DNGG150408 150408 NS9530 DNGG turning insert — Tungaloy, uncoated cermet, 55°

DNGG150408 NS9530 is an ISO-format rhombic turning insert for finishing steel, optimised for continuous cuts and small depths of cut.

• Rhombic 55° geometry for versatile turning
• Uncoated cermet NS9530 for fine surface finish
• 0.8 mm corner radius for precise detail
• Double-sided chipbreaker, with cylindrical hole

High-precision finishing with low cutting forces

The insert is engineered as an uncoated cermet in grade NS9530, a finishing-grade substrate that combines a sharp cutting edge with reduced cutting forces. This composition improves stability during continuous turning and helps achieve a superior surface quality on steels. The material choice is particularly suited to operations requiring consistent finishes rather than heavy material removal; in practical terms, this means fewer reworks and shorter finishing cycles for production runs.

Stable geometry and reliable seating for consistent results

A defining mechanical characteristic is the rhombic 55° geometry, which provides a predictable cutting angle and good access to external and internal profiles. The insert features a 0.8 mm corner radius, supporting fine-detail machining without compromising edge strength. The insert is supplied in an ISO format that ensures compatibility with standard holders; correct fit depends on form, clearance angle, tolerance class, fixing method, size and thickness to guarantee repeatable clamping and accurate cutting performance.

Optimised chip control and application scope

Equipped with a double-sided chipbreaker and a cylindrical hole for secure fixing, the component supports controlled chip formation during finishing passes. The chipformer and grade selection are intended for steels processed with small depths of cut and continuous feed conditions; this reduces the likelihood of built-up edge and supports steady tool life. Where surface integrity and minimal cutting force are priorities, the combination of chip control and cermet edge geometry delivers measurable productivity gains.

Practical selection and machining advice

When selecting this insert for production, pair the insert with a suitable external holder or boring bar sized for ISO DNGG plates and verify the holder’s clearance and tolerance class. For finishing steel, apply moderate cutting speeds and consistent feeds to exploit the NS9530 grade’s advantage in surface finish. If a different workpiece material or heavier roughing passes are required, consider a different grade or geometry optimised for high removal rates rather than fine finishing.

FAQ

What materials is this insert intended for?
The DNGG150408 NS9530 insert is designed primarily for finishing operations on steel; the NS9530 cermet grade is optimised for low cutting forces and high surface quality when turning steel.

Can the insert be reversed or indexed?
Yes, the insert is double-sided with a chipbreaker on both faces, allowing multiple usable edges before replacement; correct indexing depends on holder compatibility and secure seating.

What does the NS9530 designation mean for machining?
NS9530 denotes an uncoated cermet grade with a sharp cutting edge suited to finishing applications; it promotes fine surface finishes and is best used with continuous feed and small depths of cut.

Which holders are compatible with ISO DNGG150408 inserts?
Compatibility is determined by the holder’s form, clearance angle, tolerance class, fixing method, size and insert thickness; choose holders specified for ISO DNGG-format plates to ensure accurate clamping.
