TNMA 160408 T505 indexable insert — triangular 60° turning insert by Tungaloy, CVD-coated carbide for cast iron machining

TNMA 160408 T505 is an ISO-designation triangular indexable turning insert intended for economical machining of cast iron, supplied by Tungaloy

• CVD-coated carbide for cast iron
• Triangle form with 60° geometry
• 0.8 mm corner radius
• 4.76 mm plate thickness
• With cylindrical hole for clamping

Consistent cutting performance for cast iron with economical life

The T505 grade is a CVD-coated carbide developed for the economical machining of cast iron, offering a balance between wear resistance and cost efficiency. The coating enhances heat resistance and reduces flank wear, which in turn supports longer intervals between indexing or replacements. Where interrupted cuts or unstable setups occur, the choice of grade and chip control becomes decisive; this insert’s composition is aimed at stable chip formation and predictable wear behaviour, helping to maintain component quality across production runs.

ISO compatibility and secure clamping for straightforward tool assembly

Designed to the ISO geometry, the TNMA designation ensures predictable mating with matching holders when form, 0° relief, tolerance class, clamping method, size (16 mm) and thickness (4.76 mm) are observed. The insert is triangular with a 60° included angle and features a cylindrical hole for screw retention, allowing use with a standard external holder or boring bar together with a shim/clamp set and replacement screws. Clear selection and verification of the holder and fastening parts reduce downtime and simplify tool changes, supporting steady throughput in workshop environments.

Productivity gains through multiple cutting edges and practical system integration

The triangular shape provides three usable cutting edges, which supports efficient indexing and lowers overall tooling consumption per part. When integrated into a matching tool system, the insert contributes to measurable productivity improvements by reducing changeover time and improving process reliability. For optimal results, pair the insert with a holder matched to the component stability and machining parameters; while this grade is optimised for cast iron, selecting an appropriate chipbreaker or another grade will adapt the same ISO geometry for different workpiece materials or cutting conditions.

FAQ

Which materials is this grade intended for? The T505 grade is designed for the economical machining of cast iron; the TNMA 160408 insert performs best on grey and nodular cast irons where the coating and substrate support stable cutting.

How does the TNMA160408 designation relate to the insert geometry? TNMA160408 denotes an ISO triangular insert geometry with a 60° included angle; this specific article is size 16 with a thickness of 4.76 mm and a 0.8 mm corner radius, as supplied under the Tungaloy SKU 6831359-Tungaloy.

What should be checked for holder compatibility? Compatibility is determined by form, relief angle (0°), tolerance class, clamping method, size and thickness; the TNMA 160408 requires a matching triangular seat and a holder accepting a cylindrical-hole screw clamp.

Does this insert include a chipbreaker? This insert is supplied without a chipbreaker; if chip control is required for specific cast-iron grades or unstable conditions, choose an insert grade or geometry with a suitable chipbreaker.

How many cutting edges are available per insert? The triangular shape provides three usable cutting edges, allowing efficient indexing and reduced tooling costs per machined part.
