TPMN160308 NS740 indexable insert for turning by Tungaloy

TPMN160308 NS740 is an ISO-standard triangular indexable insert designed for finishing to light machining of steel, optimised for high surface quality and steady wear behaviour in precise turning operations.

• ISO-standard triangular insert, 60° geometry
• NS740 cermet for superior surface finish
• 0.8 mm corner radius for fine turning
• Compatible with ISO turning toolholders

Reliable finishing and consistent component quality

The NS740 grade is a cermet formulation tailored for finishing and light machining of steel, combining a hard ceramic phase with metallic binders to maintain a sharp cutting edge and reduce substrate adhesion. As an indexable insert, this component provides stable wear progression and repeatable dimensions across batches, which reduces regrinding cycles and inspection overhead. The result is improved first-pass accuracy and predictable tool-life economics when compared with standard grades.

Clear compatibility and secure clamping for productive setups

Compatibility with toolholders depends on the insert’s shape, clearance angle, tolerance class, clamping method, size and 3.18 mm thickness, which is consistent with ISO turning systems. The triangular, 60° geometry ensures secure seating in standard triangular pockets; the 11° clearance (free angle) supports effective chip flow and prevents rubbing on the flank. These design parameters simplify selection of a matching external holder or boring bar and reduce setup time on the shop floor.

Edge geometry and machining recommendations for superior finish

A 0.8 mm corner radius balances edge strength with the ability to achieve fine surface textures on turned parts. For finishing passes, reduced depths of cut and modest feed rates exploit the grade’s capabilities to deliver low roughness values and tight tolerances. The absence of an integrated chipbreaker on this insert suggests pairing with process parameters and coolant strategies that promote consistent chip formation; this approach supports stable cutting conditions and helps maintain component integrity.

Productivity gains and process reliability in daily production

Using an ISO-standard indexable insert with a predictable wear curve enables straightforward inventory handling and grade selection for specific operations. The triangular format gives three usable cutting corners per insert, which extends effective life per item and reduces tooling change frequency. Together with the grade’s focus on dimensional stability and surface finish, these attributes contribute to efficient, repeatable turning operations and lower overall machining costs in medium- to high-volume production.

FAQ

What materials is this insert suitable for?
The TPMN160308 NS740 indexable insert from Tungaloy is optimised for finishing and light machining of steel, where surface quality and dimensional control are priorities.

How is the insert mounted and what should be checked for compatibility?
Mounting requires a matching ISO triangular pocket; compatibility is determined by the insert’s shape, clearance angle, tolerance class, clamping method, size and thickness (3.18 mm).

What are the advantages of the NS740 cermet grade?
NS740 delivers a sharp edge and stable wear for superior surface finish and repeatable dimensional accuracy in finishing operations.

Does the insert include a chipbreaker?
This variant is supplied without a chipbreaker; machining strategy and coolant selection should be used to control chip formation.

How many cutting edges are available per insert and what is the corner radius?
The triangular design provides three usable cutting corners and a 0.8 mm corner radius suitable for fine turning.
