TNMG 160404 NS9530 Tungaloy turning insert — uncoated cermet for fine finishing, 60° triangle

TNMG 160404 NS9530 is a triangular ISO turning insert designed for finishing cuts in steel, offering a sharp edge and stable performance in continuous cutting applications.

• Uncoated cermet grade NS9530 for fine finishing
• Suitable for continuous cuts and light feeds
• ISO triangular insert, 60° with 0.4 mm radius
• Cylindrical hole with double-sided chipbreaker

Fine finishing with lower cutting forces and superior surface quality

The uncoated cermet grade NS9530 provides a sharp cutting edge tailored for finishing operations in steel, reducing cutting forces and enabling improved surface integrity. As a finishing grade, it is optimised for continuous cutting and small depths of cut, so operators can expect consistent dimensional accuracy and a reduced need for downstream grinding. The material choice and edge geometry translate into measurable productivity gains on long, uninterrupted turning passes.

Consistent fit and easy integration into ISO systems

Compatibility is determined by shape, clearance angle, tolerance class, clamping method, size and thickness; the ISO designation ensures direct interchangeability with standard holders. The insert is supplied with a cylindrical hole and is intended to be used with a matching outer holder or boring bar, plus shim/clamp sets and replacement screws as required. This standardised system design simplifies toolroom logistics and shortens setup times, which supports faster machine turnover and predictable process planning.

Geometry engineered for controlled chip formation and repeatability

The TNMG form with a 60° included angle and a 0.4 mm nose radius offers a balance between edge strength and the fine finish needed for precision components. The double-sided chipbreaker provides repeatable chip control on finishing passes while preserving the sharp edge. Because the insert is double-sided, indexable use extends tool life per insert, improving cost efficiency without sacrificing surface result or process stability.

Material and application guidance for reliable results

Manufactured from carbide substrate with an uncoated cermet cutting layer, this insert is specified as a finishing grade for steel components where low cutting forces and an excellent surface are required. The design is less suited for heavy interrupted cuts or high-feed roughing; instead, it excels when small material removal and controlled tool engagement are priorities. For best results, select a holder and cutting parameters that match the insert’s geometry and intended finishing role.
