments, this approach shortens setup times and simplifies tooling inventories. The solution supports an efficient workflow by offering durable cutting performance with minimal compromise on surface quality.

FAQ

Which materials is this insert suited for?
The TCMT 16T304 AH6225 insert is formulated for machining rostfreier Stahl and performs well across a range of austenitic and similar alloys when used under recommended parameters.

What is the effect of the 0.4 mm corner radius?
A 0.4 mm corner radius balances profile accuracy and edge strength, allowing the insert to produce defined contours while resisting premature chipping during medium-duty turning.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, clearance, tolerance class, fastening, size and thickness; the ISO 60° triangular geometry and the cylindrical hole with countersink ensure fitment with standard ISO triangular turning holders designed for 16 mm inserts.

What advantages does the AH6225 PVD coating provide?
The AH6225 grade with a PVD coating enhances wear resistance and thermal stability, extending usable edge life and improving consistency in surface finish during medium cutting operations.
