SDGT 1204PD NS740 Tungaloy indexable insert for milling

The SDGT1204PD NS740 is an indexable insert for Tungaloy milling systems, intended for finishing to light machining of steel where surface quality and dimensional stability are decisive.

• NS740 cermet grade for superior surface finish
• Square 12 mm size with 4.76 mm thickness
• 15° clearance angle and 90° cutting edge
• Cylindrical hole with single-sided countersink

Reliable finish and repeatable dimensional control

The NS740 specification is a cermet grade optimised for finishing operations, offering a stable cutting edge that promotes a consistently fine surface finish and improved dimensional control on steel components. Cermet combines ceramic and metallic properties to reduce built-up edge and provide even wear, which means fewer interruptions for inspection and less time spent on rework. For assemblies where tolerance retention and appearance matter, this cutting material supports predictable results across batches.

Secure seating and geometry for consistent cutting performance

Designed as a square insert with a 12 mm side and 4.76 mm thickness, the insert features a cylindrical hole with a single-sided countersink (40°–60°) to ensure reliable clamping in compatible tool bodies. The 15° clearance behind the cutting edge and the 90° edge geometry provide stable engagement and clear definition of the machined shoulder or face. Correct matching of the insert seat, geometry and cutter body in a Tungaloy milling system prevents micro-movements and contributes directly to longer edge life and stable process behaviour.

Productivity advantages for finishing and light milling of steel

When used for face, shoulder, slot, high-feed or contour operations within the appropriate cutter family, the insert supports efficient cycle times by enabling longer intervals between indexings. The cermet composition focuses on reducing friction at the cutting zone, improving surface quality and lowering the frequency of secondary finishing. In production environments aiming to reduce inspection and touch-up costs, adopting a grade like NS740 can lead to measurable throughput benefits while maintaining part quality.

FAQ

What applications is this insert best suited for?
The SDGT1204PD NS740 insert is designed primarily for finishing and light milling of steel, including face, shoulder, slot, high-feed and contour operations when combined with the appropriate Tungaloy milling body.

How does the NS740 grade affect surface finish and tool life?
The NS740 cermet grade provides stable wear characteristics and reduced built-up edge, improving surface finish and offering predictable edge life in finishing applications.

Is the SDGT1204PD compatible with all Tungaloy cutters?
Compatibility requires matching the insert seat, geometry and cutter body; the SDGT1204PD must be used in Tungaloy milling systems that accept the SDGT1204PD form with the specified hole and clamping arrangement.
