TCMT 16T304 T9215 triangular indexable insert for Turning — CVD-coated carbide, 0.4 mm nose radius (Tungaloy)

TCMT16T304 T9215 is an ISO-standard indexable insert for external and internal turning; engineered for productive machining of medium steels with continuous to light interrupted cuts

• CVD-coated carbide for medium steels
• Triangle shape, 16 mm size
• 7° clearance angle for stable cutting
• Single-sided chipbreaker, with hole

High, consistent productivity for medium-steel turning

The TCMT16T304 T9215 indexable insert brings a balance of wear resistance and fracture toughness that suits medium-steel applications. The CVD-coated carbide grade T9215 is formulated to sustain higher cutting rates while preserving edge integrity, so each indexable corner delivers predictable performance. For production environments where cycle time and repeatability matter, this insert enables more parts per shift without compromising surface quality.

Reduced set-up complexity and ISO compatibility

Designed to the ISO plate programme, the triangular insert matches a wide range of ISO holders by form, relief angle, tolerance class, attachment method, size and thickness. The standardised geometry simplifies tool selection and inventory management: one insert shape fits multiple holder types, reducing downtime. The triangular form with a central fastening hole and a cylindrical hole plus single-sided countersink ensures secure clamping and repeatable positioning during index changes.

Improved process stability through geometry and coating

Key geometry features — a 0.4 mm nose radius and 7° clearance angle — combine to produce stable chip formation and robust edge support. The single-sided chipbreaker is optimised for continuous to lightly interrupted cuts, promoting consistent chip evacuation and lowering built-up edge tendencies. The CVD coating contributes to thermal and abrasive resistance, extending tool life and maintaining dimensional accuracy over longer runs.

Practical handling and application guidance

With a plate thickness of 3.97 mm and a 16 mm inscribed circle, this indexable insert is compact yet durable for routine turning tasks. The insert is intended for turning operations where medium steels are the primary workpiece material; selecting the appropriate feed and speed according to the grade’s capability helps to exploit its wear resistance and fracture tolerance. When switching from uncoated or different grades, trial passes at conservative parameters are recommended to establish optimal cutting data.

FAQ

What materials is this insert suitable for?
The Tungaloy TCMT16T304 T9215 insert is intended primarily for medium steels, combining wear resistance and toughness to perform well in those applications.

Can the insert be used for interrupted cuts?
Yes, the CVD-coated grade T9215 and the insert geometry are suitable for continuous to light interrupted cuts, offering improved edge strength for occasional interruptions.

Which holder types fit this insert?
As an ISO-standard triangular insert, it is compatible with ISO external and internal turning holders that accept 16 mm TCMT inserts and the specified thickness and hole style.

How does the 0.4 mm nose radius affect surface finish?
A 0.4 mm nose radius delivers a compromise between strength and finish: it supports moderate feed rates while producing a stable surface quality for typical turning operations.

Is the coating suited to high-speed turning?
The T9215 CVD coating increases thermal and abrasive resistance, allowing elevated cutting speeds for many medium-steel jobs, provided coolant and machining parameters are adjusted accordingly.
