TNMG 160412 T6215 — TNMG160412 T6215 Tungaloy turning insert (CVD-coated carbide, 60° triangle)

TNMG160412 T6215 is a triangular, ISO-standard indexable insert designed for external and internal turning of stainless steels under stable to lightly interrupted cutting conditions

• CVD-coated carbide grade T6215
• ISO TNMG triangular 60° insert
• Double-sided with cylindrical hole
• Optimised for stainless steel turning

Reliable wear resistance for consistent production

The CVD-coated carbide grade T6215 delivers high wear resistance during continuous and lightly interrupted turning of stainless steels, extending in-process life and reducing frequent index changes. The coating creates a hard, thermally stable layer that limits flank wear and built-up edge formation; this makes the insert particularly suited for applications where predictable tool life is essential. The ISO construction also supports a standardised toolholding approach that improves machine uptime and process reproducibility.

Precision geometry for predictable surface quality

A 60° triangular shape with a 1.2 mm corner radius and a 0° relief angle produces a stable cutting edge geometry that balances strength and finish. The double-sided chipbreaker promotes controlled chip formation, improving evacuation and reducing chatter risk on long overhangs. The cylindrical centre hole enables secure clamping in compatible external holders or boring bars; compatibility depends on form, clearance angle, tolerance class, clamp type, size and thickness. This geometry yields consistent surface finish and dimensional repeatability in turning operations.

System-level efficiency that lowers cost per component

The insert’s indexable design enables multiple edges per insert, lowering tooling cost per component and speeding changeovers. The carbide substrate and CVD protection support sustained cutting at production feeds and speeds, while the ISO standardisation simplifies stocking and tool selection across machine parks. Choosing the appropriate chipbreaker and grade for the workpiece and stability reduces scrap and cycle time, translating into measurable process economy and more predictable batch throughput.

FAQ

What holder types are compatible with this triangular ISO insert?
Compatibility depends on holder form, relief angle, tolerance class, clamp type, size and thickness; the TNMG160412 T6215 insert is intended for standard external holders or boring bars designed for TNMG inserts and uses the cylindrical centre hole for secure clamping.

How does the chipbreaker affect machining stainless steel?
The double-sided chipbreaker on this grade controls chip shape and evacuation, reducing the risk of built-up edge and improving surface finish when turning stainless steels with the TNMG160412 Tungaloy insert.

Can this insert be used for interrupted cuts?
Yes, the CVD-coated carbide and robust triangular geometry provide stability for stable to lightly interrupted cutting conditions typical in many stainless-steel turning operations.

How many cutting edges are available per insert and how does that impact cost?
The triangular, double-sided design offers multiple index positions, which lowers cost per cutting edge and reduces downtime for insert changes, contributing to improved process economy.
