It features a 135-degree split point with web thinning for fast penetration and reduced walking at entry. The 1.05 mm diameter and straight cylindrical shank suit standard drill chucks across benchtop drill presses, hand drills, and CNC drilling setups. With a straw oxide finish and tapered web configuration, this bit is built for general-purpose heavy-duty drilling in metalworking, fabrication, and maintenance environments. Machinists and tool-and-die technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling ferrous metals including steel, cast iron, and stainless, as well as aluminum and non-ferrous alloys. The Series 2ACO designation places it in a line built to DIN 338 and ANSI standards, making it a direct fit for applications requiring close-tolerance small-diameter drilling. The 11xD flute-to-diameter ratio provides adequate chip clearance even in deep-entry work relative to the bit size. Typical applications include precision hole placement in sheet metal, machined components, and tool fixtures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction for heat resistance in steel drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces thrust and self-centers on entry\u003c\/li\u003e\n  \u003cli\u003eStraw oxide finish provides lubricity and mild corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with tapered web for 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 standards for consistent dimensional tolerancing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or stock jobber drill bit for any drill chuck accepting a 1.05 mm straight shank.

Ensure the workpiece is secured before beginning any drilling operation. At this diameter, low feed pressure and appropriate RPM selection are critical to avoid bit breakage. No coolant-through capability is present on this bit, so external cutting fluid or oil is recommended when drilling hardened or stainless steel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.05 mm (0.0413 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\u003eMaterial\u003c\/strong\u003e: Cobalt High Speed Steel\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: 1-11\/32 inches (34.00 mm \/ 1.3438 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 15\/32 inches (12.00 mm \/ 0.4688 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.05 mm (0.0413 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 22 mm (0.8662 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.4724 inches\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2ACO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338, ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (Codes P, M, K, N, S)\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\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: 0.04167 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 5999614\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51715041362226,"sku":"5999614","price":67.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/758de141a9fc20af5d344d75acdd3f69_a068a2b8-9f9e-4db1-b523-2f643482aeb9.jpg?v=1788509183","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999614-jobber-drill-1-05mm-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
