TCMT 16T308 T6215 Turning Insert by Tungaloy — CVD-coated carbide, R0.8

The TCMT 16T308 T6215 is an ISO-standard triangular turning insert engineered for external and internal turning, optimised for machining stainless steels with stable to slightly interrupted cuts.

• ISO triangular insert TCMT 16T308
• CVD-coated carbide for wear resistance
• Designed for turning stainless steels
• 0.8 mm corner radius for controlled cutting

Consistent compatibility for reliable tool changeovers

The ISO-standard geometry ensures straightforward integration into common insert holders; ISO-standard form, relief and size mean that the insert fits accepted toolholder interfaces when form, clearance angle and tolerance class align. The insert is supplied as part of a complete system consisting of an indexable insert, suitable external holder or boring bar, and the necessary clamping pack. This system focus reduces setup time and facilitates predictable repeatability in serial production, supporting steady process throughput.

Wear-resistant coating engineered for stainless machining

The CVD-coated carbide grade offers high wear resistance and thermal stability, characteristics that help maintain edge integrity when machining stainless steels, which tend to work‑harden and generate heat. Chemical vapour deposition (CVD) produces a hard, adherent coating layer that resists abrasive wear; when combined with the underlying carbide substrate, it extends tool life and supports longer uninterrupted cycles, lowering tooling change frequency and contributing to improved productivity.

Geometry tailored for surface finish and chip control

A 0.8 mm (R0.8) corner radius balances strength at the cutting edge with the ability to achieve a fine surface finish on the workpiece; a larger radius increases edge robustness, while the chosen size keeps cutting forces manageable for common turning operations. The insert features a 7° relief angle and a thickness of 3.97 mm, together stabilising mounting and reducing vibration. The central cylindrical hole with a single-sided countersink (40°–60°) secures positive clamping and repeatable seating, while the triangular shape with a 60° included angle provides three usable cutting edges per index, improving cost efficiency per edge.

Productivity advantages and application guidance

With a one‑sided chipbreaker and a grade intended for stable to lightly interrupted cuts, the insert supports productive turning where consistent dimensional control and surface quality are priorities. Selection of feed, depth of cut and coolant strategy should match the grade’s strengths: moderate depths and steady feeds exploit the CVD-coated carbide’s wear resistance without provoking excessive heat. For components in stainless steel, this grade helps avoid premature edge failure and reduces rework, contributing to lower overall process cost and higher throughput.

FAQ

Can this insert be used for internal boring as well as external turning?
The TCMT16T308 T6215 insert is suitable for both external and internal turning operations when used with an appropriate external holder or boring bar and correct clamping pack.

What advantages does the T6215 grade offer for stainless steels?
The T6215 CVD-coated carbide grade provides improved wear resistance and thermal stability, reducing edge degradation when machining stainless steels under stable to lightly interrupted cutting conditions.

How many cutting edges are available per insert and how is it secured?
The triangular geometry provides three usable cutting edges; the insert is secured via a cylindrical hole with a single-sided countersink (40°–60°) for repeatable seating and positive clamping.

Is the corner radius suitable for precision finishes?
The 0.8 mm corner radius balances edge strength with surface finish capability, making it appropriate for many precision turning tasks while maintaining robust performance.
