Manufactured from solid carbide with an AlTiN coating, it delivers excellent heat resistance and extended tool life in ferrous and hard-to-machine materials. The 5\/16 inch diameter tool features 4 flutes in a right-hand spiral configuration with a fine pitch profile that reduces chatter and vibration during heavy cuts. At 2-1\/2 inches overall length with a 13\/16 inch length of cut, this end mill suits a range of short-reach roughing applications. A Weldon flat shank provides positive drive and minimizes pullout under high-feed conditions. This tool is installed by machinist-level trades and CNC tooling professionals.\u003c\/p\u003e\n\u003cp\u003eThe SECO 17004665 is suited for roughing passes in vertical machining centers, CNC mills, and manual knee mills where a 5\/16 inch tool diameter is appropriate. The AlTiN coating and solid carbide substrate make it a strong candidate for dry or minimal-coolant cutting in hardened steels and stainless alloys. The center-cutting geometry allows plunge entry, giving the operator flexibility to enter a workpiece directly without pre-drilling. The 20-degree maximum helix angle and fine pitch design are optimized for controlled chip evacuation in tight-tolerance pocketing and slotting operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard-material applications\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides high-temperature oxidation resistance, extending tool life in dry cutting\u003c\/li\u003e\n  \u003cli\u003e4-flute fine pitch design reduces vibration and chatter during roughing passes\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry enables direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank minimizes tool pullout under aggressive feed conditions\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute spiral for standard CNC and manual mill spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for milling applications requiring a 5\/16 inch diameter, 4-flute solid carbide roughing end mill with a Weldon flat shank.
