TNMG220404 NS9530 ISO indexable turning insert by Tungaloy — 60° triangle, 0.4 mm corner radius

A TNMG220404 NS9530 insert designed for finishing turns in steel, offering a sharp cutting edge and low cutting forces for continuous cuts and high surface quality

• ISO triangle insert TNMG 220404, 60° geometry
• Uncoated cermet grade NS9530 for fine finishing
• 0.4 mm corner radius for superior surface finish
• Double-sided insert with cylindrical hole for clamping

High-quality finishing for steel components

The uncoated cermet grade NS9530 was developed as a finishing grade for steel, combining a very sharp cutting edge with low cutting forces to produce consistently high surface quality. In practice, this means stable cutting at the low depths typical of finishing passes and reduced tendency for built-up edge on continuous cuts. The cermet substrate provides excellent wear resistance and leaves a fine surface without the need for additional coatings, making it particularly suitable where optical surface quality and dimensional tolerance are critical.

Reliable fit and secure clamping for production use

The insert follows the ISO indexable format and is supplied as a triangular insert with a 60° included angle, 0.4 mm corner radius and a 4.76 mm plate thickness. Compatibility with a chosen holder is determined by form, relief angle, tolerance class, fastening method, size and thickness; the cylindrical hole and double-sided geometry facilitate straightforward clamping and economical use of the cutting edges. Selecting the correct chipbreaker and grade according to the workpiece material and machine stability ensures repeatable results and minimises set-up time on the shop floor.

Economical machining and straightforward tool handling

Using a double-sided, indexable insert reduces tooling costs per edge and speeds tool changeovers; a typical system consists of the insert, a suitable external holder or toolbar, a shim or clamp set and replacement screws. The TNMG220404 design supports short interruptions between passes and is optimised for continuous finishing operations, improving throughput without compromising surface finish. For applications requiring predictable tool life and easy edge changes, this insert offers a balance of precision, economy and practical handling that supports steady production runs.

FAQ

What materials is this insert intended for?
The NS9530 grade is specified for finishing steel; the TNMG220404 insert is optimised for continuous turning of steel components where a fine surface finish is required.

How is the insert clamped in the toolholder?
Clamping is achieved via the central cylindrical hole and a compatible clamp or screw system; the triangular plate form and double-sided design support economical indexing and secure mounting.

What does the NS9530 designation mean for performance?
NS9530 denotes an uncoated cermet finishing grade with a sharp cutting edge, engineered for low cutting forces and high surface quality during finishing passes.

Can this insert be used for roughing operations?
This insert is primarily a finishing grade; for heavy roughing it is advisable to choose a grade and chipbreaker designed for higher depth of cut and greater toughness than NS9530.
