Ground from high speed steel (HSS) and finished with a steam oxide coating, it provides moderate lubricity and corrosion resistance during drilling operations. The 135-degree split point reduces walking on entry and lowers thrust requirements compared to a conventional 118-degree point. The web-thinned, tapered web construction improves chip evacuation and reduces heat buildup at the cutting edge. Flute length is 2.3125 inches and overall length is 3.5 inches. This bit is sold individually and is sized at 0.1850 inches decimal diameter.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It fits standard drill chucks via its straight cylindrical shank and is applicable in hand-held drills, drill presses, and CNC drilling operations requiring a wire-gauge No. 13 hole. The Series R18B designation places it in the heavy-duty jobber category conforming to ANSI and NAS 907 standards. Typical users include machinists, maintenance technicians, and metalworking fabricators performing repetitive through-hole and clearance-hole drilling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge No. 13 (0.1850 inches) straight cylindrical shank matches decimal drill chuck collets without adapter\u003c\/li\u003e\n  \u003cli\u003e135-degree standard split point reduces drill walk and lowers entry thrust on hard materials\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating improves surface lubricity and provides mild rust resistance during storage and use\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web promotes chip clearance and reduces heat in deep-hole applications up to 2.3125 inches depth\u003c\/li\u003e\n  \u003cli\u003eTwo-flute spiral construction with regular spiral type balances chip removal against rigidity\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and NAS 907 specification for consistent dimensional tolerance across production runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard drill chucks accepting a 0.1850-inch straight cylindrical shank.

Use appropriate cutting fluid or coolant for stainless steel, superalloys, and titanium to extend tool life; this bit does not support coolant-through delivery. Inspect the cutting edges before each use and replace if chipping or wear is visible to maintain hole quality. Follow applicable shop safety standards for rotating tool use, including eye protection and secure workholding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1850 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1850 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1875 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High speed steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam oxide\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: 2.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10B-R15B-R18B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NAS 907\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: 0.18 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: 5999062\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51722206445874,"sku":"5999062","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7da465a3340ea6a9db91bc6a63822e95_754538ea-b07e-4cb1-8826-0ad1907e177e.jpg?v=1788587390","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999062-jobber-drill-bit-no-13-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
