Built to DIN 338 and ANSI standards, it features a 135-degree split point with web thinning for reduced walking and easier entry without a center punch. The 8.20 mm (0.3228 inches) diameter, two-flute regular spiral geometry moves chips efficiently during through-hole and blind-hole operations. An oxide and straw-finish coating provides added lubricity and heat resistance. This bit is suited for machinists, maintenance technicians, fabricators, and tool-room professionals who need reliable performance in ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThe 6000559 is built for drilling steel, stainless, cast iron, aluminum, and non-ferrous alloys, corresponding to material codes P, M, K, N, and S. The straight cylindrical shank fits standard drill chucks on floor-standing drill presses, benchtop machines, and hand-held power drills. With a flute-by-diameter ratio of 9xD, this bit handles deeper drilling passes without sacrificing chip evacuation. It is a practical choice for production shops, maintenance facilities, and job-site metalwork where a consistent, heavy-duty cobalt bit is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high-speed steel construction for heat resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning reduces thrust and minimizes drill walking\u003c\/li\u003e\n\u003cli\u003eOxide and straw finish coating improves lubricity and extends tool life\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry with 9xD ratio supports deeper drilling and efficient chip removal\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n\u003cli\u003eMeets DIN 338 and ANSI standards for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose cobalt jobber drill for use in standard drill chucks across drill presses and handheld power drills; suitable for drilling steel, stainless steel, cast iron, aluminum, and other non-ferrous alloys (material codes P, M, K, N, S).\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or maintenance technician familiar with rotating cutting tools. Secure the workpiece firmly before drilling and ensure the chuck is fully tightened on the straight shank before operation. Power down and disconnect the machine before changing bits. Do not exceed the recommended feed and speed parameters for the workpiece material and bit diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.20 mm (0.3228 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 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: Oxide and Straw (Bronze)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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: 75.00 mm (2.9531 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 117.00 mm (4.6094 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.2 mm (0.3228 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 42 mm (1.6535 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\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\u003ePoint Type\u003c\/strong\u003e: Standard Split Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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 Non-Ferrous Metals (P, M, K, N, S)\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\u003eDouble Margin\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\u003eWeight\u003c\/strong\u003e: 0.083 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: 6000559\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51691709137202,"sku":"6000559","price":25.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/758de141a9fc20af5d344d75acdd3f69_4ffd3afb-591c-4866-9ea7-43b05beac48e.jpg?v=1788288769","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000559-cobalt-jobber-drill-8-20mm","provider":"Voomi Supply","version":"1.0","type":"link"}
