The bit is manufactured from high speed steel and carries a steam oxide coating that reduces friction and extends cutting life in ferrous materials. It features a 118-degree standard point angle, a regular spiral flute with web-thinning, and a right-hand cutting direction. Overall length is 3.5 inches with a 2.3125-inch flute length. Licensed tradespeople and machinists use this bit for general-purpose drilling in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium in both shop and field applications. The straight-cylindrical shank seats directly in standard drill chucks without adapters, making it compatible with handheld drills, drill presses, and CNC drilling setups. The Series R18 designation places it within a general-purpose jobber line intended for everyday production drilling where a consistent, reliable hole in a range of materials is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge No. 11 sizing at 0.1910 inches decimal for precise hole specification matching\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles heat generated in ferrous and hard material drilling\u003c\/li\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 for general-purpose entry into a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces thrust load and improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with 12xD flute-to-diameter ratio supports maximum drilling depth of 2.3125 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with standard straight-shank drill chucks across handheld, bench, and machine tool applications.

Secure the workpiece firmly before engaging the bit to prevent walking at the point. Power down and de-energize any machine tool before changing bits or adjusting chuck tension. Do not exceed the maximum drilling depth of 2.3125 inches in a single pass without withdrawing the bit to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1910 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\u003eDrill Bit Material\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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\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: 2.3125 inches (2-5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.3125 inches (2-5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches (3-1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1910 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1875 inches (1-3\/16 inches)\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 12xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\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: R10-R15-R18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 5998288\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51707035091250,"sku":"5998288","price":56.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2bbd17554f8298fe95bb319a732ccea_d3e49b20-7fb3-4224-96ad-3189f591319d.jpg?v=1788437974","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998288-jobber-drill-bit-no-11","provider":"Voomi Supply","version":"1.0","type":"link"}
