CPMT 090304 NS9530 indexable turning insert — Tungaloy

The CPMT090304 NS9530 ISO-standard indexable insert is designed for external and internal turning, offering a finishing grade optimised for steel with a rhombic 09 form.

• Finishing grade NS9530 for steel
• Uncoated cermet for superior surface finish
• Sharp edge for low cutting forces
• Rhombic 09 with 0.4 mm corner radius

Finish quality and process efficiency

The insert is engineered as an ISO-standard finishing solution that reduces secondary operations by delivering a consistent surface finish. The uncoated cermet composition promotes reduced built-up edge and maintains a sharp cutting edge, which results in lower cutting forces and less heat generation during continuous cuts. This combination supports shorter cycle times and fewer grinding or polishing steps, contributing to measurable productivity gains on batch and single-part runs.

Compatibility and secure clamping for reliable results

Compatibility with holders is determined by form, relief angle, tolerance class, fastening style, size and thickness; the insert is supplied with a cylindrical hole and a one-sided countersink (40°–60°) for secure mounting. The rhombic 09 geometry and the 11° clearance angle are optimised for standard external holders and boring bars, enabling stable clamping and repeatable positioning. Clear identification of holder type and clamping set ensures correct assembly and consistent cutting conditions.

Chip control and application-specific advantages

A single-sided chipbreaker tailored to finishing cuts improves chip formation under small depths of cut and continuous feed conditions. The modest 0.4 mm corner radius minimises cutting forces while preserving edge strength, making the insert particularly suitable where surface integrity is paramount. For customers requiring high-quality finishing on steel components, the combination of uncoated cermet and a precisely ground edge reduces the need for rework and helps achieve tighter surface-tolerance budgets.

Practical notes for process planners and buyers

The insert is part of a system comprising the ISO turning insert, a matching external holder or boring bar, a shim/clamping set and spare screws; correct pairing is essential for achieving the promised surface results. Given the finishing orientation of the grade, the insert is recommended for continuous cuts and small depths of cut rather than heavy roughing. Technical advisors can provide guidance on feed, speed and holder selection to align the component design with the insert’s strengths.

FAQ

What materials is this insert intended for?
The CPMT090304 NS9530 Tungaloy insert is a finishing grade developed for steel and is optimised for continuous cuts and small depths of cut.

What is the cutting material and how does it help?
The insert uses an uncoated cermet cutting material; this composition supports a sharp cutting edge and improved surface finish while reducing built-up edge during finishing operations.

Which holders and mounting are required?
Compatibility depends on holder form, relief angle, tolerance and fastening; the insert features a cylindrical hole with a one-sided countersink (40°–60°) for standard clamping sets and external holders.

What are the key geometry parameters to consider?
Important numeric parameters are 3.18 mm thickness, 11° clearance angle, 80° included angle and a 0.4 mm corner radius for the rhombic 09 geometry.

Is this insert suitable for interrupted cuts or roughing?
The NS9530 grade is specified as a finishing sort for steel and performs best in continuous cutting and small depths of cut; for heavy interrupted cuts or roughing, a different grade should be considered.
