DNMG150404 NS9530 Tungaloy turning insert — uncoated cermet for finishing, rhombic 15 mm

The DNMG150404 NS9530 Tungaloy is an ISO rhombic turning insert designed for fine finishing of steel components in continuous cut conditions

• ISO rhombic insert DNMG 150404
• Uncoated cermet NS9530 for finishing
• 0° clearance for consistent contact
• Double-sided chipbreaker, with cylindrical hole

Consistent surface quality through low cutting forces

The uncoated cermet NS9530 offers a particularly sharp cutting edge and reduced cutting forces, which directly improves the achievable surface finish on steel parts. As a finishing grade, the material formulation is optimised for continuous cuts and small depths of cut, meaning fewer passes and less rework. The result is stable part tolerances and a reduction in downstream polishing or grinding, which supports a more economical production flow.

ISO compatibility and secure clamping for repeatable results

Built to ISO dimensions, the insert ensures predictable fit and function with standard holders: compatibility depends on form, relief angle, tolerance class, fastening, size and thickness. The rhombic geometry with a 55° main cutting angle and a corner radius of 0.4 mm provides a balance between fine edge definition and strength. The cylindrical hole and standard mounting arrangement give robust clamping and repeatable seating, which reduces setup variation and increases first-pass yield.

Productivity gains from chip control and neutral clearance

The double-sided chipbreaker is tailored to finishing cuts and aids controlled chip formation, improving tool life and machine uptime. With a 0° clearance the insert delivers a stable contact geometry that helps maintain a sharp edge under finishing conditions. Together, these features lead to more predictable cycle times and consistent part quality, supporting higher productivity on serial turning tasks.

Practical application and machining advice

Intended for external and internal turning of steel, the insert is best applied where continuous cutting and fine surface requirements dominate. Select the chipbreaker and grade to match workpiece material and machining stability; the cermet grade excels in low-force finish passes. When integrating into an existing toolset, verify the holder form and tolerance class to ensure correct seating and torque on the clamping screw.

Durability and handling considerations

Although specified as an uncoated cermet, the geometry and double-sided design allow economical indexing and straightforward stock management. The combination of a sharp edge and stable chip control reduces burr formation and the need for secondary operations. Handling precautions are standard for sharp carbide-based inserts: avoid dropping and ensure correct torque on the clamping screw to prevent micro-movement during high-speed finishing.

FAQ

What materials is this insert best suited for?
The DNMG150404 NS9530 insert is a finishing grade specifically for steel; the uncoated NS9530 cermet is optimised for continuous cuts and small depths of cut on steel components.

Can the insert be used for roughing operations?
This grade is designed as a finishing sort; for heavy roughing the DNMG150404 NS9530 insert may wear faster than grades intended for high material removal, so a tougher grade is recommended for roughing.

How is chip control achieved with this insert?
Chip control is provided by the double-sided chipbreaker integrated on the DNMG150404 NS9530, which supports consistent chip formation and reduced burrs in finish turning.

Is the insert indexable and economical to use?
Yes, the double-sided design allows indexing to a fresh edge, offering economical use per insert and straightforward stock management for serial production.

Which holders are compatible with the DNMG150404 NS9530?
Compatibility relies on matching the ISO form, relief angle, tolerance class, fastening method, size and thickness; use ISO DNMG-compatible external holders or boring bars and the correct shim/clamp set.
