DNMG150412 T505 rhombic turning insert, 55°; Tungaloy

The DNMG150412 T505 is an ISO-standard rhombic indexable insert designed for efficient external and internal turning, optimised for economic cast-iron machining and compatible with standard external holders and boring bars

• ISO‑standard rhombic insert, 55° cutting angle
• CVD-coated carbide grade T505 for cast iron
• Double-sided chipbreaker, cylindrical hole design
• 1.2 mm corner radius, plate thickness 4.76 mm

Productivity through optimised grade and geometry

The insert is manufactured from carbide with a CVD-coated surface in grade T505, which is tuned for the economic machining of cast iron. This combination delivers stable cutting behaviour and extended tool life in serial production. The 55° cutting angle in the rhombic geometry reduces radial cutting forces, enabling predictable chip formation and consistent dimensional results—benefits that reduce downtime and support throughput in turning operations.

Reliability and fit for purpose in the tool system

Compatibility is governed by insert shape, clearance angle, tolerance class, fixing, size and thickness. The DNMG150412 T505 features a cylindrical hole and standard form that ensures secure clamping in appropriate external holders or boring bars. The double-sided design offers two indexable cutting edges per side, which supports economical use and quick edge changes. Clear indications of plate size and thickness assist in selecting the correct clamping and replacement hardware for reliable performance.

Controlled chipbreaking and application guidance

A double-sided chipbreaker tailored to cast-iron applications helps to control chips during interrupted and continuous cuts, improving surface finish and evacuation from the cutting zone. The 1.2 mm corner radius provides a balance between edge strength and feed flexibility, making the insert suitable for finishing and light roughing passes where edge stability and surface integrity are priorities. Select holder rigidity and cutting parameters according to part stability to fully exploit the insert’s productive potential.
