TCMT 16T304 T6215 turning insert by Tungaloy — CVD-coated carbide, 7° relief

A TCMT16T304 T6215 ISO turning insert designed for external and internal turning of stainless steel under stable to lightly interrupted cutting conditions

• CVD-coated carbide grade T6215
• ISO TCMT form, 60° triangular geometry
• 7° relief angle for stable cutting
• 0.4 mm corner radius for controlled finishing

Consistent surface quality through wear-resistant grade and chip control

The combination of a CVD-coated carbide matrix and the T6215 grade delivers wear resistance tailored for stainless steel machining. In practice this means fewer tool changes and a more consistent surface finish across serial production, reducing downstream rework. The insert's single-sided chipbreaker is engineered for controlled chip formation in turning operations, which improves swarf evacuation and reduces the likelihood of built-up edge. For shops seeking reproducible component quality, the insert's wear behaviour translates directly into higher process capability and reduced cycle-time variability.

Secure clamping and accurate geometry for repeatable performance

Built to the ISO TCMT standard with a 60° triangular form, the insert features a cylindrical hole with a one-sided countersink (40°–60°) to ensure stable seating in compatible holders. The 3.97 mm thickness and the 7° relief angle increase rigidity at the cutting edge and reduce chatter in medium-duty turning. The specified compatibility depends on form, relief angle, tolerance class, clamping method, size and thickness; these parameters determine correct pairing with an external or boring-bar holder. The 0.4 mm corner radius provides a controlled transition between roughing and finishing, allowing fine surface results without sacrificing edge strength.

Practical advantages on the shop floor and in production planning

Using an ISO-standard insert simplifies inventory and quick changeover: identical geometry and size mean a broad range of holders can be stocked and fitted with minimal adaptation. The TCMT geometry and the T6215 coating are particularly suited to stable to lightly interrupted cuts, making the insert a pragmatic choice where predictable tool life and uncomplicated chip control are priorities. Assembly into a complete system typically requires a matching external holder or boring bar, a support shim or clamping set and replacement screws; verifying holder compatibility before use avoids installation issues and optimises cutting performance.

FAQ

What materials is this insert suitable for?
The TCMT16T304 T6215 insert is designed primarily for stainless-steel machining; the CVD-coated T6215 grade offers wear resistance suited to stable and lightly interrupted turning.

How does the 0.4 mm corner radius affect the cut?
A 0.4 mm corner radius balances edge strength and surface finish, giving controlled cutting geometry that helps to achieve fine surface quality while maintaining robustness in typical turning operations.

What does the hole and countersink specification mean for mounting?
The cylindrical hole with a one-sided countersink (40°–60°) ensures a stable mechanical fit in compatible ISO holders; correct matching of form, size and clamping method is essential for secure seating and repeatable results.

Can this insert be used for internal as well as external turning?
Yes, the ISO TCMT form and the insert dimensions permit both external and internal turning when combined with a suitable boring bar or external holder.

Which grade and coating does the insert use?
The insert uses a T6215 grade with a CVD coating applied to a carbide substrate, optimised for wear resistance in stainless-steel turning.
