SPMN 120308 NS9530 indexable insert for turning — Tungaloy finishing grade

SPMN 120308 NS9530 is an ISO-designation indexable insert for turning, engineered as a finishing grade for steel applications with a square form and 90° included angle

• Uncoated cermet NS9530 finishing grade
• Sharp cutting edge for low cutting forces
• Square 12 mm insert, 0.8 mm corner radius
• 11° relief angle for standard ISO holders

Precision surface quality for finishing operations

The NS9530 uncoated cermet grade is formulated for finishing steel with a consistently sharp cutting edge, enabling markedly low cutting forces and improved workpiece integrity. This combination reduces vibration and helps achieve a high surface finish on parts where final dimensional quality and appearance matter. The insert's geometry supports stable, continuous cutting and is particularly suitable for small depth-of-cut finishing passes.

Designed for reliable fit and straightforward holder selection

Compatibility with toolholders depends on insert form, 11° relief, tolerance class, attachment method, size and thickness. The square 12 mm format and 90° included angle make integration into common ISO turning holders straightforward, provided the holder matches these dimensions and clamping style. Clear specification of the insert's form and relief simplifies setup and reduces changeover time in production environments.

Operational advantages in continuous cutting and light finishing cuts

With a corner radius 0.8 mm, the insert balances edge strength and fine profile control, which supports continuous cut regimes and small depths of cut typical for finishing operations. The uncoated cermet composition promotes a clean, defined cutting edge that maintains stability under the gentle cutting forces required for high-quality finishes, helping to extend effective tool life for finishing passes.

Practical benefits for workshop productivity and process control

Using an ISO-standard insert such as this supports repeatable results across machines and toolholders, contributing to process reliability. The clear, standardised geometry facilitates tool inventory management and rapid replacement, while the material and grade selection target predictable chip formation and surface quality when machining steel under controlled finishing conditions.
