TNGG 220404 NS9530 – Triangular turning insert (ISO 220404) by Tungaloy

A TNGG 220404 NS9530 triangular ISO indexable insert for turning, designed for fine finishing of steel with a sharp cutting edge and continuous-cut applications

• ISO triangular insert TNGG 220404 NS9530
• Uncoated cermet for fine finishing
• Sharp edge for low cutting forces
• Compatible with standard 22 mm holders

High-quality finish and reduced cutting forces for turning

The selection of the NS9530 uncoated cermet grade prioritises surface quality and low cutting resistance. As a finishing grade, it delivers a sharp cutting edge that lowers cutting forces and reduces built-up edge formation during continuous cuts, which results in consistently improved surface integrity. This makes the insert particularly suitable for operations where minimal tool-induced distortion and superior part appearance are required. The combination of the grade and geometry supports predictable tool behaviour under light feeds and shallow depths.

Geometry and system compatibility for reliable tool clamping

The insert is a triangular ISO 220404 type with a 60° included angle and a 0.4 mm corner radius, produced with a cylindrical hole for positive clamping. The plate thickness is 4.76 mm and the nominal size is 22 mm, with a 0° rake angle specified for stable cutting in finishing passes. Compatibility with a toolholder depends on form, clearance angle, tolerance class, fastening method, size and thickness; the complete system comprises the ISO insert, a matching external holder or boring bar, a supporting shim/clamping set and replacement screws. These defined interfaces enable secure seating and repeatable indexation, reducing setup time and variation between edges.

Application guidance and process benefits

Intended for external and internal turning, the insert features a double-sided chipbreaker that helps to control chip flow during steady-state finishes and light cross feeds. In practice, this results in fewer interruptions from long chips and more consistent cycle times in production runs. When paired with a properly selected holder and cutting parameters, the insert contributes to improved tool life and steady part quality. For batch manufacturing or precision components, the predictable performance of this geometry-grade combination supports process stability and a reduced need for in-process adjustments.

FAQ

What materials is this insert optimised for?
The NS9530 uncoated cermet grade is optimised for finishing operations in steel, offering a sharp edge and low cutting forces suitable for continuous cuts.

Is the insert compatible with standard ISO holders?
Compatibility is based on the insert form, size (22 mm), thickness (4.76 mm), hole style and tolerance; the TNGG220404 designation follows ISO standards for use with matching external holders and boring bars.

How many effective cutting edges are available per indexation?
As a double-sided triangular insert, the TNGG 220404 design provides multiple usable edges per indexation cycle before replacement is necessary.

Which applications benefit most from this grade and geometry?
Precision finishing tasks with light depths of cut and continuous feeds benefit most, where surface quality and low cutting resistance are priorities.
