TPMN 110308 NS740 Wendeplatten - Tungaloy

The combination of the NS740 cermet grade and the ISO-standard TPMN110308 geometry ensures high-quality surface finish, predictable wear and economical use of three cutting edges; order the inserts directly via Metav Werkzeuge or consult their application specialists for machining data and tooling compatibility.

TPMN 110308 NS740 turning insert (ISO triangular, 0.8 mm) — Tungaloy

TPMN110308 NS740 is a triangular ISO turning insert engineered for finishing to light turning of steel, offering stable abrasion behaviour and reliable dimensional control.

• ISO-standard triangular insert for turning
• NS740 cermet grade for finishing
• 0.8 mm corner radius for fine edge control
• 11° relief angle for reliable seating

Precision finishing with consistent wear

The NS740 grade is a cermet formulation optimised for finishing and light machining of steel, combining hardness with thermal resistance to promote a uniform flank wear pattern. With a 0.8 mm corner radius and 11° relief angle, the geometry supports improved surface integrity and tighter tolerances while maintaining chip control during low-to-moderate feeds. The ISO-standard form guarantees interchangeability with compatible holders specified by form, tolerance class, clamping and thickness, simplifying tool setup and inventory management.

Flexible system compatibility and efficient edge use

Designed as an indexable triangular plate, the insert provides three cutting edges, which reduces tooling costs per edge and enhances uptime. The component thickness of 3.18 mm and the ISO designation determine the correct combination of holder, shim and clamping set for secure fixation. This version is supplied without chipbreaker, making it particularly suitable where uninterrupted cutting geometry yields superior surface finish; the absence of a chipbreaker also facilitates manual choice of cutting conditions or use of external chip control measures when required.

Application guidance and machining advantages

For external and internal turning operations the cermet substrate supports repeatable results when the process emphasises surface quality over heavy material removal. The triangular form and sharp edge preparation enable precise finishing passes, while the grade's wear characteristics extend edge life in light-duty applications. As with all indexable plates, selection of the matching insert grade and seat tolerance should follow the workpiece stability and machining strategy to achieve the intended balance of tool life and surface finish.

FAQ

What materials is this insert suited for?
The Tungaloy TPMN110308 NS740 is intended primarily for finishing and light machining of steel; the NS740 cermet grade emphasises surface quality and even wear for steel applications.

How many cutting edges are available per insert?
As a triangular plate, the insert provides three usable cutting edges, allowing efficient edge utilisation before indexation or replacement.

Is the TPMN110308 compatible with standard ISO turning holders?
Yes, the ISO-standard geometry of TPMN110308 determines compatibility by form, relief angle, tolerance class, clamping and thickness; match the holder accordingly.

What is the effect of the 0.8 mm corner radius?
The 0.8 mm corner radius improves edge strength for finishing passes and contributes to a finer surface finish while maintaining dimensional stability.

Does this insert include a chipbreaker?
This variant is supplied without chipbreaker, making it suitable where a plain cutting geometry is preferred for superior surface finish in finishing operations.
