CNMG090408 T6215 turning indexable insert — Tungaloy, CVD-coated carbide

The CNMG090408 T6215 insert is a rhombic, ISO-standard indexable insert engineered for general-purpose external and internal turning of stainless steels under stable to lightly interrupted cutting conditions.

• CNMG 090408 geometry, 80° angle
• CVD-coated carbide grade T6215
• Optimised for turning stainless steels
• Double-sided chipbreaker, cylindrical hole

High wear resistance for reliable stainless-steel turning

The CVD-coated T6215 grade provides enhanced wear resistance, extending tool life in demanding stainless-steel applications. The coating reduces flank and crater wear while the substrate carbide maintains edge stability, which together support longer uninterrupted production runs and fewer tool changes; this translates into improved process economy and predictable component quality. The result is a measurable performance advantage when machining corrosion-resistant alloys where built-up edge and work-hardening are common challenges.

Precision geometry that ensures compatibility and repeatability

The CNMG090408 geometry with an 80° approach angle and a 0.8 mm nose radius delivers a balance between strength and surface finish. The insert is rhombic in form and 4.76 mm thick, with a cylindrical hole and double-sided chipbreaker that facilitate indexing. Compatibility with clamping systems depends on form, relief angle, tolerance class, fastening method, size and thickness; checking these parameters ensures correct seating in the holder and consistent repeatability during batch production. The ISO-standard design simplifies tool procurement and replacement across machines.

Practical application advice and process benefits

Designed for both external and internal turning, the insert’s double-sided chipbreaker supports effective chip control in many stainless-steel turning operations. Selecting the appropriate chipbreaker geometry and grade for the workpiece material and stability of the setup will reduce vibration and improve surface quality. In stable to lightly interrupted cuts the combination of the CVD coating and carbide base delivers good edge retention and consistent results, making the insert suitable for medium to high-productivity environments where dependable performance and predictable tool change intervals are valued.

FAQ

What materials is the CNMG090408 T6215 insert best suited for?
The CNMG090408 T6215 indexable insert from Tungaloy is optimised for stainless steels, offering wear resistance and chip control under stable to lightly interrupted cutting conditions.

How can compatibility with an existing holder be ensured?
Compatibility depends on the insert’s form, relief angle, tolerance class, fastening, size and thickness; verify these parameters against the holder specification before fitting the CNMG090408 T6215 insert.

Is the insert reversible or indexable on both sides?
Yes, the CNMG090408 T6215 features a double-sided chipbreaker, enabling indexing and extending usable edge life per insert.

What are the key geometry details to check when planning a process?
Refer to the 80° approach angle, 0.8 mm nose radius, rhombic shape and 4.76 mm thickness when selecting feeds, speeds and clamping arrangements for consistent results.

Can the CNMG090408 T6215 handle interrupted cuts?
The grade is designed for turning under stable to lightly interrupted conditions; for heavy interruptions consider a different grade or enhanced clamping/stiffness in the setup.
