CNMG090402 NS9530 Tungaloy indexable insert — ISO turning insert, uncoated cermet, 0.2 mm corner radius

A CNMG090402 NS9530 Tungaloy indexable insert designed for precision external and internal turning, optimised for fine finishing of steel components.

• ISO-standard rhomboid geometry for broad compatibility
• Uncoated cermet grade NS9530 for fine finishing
• 0.2 mm corner radius for precise surface control
• Double-sided insert with cylindrical hole for secure fixing

Consistent finishing and reliable cutting performance

The insert combines a cermet cutting grade with a sharp edge geometry to deliver low cutting forces and an excellent surface finish on steel. Cermet is a ceramic–metal composite that maintains a fine edge longer than many cemented carbides in finishing operations; this makes it particularly suitable for continuous cuts and small depths of cut where surface quality is the priority. The result is reduced rework and more predictable process outputs in series production.

Secure mounting and holder compatibility reduce setup time

Designed to ISO dimensions, the rhomboid shape and cylindrical hole ensure reliable clamping in standard turning holders. Compatibility is governed by form, relief angle and tolerance class, so the insert fits a wide range of external holders and boring bars when the correct seat and fastenings are used. The double-sided design doubles the usable life per index, improving cost-efficiency without complicating the tool change procedure.

Technical advantages for finishing operations

With a 0.2 mm corner radius and a relief angle of 0°, the geometry supports delicate engagement with the workpiece, lowering vibration and enabling consistent dimensional control. The uncoated NS9530 grade preserves a razor-sharp cutting edge that produces minimal built-up edge, which in turn helps to maintain tight surface roughness figures and repeatable part quality across batches.

Practical use and process guidance

The insert is best applied for turning operations where fine surfaces and low cutting forces are required. As an ISO-standardised component, it fits established tool systems and streamlines inventory management. For those unfamiliar with cermet characteristics, the main practical benefit is a longer edge retention in finishing, reducing the frequency of index changes and contributing to smoother workflows on the shop floor.
