DNMG150408 T5115 ISO turning insert — CVD-coated carbide for cast-iron (Tungaloy)

The DNMG150408 T5115 is a CVD-coated carbide turning insert designed for external and internal turning, optimised for cast-iron machining with a 55° rhombic geometry.

• CVD-coated carbide grade T5115
• ISO-standard rhombic insert geometry
• Double-sided chipbreaker for stable cutting
• Cylindrical hole for secure clamping

Productive turning for cast-iron components

The combination of a CVD-coated carbide substrate and the T5115 grade provides a balanced mix of wear resistance and cutting-edge stability, designed specifically for machining cast iron. The coating reduces adhesion and flank wear, which translates into extended tool life and fewer indexings per component. For production environments where cycle time and repeatability matter, this insert supports higher cutting volumes without sacrificing surface finish.

Geometry and clamping that improve process reliability

A 55° rhombic plate form with a corner radius of 0.8 mm and a cylindrical locating hole allows reliable seating in ISO-compatible holders and repeatable positioning. The 0° relief angle and standard plate thickness of 4.76 mm contribute to stiffness and vibration damping, reducing edge chipping during interrupted cuts. Stable clamping and consistent geometry help maintain tolerances in series production and reduce scrap rates.

Chip control and practical advantages on the shop floor

The double-sided chipbreaker design supports predictable chip formation across a range of feeds and depths, simplifying process parameter selection. In combination with the universal T5115 grade, this results in fewer built-up edges when turning grey and nodular cast irons. The insert’s two usable cutting edges extend the service interval before replacement, improving overall tool utilisation in batch and continuous operations.

Material and coating explained for informed selection

The insert is made from carbide with a CVD coating, a proven combination for abrasive cast-iron alloys. CVD coatings form a hard surface layer that resists abrasive wear while preserving a robust cutting edge underneath; this balance is particularly beneficial when machining cast-iron components with varied microstructures. When selecting tooling for specific cast-iron grades, pairing the T5115 insert with a suitable holder and stable machine setup yields the best economy and surface quality.
