SNMG120412 T6215 turning insert – CVD-coated carbide, 1.2 mm radius by Tungaloy

SNMG120412 is an ISO-format turning insert designed for external and internal turning, optimised for stable to lightly interrupted machining of rostfreier Stahl.

• CVD-coated carbide wear resistance
• Square form for 90° shoulder turning
• Double-sided chipbreaker for economy
• Compatibility with ISO holders

Stable machining and consistent process reliability

The CVD-coated carbide grade T6215 delivers high wear resistance under continuous and slightly interrupted cuts, ensuring predictable tool life and fewer tool changes. The combination of a 1.2 mm radius and a square plate geometry provides robust edge strength for shoulder and profile turning while maintaining dimensional stability. For process planners and production managers, this results in lower downtime and a more constant production flow, backed by the insert’s ISO conformity.

Fast tool changes and assured compatibility

The insert’s ISO designation and standardised form guarantee straightforward integration with matching external holders and boring bars. The cylindrical hole and standard thickness simplify clamping and replacement routines, reducing set-up time. Because compatibility depends on plate form, relief angle, tolerance class, fastening and thickness, selecting holders that match these parameters avoids mismatches and accelerates tool swaps on the shop floor.

Coating and substrate explained for practical use

The cutting material is Hartmetall (carbide) with a CVD coating that enhances abrasion resistance and thermal stability during turning. This surface treatment suits applications with elevated temperatures and abrasive contact, particularly when machining rostfreier Stahl, where built-up edge and adhesion can shorten tool life. Choosing the T6215 grade means prioritising stable cutting conditions and reliable edge retention over aggressive high-feed strategies.

Recommended applications and handling guidance

Ideal uses include external and internal turning where stability is moderate and interruptions are light; the double-sided chipbreaker supports economical indexing for two cutting edges per side. The 0° relief angle and 90° plate orientation make the insert especially suitable for shoulder work and precise finishing passes. For best results, match feed and speed to the workpiece alloy and machine rigidity and prefer steady chip evacuation to maintain surface finish and tool life.
