SCMT 120404 T6215 — ISO turning insert by Tungaloy, CVD-coated carbide

The SCMT120404 T6215 is an ISO-style indexable turning insert engineered for stable to lightly interrupted turning of stainless steel components.

• CVD-coated carbide for high wear resistance
• ISO size 120404 for standard toolholders
• Optimised for stainless steel turning
• 7° relief angle and 0.4 mm corner radius

Consistent tool life and predictable productivity

The combination of a CVD surface layer and a robust carbide substrate provides elevated wear resistance and thermal stability, which translates into longer cutting edge life and fewer regrinds. For production environments where cycle time and surface quality matter, this grade reduces unplanned downtime and supports steady throughput. The result is measurable efficiency: fewer tool changes and a more predictable maintenance rhythm.

Geometry tailored to stable stainless-steel turning

The insert’s 0.4 mm corner radius and 7° relief angle optimise chip formation and contact conditions at the cutting edge, improving surface finish on demanding alloys. The 90° included angle yields a versatile cutting profile for both external and internal turning operations, while the one-sided chipbreaker is designed to control swarf when machining ductile, adhesive materials. These geometric choices make the insert well suited to operations requiring consistent dimensional accuracy and repeatable finishes.

Easy integration into existing ISO tool systems

As an ISO-indexable insert, compatibility is determined by form, relief angle, tolerance class, mounting method, size and thickness; matching these parameters ensures secure clamping and correct cutting geometry. The SCMT120404 format and the cylindrical hole with one-sided countersink (40°–60°) support standard clamping systems and spare-part logistics, simplifying inventory and tool-change routines.

Practical handling and production confidence

The CVD-coated grade T6215 balances wear resistance with predictable edge behaviour under stable to lightly interrupted cuts, reducing edge chipping and guarding component integrity. This contributes to lower scrap rates and steadier process capability, which in turn supports higher overall equipment effectiveness. The insert’s standard ISO form factor also enables fast replacement and minimal operator training, creating a practical, reliable solution for serial turning tasks.

FAQ

What materials is this insert best suited for? The Tungaloy SCMT120404 T6215 insert is developed primarily for machining stainless steel under stable to lightly interrupted cutting conditions.

Is the insert compatible with standard ISO external holders? Yes, the SCMT120404 form follows ISO dimensions; compatibility depends on matching form, relief angle, tolerance and thickness with the chosen holder.

What does the T6215 grade provide compared with other grades? T6215 is a CVD-coated carbide grade offering enhanced wear resistance and thermal stability suited to adhesive materials like stainless steel, helping to extend tool life.

How does the 0.4 mm corner radius affect part finish? A 0.4 mm radius helps produce a robust cutting edge that smooths the surface finish while maintaining dimensional control on turned components.

Can the insert cope with light interruptions or hard inclusions? The insert is intended for stable to lightly interrupted conditions; for heavy interruptions or severe inclusions, consult tooling specialists for a suitable alternative.
