TNMG220412 T6215 TNMG turning insert — Tungaloy, CVD-coated carbide for turning

The TNMG220412 T6215 is an ISO-format turning insert engineered for external and internal turning of stainless steels under stable to lightly interrupted cutting conditions.

• CVD-coated carbide, wear-resistant grade T6215
• Triangle insert, 60° cutting geometry
• 22 mm size, 4.76 mm plate thickness
• Double-sided with cylindrical locating hole

Increased process reliability for stainless steel turning

The CVD-coated cemented carbide grade T6215 offers a robust option when facing the adhesive wear and built-up edge typical of machining stainless steel. A CVD coating provides a hard, wear-resistant layer that improves edge retention and reduces flank wear; this translates into fewer tool changes and more consistent component quality. With the insert's double-sided design, the number of indexings per insert is maximised, which supports continuous production runs and lowers tooling costs over time.

Secure seating and consistent geometry for predictable results

Compatibility with turning holders follows ISO dimensions, but correct fit depends on form, clearance, tolerance class, fastening type, size and thickness. The triangular 60° geometry and 0° clearance deliver predictable chip formation for many turning tasks, while the 4.76 mm plate thickness adds rigidity for stable cuts. The cylindrical locating hole ensures positive seating and repeatable positioning in compatible holders, which helps to maintain part accuracy and surface finish across batches.

Practical technical advantages that simplify selection and setup

A 1.2 mm corner radius rounds the edge to balance strength and surface finish: larger radii resist chipping and improve tool life, while still enabling acceptable surface quality. The insert’s double-sided chipbreaker design gives two usable faces per side and supports effective chip control when the correct chipbreaker and grade are matched to material and cutting conditions. For general turning, select the chipbreaker and cutting data to suit material hardness and desired surface finish; the ISO format facilitates straightforward replacement in standard holders and simplifies inventory management.

FAQ

Which materials is this insert best suited for?
The TNMG220412 T6215 insert is formulated for machining stainless steel in stable to lightly interrupted turning operations; the CVD coating enhances resistance to adhesion and wear common with these alloys.

How is compatibility with holders determined?
Compatibility is determined by the insert’s form, clearance, tolerance class, fastening method, size and thickness; the TNMG220412 follows ISO dimensions but requires a matching ISO turning holder for correct seating.

How many indexable cutting edges are available per insert?
As a triangular, double-sided insert, the TNMG220412 provides six indexable cutting edges when both sides and all corners are used.

Is the T6215 coating suitable for interrupted cuts?
The T6215 grade is intended for stable to slightly interrupted conditions; for heavily interrupted cuts, a different grade or additional process measures should be considered.

What does the CVD coating provide compared with uncoated carbide?
A CVD coating forms a hard, wear-resistant layer over the cemented carbide substrate, improving edge life and reducing flank wear—especially beneficial when machining stainless steels that tend to cause built-up edge.
