DNMG150412 NS9530 turning insert — ISO rhombic finishing grade by Tungaloy

The DNMG150412 NS9530 is an ISO rhombic turning insert intended for finishing operations on steel, offering a sharp cutting edge, low cutting forces and excellent surface quality.

• ISO rhombic geometry, 55° cutting angle
• Uncoated cermet grade NS9530 for finishing
• Sharp cutting edge for high surface finish
• Double-sided insert with cylindrical hole

Achieve consistent finishing results with low cutting forces

The insert is engineered as an uncoated cermet grade optimised for finishing steel, delivering a sharp cutting edge and low cutting forces that reduce vibration and promote dimensional stability. These properties make the component particularly suitable for continuous cutting and small depth-of-cut operations, where surface quality and repeatability are critical. The reduced cutting resistance helps to extend tool life on light interruptions and supports predictable process windows in high-volume turning applications.

Compatibility and system setup for reliable clamping

Compatibility with the workholder is determined by the insert's form, clearance angle, tolerance class, fastening method, overall size and thickness. The ISO rhombic form with a 55° main angle enables access to turned profiles while the cylindrical locating hole supports positive seating and repeatable clamping. For a complete system, pair the insert with a suitable external holder or boring bar, plus the recommended shim/fastening set and replacement screws; correct matching ensures process stability and the best surface results.

Practical guidance for application and benefits at a glance

Choose this finishing grade when the priority is superior surface finish and low cutting forces rather than heavy metal removal. The double-sided design offers economical indexability, and the fine edge geometry reduces the need for secondary dressing. When machining steel with stable setups and modest feeds, expect improved part finish and consistent tolerances. For operators new to cermet grades: cermet combines ceramic and metallic phases to offer wear resistance with a fine edge, making it particularly effective in precision finishing tasks.

FAQ

What materials is this insert intended for?
The NS9530 finishing grade is specified for machining steel, where the DNMG150412 NS9530 Tungaloy turning insert yields low cutting forces and high surface quality.

Is the insert indexable on both sides?
Yes, the insert is double-sided; both cutting edges can be used before reindexing, improving economical usage.

How does the cermet grade affect surface finish?
Cermet materials offer a fine, wear-resistant edge; the NS9530 grade is tuned for high surface finish in finishing cuts under continuous cutting conditions.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the DNMG shape requires a matching rhombic external holder or boring bar with suitable screw/clamp geometry.
