DNMG150412 T515 Tungaloy indexable turning insert — CVD-coated carbide, 55°

DNMG150412 T515 is an ISO-standard indexable insert designed for economical external and internal turning, optimised for cast iron applications

• CVD-coated carbide for wear resistance and life
• Optimised for cast iron machining
• Rhombic DNMG 55° geometry with 1.2 mm radius
• Double-sided chipbreaker, cylindrical hole

Reliable performance for economical cast iron turning

The combination of a CVD-coated cutting surface and a hard carbide substrate in grade T515 offers a pragmatic balance between tool life and cutting efficiency. For cast iron operations, this composition delivers stable wear behaviour and consistent edge integrity during continuous and interrupted cuts. The CVD coating reduces flank wear and supports higher cutting speeds compared with uncoated grades, which translates into measurable productivity gains and more predictable tool-change intervals.

Secure clamping and proven ISO compatibility

Built to the ISO DNMG form, the insert features a 55° approach angle and a cylindrical hole to ensure positive seat location and repeatable clamping in compatible holders. The specified 0° clearance angle and the rhombic plate form provide versatility for both external and internal turning setups. Compatibility depends on holder form, tolerance class, fastening method, size and thickness, so the system approach — insert, holder, clamping set and replacement screws — is essential for process reliability.

Improved chip control and surface finish

The double-sided chipbreaker is optimised for chip formation in cast iron, reducing the risk of chip jamming and improving evacuation at moderate cutting speeds. A 1.2 mm corner radius supports a robust cutting edge for stable machining and contributes to a consistent surface finish while maintaining acceptable cutting forces. For applications requiring smoother faces, choosing the right combination of feed and radius helps balance component quality and tool life.

System advice and application scope

The insert is suitable for a wide range of turning tasks where cast iron is the primary workpiece material. Typical uses include external profiling, shoulder turning and light internal operations. For best results, select the chipbreaker and grade according to part stability, presence of interrupted cuts and the desired cutting speed. The insert is supplied as part of a system comprising the indexable insert, a matched external holder or boring bar, a support/shim and clamping hardware to guarantee consistent mounting and repeatability.

FAQ

What materials is this insert best suited for?
The DNMG150412 T515 insert with CVD-coated carbide substrate is optimised for machining cast iron and delivers stable wear behaviour and good chip control in that material.

How does the double-sided chipbreaker affect performance?
The double-sided chipbreaker on this insert improves chip control during continuous and interrupted cuts, reducing the likelihood of chip entanglement and supporting consistent surface quality.

Which holder types are compatible with this geometry?
Compatibility depends on holder form, fastening and tolerance class; the DNMG shape and cylindrical hole are designed for standard DNMG holders and matched boring bars that accept ISO DNMG inserts.

What advantages does the T515 grade provide compared with uncoated grades?
Grade T515 combines a wear-resistant CVD coating with a robust carbide substrate, offering longer edge life at elevated cutting speeds and improved process stability compared with uncoated equivalents.
