• CVD‑coated carbide for robust steel machining
• 0.4 mm corner radius, 7° clearance angle
• Cylindrical hole with single‑side countersink

Consistent metal removal for medium to heavy steel

The CVD‑coated carbide grade T9225 delivers a balanced combination of toughness and wear resistance, optimised for medium to heavy steel operations where varying engagement or light interruptions occur. As an ISO triangular insert, the geometry provides a reliable 60° included angle, offering stable cutting forces and predictable tool life. The 0.4 mm corner radius helps maintain edge strength while allowing acceptable surface finish; the CVD coating reduces flank wear and enhances thermal resistance, which translates into longer tool cycles and fewer interruptions in production. This technical stability supports higher productivity with reproducible results.

Fast integration and secure clamping for efficient shopfloor workflow

Compatibility with toolholders is determined by insert form, clearance, tolerance class, fixing method, size and thickness; this ISO series fits conventional holders and boring bars when those parameters match. The insert’s cylindrical hole with a single‑side countersink (40°–60°) ensures secure seating and straightforward torque control during clamping, while the 3.97 mm plate thickness contributes to rigidity under load. The system approach — insert, matching holder or boring bar, shim/clamp set and spare screws — reduces setup complexity and enables fast, repeatable insert changes, cutting fixture downtime and supporting predictable cycle times.

Reliable chip control and application guidance for operators

A one‑sided chipbreaker geometry is provided to suit a broad range of steel cutting situations; selecting the correct chipformer and grade helps avoid built‑up edge and improves swarf evacuation, which supports process safety and surface quality. The insert is made from carbide and coated for durability, making it a practical choice when robustness is required rather than delicate finishing. For specific machining parameters or to match the chipbreaker with a particular steel grade and machine stability, Metav Werkzeuge can provide application recommendations and cutting data, enabling efficient setup and reduced trial runs.

FAQ

What materials is this insert best suited to machine?
The TCMT16T304 T9225 is optimised for medium to heavy steel machining; the T9225 grade provides toughness for variable engagement and lightly interrupted cuts.

How does the 0.4 mm corner radius affect performance?
A 0.4 mm corner radius increases edge strength compared with smaller radii, improving resistance to chipping while still enabling acceptable surface finish for many turning tasks.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, free angle, tolerance class, fixing method, size and thickness; the insert conforms to ISO dimensions for straightforward matching with compatible external holders or boring bars.

What is the purpose of the cylindrical hole with a countersink?
The cylindrical hole with a single‑side countersink (40°–60°) secures the insert in the pocket and allows reliable clamping torque distribution, improving seating accuracy and repeatability.

Can this insert handle interrupted cuts?
Yes; the CVD‑coated carbide T9225 is specified as a robust universal grade that tolerates varying engagement and light interruptions without rapid edge failure.
