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.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Flute Geometry:\u003c\/strong\u003e improves slotting, reduces total cutting force and clears debris easily.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Chip Former:\u003c\/strong\u003e better chip removal and control, supporting continuous machining.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolished Flutes:\u003c\/strong\u003e increased chip passage and less friction at contact points, so less heat and a better finished surface.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Construction:\u003c\/strong\u003e built for rigidity and wear resistance across one-off jobs and large runs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible Applications:\u003c\/strong\u003e optimized for ISO N materials, from initial slotting through contour finishing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy Three Flutes\u003c\/h3\u003e\n\u003cp\u003eThree 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.\u003c\/p\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003eSlotting, 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.\u003c\/p\u003e\n\u003ch3\u003eAMC7091 Series Variants\u003c\/h3\u003e\n\u003cp\u003eAvailable across a range of cutting edge diameters, cutting edge lengths and shank diameters — see the variant list for exact sizing.
