TNMG 160412 NS9530 Tungaloy indexable insert for turning (60°, 1.2 mm radius)

TNMG160412 NS9530 Tungaloy is an ISO indexable turning insert engineered for finishing operations on steel and similar materials

• ISO triangular insert TNMG 160412 for turning
• NS9530 cermet grade for fine finishing
• 1.2 mm corner radius for superior surface finish
• Double-sided chipbreaker, cylindrical hole design

Precision finishing with a cermet grade built for low cutting forces

The NS9530 grade is an uncoated cermet formulated as a finishing grade for steel, delivering a sharp cutting edge and low cutting forces that translate into improved surface quality and reduced rework. In continuous cutting and small-depth finishing passes the combination of the cermet edge geometry and the fine grade chemistry reduces built-up edge and supports stable machining conditions. As a result, cycle-time consistency and part quality improve, particularly where tolerance and surface finish are decisive.

Geometry and system compatibility that ensure predictable clamping and stability

This triangular insert features a nominal size of 16 mm, a plate thickness of 4.76 mm and an included angle of 60°, with a 1.2 mm corner radius and a 0° clearance angle. The insert is supplied with a cylindrical hole for secure fastening and a double-sided chipbreaker, enabling indexable use on both faces. Compatibility with the toolholder depends on insert form, clearance angle, tolerance class, fastening method, size and thickness; the machining system typically comprises the ISO insert, a matching external holder or boring bar, a shim/clamping set and replacement screws. These geometric parameters yield a repeatable seating position and predictable cutting behaviour during finishing passes.

Practical applications and selection guidance for efficient turning

Designed primarily for turning, the indexable insert is well suited to both external and internal finishing operations on steel where surface integrity matters. The double-sided chipbreaker supports chip control in continuous chip flows while the fine cermet grade keeps cutting forces low at small depths of cut. For best results choose a compatible holder that secures the insert without micro-movement and match the chipbreaker and grade to the feed and depth of cut. When switching from roughing to finishing, the sharp edge and cermet wear characteristics of this insert reduce the need for secondary finishing, improving throughput and part consistency.

FAQ

What materials is this insert intended for?
The TNMG160412 NS9530 insert is formulated as a finishing grade for steel and similar ferrous materials; the NS9530 cermet provides low cutting forces and a sharp edge suited to fine turning.

Can this insert be indexed and reused?
Yes, the TNMG160412 NS9530 is double-sided and designed for indexing; the double-sided chipbreaker and cylindrical hole enable controlled reseating and extended usage.

Which geometry features influence holder selection?
Holder selection should consider the 60° included angle, 0° clearance angle, insert thickness 4.76 mm and size 16 mm to ensure correct seating and clamping for stable finishing cuts.

Is the TNMG160412 NS9530 suitable for internal turning?
Yes, this ISO triangular insert is suitable for both external and internal turning where finishing quality and low cutting forces are required.

How does the 1.2 mm corner radius affect surface finish?
The 1.2 mm corner radius balances edge strength and surface definition; it helps achieve a high surface finish while maintaining edge robustness in finishing passes.
