SDMR 1203AE NS740 Milling Indexable Insert — Tungaloy

The SDMR 1203AE NS740 is a square indexable insert for finishing and light milling of steel within Tungaloy milling systems.

• Square 12 mm insert for stable positioning
• Cermet grade NS740 for superior surface finish
• 15° clearance angle for reduced rubbing
• Single-sided chipbreaker for controlled chip flow

Delivering consistent surface quality with cermet precision

Aimed at finishing operations, this insert leverages the NS740 cermet grade to provide excellent surface finish and dimensional accuracy during light milling of steel. Cermet combines ceramic hardness and metal toughness to reduce built-up edge and promote uniform wear, which in turn lowers rework rates and improves process repeatability. The result is a predictable cutting performance that supports tighter tolerances and less downstream machining.

Secure seating and geometry for repeatable results

Designed for use in matched Tungaloy milling bodies, the insert requires correct plate seat, geometry and clamping hardware to perform as intended. The square 12 mm form with an included angle of 90° and 15° clearance minimises flank contact and ensures clean entry into the workpiece. With a thickness of 3.18 mm and a corner radius of 0, the insert provides a precise engagement geometry; the absence of a hole necessitates compatible clamping solutions on the toolholder for secure fixation and consistent cutting forces.

Application range and machining advantages

Suitable for face, shoulder, slot, high-feed and contour milling depending on the tool family, the insert is optimised for finishing to light removal rates on steel where surface quality and measure stability are priorities. The single-sided chipbreaker directs chips reliably, supporting process stability and easier chip evacuation in production environments. Shops focused on precision components and high-quality surfaces will benefit from reduced polishing or secondary finishing and more consistent part-to-part results.

FAQ

What materials is this insert suitable for? The SDMR 1203AE NS740 insert is specified for finishing and light machining of steel, with the NS740 cermet grade prioritising surface quality and dimensional stability.

How is the insert clamped in the milling body? The square insert requires a matching plate seat and clamping screw in the Tungaloy milling body; the SDMR1203AE is supplied without a hole and must be used with a compatible clamp arrangement.

What does the 15° clearance angle mean in practice? A 15° clearance reduces flank rubbing during engagement, improving surface finish and lowering heat at the cutting edge for more even wear on the NS740 cermet grade.

Is this insert suitable for high-feed milling? Application depends on the assigned tool family; while the SDMR 1203AE can be used in various milling types, it is optimised for finishing to light machining rather than heavy high-feed removal.

How can the SKU help when ordering replacement inserts? Referencing the SKU 6821496-Tungaloy or article number 6821496 ensures the correct SDMR 1203AE NS740 insert and avoids mismatches with geometry or grade.
