TCMT 16T304 T5115 indexable insert for turning — Tungaloy, CVD-coated carbide, 60° triangle

A TCMT 16T304 T5115 indexable insert engineered for ISO-standard turning, optimised for cast iron with a balanced trade-off between wear resistance and cutting-edge robustness.

• CVD-coated carbide for wear resistance
• Triangle 60° form for versatile turning
• 7° clearance angle for stable cutting
• Central hole with countersink for secure fastening

Consistent machining with a universal CVD grade

Made from CVD-coated carbide in the universal T5115 grade, this insert is designed to provide predictable wear behaviour and reliable cutting-edge stability when machining cast iron. The coating improves resistance to abrasive wear and helps maintain a sharper edge over a longer service life, which reduces the frequency of index changes and lowers overall tooling costs. For production runs where consistency and repeatability matter, the coated substrate offers measurable process stability and a steady surface finish.

ISO compatibility and simple tool-system integration

The insert conforms to ISO specifications for triangular turning plates, so compatibility with holders is determined by form, clearance angle, tolerance class, clamping, size and thickness. The standardised geometry allows straightforward replacement in existing toolholders and reduces set-up time. The design with a central hole and a one-sided countersink (40°–60°) ensures secure fastening, while the 3.97 mm thickness contributes to rigidity under load. When selecting a holder, ensure the clamping and tolerance class match the insert code to guarantee concentricity and repeatable performance.

Application-focused geometry and chip control

The 60° triangular shape with a 0.4 mm corner radius provides a compromise between edge strength and surface finish; the radius offers robustness for interrupted cuts and acceptable part finish for finishing passes. The 7° clearance angle reduces flank rubbing, which helps maintain edge life and lowers cutting forces in typical turning operations. The single-sided chipbreaker is optimised for controlled chip formation when turning cast iron; pairing the grade with a suitable chipbreaker and stable workholding yields improved surface quality and predictable tool life. If further process parameters or alternative chipbreakers are required, technical guidance is available to match insert characteristics to the machining task.

FAQ

What materials is this insert optimised for?
The Tungaloy TCMT 16T304 T5115 insert is a universal grade optimised for machining cast iron, combining CVD-coated carbide properties with edge stability for consistent results.

Can this insert be used for both external and internal turning?
Yes, the ISO 60° triangular form and the specified geometry make the insert suitable for both external and internal turning operations when mounted in the correct ISO-compatible holder.

How does the 0.4 mm corner radius affect performance?
A 0.4 mm corner radius provides improved edge robustness for interrupted cuts while still allowing acceptable surface finish; it balances strength and finish requirements in typical turning tasks.

What should be checked to ensure holder compatibility?
Verify the holder matches the insert's form, clearance angle (7°), tolerance class, clamping method, size (16) and thickness (3.97 mm) to ensure concentricity and secure fastening.

Does the insert come with a specific chipbreaker?
This item features a single-sided chipbreaker optimised for controlled chip formation when turning cast iron, helping to maintain process stability.
