DNMG150408 T6215 Turning Insert — Tungaloy

DNMG150408 T6215 Tungaloy Turning Insert is a rhombic ISO turning insert designed for machining stainless steels under stable to slightly interrupted conditions

• CVD-coated carbide grade T6215
• For turning of stainless steels
• Rhombic DNMG 150408, 0.8 mm radius
• Double-sided chipbreaker, cylindrical hole
• 0° negative rake, 4.76 mm thickness

Consistent performance for stainless-steel turning

The CVD-coated carbide in grade T6215 offers high wear resistance specifically tuned for the demands of machining stainless steel. In practical terms this means longer tool life and fewer indexings during series production, resulting in improved productivity and lower tooling costs per component. The coating and substrate combination is optimised for stable to slightly interrupted cuts, reducing flank wear and maintaining a predictable cutting edge for repeatable surface finish.

Geometry and ISO compatibility that simplifies set-up

The rhombic DNMG150408 form with a 0.8 mm corner radius and 55° insert angle provides a balance between edge strength and accessibility for external and internal turning. Compatibility with ISO holders depends on form, clearance angle, tolerance class, fixing method, size and thickness — the insert’s 4.76 mm thickness and cylindrical hole ensure secure clamping in standard fixtures and easy replacement within conventional tool holders. This reduces set-up time and supports stable process parameters on conventional and CNC lathes.

Practical benefits from chip control and edge design

A double-sided chipbreaker tailored to the insert geometry helps to control chip form when machining stainless steels, lowering the risk of built-up edge and improving surface finish. The 0° negative rake increases edge robustness for interrupted cuts and heavy feeds, while the double cutting edges per side provide economical usage and straightforward indexing. Together these features enable higher metal removal rates where process stability allows, and a more reliable production rhythm in mixed-batch environments.

System integration and application guidance

This insert is part of a complete ISO turning system that includes the insert, a matching external holder or boring bar, underlay plates/clamps and replacement screws. Selection of the correct chipbreaker and grade should match workpiece material, machining strategy and machine stability; the T6215 grade is recommended for stainless steels under steady conditions. For mixed-material workshops, choosing the appropriate cutterhead and toolholder geometry will preserve cutting-edge life and maintain dimensional accuracy across batches.

FAQ

What materials is this insert suited for?
The DNMG150408 T6215 turning insert is optimised for stainless steel machining; the CVD-coated carbide grade T6215 provides wear resistance for stable to slightly interrupted turning operations.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm radius increases edge strength for interrupted cuts and improves surface integrity; it represents a compromise between tool robustness and the ability to produce defined radii on external and internal contours.

Is this insert compatible with standard ISO holders?
Yes, the DNMG150408 form is an ISO-standard insert; compatibility depends on form, clearance angle, tolerance class, fixing method, size and thickness — matching the insert’s 4.76 mm thickness and cylindrical hole to the holder is essential.

How many cutting edges are available per insert?
This is a double-sided DNMG insert with multiple usable edges; the double-sided chipbreaker design enables economical edge indexing and consistent chip control.

Which chipbreaker should be chosen for heavy feeds?
Select a chipbreaker and cutting parameters that match the workpiece stability and feed rate; the double-sided chipbreaker on this insert is suitable for a range of feeds, but heavier or unstable cuts may require a more robust holder setup.
