XCET310404ER 310404 NS740 milling insert – DoFeed high‑feed series by Tungaloy

A XCET310404ER NS740 insert engineered for high‑feed milling, optimised for pocketing and face machining with small axial depths and large chip volumes

• DoFeed high‑feed design for large chip volumes
• NS740 cermet grade for superior surface finish
• 0.4 mm corner radius for precise finishing

Maximise removal rates with shallow axial cuts

The DoFeed family is designed to deliver high material removal rates at small axial depths, converting multiple light passes into efficient, high‑feed operations. By using a shallow immersion depth combined with a robust cutting geometry, the system achieves consistent chip volume per engagement and reduces cycle time without excessive radial load. This approach is particularly suitable for pocketing and face milling where stability and repeatable material extraction are critical. The result is a measurable gain in productivity while maintaining process control.

Achieve fine surface quality and dimensional stability with NS740

The NS740 grade, a cermet or coated cermet option, focuses on finishing and light machining of steel with emphasised surface quality and dimensional accuracy. The fine microstructure of the grade yields even wear and a stable cutting edge, which helps preserve tolerances over longer tool life. For users seeking improved part appearance and repeatability, this grade reduces the need for downstream finishing and supports reliable batch production. Selection of this grade therefore benefits both quality assurance and overall economics.

Reliable seating, secure clamping and application details

The insert is supplied in a special plate form with a plate size of 31 mm and a plate thickness of 4.76 mm, providing a stable seating surface for high‑feed applications. The 0.4 mm corner radius supports precise finishing passes, while the 7° relief angle aids chip evacuation and reduces rubbing. The insert features a cylindrical hole with a single‑side countersink (40°–60°) for secure clamping and accurate repeatability in the milling body. A one‑side chipbreaker promotes controlled chip formation under the DoFeed cutting conditions. The system comprises the milling body, matching replaceable inserts and clamping screws to ensure straightforward assembly and repeatable set‑ups.
