TCMT16T304 T9215 Tungaloy turning insert — triangular 60° geometry, 0.4 mm radius

TCMT16T304 T9215 is an ISO‑standard triangular indexable insert designed for productive turning in medium steel applications

• CVD‑coated carbide grade T9215
• Triangle 60° geometry, 0.4 mm radius
• Designed for medium steel machining
• Cylindrical hole with single‑side countersink (40°–60°)

High productivity for medium‑steel turning

The CVD‑coated carbide grade T9215 is engineered to combine enhanced wear resistance with reliable fracture toughness, making it a pragmatic choice for continuous and lightly interrupted cuts in medium steel. This balance reduces the frequency of tool changes and supports stable chip formation, which directly improves process efficiency and component consistency. For contract machine shops and production lines aiming for high throughput, this grade delivers repeatable performance and a measurable effect on machining uptime.

Geometry that secures consistent surface quality

The triangular 60° geometry with a 0.4 mm corner radius gives a strong cutting edge and predictable engagement with the workpiece. The one‑side chipbreaker is tailored to evacuate swarf effectively in standard turning conditions, lowering the risk of workpiece damage and reducing secondary operations. As the insert is ISO‑compliant, selection of a matching external holder or boring bar is straightforward when the form, clearance angle, tolerance class, fastening and thickness are checked, ensuring interchangeability across established tool systems.

Practical dimensions and simple integration

With a nominal size of 16 and a plate thickness of 3.97 mm, the insert fits common ISO toolholders specified for TCMT‑style plates. The presence of a cylindrical hole with a single‑side countersink (40°–60°) facilitates secure mounting and repeatable seat positioning, which shortens set‑up times and reduces variability between insert changes. The mechanical data support fast replacement cycles and predictable clamping torque requirements, helping keep changeover intervals short and process flow steady.

Why this grade pays off in production

Choosing a purpose‑matched cutting grade reduces overall machining cost by extending tool life and keeping component tolerances within target across production runs. The combination of T9215 performance characteristics and the robust triangular form provides a cost‑effective route to higher machine utilisation. For operations focused on reproducibility and stable surface finish, the insert’s construction and geometry represent a reliable investment that supports sustained productivity and fewer unscheduled stops.

FAQ

Which materials is this insert best suited for?
The TCMT16T304 T9215 insert is primarily specified for medium steel machining, where its CVD‑coated carbide composition offers an appropriate balance between wear resistance and toughness.

What is the corner radius and why does it matter?
The insert features a 0.4 mm corner radius, which helps to produce a durable cutting edge and supports consistent surface finish while limiting cutting forces for many turning operations.

How is compatibility with toolholders ensured?
Compatibility depends on the insert form, clearance angle, tolerance class, fastening method, size and thickness; the TCMT16T304 is ISO‑compliant, so matching ISO TCMT external holders or boring bars is customary.

What does the T9215 grade indicate?
T9215 denotes a CVD‑coated carbide grade optimised for medium‑steel applications, offering a compromise between wear resistance and fracture toughness that favours productivity in continuous to lightly interrupted cuts.

Does the insert require a specific mounting screw or clamping set?
The insert uses a central hole with a cylindrical recess and a single‑side countersink; secure clamping requires the appropriate seat and screw as specified by the holder manufacturer and the ISO style of the insert
