TPMN 110304 NS740 – Indexable milling insert for finishing (Tungaloy)

The TPMN110304 NS740 is an indexable triangular insert for milling, optimised for finishing and light machining of steel in compatible Tungaloy milling systems.

• NS740 cermet for superior surface finish
• Triangular form, 11 mm size, 60° cutting angle
• 0.4 mm corner radius for precise profiling
• Designed for finishing and light machining of steel

Achieve consistent surface quality with a finishing cermet

The NS740 grade is a cermet developed for the final machining steps where surface quality and dimensional accuracy are critical. As a finishing insert, it supports stable, uniform wear and reduces the need for rework by delivering predictable results on steel components. The material composition of this grade promotes a fine cutting action that improves finish without sacrificing tool life, making it suitable where aesthetic and tolerance demands matter.

Geometry engineered for repeatable accuracy

A triangular plate form with an effective cutting angle of 60° and an insert size of 11 mm provides a reliable geometry for shoulder, face and contour milling operations. The 0.4 mm corner radius supports precise profiling while avoiding excessive tool load in finishing passes. With a plate thickness of 3.18 mm and a relief angle of 11°, the insert ensures mechanical stability in the cutter pocket when correctly mounted; note that seat, geometry and cutter body must be compatible within the Tungaloy range for optimal clamping and repeatability.

Productivity benefits for milling operations

Using a grade optimised for finishing and light machining improves throughput by maintaining consistent wear and stable chip formation over longer sequences. The insert’s design focuses on predictable behaviour during planing, shoulder, slot, high-feed and contour milling (depending on the assigned tool family), which supports tighter process control and less scrap. For production environments prioritising part quality and repeatability, this insert helps reduce cycle time variances and contributes to overall process security.

Simple integration into indexable tool systems

The insert is supplied for use in a system comprising cutter body, indexable insert, clamping screw and, where applicable, shim or backing. Its triangular form and lack of a centre hole mean compatibility must be checked against the cutter pocket design; correct seating and the clamping screw are essential for reliable performance. Technical advice is available to ensure selection of the appropriate cutter body and clamping hardware so that the insert’s potential for finishing and dimension control is fully realised.

FAQ

What machining tasks suit this insert best?
This insert is intended for finishing and light machining of steel; the NS740 grade provides improved surface quality for face, shoulder and contour milling in compatible Tungaloy tool families.

Is the insert compatible with all Tungaloy cutter bodies?
Compatibility requires matching of the insert seat, plate geometry and cutter body; confirm that the cutter pocket accepts a triangular TPMN110304 style insert before assembly.

What does NS740 mean in practice?
NS740 denotes a cermet grade tuned for finishing: it balances wear resistance and cutting-edge quality to deliver consistent surface finish and dimensional accuracy on steel.

How many active edges are available per insert?
The triangular form provides multiple indexable edges; precise edge count depends on the specific insert orientation and indexing practice used in the tool holder.

Are there chipbreakers or centre holes on this insert?
This item is supplied without a chipbreaker and without a centre hole; clamping and seat design must account for this specification.
