TNMG160408 NS9530 TNMG turning insert – uncoated cermet for finishing, Tungaloy

The TNMG160408 NS9530 is an ISO-standard triangular turning insert designed for external and internal turning, optimised as a finishing grade for steel with a sharp cutting edge and low cutting forces.

• ISO-standard triangular insert TNMG format
• Uncoated NS9530 cermet for fine finishing
• Double-sided chipbreaker for versatile use
• 0.8 mm corner radius with cylindrical hole

High-quality finishing with reduced cutting forces

The uncoated NS9530 cermet grade is formulated for fine finishing of steel: its sharp, stable cutting edge reduces cutting forces and promotes excellent surface quality in continuous cuts and small depths of cut. This makes the insert particularly suitable where dimensional accuracy and surface integrity matter. The cermet substrate combines wear resistance with a propensity for smooth chip formation, translating directly into fewer reworks and predictable process outcomes.

ISO compatibility and secure mounting for reliable production

Delivered in the ISO series for turning, the insert’s triangular TNMG160408 geometry and cylindrical hole ensure compatibility with standard external holders and boring bars. Compatibility depends on form, free angle and size; the TNMG form, a 60° included angle and a 0° free rake specification accommodate most standard ISO clamping systems. The double-sided configuration increases tool life and reduces tooling cost per part by allowing indexation on both cutting edges.

Design details that support everyday workshop efficiency

Key dimensions such as the 0.8 mm corner radius, 4.76 mm plate thickness and the 16 size designation give straightforward guidance for selecting holders and setting cutting parameters. The double-sided chipbreaker provides predictable chip control for finishing operations; combined with the uncoated cermet grade, it supports continuous cutting strategies with stable temperatures and consistent surface results. The insert forms part of a system that includes the ISO plate, a matching holder or boring bar, a shim/clip set and replacement screws, facilitating quick changeover and reduced downtime.

Select the right chipbreaker and grade for the task

For best results, pair this finishing insert with a holder and stability level suited to light to medium interrupted cuts. The uncoated NS9530 grade is optimised for low cutting forces and excellent surface finishes rather than heavy roughing: choose an alternative chipbreaker or a tougher grade if higher depths of cut or interrupted operations are required. This selective approach ensures process efficiency and extends tool life, supporting predictable machining cycles and fewer unplanned interventions.

FAQ

What materials is this insert best suited for? This finishing insert is optimised for steel machining; the NS9530 uncoated cermet grade delivers low cutting forces and high surface quality on continuous steel turning.

Can the insert be indexed to use multiple cutting edges? Yes, the triangular TNMG form is double-sided and can be indexed, allowing use of multiple cutting edges before replacement.

How does the cylindrical hole affect clamping? The cylindrical hole provides secure location in compatible ISO holders and supports precise repeatability during tool changes.

Is this insert suitable for roughing operations? The TNMG160408 NS9530 is a finishing grade; for heavy roughing or interrupted cuts a tougher grade or different chipbreaker should be selected.
