VNMG 120404 T6215 – VNMG120404E-TSF ISO turning insert (Tungaloy)

VNMG120404E-TSF T6215 is an ISO rhombic turning insert engineered for robust machining of stainless steels under stable to lightly interrupted cutting conditions

• CVD-coated carbide grade T6215
• Optimised for stainless steel turning
• Rhombic VNMG with 35° cutting angle
• 0.4 mm corner radius, cylindrical hole

Predictable performance through CVD coating and grade selection

The CVD-coated T6215 carbide composition is selected to provide high wear resistance and sustained cutting-edge strength when machining stainless steels. In practical terms, this means fewer unscheduled indexings and a steadier part finish over longer tool life, which supports uninterrupted production runs. The formulation is particularly suitable where cuts are stable or only lightly interrupted; under these conditions the coated grade reduces flank wear and helps maintain dimensional accuracy.

Geometry and dimensions that support surface quality and process control

The rhombic geometry with a 35° cutting angle and a 0.4 mm corner radius balances cutting forces and surface finish requirements. The insert’s dimensions — 12 mm inscribed circle, 4.76 mm thickness and a cylindrical hole — make it compatible with standard ISO VNMG holders, subject to matching form, relief angle and tolerance class. A 0° free angle is indicated on the datum; this geometry delivers a robust cutting edge for turning tasks where edge security takes priority over shear sensitivity, aiding repeatable results on contact-prone materials.

Simple system integration and application guidance

As part of a standard ISO tooling system the indexable insert works together with a suitable external holder or boring bar, plus underlay/shim, clamp set and replacement screws for secure mounting. The TSF chipbreaker supports controlled chip formation on stainless steels, limiting built-up edge and improving surface integrity. Typical uses include external and internal turning; the chipbreaker and grade should be selected according to the workpiece material, machining strategy and assembly rigidity.

FAQ

Which materials is this insert best suited to machine? The VNMG120404E-TSF in T6215 is primarily specified for machining stainless steels under stable to lightly interrupted conditions and delivers improved wear resistance compared with uncoated grades.

What chip control does the insert provide? The TSF chipbreaker fitted to this insert supports controlled chip formation on stainless steels, reducing built-up edge and aiding consistent surface finish during turning with the VNMG geometry.

What are the key dimensions to check for toolholder compatibility? Check the inscribed circle (12 mm), thickness (4.76 mm), corner radius (0.4 mm) and the 0° free angle; compatibility also depends on holder form, tolerance class and fastening method for secure clamping of the insert.

How does the T6215 grade benefit production runs? The T6215 CVD-coated grade offers enhanced wear resistance and stable cutting-edge life, which reduces the frequency of indexings and supports steady output and surface quality over longer cycles.

Can this insert be used for internal boring as well as external turning? Yes, the insert is suitable for both external and internal turning operations when paired with the correct holder type and when machining parameters match the workpiece material and cutting conditions.
