DNMG110408 NS9530 — Tungaloy indexable turning insert for finishing (turning)

The DNMG110408 NS9530 is an ISO-format indexable turning insert designed for precision finishing of steel components, offering a sharp cutting edge, low cutting forces and excellent surface quality.

• Uncoated cermet NS9530 for fine finishing
• Sharp cutting edge for low cutting forces
• ISO DNMG 110408 rhombic insert, 55° lead angle
• Double-sided chipbreaker with cylindrical hole

Optimised finishing performance for steel

The insert is a finish-grade uncoated cermet developed to deliver a consistently superior surface on steel components. The NS9530 grade provides a very sharp cutting edge that reduces radial cutting forces, which in turn lowers the tendency for part deformation and vibration during light, continuous cuts. For production environments where repeatable surface quality and dimensional stability are priorities, this specification supports shorter finishing cycles and less downstream rework. The material choice—cemented carbide backing with a cermet cutting layer—combines edge strength with fine wear resistance, helping to maintain form and finish over multiple indexings.

Straightforward integration with ISO tooling systems

Compatibility with existing toolholders is governed by standardised characteristics: the rhombic DNMG 110408 form, 55° lead angle, 0° relief, plate thickness and fastening method. The insert features a cylindrical hole for secure clamping and a double-sided chipbreaker, enabling two usable cutting corners and predictable chip control in finishing cuts. Specifying this insert makes integration into established ISO DNMG holder systems simple and reliable, reducing setup time and inventory complexity for production shops that maintain ISO tooling families.

Process reliability and efficiency in the turning centre

Operational advantages focus on efficiency and predictable tool life: the insert’s geometry and cutting-edge integrity support low cutting forces, which lowers spindle load and can permit higher feedrates for equivalent finish targets. The double-sided design provides cost-effective reuse of the indexable corners, while the uncoated cermet surface is particularly effective in continuous cutting operations and small depths of cut where minimal burr formation and superior surface roughness are required. For manufacturers seeking stable, repeatable finishing with minimal adjustments, this combination delivers measurable process gains.

Practical selection and recommended use

Choose the DNMG110408 NS9530 when the application demands high surface quality on steel with small material removal per pass. The insert is optimised for continuous cuts and light finishing passes; it is less suited to heavy interrupted cuts or large depth-of-cut roughing operations. When selecting, match the insert to a compatible DNMG holder by checking form, relief angle, tolerance class, fastening method, size and thickness. Keeping a small stock of replacement screws and clamping sets simplifies changeovers and minimises downtime in production.

FAQ

Which materials is this insert intended for?
The DNMG110408 NS9530 is a finish-grade uncoated cermet optimised for machining steel in continuous finishing operations and small depths of cut.

Is the insert compatible with conventional DNMG holders?
Yes; compatibility depends on matching the DNMG form, lead angle, size, thickness and fastening method—this insert conforms to the ISO DNMG 110408 specification for straightforward use in standard holders.

How many edges are usable before disposal?
The insert is double-sided with two usable cutting edges per face; indexing provides multiple fresh edges until the tool reaches wear limits or edge damage.

What chip control does the insert provide?
Equipped with a double-sided chipbreaker, the insert delivers controlled chip formation for finishing cuts; the cylindrical hole supports secure clamping and stable cutting conditions.

Which cutting conditions are recommended for best surface finish?
For optimal results use light depths of cut with steady feed in continuous cutting; the sharp edge of the NS9530 grade reduces cutting forces and helps achieve a fine surface without excessive burr formation.
