TNMG 160404 T505 – Indexable Turning Insert for Turning by Tungaloy (CVD-coated carbide, 60°)

The TNMG 160404 T505 is an ISO-standard indexable turning insert designed for external and internal turning, optimised for economical machining of cast iron.

• CVD-coated carbide for wear resistance
• Triangular 60° geometry for versatile turning
• Double-sided chipbreaker for reliable chip control

Increased economy and tool life when machining cast iron

The CVD-coated cemented carbide grade T505 is formulated for economical and consistent machining of cast iron. The coating improves surface hardness and thermal resistance, which reduces flank wear under typical turning conditions. As a consequence, cycle times can remain stable for longer and insert changes are less frequent, contributing to lower overall machining costs. For production-minded workshops this translates into predictable running times and improved part-to-part repeatability.

Clear compatibility and secure clamping for ISO holders

The insert follows ISO geometry conventions, so compatibility depends on the holder's form, tolerance class, fastening and size. The triangular 60° geometry and 0° clearance suit a broad range of external and internal turning operations, while the cylindrical hole ensures positive and secure seating on the clamping assembly. The 4.76 mm thickness and 16 mm inscribed circle provide structural rigidity for moderate to heavy cuts, helping to avoid chatter when the holder, support and machine setup are correctly selected.

Stable chip control and consistent surface quality

This grade is supplied with a double-sided chipbreaker that supports repeatable chip segmentation when machining interrupted or continuous cuts in cast iron. The combination of geometry, chip control and the CVD coating helps achieve an improved surface finish with fewer rework cycles. For operators who prefer concrete parameters: the 0.4 mm corner radius aids edge strength and smoother entry/exit, reducing the risk of built-up edge on grey cast iron while preserving dimensional accuracy.

FAQ

What materials is this insert optimised for?
The TNMG 160404 T505 insert is optimised for cast iron machining; the CVD-coated carbide composition provides heat resistance and stable wear when turning grey and nodular cast irons.

Can this insert be used in standard ISO triangular holders?
Yes. The TNMG 160404 T505 follows ISO geometry; holder compatibility is determined by form, tolerance class, fastening and insert size so the correct ISO triangular holder and clamping set should be selected.

How does the T505 grade affect productivity?
The T505 grade provides a balance of wear resistance and edge stability, which supports longer tool life and consistent surface finish, reducing downtime for insert changes and post-process rework.

Is the insert reversible and what advantage does that provide?
This is a double-sided insert, allowing indexation to an unused cutting edge; this extends usable life per insert and reduces tooling costs for repetitive turning operations.
