DPMT 070204 NS9530 — Turning Insert (rhombic, 0.4 mm radius) by Tungaloy

A DPMT070204 NS9530 turning insert designed for finishing operations in steel turning, providing a sharp cutting edge and low cutting forces for consistent surface quality

• Uncoated cermet NS9530 for fine finishing
• Rhombic shape with 0.4 mm corner radius
• 11° relief angle for low cutting forces
• Central hole with cylindrical countersink 40°–60°

Consistent fine finishing with a cermet edge

This grade is an uncoated cermet (NS9530) developed for finishing of steel, delivering a sharp cutting edge and reduced cutting forces. The microstructure of the cermet helps achieve a superior surface finish on continuous cuts and small depths of cut, which reduces subsequent dressing or polishing steps. The combination of a small 0.4 mm corner radius and the specified relief geometry supports accurate profile reproduction and predictable component tolerances, making the insert particularly suitable where dimensional fidelity and surface integrity are priorities.

Secure clamping and ISO-standard compatibility for reliable set-up

The insert conforms to ISO dimensions and is compatible with matching ISO toolholders when form, relief angle, tolerance class, fastening, size and thickness are respected. The rhombic plate form and a plate thickness of 2.38 mm contribute to stable seating, while the central hole with cylindrical bore and one-sided countersink (40°–60°) ensures repeatable clamping and correct axial positioning. These features reduce setup variation and enable faster changeovers in production environments that rely on standardised tooling systems.

Productivity-focused design for finishing cycles

Engineered as a finishing grade with a one-sided chipbreaker, this insert excels in continuous turning operations where small feeds and fine cuts are used. The low cutting forces associated with the geometry and cutting material lower machine load and can extend toolholder life, supporting higher effective productivity per tool. Typical uses include both external and internal turning where consistent surface quality and minimal burr formation are required. The system approach includes the ISO insert together with a compatible outer holder or boring bar, a backing pad/clamp set and spare screws for an efficient replacement workflow.

FAQ

What materials is this insert intended for?
The DPMT070204 NS9530 is specified as a finishing grade for steel; the uncoated cermet substrate is optimised for continuous cuts and small depths of cut on steel components.

Is the insert compatible with standard ISO holders?
Yes — compliance with ISO dimensions means the insert fits ISO-compatible holders when form, relief angle, tolerance class, fastening method, size and thickness are matched.

How does the small corner radius affect the result?
A 0.4 mm corner radius delivers sharper profiles and improved surface quality for finishing passes while maintaining adequate strength for light interrupted cuts.

What role does the countersunk central hole play?
The central hole with a cylindrical bore and a 40°–60° countersink provides secure, repeatable clamping and correct axial orientation when used with matching screws and clamp sets.

For which types of turning is the chipbreaker suited?
The one-sided chipbreaker is designed for finishing applications where chip control supports stable, continuous cutting and consistent surface integrity.
