SNMG 120412 T6215 Turning Insert by Tungaloy — CVD-coated carbide for stainless steel

A SNMG120412 T6215 indexable turning insert engineered for stainless steel machining, offering a robust 1.2 mm corner radius and a double-sided chipbreaker for controlled chips and reliable surface finish.

• CVD-coated carbide for wear resistance
• Optimised for stainless steel turning
• ISO SNMG form for broad holder compatibility
• Double-sided chipbreaker with 1.2 mm radius

Consistent cutting performance and extended edge life

The CVD-coated substrate of the T6215 grade is designed to resist abrasive wear and to sustain cutting edge integrity during stable to lightly interrupted turning of stainless steel. Owing to the protective coating, heat and adhesion at the cutting zone are reduced, which leads to more predictable tool life and fewer unplanned tool changes. This insert is therefore suitable where consistent productivity and low variance in component quality are required, and its wear behaviour has been optimised for long series and repeatable setups.

Straightforward match with ISO tooling systems

Manufactured to the ISO SNMG form, the insert guarantees uncomplicated matching with standard external and internal turning holders when the correct form, clearance angle, tolerance class, fixing method, size and thickness are observed. The square plate geometry with a 90° included angle and a 0° free angle simplifies fixture choices and supports robust clamping. This standardisation reduces tooling inventory complexity and enables efficient replacement across multiple machines and tool posts, supporting lean workshop logistics and predictable setup times.

Predictable chip control and improved surface finish

The integrated double-sided chipbreaker was developed for controlled chip fragmentation in conjunction with the material-specific cutting data associated with stainless steel. The rounded 1.2 mm corner radius balances edge strength and finish quality: it provides enough robustness for interrupted cuts while still permitting an acceptable surface condition on turned parts. Proper chip control decreases the risk of workpiece or tool damage, lowers rework rates and contributes to consistent batch-to-batch surface quality.

System-level benefits for productivity and inventory

The insert is supplied as part of an ISO-compliant system consisting of the insert itself, matching external holders or boring bars, a clamping pad or screw set and replacement screws when required. The documented specifications—thickness, inscribed size and hole style—support clear ordering and spare-part management, reducing downtime in production environments. For operations aiming to combine productivity with process stability, the insert’s combination of coating, substrate and geometry delivers an economical balance between lifetime and performance.

FAQ

Is this insert suitable for turning stainless steel?
Yes. The SNMG120412 T6215 insert uses a CVD-coated carbide grade optimised for stainless steel, providing wear resistance and stable chip formation under typical turning conditions.

Which holders are compatible with this insert?
Holders built for the ISO SNMG form and matching the plate size, thickness and square geometry are compatible; the SNMG120412 specification (12 mm inscribed circle, 4.76 mm thickness, 90°) should be used to select the correct external holder or boring bar.

How many cutting edges are available per insert?
The insert is double-sided with two usable edges; it can be indexed to present a fresh edge when required, supporting economical edge usage.

What corner radius and chip control does the insert offer?
The insert features a 1.2 mm corner radius combined with a double-sided chipbreaker, balancing edge robustness and surface finish while promoting controlled chip formation for stainless steel.

What is the coating and substrate of the insert?
This product uses a CVD-coated carbide substrate in the T6215 grade, chosen for its wear-resistant and process-stable characteristics during turning.
