SDGT1204AF NS740 – Indexable insert for finishing milling, Tungaloy

The SDGT1204AF NS740 indexable insert is designed for finishing and light steel milling within Tungaloy milling systems, offering consistent surface quality and repeatable seating.

• Cermet NS740 for fine finishing
• Square 12 mm insert, 4.76 mm thick
• 15° clearance angle for accurate cutting
• Cylindrical hole with single-sided countersink

Precise finishing and consistent component quality

Engineered for the final passes in steel machining, the insert’s NS740 cermet composition prioritises surface finish and dimensional stability. The fine-grain cermet substrate, combined with its application as a finishing to light machining grade, reduces flank wear and helps deliver consistent geometric tolerance. With a 12 mm edge length and a plate thickness of 4.76 mm, the design supports stable cutting conditions and repeatable part results while the 15° relief improves chip evacuation and contact conditions during low-depth finishing passes.

Secure clamping and system matching for reliable indexing

The square insert is supplied with a cylindrical hole and a single-sided countersink (40°–60°) to suit compatible Tungaloy milling bodies; seat geometry and clamping interfaces must match the cutter body for correct mounting. The insert’s squared form and zero corner radius promote predictable engagement at a 90° included angle, enhancing repeatability when indexing. Mechanical stability from the hole-and-screw arrangement ensures reduced micro-movement under load, which translates into fewer rework cycles and more consistent batch production when the insert is used in the specified tool family.

Versatile milling applications and production benefits

Suitable for face, shoulder, slot, high-feed and contour milling depending on the assigned tool family, this cermet grade emphasises uniform wear and good surface integrity in steel finishing operations. The single-sided chipbreaker supports controlled chip formation during low to moderate cutting depths, aiding process stability and tool life. The insert’s combination of geometry and material reduces the need for secondary finishing, contributing to higher throughput and a lower overall manufacturing cost per part when used in the correct setup; the SDGT1204AF can be selected where surface quality and dimensional accuracy are primary objectives.
