Ground from high-speed steel with a steam oxide coating, it measures 19\/64 inch (0.2969 inch) in diameter with a 4.375-inch overall length and a standard 118-degree point angle. The two-flute spiral design with a tapered web and web-thinned tip promotes efficient chip evacuation and reduces thrust on entry. This bit is suited for use in hand-held drills, drill presses, and CNC or manual machining setups where a straight-cylindrical shank is required. It is typically installed and operated by machinists, maintenance technicians, and trade professionals working in fabrication or service environments.\u003c\/p\u003e\n\u003cp\u003eThis Series R10 jobber drill bit is built for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. With a flute-to-diameter ratio of 10xD and a maximum drilling depth of 3.0625 inches, it handles a wide range of hole-making tasks in both light production and general maintenance applications. The straight-cylindrical shank seats securely in standard Jacobs-style chucks and collet holders commonly found across trade and shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSteam oxide coating reduces friction and provides light corrosion resistance during storage and use\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned tip lowers drilling thrust and improves self-centering on flat surfaces\u003c\/li\u003e\n  \u003cli\u003eTwo spiral flutes with regular helix promote consistent chip clearance in through-hole and blind-hole drilling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.2969 inch diameter fits standard drill chucks without an adapter\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration adds rigidity and reduces bit deflection at depth\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for jobber-length drill geometry and tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length replacement drill bit compatible with any drill press, hand drill, or machining center equipped with a standard chuck or collet accepting a straight-cylindrical shank in the 19\/64 inch diameter range.

Always power down and de-energize the drill press or disconnect the hand drill from its power source before changing bits. Use appropriate cutting fluid or coolant when drilling stainless steel, superalloys, or titanium to manage heat buildup, as this bit does not support through-coolant delivery. Follow applicable shop safety standards and wear appropriate eye protection during all drilling operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Inch)\u003c\/strong\u003e: 19\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal)\u003c\/strong\u003e: 0.2969 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2969 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\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: Spiral, Regular Helix\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\u003ePoint Type\u003c\/strong\u003e: Standard, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10\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\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 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: 5998704\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51722072260914,"sku":"5998704","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8285143b76113f15c5f987c3a55f96e2_b29ab208-f800-4b05-ae69-4f38ac7c0d64.jpg?v=1788585170","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998704-jobber-drill-bit-19-64","provider":"Voomi Supply","version":"1.0","type":"link"}
