It measures 8.50 mm (0.3346 inches) in diameter with an overall length of 4-39\/64 inches (117 mm). The 135-degree split point geometry reduces walking on entry and lowers thrust requirements, making it well-suited for hand-held drilling operations and drill press work where precise hole placement matters. The oxide and straw coating provides moderate lubricity and heat resistance during drilling cycles. A web-thinned, tapered web construction maintains cutting efficiency as the bit wears. Machinists, tool-and-die workers, pipefitters, and mechanical contractors rely on this series for general-purpose metal drilling tasks.\u003c\/p\u003e\u003cp\u003eThis jobber drill is built for drilling steel, cast iron, aluminum, non-ferrous metals, and select specialty alloys, consistent with the P, M, K, N, and S workpiece material codes. It conforms to DIN 338 and ANSI standards, making it a drop-in fit for standard drill chucks and CNC tool holders using straight-shank tooling. The 2ACO series is a general-purpose heavy-duty line sized for shops that drill a broad range of materials without switching to specialty carbide tooling. Typical applications include fabrication, maintenance and repair operations, and light production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high-speed steel construction for improved heat and wear resistance in steel and hard materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust and prevents bit walking on entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web maintains cutting efficiency and reduces feed force\u003c\/li\u003e\n\u003cli\u003eOxide and straw coating provides lubricity and mild corrosion resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flute with 2 flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 338 and ANSI standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with standard straight-shank drill chucks, keyed and keyless chucks, and collet systems accepting an 8.50 mm (0.3346 inch) shank diameter across drill presses, CNC machining centers, and hand-held power drills.\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 shank fully in the chuck and verify runout before drilling. Always wear appropriate eye protection and ensure the workpiece is clamped or fixtured before applying feed pressure. Follow applicable shop safety standards and the drill press or machine tool manufacturer guidelines for speed and feed selection based on workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.50 mm (0.3346 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High Speed Steel\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide and Straw\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-61\/64 inches (75 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-39\/64 inches (117 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3346 inches (8.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.6535 inches (42 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, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2-61\/64 inches (75 mm)\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 (P, M, K, N, S codes)\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: 0.083 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: 6000564\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693901644082,"sku":"6000564","price":26.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/758de141a9fc20af5d344d75acdd3f69_02249e25-22d6-49c0-8d3a-c700142c9d7f.jpg?v=1788318812","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000564-jobber-drill-8-50mm-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
