TCMT 16T308 T9215 indexable turning insert by Tungaloy — CVD-coated cemented carbide

TCMT 16T308 T9215 is an ISO-standard indexable insert engineered for external and internal turning in medium-strength steels, offering a balance of wear resistance and resistance to chipping.

• CVD-coated carbide grade T9215
• Designed for medium steel turning
• 60° triangular insert form
• 0.8 mm corner radius, 7° clearance

Proven productivity for medium-steel machining

The CVD-coated T9215 cutting grade is formulated to combine wear resistance with sufficient toughness for productive turning of medium steels. This combination reduces flank wear under sustained cutting conditions and helps avoid premature breakouts during light interruptions. For workshops prioritising throughput, the result is a more predictable tool life and fewer unscheduled index changes, which supports steady operation and lower process variability.

ISO compatibility and secure clamping reduce changeover time

As an ISO-normed triangular insert, the geometry, 7° clearance, tolerance class, attachment and thickness determine holder compatibility. The TCMT form with a cylindrical hole and single-sided countersink (40°–60°) ensures positive seating in compatible holders and stable clamping under radial loads. When used with an appropriate external holder, shim and clamp set, the modular system enables quick indexing and straightforward replacement of worn cutting edges, decreasing machine downtime and improving shop-floor efficiency.

Geometry that balances strength and surface quality

The 60° triangle form provides three indexing positions per insert while the 0.8 mm corner radius offers a compromise between edge strength and surface finish. A small radius improves edge stability and is better for interrupted cuts or heavier depths of cut, while still maintaining acceptable surface quality. Selecting the correct radius and chipbreaker for the workpiece and process stability translates directly into fewer rejects and more consistent part tolerances.

Material and coating: why the specification matters

Constructed from cemented carbide and finished with a CVD coating, the insert resists abrasive and adhesive wear at elevated temperatures common in medium-speed turning. Cemented carbide provides the substrate toughness required for impact resistance, while the CVD layer improves thermal stability and oxidation resistance. For production environments aiming to raise material removal rates without compromising edge life, this combination offers a reliable route to higher productivity.

FAQ

What materials is this insert best suited for?
The TCMT 16T308 T9215 insert is optimised for medium steel machining; the T9215 grade combines wear resistance and toughness for continuous to lightly interrupted cuts in such materials.

How does the TCMT geometry affect holder compatibility?
Compatibility depends on insert form, 7° clearance, tolerance class, attachment and thickness; matching the TCMT form and ISO 16T308 dimensions ensures correct seating in compatible holders.

Does the insert provide easy indexing?
Yes, the triangular form offers three usable cutting edges; the standard hole and countersink arrangement supports secure clamping and straightforward indexing.

What are the advantages of the CVD coating?
The CVD-coated surface improves thermal stability and abrasive wear resistance, extending edge life under the temperatures and speeds typical of medium-steel turning.

Is this insert suitable for interrupted cuts?
The cemented carbide substrate and the T9215 grade provide enhanced fracture resistance, making the insert suitable for continuous to light interrupted machining; for heavy interruption further assessment is recommended.
