WNMA080404 T5105 ISO turning insert, trigon form — Tungaloy

The WNMA080404 T5105 is an ISO-standard trigon indexable insert designed for high-speed external and internal turning of cast iron under stable conditions.

• CVD-coated carbide grade T5105
• ISO WNMA080404 trigon form
• Optimised for high-speed machining of cast iron

Engineered for efficient high-speed cast iron turning

The combination of CVD-coated carbide and the T5105 wear-resistant grade delivers consistent performance during sustained high-speed operations on cast iron. The coating increases abrasion resistance and thermal stability, so the cutting edge stays sharper for longer under the heat and abrasion typical of grey and nodular cast iron machining. This results in reduced tool changes and a more economical cycle time, supporting continuous production runs without compromising surface quality.

Predictable fit and robust cutting geometry for stable results

Built to an ISO standard, the trigon plate with its 0° relief angle and cylindrical hole ensures a reproducible fit in compatible holders and repeatable positioning at every index. The modest 0.4 mm corner radius balances edge strength and finish capability: it reduces chipping risk while still enabling a fine surface texture when conditions are stable. These dimensional and tolerance aspects determine compatibility by form, clearance angle, tolerance class, fastening, size and thickness, helping to avoid surprises at tool change and to secure predictable tool life.

Practical system approach for productive turning operations

As part of a complete turning system — insert, matching external holder or boring bar, shim/clamp set and spare screws — this indexable insert simplifies workshop logistics. The absence of a dedicated chipbreaker means chip control must be addressed via cutting parameters and toolholder choice; for many stable set-ups the plain trigon profile gives consistent chip formation on grey cast iron. Selection of the correct breaker and grade according to workpiece material, machining method and machine stability will deliver the main productivity gains and process security sought in production environments.

FAQ

Which materials are best suited to this insert?
The WNMA080404 T5105 insert is optimised for machining cast iron; its T5105 CVD-coated carbide composition provides superior wear resistance in high-speed cast iron applications.

How does the trigon form affect holder compatibility?
The trigon form and the ISO designation ensure compatibility when the holder matches form, clearance angle, tolerance class, fastening, size and thickness; correct pairing guarantees stable seating and repeatable geometry.

Is there a chipbreaker on this insert?
This variant is supplied without a chipbreaker, so chip control relies on cutter geometry, holder choice and cutting parameters suited to the machining stability and the specific cast iron grade.

What does the 0.4 mm corner radius mean for surface finish?
A 0.4 mm corner radius provides a compromise between edge strength and finishing capability, lowering chipping risk while enabling a good surface quality in stable cutting conditions.

Can this insert be used for internal turning?
Yes — the insert is suitable for both external and internal turning when paired with an appropriate boring bar or internal holder that accommodates WNMA080404 geometry and fastening.
