DNMG150608 NS520 Tungaloy — ISO-indexable turning insert, cermet grade for finishing

DNMG150608 NS520 Tungaloy is an ISO-indexable rhombic turning insert designed for finishing to light turning of steel components, offering stable wear behaviour and high surface quality for precise production runs.

• ISO-standard rhombic insert, 55° geometry
• Cermet grade NS520 for fine surface finish
• 0.8 mm corner radius for precision turning
• Double-sided insert with cylindrical hole

Consistent surface quality and dimensional control for finishing work

The NS520 cermet grade is optimised for finishing to light turning of steel, providing a balanced combination of hardness and toughness that promotes uniform wear and a refined part finish. Cermets are characterised by a hard ceramic matrix with metal bonding, delivering superior surface finish and reduced built-up edge compared with conventional carbides. This results in improved dimensional control across series production, meaning fewer reworks and a more reliable final tolerance. The double-sided configuration further supports economy of use by offering additional indexable edges before replacement.

Secure seating and ISO-based compatibility to simplify tool selection

Built to ISO dimensions, the rhombic 55° geometry and the 0° relief angle ensure compatibility with standard DNMG holders when the form, clearance angle, tolerance class, fastening method, size and thickness match. The insert’s cylindrical hole provides positive location and reliable clamping with indexable holder systems, reducing the risk of seat movement under cutting forces. This standardisation speeds up tool changeover and lowers set-up variability, which benefits production flows that require repeatable accuracy.

Stable chip formation and process reliability for repeatable productivity

The insert’s double-sided chipbreaker design supports controlled chip formation during finishing cuts, helping to maintain process stability even when batch sizes increase. With the NS520 grade tuned to wear evenly, the component run maintains consistent surface quality over multiple tool indices. This predictability enhances machine uptime and operator confidence: choosing the correct chipbreaker and matching cutting parameters results in efficient material removal without sacrificing the required finish or tolerances.

Practical selection guidance for precise turning applications

For precision external and internal turning tasks, select an appropriate holder and clamp set suitable for the DNMG150608 geometry and the 6.35 mm plate thickness to ensure secure fixation. The 0.8 mm corner radius suits fine turning where a balance between edge strength and detail is needed—smaller radii support tighter radii features, while preserving edge life in finishing passes. If assistance is required in matching holder style, chipbreaker or cutting data, experienced technical advice is available to help specify the correct combination for the intended material and machining stability.
