DNGG 110404 NS520 turning insert – Tungaloy

DNGG110404-01 delivers ISO‑standard indexable performance for external and internal turning, prioritising surface finish and dimensional stability.

• Cermet grade NS520 for fine finishing
• Rhombic 55° geometry for versatile turning
• 0.4 mm corner radius improves surface finish
• Cylindrical hole for secure mounting

Superior surface quality and repeatable accuracy

The combination of the NS520 grade and a cermet/coated cermet substrate is optimised for finishing and light machining of steel, delivering a consistent wear pattern and an improved surface texture compared with conventional carbide grades. The fine microstructure of the cutting material supports tight dimensional control and reduced burr formation, which in turn lowers post‑process rework. Where part tolerances and surface integrity matter, this grade enables stable process windows and predictable insert life.

Geometry engineered for productivity and stability

The rhombic plate form with a 55° approach angle and a 0° relief angle provides a balance between cutting edge strength and accessibility into profiles and shoulders. The 0.4 mm corner radius supports a superior surface finish without compromising edge life, while the 11 mm size and 4.76 mm thickness contribute to rigidity in both external holders and boring bars. These geometric choices reduce chatter risk and enable higher feed rates during finishing passes, improving throughput without sacrificing part quality.

System compatibility and secure clamping for reliable machining

Designed as an ISO indexable insert, compatibility with external holders is governed by shape, relief angle, tolerance class, clamping and thickness; the insert is supplied with a cylindrical hole for positive seating and repeatable indexing. Typical system setup comprises the ISO insert, a matched external holder or boring bar, a shim/clamp set and replacement screws—this modular approach simplifies inventory and changeover. The DNGG110404‑01 format ensures straightforward integration into existing turning systems, reducing setup time and improving process reliability.

FAQ

What applications is this insert best suited for? The DNGG110404‑01 NS520 Tungaloy indexable insert is tailored for finishing and light machining of steel in external and internal turning operations.

How does the NS520 grade affect surface finish? The NS520 cermet composition promotes a fine, uniform wear pattern and improved surface finish, helping to meet tight dimensional tolerances during finishing cycles.

Which holders are compatible with this insert? Compatibility is determined by the rhombic shape, 55° approach, 0° relief, thickness and clamping arrangement; use holders specified for DNGG110404‑01 formats.

Is the insert suitable for heavy roughing passes? The DNGG110404‑01 is optimised for finishing to light machining; for heavy roughing, a more robust grade or different geometry is recommended.

What is the correct way to secure the insert? Use the matching clamp/shim set and the designated screw size with the cylindrical hole to ensure repeatable seating and secure clamping of the insert.
