TNGG160404 NS520 triangular turning insert with 0° relief, Tungaloy

TNGG160404 NS520 is an ISO-format turning insert designed for finishing to light turning of steel components, optimised for surface quality and dimensional accuracy.

• NS520 cermet for finishing
• Triangular insert with cylindrical hole
• 0° relief for stable cutting
• Double-sided chipbreaker for even wear

Improved surface finish and dimensional control for finishing operations

The insert is made from cermet (NS520) bonded on a carbide substrate, a combination that prioritises a fine-grain edge and consistent wear behaviour. This results in significantly improved surface finish and tighter dimensional accuracy during finishing to light turning tasks. The small 0.4 mm corner radius helps maintain high-quality part edges while reducing the risk of chatter at modest feeds; for less experienced users, this means fewer scrap parts and more predictable production outcomes. The ISO geometry ensures that form, relief angle and tolerance classes align with standard holders, simplifying machine setup.

Reliable chip control and repeatable tool life for productivity

Equipped with a double-sided chipbreaker and a cylindrical hole for secure clamping, the insert supports stable chip formation and repeatable seating in the tool holder. The 0° relief specification delivers a consistent cutting engagement that favours low-vibration finishing cuts on steel, while the 4.76 mm plate thickness contributes to edge stability under moderate cutting forces. Together, these features increase process reliability and reduce tool-change frequency, which directly benefits throughput and lowers unit production time.

Compatibility and handling that simplify workshop routines

The insert follows the ISO turning insert family conventions, so compatibility with outer holders is determined by geometry, clearance, tolerance class, fixing and thickness rather than by special adapters. The triangular plate shape and 60° included angle permit multiple effective cutting edges per insert, aiding cost efficiency in serial operations. For straightforward integration, select the matching holder and clamping set; the insert’s design minimises alignment errors and eases indexable changeover during scheduled maintenance intervals.

FAQ

What materials is this insert suitable for?
The NS520-grade insert is designed primarily for machining steel and is optimised for finishing to light turning operations where surface quality and dimensional consistency are critical.

How does the NS520 grade affect productivity?
NS520’s cermet formulation supports stable wear and fine cutting edges, which enhances surface finish and extends effective tool life in finishing applications, reducing rework and increasing productivity.

Is the TNGG160404 compatible with standard ISO holders?
Yes. The TNGG160404 is an ISO-format indexable insert; holder compatibility depends on matching the insert form, relief angle, tolerance class, fixing and thickness.

Can the insert be used on both internal and external turning?
The insert is suitable for both internal and external turning operations, provided the correct holder and mounting arrangement are used for the intended machining setup.

How is chip control managed with this insert?
Chip control is achieved via the double-sided chipbreaker geometry, which promotes consistent chip formation and even wear across the cutting edges.
