TNMG220412 T6215 Turning indexable insert (Triangle, 60°) — Tungaloy

A TNMG220412 T6215 indexable insert engineered for general turning, optimised for machining rostfreier Stahl under stable to mildly interrupted cutting conditions.

• CVD-coated carbide for enhanced wear resistance
• Double-sided chipbreaker for extended edge life
• 60° triangular geometry for robust cutting
• ISO‑compliant form for broad holder compatibility

Increase throughput with wear-resistant cutting edges

The combination of a CVD-coated carbide substrate and a wear-focused grade delivers a measurable improvement in tool life when machining rostfreier Stahl. Chemical vapour deposition (CVD) forms a hard, uniform coating that reduces flank wear and stabilises the cutting edge under elevated temperatures typical for stainless machining. As a result, cycle times can be maintained with fewer insert changes, supporting continuous production and predictable maintenance intervals. The tangible benefit is reduced downtime and lower cost per finished part.

Reliable geometry and secure clamping for consistent results

A 60° triangular geometry with a corner radius 1.2 mm provides an excellent balance between strength and profile control, making the insert suitable for both finishing and light roughing passes. The central cylindrical hole and ISO‑compliant form ensure secure location in standard holders, which minimises runout and promotes repeatable part accuracy. Clear tolerances in form and thickness simplify setup and reduce the need for trial runs, supporting reproducible machining processes and faster ramp-up on new jobs.

Flexible system use and clear material guidance

The double-sided chipbreaker offers two usable cutting edges per seat, improving cost-efficiency through edge indexing. Designed for external and internal turning, the insert integrates into the typical ISO system: insert, matching external holder or boring bar, shim/locating pad and clamping hardware. Selecting a chipbreaker and grade matched to the workpiece and operation optimises chip control and surface finish. The practical consequence is lower inventory complexity and a quick adaptation to varied parts, while preserving consistent surface quality.

FAQ

What materials is this insert suited to machine?
The TNMG220412 T6215 insert is specified for machining rostfreier Stahl and performs best under stable to mildly interrupted cutting conditions; the CVD coating helps manage heat and wear typical for these materials.

How does the CVD coating affect performance?
A CVD-coated carbide grade like T6215 provides a hard, thermally stable layer that reduces flank wear and extends edge life on the TNMG220412 insert, improving process stability and lowering tooling costs over time.

Is this insert compatible with standard holders?
The TNMG220412 follows ISO geometry and mounting dimensions, so it is compatible with ISO‑compliant external holders and boring bars when matching form, relief angle and tolerance class.

How many cutting edges are available per insert?
This triangular TNMG insert features a double-sided chipbreaker, providing two usable edges per seat and enabling economical edge indexing to extend service life.

What are the main benefits of the 60° geometry?
The 60° triangular design offers robust cutting edge strength and good access for a range of turning tasks, balancing resistance to chipping with the ability to achieve controlled surface finishes.
