It carries a Titanium Nitride (TiN) coating over a cobalt steel substrate, extending tool life compared to standard high-speed steel bits. The drill is ground to a 130-degree point angle with a web-thinned, tapered web configuration for reduced thrust and cleaner entry. A parabolic flute geometry promotes efficient chip evacuation during deep-hole drilling. Overall length is 101 millimeters, with a straight-cylindrical shank measuring 0.2598 inches in diameter. The flute length runs 2-15\/32 inches. Licensed machinists, tool-and-die workers, and maintenance technicians are the primary users of this drill.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production and maintenance drilling in ferrous metals, stainless steel, cast iron, and other hard materials where cobalt-grade tooling is specified. It follows the DIN 338 standard, which governs jobber-length twist drills common across European and North American manufacturing and fabrication shops. Right-hand cutting geometry is standard for conventional drill press, CNC, or hand-drill applications. The 6.6 mm diameter falls within the 6.00 to 7.00 mm size range and converts to 0.2598 decimal inches, making it a close fit to a 17\/64-inch nominal dimension. This bit ships individually but is subject to a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt steel construction with Titanium Nitride (TiN) coating for extended heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle reduces walking and improves chip formation on hard materials\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes fast chip evacuation and reduces heat buildup in deep holes\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web lowers drilling thrust and extends machine spindle life\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 338 specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 338 jobber-length twist drill for use in conventional drill presses, CNC machining centers, and portable hand drills equipped with standard straight-shank chucks accepting up to 0.2598-inch shank diameters. Suitable for ferrous and non-ferrous metal drilling where cobalt-grade tooling is specified. No coolant-through capability; external coolant or cutting fluid recommended for prolonged use in hard materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the straight-cylindrical shank firmly in a properly sized drill chuck before use; a loose chuck grip can cause runout and premature coating wear. Always power down and lock out the machine spindle before inserting or removing the drill bit. Apply appropriate cutting fluid or coolant externally when drilling ferrous metals to manage heat and extend tool life. Do not exceed the drill press or machine manufacturer's recommended feed rate and spindle speed for the workpiece material and this diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.6 mm (0.2598 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 101 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-15\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2598 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.022 to 0.000 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9006580066000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51753314320690,"sku":"9006580066000","price":637.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f10a9cb056c7cb50defcf0917176d81.jpg?v=1788935312","url":"https:\/\/voomisupply.com\/products\/guhring-9006580066000-cobalt-drill-bit-6-6-mm-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
