Built to DIN 338 and ANSI standards, this heavy-duty bit features a 135-degree split point for reduced walking and faster penetration on hard stock. The 6.70 mm (0.2638 inch) diameter, right-hand spiral flute geometry and straw oxide finish help extend tool life during repetitive drilling operations. Licensed trades and machining professionals reach for this bit when productivity and hole quality matter on ferrous and mixed-material work.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for production drilling, maintenance, and fabrication environments where steel, cast iron, non-ferrous metals, and composite materials are encountered. The straight cylindrical shank fits standard three-jaw drill chucks on floor-standing drill presses, magnetic base drills, and hand-held power drills. The 9xD flute-to-diameter ratio and web-thinned, tapered web configuration support chip evacuation in deeper holes without regrinding.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction for heat and wear resistance in hard metal drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree web-thinned point reduces thrust force and minimizes bit walking on entry\u003c\/li\u003e\n  \u003cli\u003eStraw oxide finish provides lubricity and basic corrosion protection\u003c\/li\u003e\n  \u003cli\u003eRegular right-hand spiral flute promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 and ANSI dimensional standards for interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard three-jaw drill chucks accepting straight-shank bits with a 6.70 mm (0.2638 inch) shank diameter.

Always power down and lock out the drilling machine before changing bits. Seat the straight shank fully into the chuck and tighten securely to prevent slippage under load. Do not exceed the rated drilling depth of 2.48 inches without retracting to clear chips, and use appropriate cutting fluid for ferrous workpieces to maximize tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.70 mm (0.2638 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.9688 inches (3-31\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.4844 inches (2-31\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.4803 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.70 mm (0.2638 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4961 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral, Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 9xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P, M, K, N, S classifications)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2ACO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 338, ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 pounds\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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6000643\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51714915696946,"sku":"6000643","price":19.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/758de141a9fc20af5d344d75acdd3f69_9aef9953-6f44-4a47-af7e-73d54297b5a3.jpg?v=1788507842","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000643-cobalt-jobber-drill-6-70mm","provider":"Voomi Supply","version":"1.0","type":"link"}
