TPMT16T308-PSS AH6225 TPMT 16T308 AH6225 ISO turning insert for turning — Tungaloy, PVD-coated carbide, 0.8 mm

The TPMT16T308-PSS AH6225 is an ISO triangular turning insert engineered for external and internal turning operations, offering a sharp yet robust edge for medium machining and changing conditions.

• ISO triangular form TPMT for secure clamping
• PVD-coated AH6225 tuned for rostfreie Stähle
• 0.8 mm corner radius for reliable edge strength
• Cylindrical hole with single-sided countersink for stable fixing

Consistent cutting performance in medium turning

The triangular insert geometry provides predictable cutting behaviour, while the PVD-coated carbide composition combines hardness with toughness for repeatable results. The specified grade, AH6225, is optimised for rostfreie Stähle and designed to maintain a sharp, stable cutting edge during medium-duty operations and when conditions vary. This leads to fewer insert changes, reduced machine downtime and a more consistent surface finish on workpieces where process stability matters.

Precision geometry and secure clamping for reliable results

With the ISO TPMT form and a cylindrical hole plus single-sided countersink (40°–60°), the insert offers secure seating and accurate location in compatible holders. The 11° relief angle and a corner radius of 0.8 mm balance edge strength and cutting clearance, enabling controlled chip formation with the PSS chipbreaker and contributing to predictable tool life. These geometric choices simplify setup decisions: select the holder matching form, size and thickness and benefit from stable cutting forces and repeatable positioning.

Practical handling and application benefits for workshops

The insert’s 16 mm size and 3.97 mm thickness make it suitable for a wide range of standard external and internal turning holders that accept ISO TPMT plates. The PVD coating improves wear resistance under variable conditions, permitting higher productivity while maintaining surface quality. For production environments seeking steady throughput, the combination of ISO conformity, reliable chip control and a universal carbide grade supports efficient tool management and quicker changeovers.

FAQ

What materials is this insert suitable for?
The AH6225 grade and PVD coating make the insert particularly suitable for rostfreie Stähle and general turning tasks where a balance of edge sharpness and stability is required.

Which holders are compatible with this insert?
Compatibility depends on insert form, relief angle, tolerance class, fastening method, size and thickness; the TPMT geometry and the cylindrical hole with countersink are matched to standard ISO TPMT holders.

How does the PSS chipbreaker affect machining?
The PSS chipbreaker promotes controlled chip formation for medium cutting depths, improving chip evacuation and contributing to consistent surface quality.

What does the 0.8 mm corner radius mean for edge life and finish?
A 0.8 mm corner radius enhances edge strength compared with smaller radii while still allowing good surface finish; it provides a compromise between robustness and fine finish on rostfreie Stähle.

Is this insert suitable for both external and internal turning?
Yes, the insert is specified for both external and internal turning when used with appropriate holders and tool setups.
