DNMG110412 T6215 indexable turning insert — turning for stainless steels by Tungaloy

The DNMG110412 T6215 is an ISO-standard indexable turning insert designed for stable to lightly interrupted turning of stainless steels, offering a rhombic 55° geometry and a robust CVD-coated carbide grade for reliable performance.

• CVD-coated carbide for prolonged wear resistance
• 55° rhombic plate with 1.2 mm corner radius
• Double-sided chipbreaker for versatile turning
• ISO-compliant fit with cylindrical hole

Consistent wear resistance for demanding stainless-steel turning

The combination of a CVD coating and a wear-resistant carbide substrate ensures predictable flank and crater wear behaviour when machining stainless steels under stable cutting conditions. The selected grade is formulated for good adhesion of the coating and a balanced substrate toughness, which together reduce the frequency of insert changes and contribute to lower process costs over time. This technical design supports a continuous production flow by maintaining cutting performance and surface quality across long batch runs.

Geometry and edge preparation that improve surface finish and tool life

A 55° geometry with a 1.2 mm corner radius provides a stable cutting edge that distributes cutting forces and reduces cutting-edge chipping risk, especially in external and internal turning operations. The moderate corner radius helps to combine chip strength with a smooth surface finish, while the plate thickness of 4.76 mm contributes to rigidity in overhang situations. The rhombic plate form and double-sided chipbreaker enable two usable cutting edges per orientation, improving material utilisation and extending effective tool life.

System compatibility and practical machining advantages

Designed as part of an ISO-standard system, this insert locates via a cylindrical centre hole and mates with compatible external holders or boring bars; holder compatibility is determined by form, clearance angle, tolerance class, clamping method, size and thickness. The double-sided chipbreaker offers flexibility across a range of feeds and depths, simplifying process setup when switching between finishing and medium cutting tasks. Where intermittent cuts occur, the insert’s balanced substrate and coating combination deliver stable cut control and reproducible results in serial production. For technical clarification or holder recommendations, experienced advisers can support selection of the appropriate seating and clamping components.

FAQ

What materials is this insert suitable for?
The DNMG110412 T6215 turning insert is designed primarily for machining stainless steels under stable to lightly interrupted conditions; the CVD-coated carbide substrate provides wear resistance suitable for such applications.

How does the 55° geometry affect machining performance?
A 55° rhombic geometry reduces radial cutting forces and offers a compromise between access in internal turning and edge strength, helping to improve surface finish and stability during turning operations with the Tungaloy insert.

Can this insert be used on both external and internal turning applications?
Yes, the rhombic shape and the ISO-compliant fixation allow use in both external and internal turning setups when paired with the correct external holder or boring bar compatible with the DNMG110412 form.

How many cutting edges are available per insert?
The insert features a double-sided chipbreaker arrangement, providing multiple usable cutting edges and enabling economical indexation during production runs.

What information is needed to ensure holder compatibility?
Compatibility is determined by the insert form, clearance angle, tolerance class, clamping method, size and thickness; refer to the ISO designation DNMG110412 and the insert thickness of 4.76 mm when selecting an external holder.
