Built to DIN 338 and ANSI standards, this bit features a 135-degree split point with web thinning that reduces walking on entry and lowers thrust requirements at the spindle. The straw oxide finish provides light surface protection and helps with chip identification during cutting. At 4.6094 inches overall length with a 2.9531-inch flute, it fits standard jobber drill applications on drill presses, lathes, and hand-held power tools used in metalworking and fabrication trades.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling steel, cast iron, aluminum, non-ferrous metals, and high-temperature alloys, consistent with its P, M, K, N, and S workpiece material classifications. The straight cylindrical shank fits standard three-jaw chucks without adapters. Its 9xD flute-to-diameter ratio and regular spiral flute geometry make it a reliable choice for production and maintenance drilling in shop and field settings where a heavy-duty cobalt bit is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for increased heat resistance and durability in hard metal drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces walking and lowers required feed force\u003c\/li\u003e\n  \u003cli\u003eStraw oxide finish for light surface protection and chip color reference\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute geometry promotes efficient chip evacuation in through-hole drilling\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard three-jaw drill chucks without modification\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 and ANSI standards for consistent dimensional and performance tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber drill for use in drill presses, milling machines, lathes, and hand-held power tools equipped with a standard three-jaw chuck sized for an 8.00 mm or 0.3150-inch straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by machinists, tool-and-die technicians, or qualified metalworking tradespeople familiar with proper speeds and feeds for cobalt tooling. Secure the straight shank fully in the chuck and verify runout before engaging the workpiece. Wear appropriate eye protection and ensure the workpiece is firmly fixtured before drilling. Do not exceed the drill's rated flute depth of 2.9531 inches when boring through material in a single pass without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.00 mm (0.3150 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard split point, 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\u003eFlute Type\u003c\/strong\u003e: Regular spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.9531 inches (75.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.6094 inches (117.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3150 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.6535 inches (42.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.9531 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 9xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, and compatible with P, M, K, N, S material classifications\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General purpose, heavy duty grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2ACO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 338, ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08333 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: 6000556\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51689157361970,"sku":"6000556","price":23.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/758de141a9fc20af5d344d75acdd3f69.jpg?v=1788255310","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000556-cobalt-jobber-drill-8mm","provider":"Voomi Supply","version":"1.0","type":"link"}
