SNMG 120404 T6215 indexable turning insert — CVD-coated carbide, 0.4 mm radius (Tungaloy)

A SNMG 120404 T6215 indexable insert engineered for turning applications, optimised for stainless steel under stable to lightly interrupted cutting conditions.

• CVD-coated carbide grade T6215
• Designed for stainless steel turning
• 0.4 mm corner radius for fine finishes
• Square insert, 90° cutting angle

Reliable machining performance for demanding stainless steel work

The CVD-coated carbide substrate in this grade provides a stable cutting edge and consistent wear resistance, which translates into fewer indexings and predictable tool-change intervals. For workshop planners and production engineers, this means improved process stability during external and internal turning where material variability and occasional interruptions can otherwise shorten tool life. The insert’s double-sided chipbreaker aids in chip control, reducing downtime spent clearing swarf and supporting steady cycle times.

Geometry and edge preparation that improve surface quality

A modest 0.4 mm corner radius combined with the insert’s square form and 90° geometry produces a controlled cutting action that benefits surface finish and dimensional consistency. The short cutting edge radius reduces the tendency for edge chipping when machining stainless steels, while the CVD coating lowers friction and helps maintain surface integrity at elevated temperatures. These technical attributes convert directly into the commercial benefit of fewer reworks and more parts meeting tolerance on first pass.

System compatibility and practical handling for production environments

This ISO-designated insert is part of a modular system that includes a matching external holder or boring bar, a clamping pad and replacement screws; compatibility is determined by form, clearance angle, tolerance class, fixing method, size and thickness. The SNMG format and central hole with cylindrical style allow secure clamping and straightforward indexing. Keeping a consistent insert standard across toolrooms simplifies inventory management and speeds up set-up procedures, supporting lean manufacturing routines and efficient tool logistics.

Application guidance and decision criteria for selection

Select the chipbreaker and grade pairings based on workpiece stability, cutting conditions and material batch characteristics. The T6215 grade is recommended for stainless steel turning under stable to lightly interrupted conditions; for heavily interrupted cuts or unstable setups, a different combination of chipbreaker and grade should be considered. The insert’s 4.76 mm thickness and 12 mm size provide a robust platform for medium-duty turning, balancing stiffness with versatility in general workshop applications.
