CPGT 080202 NS9530 Wendeplatten - Tungaloy

Combining the sharp edge of the NS9530 uncoated cermet grade with a 0.2 mm nose radius and an 11° relief angle ensures low cutting forces, superior surface finish and consistent performance in finishing cuts on steel; order this insert directly via Metav Werkzeuge or consult our specialists for application support.

CPGT 080202 NS9530 turning insert – uncoated cermet, rhombic 80° (Tungaloy)

CPGT 080202 NS9530 is an ISO rhombic turning insert designed for finishing operations in external and internal turning, optimised for continuous cuts and small depths of cut.

• Uncoated cermet grade NS9530
• 0.2 mm nose radius for fine surface finish
• Rhombic ISO form CPGT 080202
• Single-sided chipbreaker for finishing

High finishing performance for steel and productivity gains

The insert is engineered as a finishing grade for steel, delivering a combination of a very sharp cutting edge and low cutting forces. The NS9530 uncoated cermet substrate promotes a fine surface quality in continuous cutting conditions, making it particularly suitable where a superior finish and tight tolerances are required. Reduced cutting forces lower spindle loads and enable stable cutting at small depths of cut, which contributes to more predictable cycle times and an optimised production flow. Benefit statements are backed by the insert’s geometry: the 0.2 mm nose radius produces consistently small scallop heights while the sharp cermet edge reduces built-up edge formation on most steels.

Precise geometry and reliable holder compatibility

The ISO rhombic form and dimensional specifications ensure compatibility with standard indexable turning systems when matching is performed correctly. Compatibility to a holder is determined by form, relief angle, tolerance class, clamping and plate thickness; the insert’s 11° relief angle and 2.38 mm thickness are specified to fit corresponding ISO clamping systems. The product includes a cylindrical hole with a single-sided countersink (40°–60°), which provides repeatable clamping seating and simplifies repositioning during index changes. Using inserts with matching form and tolerance class reduces setup time and helps maintain consistent cutting conditions across repetitive operations.

Material insight and recommended application approach

The insert combines a carbide substrate body with an uncoated cermet cutting grade, optimised for finishing steel in turning. Cermet materials offer a hard, wear-resistant cutting edge and a tendency to deliver enhanced surface quality compared with many coated grades in finishing operations. Because the grade is designed for continuous feeds and small depths of cut, it is advised to select cutting parameters that avoid interrupted cuts and heavy feed spikes. The single-sided chipbreaker supports controlled chip formation in finishing ranges; for heavy or interrupted cuts, alternative chipbreakers or grades should be considered. Overall, the geometry and NS9530 grade deliver a balance of surface quality and tool life for precision turning tasks.
