DNMG150412 T515 turning insert — ISO indexable turning insert by Tungaloy

The DNMG150412 T515 is an ISO-standard rhombic indexable insert designed for external and internal turning, optimised for economical machining of cast iron.

• CVD-coated T515 grade for cast iron machining
• Rhombic DNMG form with 55° cutting angle
• 1.2 mm corner radius with cylindrical hole

High process efficiency for cast-iron turning

The CVD-coated T515 grade is formulated for productive, cost-efficient machining of cast iron. The CVD coating on the carbide substrate reduces flank wear and supports consistent cutting conditions, which leads to longer tool life and fewer insert changes. For workshops aiming to increase throughput, the coated grade provides a measurable improvement in machining time per component while maintaining surface quality. Select the chipbreaker and grade combination according to the workpiece stability and the expected cutting speed to achieve the best economic result.

ISO compatibility and secure clamping for repeatable results

An ISO-standard geometry ensures the insert seats correctly in matched holders: form, relief angle, tolerance class, fixing method, size and thickness determine compatibility. The insert is supplied in the standard DNMG shape, with a 0° relief angle and a central locating feature, so it can be used with a broad range of ISO DNMG holders and boring bars. A properly matched holder and clamping assembly will transfer forces reliably, so the machining process remains stable and repeatable even under varying cutting conditions.

Robust edge geometry for surface finish and stability

The rhombic DNMG geometry with a 55° included angle and a 1.2 mm radius offers a balance between strength and finish. The insert’s dual-sided chipbreaker supports controlled chip formation and helps to avoid built-up edge when turning cast iron, while the cylindrical hole provides positive location and secure clamping. With a plate thickness of 4.76 mm and plate size 15 mm, the geometry contributes to edge robustness and predictable wear behaviour, supporting consistent component quality over long production runs.

Practical selection advice and typical applications

Designed for turning operations, the insert is suitable for both external and internal machining of cast-iron components where economy and surface integrity matter. For interrupted cuts or marginal workpiece support, choose a chipbreaker and cutting parameters that favour stability; in high-stability setups, higher cutting speeds can be exploited for faster cycle times. The insert integrates into a system comprising an ISO holder, shim/clamp and fixing screw; these system elements should be selected to match the insert geometry to secure optimal cutting performance.
