TNMA 160404 T505 — Tungaloy turning insert for external and internal turning, CVD-coated carbide, 60° triangle

The TNMA160404 T505 is an ISO-standard triangular turning insert designed for efficient machining of cast iron in both external and internal turning applications

• CVD-coated carbide grade T505
• Optimised for cast iron machining
• ISO TNMA triangular insert, 60° included angle

High-efficiency grade for cast iron machining

The CVD-coated T505 grade combines the wear resistance of a carbide substrate with a protective hard coating to deliver an economical balance between tool life and cutting performance. This specification is developed for the economical machining of cast iron, providing stable cutting behaviour under typical turning conditions. The result is predictable tool life and fewer index changes, which supports a more continuous production flow.

Geometry and mounting explained for reliable fit-up

The triangular TNMA form with a 60° included angle and a corner radius of 0.4 mm offers versatile edge options for profile work and finishing passes. Plate thickness is 4.76 mm and the insert is supplied with a cylindrical hole, enabling secure clamping in compatible holders or boring bars. Compatibility is determined by insert form, clearance angle, tolerance class, fastening and size, so selecting a matching ISO-style external holder or clamp set ensures correct seating and repeatable concentricity.

Operational benefits and selection guidance for process stability

Delivered without a chipbreaker, this insert is suited for customers who choose the chip control that matches their material and process; select an appropriate chipformer and cutting parameters according to workpiece stability and whether cuts are continuous or interrupted. The combination of indexability, straightforward clamping and the T505 coating supports cost-effective turning operations, reduced downtime and consistent surface quality when machining cast iron components.
