SNMG120408 T6215 — Indexable turning insert for turning (Tungaloy)

A SNMG120408 T6215 indexable turning insert optimised for stable to slightly interrupted turning of rostfreier Stahl, offering CVD-coated carbide performance in an ISO-standardised format.

• CVD-coated carbide for rostfreier Stahl machining
• Square insert 12 mm x 12 mm, 4.76 mm thick
• Double-sided chipbreaker, 0.8 mm corner radius

Longer tool life through CVD-coated grade and wear resistance

The CVD-coated T6215 grade provides a durable cutting edge designed for machining rostfreier Stahl under stable to slightly interrupted conditions. The CVD-coated carbide structure combines a hard coating with a tough substrate, which delays flank and crater wear and reduces edge degradation. This results in extended service intervals and more consistent component dimensions during series production. For operations where material adhesion and work-hardening are concerns, the coated surface improves lubricity at the cutting zone, supporting repeatable surface finishes and reduced regrinding frequency.

Predictable integration with ISO systems for inventory and setup efficiency

As an ISO-conforming indexable insert from the ISO indexable turning inserts family, the component simplifies holder selection and stock-keeping. The insert’s square geometry and defined measures — 12 mm across the flats and 4.76 mm thickness — match common SNMG-compatible holders when form, clearance angle, tolerance class, clamping and thickness are aligned. The specified 0° clearance and a perpendicular seating (90°) support straightforward mounting and predictable cutting forces, reducing setup time and enabling reliable indexation when turning both external and internal features.

Improved chip control and edge stability for consistent finishes

Equipped with a double-sided chipbreaker and a 0.8 mm corner radius, this insert is tuned for controlled chip formation and robust edge strength. The chipbreaker geometry reduces long, stringy swarf and helps evacuate chips in interrupted cuts, lowering the risk of re-cutting and thermal spikes at the edge. For components where surface integrity matters, the combined effect of chip control and the CVD-coated edge supports superior surface quality and dimensional stability, with fewer secondary operations required.

FAQ

Is this insert suitable for machining rostfreier Stahl?
Yes. The SNMG120408 T6215 insert from Tungaloy is a CVD-coated carbide grade specified for machining rostfreier Stahl under stable to slightly interrupted cutting conditions.

Which toolholders are compatible with this SNMG120408 insert?
Compatibility is determined by the holder’s form, clearance angle (0°), tolerance class, clamping method, size and insert thickness; the SNMG120408 dimensioning aligns with standard SNMG holders.

What are the key dimensions and identifying numbers for ordering?
Size 12 mm, thickness 4.76 mm, corner radius 0.8 mm; Manufacturer article number 6944736 and SKU TUN6944736 identify the exact Tungaloy insert.

Can the insert be indexed on both sides?
The insert features a double-sided chipbreaker and is manufactured for reversible use, enabling renewed cutting edges after rotation or flipping as permitted by the insert geometry.

How does the chipbreaker benefit turning operations?
The double-sided chipbreaker improves chip control and evacuation, which reduces re-cutting, lowers thermal load on the edge and contributes to consistent surface quality when turning rostfreier Stahl.
