SNMG120412 T6215 ISO indexable turning insert — CVD-coated carbide, 1.2 mm radius (Tungaloy)

The SNMG120412 T6215 is an ISO-standard indexable insert for external and internal turning, optimised for stable to lightly interrupted machining of stainless steels.

• CVD-coated carbide grade T6215
• Designed for stainless steel turning
• Double-sided chipbreaker for stability
• Square SNMG insert with 1.2 mm radius

High-performance grade for stainless steel machining

The CVD-coated carbide grade T6215 combines wear resistance with a cutting geometry tuned to stainless materials, reducing built-up edge and extending tool life. This formation yields a reliable process window under stable cutting conditions, which leads to fewer tool changes and increased uptime. The coating promotes consistent surface finish while permitting moderate cutting parameters for productive throughput.

Geometry that promotes process stability

A 1.2 mm corner radius and a square shape with a 90° included angle provide robust cutting edges that resist chipping during interrupted cuts. The double-sided chipbreaker helps control chip formation and evacuation, lowering the risk of workpiece damage and machine downtime. Together, these geometrical attributes enable accurate stock removal and consistent component tolerances when turning shafts, sleeves or bores.

Secure clamping and ISO compatibility

The insert is supplied in the ISO-standard SNMG size with a central cylindrical hole for fastening, ensuring secure attachment to compatible external holders or boring bars. The 0° clearance angle and plate thickness of 4.76 mm match common holder specifications, making integration into existing tool setups straightforward and minimising set-up time. Clear ISO standardisation simplifies logistics and holder selection across production lines.

Durable design focussed on repeatability

Manufactured from cemented carbide with a CVD coating, this insert offers repeatable performance across batches, improving process reproducibility and part quality. The combination of coating and substrate provides steady wear progression, which supports predictable tool-life planning and easier cost-per-part calculations. For operations prioritising stable runs with stainless steels, this insert supports both small-batch flexibility and larger production runs.

FAQ

What materials is this insert suitable for?
The insert is designed primarily for stainless steels; the T6215 grade and its CVD coating provide wear resistance and good surface quality when machining rostfreiem Stahl in stable conditions.

How is the insert clamped into the holder?
The SNMG120412 insert features a central cylindrical hole for secure fastening in compatible external holders or boring bars; the 4.76 mm thickness and ISO form ensure correct fitment.

What are the main advantages of the T6215 grade?
T6215 offers a CVD-coated carbide composition that emphasises wear resistance and stable cutting behaviour, which helps to extend tool life and maintain consistent results on stainless steels.

Can this insert be used for interrupted cuts?
Yes; the robust corner radius and double-sided chipbreaker make it suitable for stable to lightly interrupted machining where edge strength and chip control are required.
