TCMT 16T304 T9215 turning insert for turning — Tungaloy

A TCMT16T304 T9215 triangular ISO insert designed for external and internal turning of medium steels, combining a CVD‑coated carbide grade with a secure hole and countersink for reproducible clamping

• CVD-coated carbide grade T9215
• Optimised for medium steel machining
• ISO triangular insert TCMT 16T304
• 0.4 mm corner radius, 7° clearance angle

Consistent tool life for continuous production

The CVD‑coated carbide composition of this grade T9215 offers a combination of wear resistance and fracture toughness, which is particularly valuable when aiming for uninterrupted production runs. For turning tasks on medium steels, the coating increases resistance to abrasive wear while the substrate maintains edge integrity under load. In practice, this means longer intervals between index changes and fewer unplanned tool exchanges, supporting a measurable increase in line utilisation and reduced process variability.

Geometry engineered for repeatable accuracy

The triangular geometry and ISO designation ensure straightforward integration into standard toolholder systems. The 0.4 mm corner radius together with a 7° clearance angle and a 60° wedge angle contribute to a controlled cutting action that balances surface finish and tool strength. The insert is supplied with a cylindrical hole and single‑sided countersink, enabling secure clamping that reduces vibration and improves repeatability. Such mechanical stability translates into more consistent part quality and predictable tool performance.

Practical application and system compatibility

Designed for both external and internal turning, the insert performs best in continuous to slightly interrupted cuts, where the combination of chip control and edge robustness yields high productivity and improved surface finish. Selection of the correct chipbreaker and grade pairing remains critical: match the chipformer to the workpiece material and the machine–workpiece setup for optimal results. Remember that the complete system comprises the insert, a compatible holder, a shim or clamping set and the correct fastening screws — together these elements determine the achievable feed rates, cutting depths and process stability.

FAQ

Which materials is this insert best suited for?
The TCMT16T304 T9215 insert from Tungaloy is optimised for medium steel machining and delivers reliable wear resistance and edge strength for these materials.

Can this insert handle interrupted cuts?
The insert is recommended for continuous to slightly interrupted cuts; for heavily interrupted conditions a more robust grade or a different chipbreaker may be preferable.

What determines compatibility with toolholders?
Compatibility depends on the insert form, clearance (relief) angle, tolerance class, fastening method, size and thickness — ensure the holder accepts TCMT 16T304 geometry.

How should the chipbreaker be chosen?
Select a chipbreaker matched to workpiece material, machining strategy and machine‑part rigidity; the single‑sided chipbreaker is suitable for the applications described in the product data.

What are the key dimensions to check before ordering?
Verify the 16 mm size, 3.97 mm thickness, 0.4 mm corner radius and the 7° clearance angle against the intended holder and application; SKU 6777780‑Tungaloy identifies this specific item.
