TCMT 16T308 T9225 turning insert — Tungaloy

A TCMT 16T308 T9225 ISO triangular turning insert engineered for dependable medium-to-heavy steel turning, suitable for a wide range of external and internal turning operations.

• CVD-coated carbide T9225
• Universal grade for medium–heavy steel
• Triangular ISO insert, 0.8 mm corner radius
• Secure clamping: cylindrical hole + countersink

Consistent cutting performance where stability matters

The CVD-coated T9225 grade delivers a balanced combination of wear resistance and toughness, engineered for medium-to-heavy steel applications where cutting conditions can change or interruptions occur. The CVD coating increases resistance to abrasive wear and reduces built-up edge, leading to more consistent part quality and fewer unplanned tool changes. By choosing a universal, tougher grade, process planners gain a predictable compromise between tool life and cutting rates, reducing scrap and improving overall productivity in batch and single-piece production.

Geometry that promotes repeatability and secure clamping

The insert’s triangular ISO form with an included angle of 60°, a 0.8 mm corner radius, and a 7° relief angle is designed for stable engagement and versatile profile control. The cylindrical hole with a one-sided countersink (40°–60°) provides positive location and clamp seating, which simplifies mounting in compatible holders and helps maintain position tolerances during interrupted cuts. The plate thickness of 3.97 mm and the 16 mm size contribute to the insert’s rigidity; compatibility with a holder depends on form, clearance angle, tolerance class, clamping method, size and thickness, so matching the insert to the correct toolholder ensures the intended performance.

Simplified process integration and predictable tool life

Integrating this indexable insert into an ISO-based system is straightforward: the typical assembly comprises the ISO insert, an appropriate external holder or boring bar, a shim/clamping kit and replacement screws. The robust chip control provided by the single-sided chipbreaker, together with the grade’s stable chip formation, helps reduce cycle interruptions and eases swarf handling. For production environments seeking economical machining with consistent surface finish, the insert’s design reduces downtimes and facilitates faster tool-change cycles. Select the chipbreaker and grade to match workpiece material, machining method and machine stability for the best balance of performance and cost-efficiency.

FAQ

What materials is this insert suited for?
The Tungaloy TCMT 16T308 T9225 insert is intended primarily for medium-to-heavy steel machining and offers robust performance where variable engagement or light interruptions occur.

How does the hole and countersink affect clamping?
The cylindrical hole with a one-sided countersink provides positive seating and improved clamp alignment, helping the insert to remain secure under higher cutting forces and during interrupted cuts.

Can this insert be used for internal turning?
Yes, the geometry and grade of the insert are suitable for both external and internal turning; ensure the correct holder and stability for the intended internal application.

What does the 0.8 mm corner radius mean for surface finish?
A 0.8 mm corner radius balances strength at the cutting edge with achievable surface finish; it helps to distribute cutting forces and can improve tool life on moderate-to-heavy cuts.

Is the grade suitable for interrupted cuts?
The T9225 grade is a tougher, universal choice designed to cope with changing cutting conditions and lightly interrupted cuts while maintaining wear resistance.
