TNMG160412 T6215 triangular indexable insert for turning by Tungaloy — CVD-coated cemented carbide, 60° geometry

A TNMG160412 insert designed for ISO-compatible external and internal turning, optimised for machining stainless steels under stable to slightly interrupted cutting conditions

• CVD-coated carbide grade T6215
• Optimised for turning stainless steels
• 60° triangle form with 1.2 mm radius
• Double-sided chipbreaker with cylindrical hole

Consistent wear resistance for stainless steel applications

The combination of a CVD-coated surface layer on a high-quality cemented carbide substrate provides improved resistance to abrasive and adhesive wear often encountered when machining stainless steels. This results in extended edge life and more predictable tool-change intervals, which in turn contributes to lower overall machining costs. The coating supports stable thermal behaviour at typical turning speeds, helping to maintain a consistent surface finish over longer production runs.

ISO geometry and secure seating reduce setup time

Configured to ISO standards, the triangular form with a 60° cutting angle and zero clearance wedge offers repeatable seating in standard external holders. Compatibility with the holder is determined by form, clearance angle, tolerance class, fixation method, size and thickness; correct matching ensures reliable clamp engagement and repeatable geometry. This standardisation simplifies tool management across multiple machines and reduces the risk of incorrect insert selection during changeovers.

Improved chip control and adaptability in mixed production

The double-sided chipbreaker design supports controlled chip formation across a range of stainless-steel alloys and cutting parameters. The insert’s cylindrical hole allows secure fastening and straightforward rotation or indexing, enabling two usable cutting edges per side and effective use of the insert’s life. As part of a system comprising a matching outside holder or boring bar, the arrangement enables fast replacement and minimises machine downtime while preserving process stability.

Choosing the right grade and handling recommendations

The T6215 grade is a wear-resistant, CVD-coated option intended specifically for turning rostfreier Stähle under stable to lightly interrupted conditions; it favours good edge life and surface integrity. Select a chipbreaker and insert size that suit the component material, depth of cut and machine rigidity. The 1.2 mm corner radius offers a balance between strength and finishing capability; larger radii improve edge robustness, while smaller radii help achieve finer detail. For inventory planning, consider spare screws and clamping sets as part of the insert system to maintain continuous production.
