TCMT 16T304 T9215 Tungaloy indexable insert — CVD-coated carbide, 60°

TCMT16T304 is an indexable turning insert developed for medium steel machining, offering a CVD-coated carbide grade for high productivity in continuous to slightly interrupted cuts.

• CVD-coated carbide T9215 for medium steel
• Triangular insert, 60° included angle
• 0.4 mm corner radius for precision finishes
• With hole and countersink for secure clamping

Optimised cutting performance for medium steel

The TCMT16T304 grade combines a CVD-coated surface with a cemented carbide substrate to deliver elevated wear resistance and reliable edge integrity during repetitive turning operations. The T9215 coating is tailored for the machining of medium-strength steel, enabling longer tool life and reduced flank wear under continuous cutting conditions. This technical pairing reduces downtime for insert changes and supports stable cycle times on automated turning centres.

Geometry and compatibility that simplify setup

A triangular shape with a 60° included angle and a 0.4 mm corner radius ensures a balance between cutting strength and surface finish. The insert is manufactured to ISO dimensions and features a central hole with a cylindrical hole plus one-sided countersink (40°–60°) to match common clamping systems. These characteristics make the component compatible across a wide range of external holders and boring bars, streamlining inventory and reducing holder-specific complexity.

Predictable chip control and process stability

The insert is supplied with a single-sided chipbreaker designed to suit the grade and the typical chip forms encountered in steel turning. With the right feed and depth settings the chipbreaker promotes controlled chip formation, aiding coolant access and evacuation. This targeted geometry supports productivity by reducing the likelihood of built-up edge and by maintaining consistent surface quality through extended tool life.

Practical benefits for production workflows

Key operational advantages include easy insert indexing thanks to the triangular form, consistent repeatability from one index to the next, and straightforward spare-part handling due to ISO normalisation. The moderate relief angle (7°) contributes to cutting efficiency while preserving edge robustness during slight interruptions. In practice, these features translate into fewer unscheduled stops and a stable quality level across batches.

Selecting the right parameters for your application

For continuous to lightly interrupted turning of medium steels, choose feed and speed settings that exploit the T9215 grade’s wear resistance without overloading the edge. Lower feeds with moderate depth of cut favour improved surface finish, while higher feeds leverage the grade for faster material removal. When machining more abrasive or heavier-interrupted conditions, consider a different geometry or grade designed for increased toughness.

FAQ

What materials is this insert designed for?
The TCMT16T304 T9215 indexable insert is optimised for medium-strength steel applications, where the T9215 CVD-coated carbide provides a good balance of wear resistance and toughness.

Is the insert compatible with standard ISO turning holders?
Yes, the insert follows ISO dimensions (16T304) and the hole plus countersink design ensures compatibility with common clamping systems for triangular turning inserts.

What is the corner radius and how does it affect finish?
The insert has a 0.4 mm corner radius; this radius supports improved surface finish while maintaining sufficient edge strength for general turning operations.

Can the insert handle interrupted cuts?
The grade and geometry are aimed at continuous to lightly interrupted cuts; for heavy interruptions a tougher geometry or different grade may be advisable.

How many cutting edges are available per insert?
The triangular form offers multiple indexed edges; exact usable edges depend on the chosen orientation and wear limits, providing economical indexable performance.
