CPMT080208 NS9530 Tungaloy turning insert (uncoated cermet, 80° rhombic)

The CPMT080208 NS9530 is an ISO‑standard rhombic turning insert designed for finishing operations on steel, offering a sharp cutting edge and low cutting forces for excellent surface quality.

• ISO rhombic insert, 80° cutting angle
• Uncoated cermet grade NS9530 for finishing
• Sharp edge reduces cutting forces and improves finish
• Cylindrical hole with 40°–60° countersink for secure clamping

Achieve consistent, high-quality surface finishes with a finishing‑grade cermet

The insert is made in the NS9530 uncoated cermet grade and is optimised for finishing steel under continuous cutting conditions and small depth‑of‑cut passes. The fine, sharp cutting edge results in low cutting forces and a notably high surface finish, which reduces the need for secondary grinding or polishing operations. For shops prioritising consistent part quality, the combination of edge geometry and material composition supports repeatable results and less rework.

ISO compatibility simplifies tool selection and machine setup

Being an ISO‑standard insert, the geometry and dimensions are compatible with a wide range of holders when matched by shape, relief angle, tolerance class, fastening method, size and thickness. The plate’s 80° angle and 11° relief ensure predictable cutting engagement and clearance, while the 0.8 mm corner radius supports fine finishing without compromising edge strength. Specifying an ISO insert streamlines procurement and reduces tooling complexity across mixed fleets of lathes.

Secure mounting and controlled chip formation for more productive cycles

The insert features a single‑sided chipbreaker and a cylindrical hole with a one‑sided countersink (40°–60°), which together deliver reliable chip control and secure clamping. Stable chip evacuation lowers the risk of workpiece damage and reduces machine downtime, while robust fixation reduces micro‑movement at the cutting edge, preserving dimensional accuracy over longer runs. The system approach—insert plus appropriate external holder or boring bar, shim/clamp set and replacement screws—ensures safe, productive operation.

Material and grade selection that supports finishing strategies

As a finishing grade, NS9530 balances edge sharpness with wear resistance appropriate for steel components. The cermet composition maintains a crisp cutting edge that benefits soft to medium hardness steels under continuous feeds. This results in reduced burr formation and a cleaner part profile, enabling tighter tolerances without excessive feed reductions. For applications demanding higher metal removal, selection of a more robust grade or a coated alternative should be considered.

Practical applications and system considerations

The insert is suitable for both external and internal turning operations where fine surface integrity and low cutting forces are priorities. Typical setups pair the ISO insert with a suitable external holder or boring bar; ensure the holder matches the plate form, size and fastening style. For shallow finishing passes and profile work, the 0.8 mm radius and sharp edge deliver clear benefits in achieving final part specifications with fewer passes.

FAQ

What machining tasks is this insert best suited for?
The CPMT080208 NS9530 insert is intended primarily for finishing operations on steel where a high surface finish and low cutting forces are required; it is suitable for both external and internal turning.

How does the NS9530 grade affect cutting performance?
The NS9530 uncoated cermet provides a sharp cutting edge and good wear behaviour in continuous finishing applications, enabling improved surface quality and reduced burr formation compared with standard grades.

Can the insert be used in standard ISO holders?
Yes, the CPMT080208 is an ISO‑standard insert; compatibility depends on matching the holder’s form, relief angle, tolerance class, fastening method, size and thickness.

What clamping arrangement is required for secure mounting?
The insert uses a cylindrical hole with a one‑sided countersink (40°–60°) and is designed to be fixed with the appropriate clamp set and screws to ensure stable, vibration‑resistant mounting.
