CNMG 120404 NS9530 turning insert — finishing grade for Stahl by Tungaloy

A CNMG120404 NS9530 ISO turning insert engineered for high-quality finishing of Stahl components in continuous-cut regimes.

• ISO-standard rhombic insert CNMG120404
• Uncoated cermet grade NS9530 for finishing
• Sharp cutting edge reduces cutting forces
• Through-hole mounting, compatible with ISO holders

Consistent finishing quality with reduced cutting forces

The finishing grade is based on an uncoated cermet formulation (NS9530) that delivers a sharp cutting edge and sustained edge stability in light cutting depths. This results in low cutting forces and an improved surface finish on Stahl components, especially under continuous-cut conditions. The chemistry and microstructure of the cutting material are optimised for fine stock removal rather than heavy interrupted cuts, so the emphasis is on reproducible part quality and extended edge life during finishing passes.

Geometry and mounting that speed set-up and stability

The rhombic insert geometry with an 80° lead angle, 0° relief angle and a 0.4 mm corner radius provides predictable cutting behaviour and easy programme transfer between machines. The insert is double-sided with a through-hole, cylindrical mounting, enabling rapid indexing and secure clamping in standard ISO holders. The plate thickness of 4.76 mm and nominal size 12 mm contribute to mechanical stability while keeping the cutting-edge accessible for finely tuned turning cycles.

Practical process advantages for shopfloor productivity

Selecting the NS9530 finishing grade reduces rework and polishing effort, which shortens downstream handling times. The combination of ISO compliance, a defined corner radius and a sharp edge means stable chip formation and consistent dimensional control when used with appropriate feeds and speeds. Where surface quality and minimised cutting forces are priorities, this insert supports efficient cycle times and predictable tool-change intervals in production environments.

FAQ

What materials is this insert intended for?
The CNMG120404 NS9530 grade is designed primarily for finishing operations on Stahl, where a sharp edge and low cutting forces are required for high surface quality.

Can the insert be used in standard ISO holders?
Yes, the insert is an ISO-format rhombic plate with a through-hole and cylindrical style, intended for secure clamping in standard ISO turning holders.

How does the NS9530 grade differ from general-purpose grades?
NS9530 is an uncoated cermet finishing grade formulated to provide a sharp cutting edge and low cutting forces for continuous finishing cuts, offering superior surface finish compared with general-purpose carbide grades.

What are the key geometry values to consider for programming?
Key values include the 80° lead angle, 0° relief angle and 0.4 mm corner radius; these parameters affect engagement, chip flow and final surface finish during turning with the CNMG120404 insert.
