TNMA 160408 T5105 – ISO triangular turning insert for high‑speed cast‑iron machining (Tungaloy)

The TNMA160408 T5105 is an ISO‑standard triangular turning insert engineered for high‑speed external and internal turning of cast iron under stable setup conditions.

• CVD‑coated carbide grade T5105 for wear resistance
• ISO TNMA 160408 triangular geometry, 60° angle
• 0.8 mm corner radius for robust edge strength
• Suitable for high‑speed cast‑iron turning

Consistent high‑speed cutting with wear‑resistant grade

The insert is made from CVD‑coated carbide designed as a wear‑resistant grade for demanding turning. The T5105 composition provides enhanced resistance to abrasion and thermal softening during elevated cutting speeds, which leads to longer tool life and reduced tool change intervals. In practice, this translates to a more predictable machining process and lower per‑part tooling costs when used in stable, well‑supported setups. The term CVD‑coated denotes a chemical vapour deposition layer that improves surface hardness and adhesion compared with uncoated substrates, enabling reliable performance in continuous production.

Predictable geometry for secure clamping and surface quality

The triangular TNMA form with a 60° included angle and a 0.8 mm corner radius offers a balance between edge strength and surface finish. The insert is provided with a cylindrical central hole and a plate thickness of 4.76 mm, so compatibility with clamping systems is determined by form, relief angle (0°), tolerance class, fastening method, size and thickness. These parameters ensure the insert seats correctly in standard indexable holders, minimising run‑out and enabling repeatable machining. A modest corner radius such as 0.8 mm reduces the risk of chipping while still allowing good workpiece finish on cast‑iron components.

Application guidance for efficient turning operations

Specified for turning, the insert is appropriate for both external and internal operations on cast iron where stable cutting conditions prevail. As supplied, the insert is without a chipbreaker, so chip control must be provided by the chosen holder geometry or by selecting an insert variant with an integrated chipformer when necessary. The ISO format simplifies replacement and inventory management within established tool systems. For process setup, pairing the insert with a rigid holder and optimised cutting parameters will yield improved surface integrity and consistent removal rates, supporting higher productivity and less rework.

FAQ

What materials is this insert primarily designed for?
The Tungaloy TNMA160408 T5105 insert is primarily intended for machining cast iron in high‑speed turning operations under stable conditions.

Does the insert include a chipbreaker for chip control?
This insert is supplied without a chipbreaker; chip control should be provided by the selected holder or by choosing a variant with an integrated chipformer when required.

How does the T5105 grade affect tool life?
The T5105 CVD‑coated carbide grade offers enhanced wear resistance and thermal stability, which extends tool life during continuous high‑speed turning and reduces downtime for replacements.

Which geometric parameters determine holder compatibility?
Compatibility is determined by the insert form, relief angle (0°), tolerance class, fastening method, size (16) and thickness (4.76 mm); correct matching ensures secure clamping and repeatable results.

Is the insert suitable for internal turning as well as external turning?
Yes, the insert is suitable for both external and internal turning when combined with an appropriate boring bar or internal holder that matches the ISO TNMA specification.
