TCMT 16T308 T515 — Tungaloy indexable turning insert for turning, CVD-coated carbide

The TCMT 16T308 T515 is an ISO-standard triangular indexable insert, designed for productive external and internal turning of cast iron where reliable chip control and cost-effective tool life are required.

• ISO-standard triangular insert, 60° geometry
• CVD-coated carbide grade T515 for cast iron
• 0.8 mm corner radius for improved surface finish
• Cylindrical hole with single-side countersink (40°–60°)

Productive cast-iron turning with controlled chips and stable life

The TCMT16T308 insert is a CVD-coated carbide solution optimised for machining cast iron: the T515 grade balances wear resistance and economy to extend tool life in continuous and interrupted cuts. The combination of a single-sided chipbreaker and a stable rake geometry promotes consistent chip control, reducing secondary operations and improving cycle time. The CVD-coated carbide layer increases thermal and abrasive resistance, which translates into fewer tool changes and a steadier process window for series production.

Reduced setup complexity through ISO compatibility and secure clamping

The ISO designation and standardised triangular form enable straightforward integration into existing tool inventories. Compatibility with holders depends on form, relief angle (7°), tolerance class, clamping method, size and thickness; specifying the ISO code 16T308 and the 60° included angle ensures correct mating with standard toolholders. The insert's cylindrical hole with single-side countersink (40°–60°) provides reliable clamping and repeatable seating, which helps to maintain tool alignment and repeatability across set-ups.

Select the right grade and handling for dependable results

Choosing the T515 grade and the appropriate chipbreaker should follow the workpiece stability and the nature of the cut: stable fixtures and continuous cuts favour higher feed and cutting speed, while interrupted cuts require conservative parameters and attention to clamping. The 0.8 mm corner radius helps to achieve improved surface finish without sacrificing edge strength, and the 3.97 mm thickness contributes to insert rigidity. For practical use, pair the insert with a matching underlay, clamp set and replacement screws as part of the tool system to preserve process reliability and reduce unplanned downtime.

FAQ

Which materials is this insert suitable for? This insert is intended primarily for machining cast iron; the T515 CVD-coated carbide grade provides wear resistance suitable for a wide range of cast-iron applications.

What are the key dimensions and geometry to note? Key specifications are the 60° triangular geometry, 0.8 mm corner radius and 3.97 mm thickness; these determine the cutting profile and holder compatibility for the TCMT 16T308 T515 insert.

How does the chipbreaker influence performance? The single-sided chipbreaker promotes controlled chips and consistent evacuation during turning, improving surface quality and reducing risk of built-up edge in cast-iron operations.

What clamping and accessories are required? Secure clamping via the cylindrical hole and single-side countersink (40°–60°) is recommended; pairing the insert with the correct underlay, clamp set and replacement screws ensures repeatable seating and process stability.
