TNMG160404 T6215 – ISO triangular indexable insert, CVD-coated carbide (Tungaloy)

The TNMG160404 T6215 is an ISO-standard triangular indexable insert designed for external and internal turning, optimised for stainless steel applications under stable to slightly interrupted cutting conditions.

• CVD-coated carbide grade T6215
• 0.4 mm nose radius for fine finishing
• 60° triangular geometry for versatile use
• Suitable for stainless steel turning

Longer tool life and consistent surface quality

The combination of a CVD-coated hard-wearing surface and a carbide substrate delivers reliable resistance to abrasive wear and edge chipping. This turning insert is engineered to maintain cutting edge integrity during long cycles, which translates into fewer indexings and less frequent tool changes. The coating reduces adhesion and thermal wear, helping to preserve dimensional accuracy and surface finish in serial production. For customers aiming to reduce downtime and increase process repeatability, this insert supports a more predictable machining window.

Precision seating and straightforward system integration

Produced to ISO dimensions, the insert’s geometry and tolerances support rapid integration into standard turning holders. Key compatibility factors are the insert form, 0° relief, tolerance class, fastening method, size and thickness. The TNMG shape with a 60° included angle offers an excellent balance of strength and access, while the 0.4 mm nose radius permits fine surface finishes without excessive cutting forces. The item is delivered for use with a matching external holder or boring bar, plus the appropriate shim/clamping set and replacement screws, ensuring a secure fit and consistent contact pressure for repeatable results.

Chip control and application guidance for stable cuts

This grade is intended for stable or lightly interrupted turning; selecting the correct chipbreaker and application parameters is crucial. The insert features a double-sided chipbreaker design that can be flipped to extend service life, and it performs best when combined with a holder and setup that limit vibration. For heavier interrupted cuts or unstable setups, a more robust grade or a different chip control geometry is recommended. When machining stainless steels, lower cutting speeds and moderate feeds often yield the best balance between tool life and surface quality; the insert’s construction helps maintain stable chip formation and reduces built-up edge tendency.

FAQ

What materials is this insert best suited for? The TNMG160404 T6215 insert is optimised for stainless steel applications and performs best under stable or slightly interrupted turning conditions.

How is the insert mounted in a holder? The insert features a cylindrical hole for secure mounting; compatibility depends on form, clearance angle, tolerance class, fastening, size and thickness of the holder system.

Can the insert be used on both external and internal turning operations? Yes, the ISO triangular format and the TNMG geometry make the insert suitable for both external and internal turning when paired with the correct holder.

What does the T6215 designation indicate? T6215 denotes a CVD-coated carbide grade engineered for wear resistance and consistent cutting performance in stainless steel turning.

How does the 0.4 mm nose radius affect machining? A 0.4 mm nose radius offers a good compromise between surface finish quality and edge strength, producing fine finishes without excessive cutting forces.
