It measures 3\/8 inch in diameter with a 0.437-inch length of cut, a 2-inch overall length, and a 3\/8-inch square shank held to h6 tolerance. The variable helix geometry and chipbreaker features work together to reduce harmonics, improve chip evacuation, and extend tool life. The nACRo coating adds thermal and wear resistance, making this end mill well suited for demanding cutting applications across ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for professional machinists and tooling specialists working in CNC milling environments. It is applicable to workpiece material codes H, K, M, N, P, and S, covering a broad spectrum including steels, cast irons, stainless steels, non-ferrous metals, long-chipping materials, and heat-resistant superalloys. The single-end, right-hand cutting and right-hand flute configuration makes it a standard fit for conventional CNC machining center setups. The upcut flute type promotes chip clearing away from the workpiece surface.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-flute geometry increases feed rates and improves surface finish compared to lower-flute-count alternatives\u003c\/li\u003e\n  \u003cli\u003eVariable helix design reduces chatter and vibration during cutting\u003c\/li\u003e\n  \u003cli\u003eChipbreaker feature aids chip control and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003enACRo coating provides elevated thermal resistance and extended wear life\u003c\/li\u003e\n  \u003cli\u003eSubmicron carbide grade delivers fine grain structure for edge toughness and hardness\u003c\/li\u003e\n  \u003cli\u003eh6 shank tolerance ensures consistent, accurate tool holding in standard collets and chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for workpiece material codes H, K, M, N, P, and S.
