CNMG 120408 T6215 CNMG120408 T6215 – Indexable turning insert for turning, Tungaloy

The CNMG120408 T6215 is an ISO-format indexable insert engineered for turning operations on stainless steel under stable to lightly interrupted cutting conditions.

• CVD-coated carbide for high wear resistance
• 0.8 mm corner radius for fine surface finishes
• ISO CNMG form for broad holder compatibility
• Cylindrical hole for secure clamping

Increased process reliability for stainless-steel turning

The CVD-coated carbide substrate of this ISO plate delivers enhanced wear resistance and predictable flank wear progression, which supports longer tool life and reduced downtime. Designed for turning applications, the insert’s double-sided chipbreaker aids consistent chip control during continuous cuts, while the 0° relief angle and 80° nominal geometry give stable cutting forces. These technical attributes translate into measurable productivity gains: fewer indexings, fewer interruptions and more consistent part quality in serial machining.

Geometry and mounting that speed up tool changes

Compatibility to the toolholder is ensured by standardised dimensions and form: the rhombic CNMG shape, 12 mm inscribed circle, and 4.76 mm thickness match common ISO holders. The cylindrical hole with secure seating and supplied clamp systems simplifies clamping and repeatability in high-volume setups. The 0.8 mm corner radius provides a balance between strength and surface finish, enabling reliable edge life while maintaining the ability to achieve tight tolerances. Where slotting or interrupted cuts are expected, the material and chipbreaker selection should be validated against workpiece stability.

Practical selection and application guidance for optimised output

When machining stainless steel, the T6215 grade offers a hard-wearing coating that reduces built-up edge and supports dimensional stability across batch runs. Selecting the correct chipbreaker and grade for the specific alloy and machining strategy is essential; matching the insert’s form, thickness and hole style to the holder prevents assembly errors and maintains cutting geometry. For process planners, the standardised ISO design enables straightforward inventory management and quick replacement, supporting continuous production and lower indirect costs per part.

FAQ

Is this insert suitable for stainless-steel turning?
Yes. The CNMG120408 T6215 insert is specified for turning stainless steel under stable to lightly interrupted conditions; the CVD-coated grade improves wear resistance and reduces built-up edge.

How is compatibility with existing holders determined?
Compatibility depends on plate form, freedom angle, tolerance class, fastening method, size and thickness; the ISO CNMG form and 12 mm inscribed circle ensure broad holder compatibility when dimensions match.

Can the insert be used on interrupted cuts?
The T6215 grade performs well under stable to slightly interrupted cuts; for heavy interruptions a different geometry or tougher substrate may be preferable.

What does the cylindrical hole mean for clamping?
The cylindrical hole provides consistent axial location and secure clamping seating, aiding repeatable positioning and straightforward replacement in standard clamping systems.

Is the insert reversible or single-sided?
This is a double-sided insert with indexable cutting edges, allowing rotation to a fresh edge and extending usable tool life.
