Onsrud 3 Flute Solid Carbide End Mill — Square, Standard Length, Necked
A three-flute solid carbide end mill built for non-ferrous work — aluminum, brass, bronze and copper. The polished channel design and open flute geometry keep chips moving instead of packing, which limits heat buildup and supports longer uninterrupted runs in both quick-turn prototyping and volume production.
Key Features
- Open Flute Geometry: improves slotting, reduces total cutting force and clears debris easily.
- Advanced Chip Former: better chip removal and control, supporting continuous machining.
- Polished Flutes: increased chip passage and less friction at contact points, so less heat and a better finished surface.
- Tool Construction: built for rigidity and wear resistance across one-off jobs and large runs.
- Flexible Applications: optimized for ISO N materials, from initial slotting through contour finishing.
Why Three Flutes
Three flutes balance chip clearance against edge stability — smoother finishes and better tool stability at speed than a two-flute, without the chip-packing risk of a four-flute in soft non-ferrous metal. The result is minimized burring and cleaner edges, with a constant feed and faster cycle times.
Applications
Slotting, pocketing, contouring and finishing on CNC equipment. The structure holds up at high spindle speeds, suiting aerospace, automotive and high-precision component work, including deep material removal where tight tolerances matter.
