TNMG160404 T505 turning insert — Tungaloy, CVD-coated carbide, 0.4 mm radius

The TNMG160404 T505 is an ISO-standard triangular indexable insert designed for general external and internal turning, optimised for economical machining of cast iron with a CVD coating that enhances wear resistance.

• ISO-standard triangular insert 16 mm
• CVD-coated carbide grade T505 for cast iron
• Double-sided chipbreaker for stable chips
• 0.4 mm corner radius, 60° geometry

Cost-efficient cast-iron machining with high wear resistance

The combination of a CVD-coated carbide substrate and the T505 grade delivers a balance between wear resistance and economical tool life, making this insert suitable where process stability and tool cost-efficiency matter. The coating reduces flank and crater wear during continuous turning, which extends effective edge life and lowers tool-change frequency. Compatibility with ISO toolholders is determined by form, clearance angle, tolerance class, fixing method, size and thickness, so the insert integrates into existing tool systems with predictable performance. This delivers measurable productivity benefits in batch production and recurring turning operations without demanding changes to the tool setup.

Stable chip control and repeatable geometry for consistent surface finish

The double-sided chipbreaker and the insert’s triangular form provide reliable chip formation and evacuation in routine turning tasks. The 0.4 mm corner radius and 60° cutting geometry support a controlled cutting edge suited to medium finishing and general turning, helping to achieve a consistent surface quality while maintaining dimensional accuracy. For interrupted cuts or less rigid set-ups, the choice of chipbreaker and grade should be matched to machine stability; selecting the correct combination reduces vibration and optimises tool life, which in turn supports consistent component quality.

Practical selection guidance for production-ready setups

Use this insert for both external and internal turning operations where cast-iron workpieces are predominant. The indexable design allows economical re-use of edges, and the system typically comprises the ISO insert, a compatible external holder or boring bar, a backing plate or clamping set and replacement screws. When integrating the insert, verify holder compatibility with the insert’s form, relief angle and thickness to ensure secure clamping and precise positioning. Choosing the correct chipbreaker and grade according to workpiece material, interruption severity and desired cut speed will improve efficiency and reduce machining costs in the long term.
