TPMT 16T304 T5115 ISO turning insert — CVD‑coated carbide for cast iron by Tungaloy

TPMT16T304-CM T5115 delivers ISO‑standard performance for external and internal turning, offering a universal grade optimised for cast iron applications.

• ISO‑standard triangular insert
• CVD‑coated carbide grade T5115
• Designed for cast iron machining
• 0.4 mm corner radius, 11° relief

Consistent productivity through balanced wear resistance and edge stability

The CVD‑coated cemented carbide grade T5115 provides a calculated balance between wear resistance and edge stability, which translates into longer effective cutting life and fewer unplanned tool changes. As an ISO‑conforming triangular insert, this plate is intended for routine external and internal turning operations where repeatable dimensional results and steady tool performance are priorities. The universal nature of the grade means it is suitable for a wide range of cast iron variants, reducing inventory complexity while maintaining process reliability.

Secure seating and precise geometry for repeatable results

A geometry that includes a 0.4 mm corner radius, 11° relief angle and a 60° insert angle ensures stable cutting forces and a predictable surface finish. The plate thickness of 3.97 mm and the triangular form combine with a central fixing arrangement — a cylindrical hole with single‑sided countersink (40°–60°) — to provide secure clamping in compatible holders and boring bars. This construction minimizes micro‑movement at the cutting edge and supports consistent chip formation, which is particularly beneficial in high‑volume turning where fixture repeatability affects part conformity.

Practical application guidance and operational benefit

Equipped with the CM chipbreaker, the insert promotes controlled chip flow during cast iron machining and helps to avoid entangling swarf in confined setups. The ISO designation simplifies selection for standard toolholders, while the TPMT16T304-CM T5115 marking aids clear identification in tooling management systems. Choosing this insert can improve overall process efficiency by reducing downtime for tool changes and by delivering a reliable finish on cast iron components, supporting downstream operations and quality control.

FAQ

What materials is this insert recommended for?
The TPMT16T304‑CM T5115 insert is specified primarily for cast iron machining; the CVD‑coated T5115 grade balances wear resistance and edge stability for that material class.

Which holders are compatible with the TPMT16T304‑CM designation?
Compatibility is determined by insert form, relief angle, tolerance class, fixation style, size and thickness; ISO‑standard holders for triangular TPMT inserts accommodate the TPMT16T304‑CM plate when matching parameters are observed.

How does the CM chipbreaker affect performance?
The CM chipbreaker promotes effective chip control in turning cast iron, reducing the risk of long, stringy chips and aiding consistent surface quality with the T5115 grade.

Is this insert suitable for finishing and semi‑finishing?
Yes; the 0.4 mm corner radius and stable edge properties of the T5115 grade make the insert appropriate for a range of finishing and semi‑finishing turning tasks in cast iron, depending on cutting conditions.

How should the TPMT16T304‑CM be identified in stock control?
Use the designation TPMT16T304‑CM T5115 together with SKU 6864805‑Tungaloy for unambiguous identification.
