SCMT120412-PM T6215 ISO turning insert for turning rostfreien Stahl — Tungaloy

The SCMT120412-PM T6215 is an ISO-format turning insert designed for external and internal turning of rostfreien Stahl under stable to lightly interrupted cutting conditions.

• CVD-coated carbide T6215 grade
• Optimised for rostfreien Stahl turning
• PM chipbreaker for consistent chip control
• ISO SCMT 120412 format, 1.2 mm radius

Improved surface finish through controlled chip formation

The combination of the PM chipbreaker geometry and the CVD-coated carbide substrate delivers controlled chip formation and predictable material flow during cutting. This reduces the risk of built-up edge and improves surface quality when working with rostfreien Stahl, where edge adhesion and work hardening can be problematic. The chipbreaker profile is intended for stable to slightly interrupted cuts and translates directly into fewer scrap parts and reduced secondary finishing. The result is a more efficient machining process and greater confidence in repeatability during series production.

Reliable clamping and exact fit in ISO toolholders

The insert follows the ISO format SCMT 120412, with a square 12 mm size, 1.2 mm corner radius and 4.76 mm thickness, making it compatible with a wide range of indexable turning holders. The cylindrical hole with one-sided countersink (40°–60°) secures the insert position and supports repeatable seating, while the 7° relief ensures the correct cutting clearance for conventional turning setups. Compatibility with a holder depends on form, relief angle, tolerance class, fastening method, size and thickness, which simplifies selection when matching to existing tool systems.

Durable grade and suitable applications for efficient production

The T6215 grade is a wear-resistant, CVD-coated carbide developed for machining rostfreien Stahl under consistent conditions. Its balanced toughness and coating hardness help maintain a stable cutting edge, extending tool life in productive turning operations. Typical uses include external profiling, finishing passes and moderate roughing where tool stability is good. When machining less stable setups or heavily interrupted cuts, selecting a different chipbreaker or adapting cutting data will preserve performance and minimise risk.
