CNMG 120412 T6215 — CNMG120412 indexable turning insert for turning — Tungaloy

CNMG120412 T6215 Tungaloy-Wendeplatte is an ISO-standard indexable insert designed for general turning applications, especially for rostfreier Stahl under stable to lightly interrupted machining conditions

• CVD-coated carbide for long tool life
• Rhombic CNMG shape with 80° approach angle
• Double-sided chipbreaker for consistent chips
• Cylindrical hole for secure clamping

Consistent wear resistance for rostfreier Stahl machining

The T6215 CVD-coated carbide grade provides consistent wear resistance, making it suitable for continuous turning of rostfreier Stahl where edge stability is critical. The coating reduces flank and crater wear, which extends service intervals and supports predictable tool-change cycles; this leads to fewer interruptions and a higher effective machining time per tool. Compatibility with ISO tooling means the insert integrates into established toolholding systems provided form, clearance angle and thickness match, ensuring straightforward adoption on existing lathes without elaborate adjustments.

Geometry engineered for precision and surface quality

The rhombic CNMG geometry with an 80° approach angle and 1.2 mm nose radius delivers a balance between strength and finish. The insert’s 4.76 mm thickness and robust body reduce vibration, improving surface finish on external profiles while the double-sided chipbreaker produces controlled chips for stable cutting forces. The cylindrical hole and standard fixing arrangement ensure repeatable seating and clamping, preserving cutting edge position after indexing and thus reducing setup variability and scrappage.

System-level benefits that support productivity

Integrated into a system comprising a suitable external holder, clamp set and replacement screws, this insert contributes to efficient production workflows. The T6215 grade is optimised for stable to lightly interrupted cuts; therefore, when paired with the correct holder and cutting parameters, the insert delivers predictable tool life and consistent surface quality. Select the chipbreaker and grade according to workpiece material and machining stability to fully exploit the insert’s advantages: less downtime for tool changes and improved process reliability.

FAQ

Which materials is this insert intended for? The CNMG120412 T6215 insert is optimised for machining rostfreier Stahl and is suitable where a wear-resistant grade is required for stable turning operations.

Is the insert indexable and reversible? Yes, the insert is double-sided and indexable; both sides can be used to extend service life before regrading is necessary.

How does the T6215 grade affect tool life compared with standard grades? T6215’s CVD-coated carbide composition improves flank and crater wear resistance, which typically increases tool life and reduces the frequency of tool changes in rostfreier Stahl machining.

What must be checked to ensure holder compatibility? Compatibility depends on matching the insert form (CNMG), clearance angle (0°), tolerance class, fastening method, size (12 mm) and thickness (4.76 mm) with the chosen external holder and clamp system.
