TCMT 16T308 T5115 turning insert — Tungaloy, CVD-coated carbide, 60° triangular form

TCMT16T308 T5115 is an ISO-standard indexable insert for general turning, optimised for cast iron machining and compatible with matching ISO holders.

• CVD-coated carbide universal grade
• Triangular 60° geometry for versatile turning
• 0.8 mm corner radius for robust edges
• Cylindrical hole with single-sided countersink

Longer tool life and consistent edge performance for cast iron turning

The TCMT16T308 T5115 indexable insert combines a CVD-coated carbide substrate with a universal grade tuned for cast iron, delivering an advantageous balance between wear resistance and edge strength. The T5115 coating acts as a thermal and chemical barrier, reducing abrasive and notch wear during interrupted cuts. As a result, cycle times are maintained and insert changes become less frequent, which supports higher machine utilisation and lower per-part tooling costs. The trihedral geometry contributes to predictable wear progression and consistent component quality.

Precise clamping and chip control reduce setup variability

Designed to ISO dimensions, the triangular insert features a cylindrical locating hole with single-sided countersink (40°–60°) that ensures secure seat and repeatable clamping in standard holders. The one-sided chipbreaker promotes stable chip formation when turning cast iron, aiding evacuation and minimising re-cutting of chips. Together, these features support repeatable setups and steady cutting forces, which benefits surface finish consistency and reduces the need for frequent adjustments during production runs.

Optimised geometry for demanding external and internal turning

The combination of a 60° triangular form and 0.8 mm corner radius gives the insert versatility across finishing and medium-cutting operations. A moderate corner radius improves edge robustness without compromising accessibility in tight profiles, while the standard relief angle ensures reliable rake and clearance characteristics in most ISO-compatible holders. For applications requiring rapid material removal or improved edge durability, this insert grade offers an efficient compromise between performance and tool life.

Practical selection and system compatibility for workshop use

The insert is supplied to ISO norms and therefore requires selection of a matching external holder or boring bar, plus the correct clamping and screw set. Compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness, so choosing the corresponding holder geometry is essential for achieving the expected performance. Where process stability is critical, pairing the insert with a holder that provides rigid support and correct seat contact will maximise service life and maintain dimensional accuracy on the machined part.

FAQ

What materials is this insert optimised for?
The insert is optimised for cast iron; the T5115 CVD coating provides a balance of wear resistance and edge stability for typical grey and nodular cast irons.

Which holder type is required for correct fitment?
An ISO-compatible triangular insert holder with the correct seat geometry, clamping arrangement and tolerance class is required for reliable use of the TCMT16T308 insert.

How does the T5115 coating benefit production runs?
The T5115 coating reduces abrasive wear and helps maintain edge integrity under thermal load, extending tool life and supporting consistent cycle times in series production.

Is this insert suitable for both external and internal turning?
Yes — the 60° triangular geometry and 0.8 mm corner radius make the insert suitable for a range of external and internal turning tasks where clearance and edge strength are needed.

What is the manufacturer SKU for ordering and reference?
Reference SKU 6864787-Tungaloy or manufacturer SKU TUN6864787 when specifying the insert for procurement or tool preparation.
