TCMT 16T308 T505 turning insert — triangular ISO insert for turning by Tungaloy

TCMT 16T308 T505 is an ISO‑standard triangular turning insert intended for efficient external and internal turning, optimised for machining cast iron in industrial production settings.

• ISO‑standard triangular insert (TCMT 16T308)
• CVD-coated carbide grade T505 for cast iron
• 0.8 mm corner radius for stable chip formation
• Single-sided chipbreaker with centring hole

Consistent chip control and economical machining

The CVD-coated T505 grade provides a balance between wear resistance and cost-efficiency, making it well suited to economical machining of cast iron. The combination of the coated carbide substrate and the single-sided chipbreaker results in predictable chip control, reducing interruption from irregular chips and helping to maintain steady cycle times. This effect translates into fewer tool changes and more productive machining periods, particularly in series production where process stability is essential.

Reliable fit, easy interchange and holder compatibility

Designed to ISO conventions, the triangular insert ensures straightforward interchangeability with compatible holders. The ISO standard geometry, the 7° relief angle, and the specified thickness of 3.97 mm permit secure clamping and repeatable positioning, which reduces setup time and the risk of runout. The insert’s cylindrical hole with one‑sided countersink (40°–60°) supports positive centring and safe fixation in a wide range of external holders or boring bars, streamlining inventory by allowing use of standardised tool bodies.

Application guidance to maintain productivity and surface quality

The 0.8 mm corner radius and the triangular shape are chosen to combine edge strength with the ability to generate the desired surface finish in turning operations. For interrupted cuts or unstable setups, select the appropriate chipbreaker and consider reduced depths of cut to preserve edge life and stability; for continuous, stable conditions, the T505 grade offers consistent wear behaviour. If material or process parameters require finer tuning, technical consultation is recommended to align chipbreaker geometry and cutting speeds with the workpiece characteristics.

FAQ

What materials is this insert best suited for? The insert is optimised for machining cast iron; the T505 CVD-coated carbide offers a combination of wear resistance and economical performance for grey and nodular cast irons.

Which dimensions and angles define the insert? The insert is the TCMT16T308 form with a 0.8 mm corner radius, 7° relief angle, 3.97 mm thickness and a 60° included angle, matching ISO turning insert specifications.

How does the chipbreaker affect performance? The single-sided chipbreaker supports controllable chip flow when turning cast iron, improving chip evacuation and cutting stability under typical turning conditions.

Can this insert be used for internal turning? Yes — the triangular ISO form and centring hole permit use in suitable boring bars as well as external holders, provided the holder matches the ISO geometry and clamping requirements.

What should be considered for interrupted cuts or unstable setups? For interrupted cuts and less rigid setups, choose a chipbreaker and cutting parameters that favour edge strength and reduced impact; the 0.8 mm corner radius helps balance strength and finish.
