DCGT 070204 NS9530 ISO turning insert for finishing – Tungaloy

DCGT 070204 NS9530 is an ISO rhombic indexable insert optimised for finishing operations on steel, offering a sharp cutting edge and stable chip control for continuous turning.

• ISO-compatible rhombic insert for standard holders
• Uncoated cermet grade NS9530 for fine finishes
• 0.4 mm corner radius for precise edge definition
• Single-sided chipbreaker for continuous cuts

Consistently superior surface quality with low cutting forces

The uncoated cermet grade NS9530 is formulated as a finishing grade for steel, delivering a sharp cutting edge and reduced cutting forces. In practice this means fewer secondary finishing steps and a lower risk of built-up edge when performing continuous cuts with small depths of cut. The resulting surface finish is improved, which supports higher first-pass yields and reduces downstream processing time in serial production.

Stable geometry for repeatable turning results

The rhombic DCGT geometry and defined parameters—0.4 mm corner radius, 7° relief angle and 55° included angle—provide predictable contact conditions with the workpiece. The plate thickness of 2.38 mm and the ISO 07 size ensure mechanical stability in standard external and internal holders when the correct clamp and underlay are used. These geometric properties translate into repeatable tool life and consistent component tolerances across batches.

Engineered for productive integration in machining systems

As part of the ISO turning insert family, the system approach relies on a matching holder, underlay and clamping set; compatibility is determined by form, relief angle, tolerance class, clamping and thickness. The single-sided chipbreaker improves chip control during continuous turning, reducing machine downtime for cleaning and enhancing process reliability. For production environments seeking steady cycle times, this combination supports a predictable, efficient workflow.

Recommended use and practical guidance for steels

This finishing grade is intended primarily for continuous turning of steel with small depths of cut and a focus on surface quality rather than heavy roughing. The insert includes a cylindrical hole with a one‑sided countersink (40°–60°) for secure clamping; ensure the selected holder matches the DCGT 07 form and the thickness specification.

FAQ

What is the primary application for this insert? The DCGT070204 NS9530 insert from Tungaloy is designed for finishing operations on steel, particularly continuous turning with small depths of cut to achieve high surface quality.

Is the NS9530 grade coated or uncoated? The NS9530 grade is an uncoated cermet, offering a very sharp cutting edge and low cutting forces, which benefits surface finish and dimensional stability.

Which holder characteristics must match the insert? Compatible holders must match the DCGT form, relief angle (7°), tolerance class, clamping method, plate size (07) and thickness (2.38 mm) to ensure secure seating and repeatable performance.

How does the chipbreaker affect machining? The single-sided chipbreaker is optimised for continuous cuts; it improves chip control during finishing, reducing the risk of tangling and helping to safeguard workpiece surface quality.

Can this insert be used for internal turning? Yes, the insert is suitable for both external and internal turning provided the holder allows correct orientation and clamping for the DCGT 07 geometry.
