TCMT 16T308 T9225 Turning insert — Tungaloy, CVD-coated carbide, 60°

TCMT16T308 T9225 is an ISO-standard triangular indexable insert designed for medium to heavy turning applications where intermittent cuts and variable engagement demand toughness and reliable performance

• CVD-coated carbide grade T9225
• Robust universal grade for medium/heavy steel
• Triangular ISO TCMT 16T308, 60° included angle
• 0.8 mm corner radius with one-sided chipbreaker

Consistent cutting performance for demanding turning tasks

The CVD-coated carbide construction with the T9225 grade delivers a balance of wear resistance and toughness tailored for medium to heavy steel machining. This combination reduces flank wear while maintaining edge strength under interrupted cuts, which helps prolong tool life and reduce unplanned changeovers. The insert’s one-sided chipbreaker promotes controlled chip formation, improving surface finish and reducing the risk of built-up edge during variable cutting conditions. For manufacturers seeking process stability, the insert supports reliable cycle times and predictable tool-wear behaviour.

Secure fit and ISO compatibility for flexible tool management

Designed to the ISO geometry TCMT16T308, the insert fits standard triangular holders with a 60° included angle; compatibility depends on form, relief angle, tolerance class, fastening, size and thickness. The insert’s 7° relief and 3.97 mm thickness provide the mechanical support required for stable clamping, while the cylindrical hole with single-side countersink (40°–60°) ensures repeatable locating and torque transmission for secure seating. This standardisation simplifies inventory and tooling logistics and allows straightforward replacement in existing toolholders.

Practical benefits and recommended applications

With a 0.8 mm corner radius and the robust T9225 grade, the insert is particularly suitable for external and internal turning of steel where occasional interruptions or varied engagement occur. The carbide substrate and coating combination supports higher cutting speeds than uncoated grades and maintains edge integrity under moderate cutting forces, making it a cost-effective solution for batch production and repair shops aiming for a reliable balance between tool life and productivity. For complex setups, the insert’s geometry reduces the need for frequent tool changes, supporting smoother production flow and fewer stoppages.

FAQ

What materials is this insert best suited for?
The TCMT16T308 T9225 insert is optimised for the machining of steel; the T9225 grade provides toughness for medium to heavy steel turning and intermittent cuts.

Which holders are compatible with this ISO insert?
Compatibility is determined by holder form, relief angle, tolerance class, fastening method, size and thickness; the insert follows the ISO TCMT 16T308 geometry for triangular holders.

How does the chipbreaker influence machining?
The one-sided chipbreaker on this insert promotes controlled chip formation and evacuation, improving surface finish and reducing built-up edge during turning operations.

What are the key dimensions to check before ordering?
Verify the insert thickness (3.97 mm), corner radius (0.8 mm), relief angle (7°) and the ISO designation TCMT16T308 to ensure correct fit and performance.

Is the insert suitable for interrupted cuts?
Yes, the T9225 grade and carbide substrate are selected to cope with variable engagement and lightly interrupted cuts while maintaining edge stability.
