TPMN 160304 T5115 turning insert — Tungaloy (CVD-coated carbide, for cast iron)

TPMN 160304 T5115 is a triangular ISO turning insert designed for external and internal turning, offering a universal grade T5115 for cast iron applications.

• ISO triangular insert TPMN
• CVD-coated carbide grade T5115
• Optimised for cast iron turning
• R0.4 nose radius, 11° clearance

Consistent cutting performance for cast iron turning

The CVD-coated carbide composition and the grade T5115 deliver a balanced combination of wear resistance and edge stability, which translates into predictable tool life and fewer insert changes in batch production. For shops machining cast iron, this leads to lower downtime and a more consistent surface finish. The standardised ISO geometry ensures straightforward replacement of worn inserts without trial fitting, supporting stable production cycles.

Precise geometry that improves dimensional control

With an 11° clearance angle and a 0.4 mm nose radius, the insert provides a compromise between fine surface quality and robust tool strength. The triangular form with an inscribed circle of 16 mm and a 3.18 mm thickness gives multiple cutting edges per insert, reducing tooling costs per component. These geometric details help maintain dimensional accuracy on turned parts while allowing moderate to aggressive feeds depending on the holder and machine rigidity.

Compatibility and system integration for smooth setup

The insert is part of the ISO turning insert system and requires a matching external holder or boring bar; compatibility depends on seat form, clearance, tolerance class, clamping method, size and thickness. Using ISO-compatible clamping sets and spare screws simplifies logistics and tool stock management. Selecting an appropriate holder and clamping package ensures optimal chip flow and clamping stability, resulting in fewer regrinds and consistent part quality.

Practical benefits and application guidance

As a universal choice for cast iron, the insert supports both roughing and semi-finishing when combined with the right machining parameters and a suitable cutting fluid. The absence of a dedicated chipbreaker in this grade means chip control should be matched to the workpiece and process — selecting feeds and depths that promote manageable chip shapes will protect the cutting edge and the workpiece surface. The carbide substrate and CVD coating help sustain cutting edge integrity under interrupted cuts and varying material hardness.

FAQ

What materials is this insert best suited for?
The TPMN 160304 T5115 insert is formulated as a universal grade for cast iron, offering a balance of wear resistance and edge stability for common grey and nodular cast irons.

Can the insert be used for both external and internal turning?
Yes, the ISO geometry of the TPMN 160304 insert suits both external and internal turning operations when paired with a compatible external holder or boring bar.

How does the R0.4 nose radius affect finish and strength?
A 0.4 mm nose radius provides improved strength at the cutting edge while permitting a good surface finish; it is a compromise between fine finishing radii and heavy-duty cutting edges.

Is there a chipbreaker on this grade?
This variant is supplied without a chipbreaker, so chip control must be achieved through appropriate feed, depth of cut and holder choice for reliable chip evacuation.

Which coating is applied and what advantage does it offer?
The insert uses a CVD coating, which enhances wear resistance and edge life under the thermal and mechanical loads typical of cast iron machining.
