DNMG 150412 T6215 Tungaloy turning insert for ISO turning — rhombic 55° geometry

DNMG150412 T6215 Tungaloy turning insert designed for ISO‑standard external and internal turning, suitable for stable to lightly interrupted cuts in stainless steel

• DNMG150412 insert, ISO rhombic
• CVD-coated carbide T6215 for stainless steel
• Double-sided chipbreaker, cylindrical hole

Consistent tool life through CVD-coated carbide technology

The CVD‑coated carbide grade T6215 combines a hard, wear‑resistant surface with a substrate engineered for toughness, delivering extended edge life when machining stainless steel under stable conditions. The CVD‑coating reduces abrasive wear and helps maintain a consistent cutting geometry, which in turn minimises rework and tool changes. For production environments seeking predictable cycle times, this wear behaviour supports higher productive uptime and fewer interruptions for tool replacement.

ISO geometry for reliable clamping and repeatable results

The rhombic insert follows ISO specifications and features a 55° cutting angle, a 1.2 mm corner radius and a 4.76 mm plate thickness, ensuring compatibility with a wide range of holders when form, clearance angle and tolerance class match. The central cylindrical hole secures the insert in the pocket and supports repeatable seating, which is essential for maintaining concentricity during external and internal turning. Specified geometry reduces setup variance and simplifies tool management across batches.

Efficient chip control and economical double‑sided use

Equipped with a double‑sided chipbreaker, the insert provides controlled chip formation for improved surface finish and safer swarf management. Two usable cutting edges extend the life per insert and reduce tooling costs per part, contributing to a more favourable total cost of ownership. The chip control characteristics also lower the likelihood of built‑up edge formation when machining stainless steels, helping to preserve dimensional accuracy and minimise secondary operations.

Practical machining guidance for stable performance

Best results are achieved with a stable tool overhang and a rigid setup; the grade is optimised for steady to lightly interrupted cuts rather than heavily interrupted conditions. Selecting appropriate cutting speeds and feed rates for stainless steel, together with the right coolant application, will balance wear resistance and thermal loading to deliver consistent surface quality. The insert integrates into a system comprising an ISO‑compatible holder or boring bar, clamp set and replacement screws to form an efficient turning solution.

FAQ

What materials is this insert suitable for?
The Tungaloy DNMG150412 T6215 insert is designed primarily for machining stainless steel under stable to lightly interrupted cutting conditions.

How does the double‑sided design affect cost efficiency?
Double‑sided geometry provides two usable cutting edges per index, so the DNMG150412 T6215 insert yields better cost per cutting edge and reduces tool change frequency.

Is the insert compatible with standard ISO holders?
Yes, the insert follows ISO specifications; compatibility with a holder depends on matching insert form, clearance angle, tolerance class, fixation method, size and thickness.

What are the key dimensions to check for holder selection?
Check the 15 mm size, 4.76 mm thickness, 1.2 mm corner radius and the 55° cutting angle when selecting a suitable holder for this insert.

Does the grade require special cooling or cutting strategies?
Standard coolant application and stable setup are recommended; the CVD coating is optimised for wear resistance so balancing speed and feed for stainless steel is important to avoid thermal softening.
