TDMN110308 NS740 — Triangular indexable milling insert, 60° geometry, 0.8 mm corner radius (Tungaloy)

The TDMN110308 NS740 is a triangular indexable insert designed for milling, optimised for finishing and light cuts in steel within compatible Tungaloy milling systems

• Triangular 60° geometry for versatile milling
• NS740 cermet grade for superior surface finish
• 0.8 mm corner radius for accurate edge definition
• Compatible with Tungaloy milling systems

Optimised finishing performance for consistent surface quality

The insert is engineered as a cermet finishing grade to deliver improved surface finish and tight dimensional control in finishing and light machining of steel. The NS740 composition emphasises stable edge behaviour and uniform wear, which reduces variability part-to-part and helps maintain tolerances over longer tool life. As an indexable insert, it offers repeatable edge seating and measurable performance, supporting predictable cycle times and fewer interruptions for rework.

Secure seating and straightforward system integration

A core advantage is the standardised triangular 60° geometry combined with a defined seat requirement: plate seat, geometry and milling body must match technically for secure clamping and optimal heat transfer. The insert’s 60° shape and a thickness of 3.18 mm ensure mechanical stability in appropriate cutter bodies. The absence of a centre hole and a plain seat design focus the clamping load on the periphery, delivering stable cutting conditions when mounted in compatible Tungaloy systems.

Predictable edge life and productivity in finishing cuts

The 0.8 mm corner radius supports accurate edge definition and smoother transitions during shoulder and face milling, reducing vibration and improving surface integrity. For finishing passes, the NS740 grade balances sharpness and wear resistance: sharper edges for quality surfaces, yet robust enough to resist premature breakdown. This combination translates into efficient machining cycles, fewer insert changes and a measurable impact on overall process stability and output.

FAQ

Is this insert suitable for finishing steel? The TDMN110308 NS740 triangular indexable insert is specified for finishing to light machining of steel, offering high surface quality and consistent wear for dimensional accuracy.

Which tool bodies are compatible with this insert? Compatibility requires matching the insert seat, geometry and milling body; the insert is intended for use with Tungaloy milling systems that accept TDMN-format triangular inserts.

What benefits does the NS740 cermet grade provide? NS740 delivers a balance of sharpness and wear resistance, improving surface finish and promoting even wear, which supports repeatable finishing results.

Can the insert be used for heavy roughing or high-feed milling? This grade is optimised for finishing and light cuts; for heavy roughing or high-feed applications, select a grade and geometry designed specifically for higher metal removal rates.

What are the key edge and dimensional specs to consider? Key specifications include a 60° included angle, 0.8 mm corner radius and 3.18 mm plate thickness; confirm these match the cutter body and required machining strategy.
