The bit measures 2.50 mm (0.0984 inches) in diameter with an overall length of 57.00 mm (2.25 inches) and a flute length of 30.00 mm (1.1875 inches). The 135-degree split point reduces walking on entry and lowers thrust requirements compared to a standard 118-degree point. An oxide and straw finish provides mild lubricity and corrosion resistance during operation. This is a heavy-duty, general-purpose bit suited for use by machinists, maintenance technicians, and trade professionals drilling metal substrates.\u003c\/p\u003e\u003cp\u003eThis bit is well suited for drilling steel, cast iron, aluminum, non-ferrous alloys, and specialty alloys in both shop and field environments. The 12xD flute-to-diameter ratio is consistent with standard jobber-length geometry, making it appropriate for a wide range of benchtop drill presses, hand drills, and CNC drilling operations. The regular spiral flute type provides efficient chip evacuation in through-hole and blind-hole applications. It conforms to DIN 338 and ANSI standards, making it a direct fit for tooling setups that require dimensionally standardized drill stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction for improved heat and wear resistance when drilling hard steels\u003c\/li\u003e\n\u003cli\u003e135-degree web-thinned split point reduces entry walking and lowers required thrust\u003c\/li\u003e\n\u003cli\u003eOxide and straw finish adds lubricity and mild corrosion resistance\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with tapered web configuration promotes reliable chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 338 and ANSI dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill bit compatible with standard three-jaw drill chucks accepting straight shanks at 2.50 mm (0.0984 inches) shank diameter. Suitable for use in hand drills, drill presses, and CNC equipment configured for straight-shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove the bit only with the drilling equipment powered off and fully stopped. Secure the straight shank in a properly sized drill chuck and tighten with a chuck key before operation. Appropriate cutting fluid or coolant is recommended when drilling ferrous metals to extend bit life, even though this bit does not support through-tool coolant delivery. Follow applicable shop safety practices and equipment manufacturer guidelines when selecting feed rate and spindle speed for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.50 mm (0.0984 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\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 Split Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide and Straw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 57.00 mm (2.25 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 30.00 mm (1.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 2.50 mm (0.0984 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 27.00 mm (1.063 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.1811 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, plus P, M, K, N, S material codes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\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\u003eWeight\u003c\/strong\u003e: 0.042 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 6000639\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51694260912434,"sku":"6000639","price":56.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/758de141a9fc20af5d344d75acdd3f69_fc6603f0-2249-4c41-beb5-ece47a64e151.jpg?v=1788322330","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000639-cobalt-jobber-drill-2-50mm","provider":"Voomi Supply","version":"1.0","type":"link"}
