DNMG 150612 NS9530 turning insert — Tungaloy (55° rhombic, cermet finishing)

DNMG 150612 NS9530 is an ISO-format indexable turning insert designed for finishing steel in turning operations, offering a sharp uncoated cermet grade for low cutting forces and excellent surface quality

• DNMG 150612 ISO rhombic 55° geometry
• NS9530 uncoated cermet finishing grade
• Sharp cutting edge for low cutting forces
• Double-sided chipbreaker with cylindrical hole

Consistent surface finish with a finishing-grade cermet

The NS9530 grade is an uncoated cermet developed for finishing cuts in steel, delivering a sharp cutting edge and reduced built-up edge. For continuous cuts and small depths of cut, this composition lowers cutting forces and helps achieve a finer surface texture than typical carbide grades. The result is a measurable reduction in rework and fewer passes to reach tolerance, which supports a more predictable production flow and improved part quality.

Predictable geometry and secure clamping for repeatable results

The rhombic 55° geometry provides a stable cutting orientation for external and internal turning, while the 1.2 mm corner radius balances edge strength with the ability to produce fine contours. The insert is double-sided and features a cylindrical hole for positive seating in compatible holders; indexing the plate doubles the usable life per insert. Compatibility with a holder depends on form, relief angle, tolerance class, fastening, size and thickness, so matching the insert to the correct clamping system ensures predictable machining and reduced setup time.

Process efficiency through sensible system integration

This ISO-format insert is part of a system comprising the insert, an appropriate external holder or boring bar, a seating pad/clamp set and replacement screws. Selecting the correct chipbreaker and grade for the workpiece, machining mode and stability improves chip control and tool life. For finishing operations on steel, the uncoated cermet option reduces friction at the cutting edge, which supports consistent cycle times and may reduce the need for frequent tool changes—benefits that contribute directly to throughput and cost-efficiency.

Application guidance and practical recommendations

Intended primarily for turning steel in finishing regimes, the insert suits operations with small feeds and continuous cuts where surface quality is decisive. The plate’s ISO DNMG format allows easy integration into standard toolholding systems; the 0° relief angle and 6.35 mm plate thickness support secure clamping and stable cutting. Choose the double-sided chipbreaker and the NS9530 grade when prioritising surface integrity and low cutting forces under steady-cutting conditions.

FAQ

What types of turning are suitable for this insert?
The DNMG 150612 NS9530 turning insert is designed for external and internal turning in finishing operations, particularly continuous cuts on steel where surface quality is critical.

Is the NS9530 grade coated or uncoated?
The NS9530 grade used in the DNMG 150612 insert is an uncoated cermet, chosen for its sharp edge and low cutting forces during finishing.

Can the insert be indexed to use both sides?
Yes, the insert is double-sided with a cylindrical hole, allowing indexing to use the second cutting edge and thereby extend productivity per insert.

Which workpiece materials are recommended?
This insert is optimised for steel finishing; select the NS9530 grade and the appropriate chipbreaker for best results under small depths of cut and continuous cutting conditions.

How does the geometry influence holder compatibility?
Compatibility depends on form, relief angle, tolerance class, fastening, size and thickness—ensuring the holder matches these parameters secures correct seating and reliable cutting performance.
