CPMT090308 NS9530 Tungaloy indexable turning insert — uncoated cermet, 0.8 mm corner radius

A CPMT090308 NS9530 Tungaloy indexable insert designed for precision external and internal turning of steel, optimised for fine finishing and continuous cuts.

• Uncoated cermet grade NS9530
• Sharp edge for superior surface finish
• 0.8 mm corner radius for fine turning
• ISO CPMT rhombic form, 11° clearance

Superior finishing performance for steel components

The NS9530 grade is an uncoated cermet designed specifically as a finishing grade for steel, delivering a sharp cutting edge and low cutting forces. This combination reduces workpiece deformation and enables consistently high surface finish, particularly in continuous cuts and shallow depths of cut. For machining where visual quality and dimensional tolerance matter, this geometry and grade minimise the need for secondary finishing operations.

Geometry and holder compatibility that simplify integration

The rhombic CPMT form (ISO 090308) with an included angle of 80°, 0.8 mm corner radius and 11° clearance ensures reliable seating and predictable contact with the toolholder. The insert thickness of 3.18 mm and the cylindrical hole with a single-side countersink (40°–60°) provide standardised clamping interfaces; compatibility with a chosen holder depends on form, clearance angle, tolerance class, fixing method, size and thickness. These standard features make retrofitting into existing ISO tooling systems straightforward and maintainable.

Process advantages and practical recommendations

Using a finishing cermet like this indexable insert offers reduced cutting forces, improved edge stability and enhanced wear resistance under continuous finishing conditions. The single-sided chipbreaker supports controlled chip flow for fine feeds; select the chipbreaker and grade to match the workpiece material and machining stability. For small depths of cut and smooth passes, maintain steady feed and avoid abrupt entry angles to preserve edge life and part quality. For application guidance or material-specific recommendations, consult Metav Werkzeuge for tailored cutting data and selection advice.

FAQ

What machining tasks is this insert best suited for?
This insert is optimised for finishing operations on steel; the NS9530 uncoated cermet grade on the CPMT090308 geometry suits continuous cuts and small depths of cut for high surface quality.

Can the CPMT090308 NS9530 be used for internal turning as well as external turning?
Yes, the rhombic CPMT form and the 0.8 mm corner radius allow the insert to be used for both external and internal turning where the holder and turning bar accept ISO CPMT inserts.

What are the key geometry features to check for holder compatibility?
Verify form, clearance angle (11°), tolerance class, fixing method, size (09) and thickness (3.18 mm) to ensure the insert correctly fits the intended toolholder.

How does the uncoated cermet grade affect tool life and surface finish?
The uncoated NS9530 cermet provides a sharp cutting edge and low cutting forces, giving excellent surface finishes; tool life is optimised for finishing conditions and may be shorter under heavy interrupted cuts.

Which SKU identifies this exact insert for ordering?
The insert is listed as CPMT090308 NS9530 by Tungaloy with SKU 6998451-Tungaloy (manufacturer article number 6998451).
