SNMG120404 T6215 indexable turning insert — ISO square insert for turning by Tungaloy

SNMG120404 T6215 is an ISO-standard square indexable insert engineered for external and internal turning applications, optimised for machining rostfreier Stahl under stable to mildly interrupted cutting conditions.

• CVD-coated carbide for enhanced wear resistance
• Designed for rostfreier Stahl machining
• Square ISO insert, 12 mm size, 4.76 mm thick
• Double-sided chipbreaker with cylindrical hole

Consistent tool life through CVD-coated carbide technology

The CVD-coated carbide substrate of this grade delivers enhanced wear resistance, which translates directly into longer tool life and more predictable process windows. Chemical vapour deposition (CVD) forms a thin, hard ceramic layer over the cemented carbide body that resists abrasive wear and built-up edge when machining rostfreier Stahl. For production runs where tool-change intervals must be predictable, this coating reduces downtime and supports steady component quality without complex process tweaks.

Easy integration into ISO tool systems for predictable set-up

As an ISO-standard square insert, the component offers predictable seating and clamping when used with matching holders. The compatibility is defined by insert form, clearance angle, tolerance class, fastening method, size and thickness; these parameters ensure the insert mounts securely and repeatedly. The item’s ISO designation and square geometry make it straightforward to match with standard external holders or boring bars, reducing trial-and-error at the machine and enabling rapid changeovers in multi-shift environments.

Stable cutting and improved surface control with targeted chip management

The double-sided chipbreaker supports controlled chip formation across a range of feeds and depths, improving surface finish and evacuation in turning operations. The moderate 0.4 mm corner radius balances edge strength with achievable surface quality: a small radius reduces cutting forces and helps maintain dimensional accuracy on thin-walled workpieces, while still offering sufficient edge robustness for standard interrupted cuts. Selecting the correct chipbreaker and grade according to workpiece material, machining strategy and machine rigidity is essential to unlock consistent productivity.

Clear dimensions and practical characteristics for shop-floor decisions

Key dimensions and design choices aid in process planning: the insert is a square plate with a nominal size of 12 mm, a plate thickness of 4.76 mm, a cylindrical hole for secure fastening and a 90° reference angle that suits general-purpose turning. The cutting grade T6215 is a CVD-coated carbide specifically intended for rostfreier Stahl; this combination supports stable chip formation and repeatable performance across series production. The compact geometry and standard hole style simplify stocking and replacement logistics for maintenance teams.
