DNMG150408 NS9530 turning insert — finishing for steel (Tungaloy)

DNMG150408 NS9530 is an ISO‑standard turning insert designed for finishing operations on steel, offering a sharp cutting edge and low cutting forces for continuous, fine‑feed turning.

• ISO‑standard DNMG form for universal holders
• Uncoated cermet grade NS9530 for finishing
• Sharp cutting edge for superior surface finish

Consistent finishing with an uncoated cermet for low cutting forces

The DNMG150408 is an ISO‑normed, rhombic turning insert made in the uncoated cermet grade NS9530, designed specifically for finishing cuts on steel. The sharp cutting edge reduces cutting forces, which lowers heat generation and helps to maintain dimensional accuracy during continuous cuts. The small 0.8 mm nose radius balances edge strength with the ability to achieve a fine surface finish, while the 55° wedge angle provides predictable chip flow and stable turning behaviour. For shops seeking repeatable, high‑quality external or internal turning results, this grade offers measurable improvements in finish and reduced need for secondary polishing.

Simple integration into standard tool systems and clear compatibility criteria

Compatibility with holders is determined by form, relief angle, tolerance class, clamping method, size and plate thickness; the DNMG150408 has a 0° relief angle, a 4.76 mm plate thickness and comes with a cylindrical hole for secure clamping in standard DNMG‑type external holders or boring bars. The insert is double‑sided with a chipbreaker on both faces, enabling economical indexable use. When specifying a holder set, confirm seat geometry and screw or clamp type to ensure correct seating and repeatable tool position. A correct tool‑holder match reduces chatter and prolongs both insert and toolholder life.

Practical selection tips and machining guidance for finishing steel

Choose the NS9530 grade and its double‑sided chipbreaker for continuous cuts and small depths of cut; the grade excels at producing high‑quality surfaces with low cutting forces. Avoid heavy interrupted cuts and excessive feed rates that overload the sharp edge—this insert is optimised for fine feeds and steady cutting conditions. If switching from coated carbide, expect improved surface integrity at finishing parameters; adjust speeds and feeds conservatively when first testing the grade. Use coolant or MQL according to machine and workpiece requirements to aid chip evacuation and thermal control.

FAQ

What machining tasks suit this insert best? This insert is designed for finishing operations in turning; the DNMG150408 NS9530 Tungaloy turning insert achieves low cutting forces and a high surface quality on steel during continuous cuts.

Is the insert compatible with standard DNMG holders? Yes, compatibility is achieved when holder seat geometry, clamp type and the insert's 0° relief, size and thickness are matched to the DNMG150408 form and ISO tolerances.

How many usable edges does the insert provide? The DNMG150408 is double‑sided with a chipbreaker on both faces, allowing multiple indexed cutting edges before replacement is required.

What workpiece materials are recommended? The NS9530 grade is optimised for finishing on steel; the cutting grade and sharp edge suit continuous steel turning with small depths of cut.

Which feature most improves surface finish? The combination of the sharp cutting edge, the 0.8 mm nose radius and the uncoated cermet NS9530 grade contributes most to achieving consistent high‑quality surface finishes.
