TNMA 220408 T5125 triangular 60° indexable turning insert for turning — Tungaloy

The TNMA220408 T5125 is an ISO‑standard triangular indexable insert engineered for external and internal turning, optimised for interrupted cuts and less stable machining conditions.

• CVD-coated carbide grade T5125
• Optimised for interrupted cuts in cast iron
• Triangular 60° form for versatile turning

Consistent cutting performance where stability is limited

The insert’s CVD‑coated carbide composition delivers a balance between toughness and wear resistance, which is particularly advantageous for turning operations with intermittent engagement. The coated grade reduces flank wear and preserves edge integrity during shock loading, meaning longer tool life and fewer indexings. This results in steadier cycle times and reduced tool-change interventions, supporting productive turning routines even when machine or workpiece stability is not ideal.

Geometry designed for flexible turning strategies

A 60° triangular shape combined with a 0.8 mm nose radius offers a compromise between strength and surface finish: the acute geometry allows access to tight contours and internal faces, while the rounded nose helps maintain surface quality without sacrificing edge robustness. The triangular platform provides three usable corners per insert, improving economy per insert and enabling quick re‑indexing during high‑mix production.

Straightforward integration into ISO holders

Designed to the ISO indexable insert series, the component fits standard external holders and boring bars provided the form, clearance angle, tolerance class, mounting and thickness match. The insert thickness of 4.76 mm and the 22 mm seat size are typical values for this family, while the cylindrical centre hole ensures secure clamping and repeatable positioning. Compatibility with existing toolholders simplifies toolroom stocking and reduces setup time.

Material and application guidance for better results

The T5125 grade is a tougher carbide variant developed for machining cast iron in interrupted conditions and where damping is suboptimal. As the insert comes without a chipbreaker, choose cutting parameters and coolant strategy that favour chip control for your specific casting or grey‑iron grades. For conventional steels or materials requiring a different cutting geometry, select an alternative grade or chipbreaker suited to the workpiece to optimise surface finish and tool life.

FAQ

What materials is this insert best suited for? The TNMA220408 T5125 insert is formulated for machining cast iron and performs well in interrupted cuts and less stable conditions due to its tougher carbide and CVD coating.

Does the insert fit standard ISO holders? Yes. The insert follows ISO indexable insert dimensions; compatibility depends on holder form, clearance angle, tolerance class, mounting and thickness.

Is a chipbreaker included with this insert? No. This insert is supplied without a chipbreaker; chip control must be managed by cutting parameters, coolant and toolpath strategy.

How many usable cutting edges does the triangular insert provide? The triangular 60° geometry offers three usable corners, enabling economical re‑indexing and extended service life before replacement.

Which SKU should be referenced when ordering or enquiring? Please reference SKU 6850314-Tungaloy or manufacturer SKU TUN6850314 for availability and technical enquiries.
