TDMN 110304 NS740 — Tungaloy triangular milling indexable insert, 0.4 mm radius

The TDMN 110304 NS740 is an indexable milling insert for finishing to light machining of steel in compatible Tungaloy milling systems

• Tungaloy NS740 cermet performance
• Triangle geometry for stable cutting
• 0.4 mm corner radius for precision
• 15° relief for controlled engagement

Achieve consistent surface quality with a finish-focused grade

The NS740 grade is a cermet formulation tuned for finishing and light machining of steel, prioritising surface finish and dimensional stability. In practice, this means the insert delivers a finely honed cutting edge and uniform wear over production runs, reducing variability between workpieces. The triangular shape and modest corner radius support predictable engagement conditions, so the toolpath produces repeatable results even in complex contouring tasks. Matching the insert seat, geometry and milling body within the Tungaloy system preserves the designed cutting conditions and helps maintain tight tolerances.

Reliable machining performance and material coverage

Engineered for plan, shoulder, slot, high-feed and contour milling depending on the associated tool family, the insert combines a wear-resistant grade with a stable cutting profile to extend usable life during finish passes. The cermet chemistry and coating strategy improve the stable cutting edge behaviour and promote consistent chip formation when machining steel. For production environments, that translates into fewer interruptions for insert changes, steady cycle times and predictable rework rates. Where high surface quality is a priority, this insert supports finish passes without compromising component accuracy.

Practical system benefits and mounting considerations

The triangular geometry provides three cutting corners per insert, supporting cost-efficient indexing and quick corner changes. With a 0.4 mm corner radius and a 15° relief angle, the insert balances edge strength and fine detailing for finish operations. The design is supplied without a hole, so clamping relies on the specified clamping screw and, where required, a backing plate; the order of components in the system is insert, clamping screw and, if applicable, underlay. Compatibility with Tungaloy milling bodies ensures secure seating and repeatable positioning, which is critical for achieving the advertised precision and surface quality in serial production.

FAQ

Is this insert compatible with non-Tungaloy milling bodies?
Compatibility requires identical insert seat and body geometry; the TDMN 110304 NS740 is designed for Tungaloy milling systems and may not seat correctly in other manufacturers’ bodies without matching interfaces.

What materials is the grade suitable for?
The NS740 grade is optimised for finishing to light machining of steel, offering improved surface quality and dimensional stability when used in appropriate finish passes.

What does the NS740 designation indicate?
NS740 denotes a cermet or coated cermet cutting grade focused on surface finish, uniform wear and dimensional control, intended for finishing operations on steel components.

Can the insert be used for high-feed milling?
High-feed use is possible when paired with a suitable high-feed tool family; suitability depends on the assigned cutter body and machining parameters, not solely on the insert shape.

How is the insert secured in the cutter body?
The insert is clamped using the standard clamping screw and, where required by the tool system, a backing pad; the insert is supplied without a hole, so the correct clamping components must be used.
