Built to DIN 340 standards, it carries a 0.2570-inch (Letter F) diameter with a 130-degree split point angle and a parabolic flute geometry that promotes efficient chip evacuation. The high-speed steel construction is coated for improved wear resistance and tool life. Overall length is 5-13\/16 inches, with a flute length of 3-13\/16 inches and a 10xD flute-to-diameter ratio. The cylindrical shank measures 6.53 mm in diameter. This is a right-hand cut bit intended for use by machinists, tool-room technicians, and maintenance professionals running manual or CNC drilling operations.\u003c\/p\u003e\n\u003cp\u003eThe 9006680065300 is suited for through-hole and deep-hole drilling in aluminum alloy, brass, and steel. Its web-thinned, parallel web configuration reduces thrust requirements and improves centering at entry. The maximum drilling depth is 3.4330 inches (87.21 mm), making it appropriate for applications requiring extended reach beyond what a jobber-length bit provides. Series 668 is GUHRING's high-performance HSS taper length line, conforming to DIN 340 geometry specifications. Typical use cases include production drilling, maintenance repair, and prototype work where a standard-length bit cannot reach the required depth.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDIN 340 taper length geometry with 5-13\/16 inch overall length for extended reach\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design promotes rapid chip evacuation in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web reduces entry thrust and improves point stability\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003e130-degree standard point angle compatible with common drill press and CNC setups\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in aluminum alloy, brass, and steel.
