DNMG150612 T6215 DNMG Turning Insert for Turning – Tungaloy

A DNMG150612 T6215 indexable turning insert engineered for external and internal turning of stainless steels, offering a CVD-coated carbide grade for extended wear resistance and stable chip control.

• CVD-coated carbide grade T6215
• Designed for stainless steel turning
• Rhombic DNMG shape, 55° cutting geometry
• Cylindrical hole and 6.35 mm plate thickness

Reliable wear resistance for demanding stainless steel operations

The CVD-coated T6215 grade combines a hard, wear-resistant coating with a tough carbide substrate to reduce flank wear and maintain cutting-edge integrity during repetitive turning. For materials prone to work hardening such as stainless steels, the coating improves thermal stability and lowers adhesion, which results in more consistent surface finish and longer intervals between index changes. The rhombic geometry with a 55° approach angle and 1.2 mm corner radius delivers a balance between strength and finish; the rounded corner reduces chipping risk while still supporting reasonable feed rates. This technical combination supports stable process windows in production environments.

ISO compatibility and secure clamping in industrial tool systems

The insert is manufactured to ISO dimensions and tolerances, making it compatible with a wide range of standard external holders and boring bars when matched by form, relief angle, tolerance class, clamping method, size and thickness. The cylindrical hole and 6.35 mm plate thickness ensure a positive, repeatable clamping interface that resists rotation and minimises micro-movements under load. A relief angle of 0° on the insert is part of the geometry specification and should be matched to the chosen holder and toolpath strategy. For reliable set-ups, pair the insert with the correct top clamping or screw system, a suitable shim or backing pad and spare screws as part of the system assembly.

Process reliability, chip control and system benefits

With a double-sided chipbreaker and a balanced geometry, the insert supports controlled chip formation and evacuation during both external and internal turning. This reduces the risk of built-up edge and chatter in stable to lightly interrupted cuts, contributing to predictable tool life and reduced machine downtime. The ISO plate format allows quick index changes and easy stock management, while the CVD coating helps preserve edge integrity across runs. For a complete solution, the system comprises the insert, a compatible holder, backing pad or clamping kit and replacement screws so that maintenance and reassembly remain straightforward on the shop floor.

FAQ

What materials is this insert suitable for?
The DNMG150612 T6215 insert is designed primarily for stainless steels and performs well under stable to lightly interrupted turning conditions thanks to the CVD-coated T6215 grade.

How does the insert’s geometry affect performance?
The rhombic DNMG shape with a 55° cutting geometry and 1.2 mm corner radius gives a compromise between edge strength and surface finish, reducing chipping while enabling reliable turning performance.

Is the insert compatible with standard holders?
Yes; the insert follows ISO dimensions, and compatibility depends on matching form, relief angle, tolerance class, clamping and plate thickness. The cylindrical hole and 6.35 mm thickness support secure clamping.

What system components are recommended for mounting?
A matched external holder or boring bar, backing pad or clamping set and the correct replacement screws are recommended to ensure stable mounting and repeatable results with this insert.

Can the insert be used for interrupted cuts?
The T6215 grade and geometry are suitable for stable to lightly interrupted conditions; heavily interrupted machining may require a different grade or a larger corner radius.
