It delivers a 118-degree standard point angle and a right-hand spiral flute configuration suited for general-purpose drilling in production and maintenance environments. The overall length is 3.5 inches with a 2-5\/16-inch flute length, providing the reach and chip-clearing capacity typical of jobber-series bits. This bit is sized and finished to ANSI and NAS 907 standards and is installed by machinists, pipefitters, HVAC fabricators, and general trade technicians working with ferrous and non-ferrous base metals.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It suits both hand-held drill applications and drill press setups in light industrial and field service contexts. The straight cylindrical shank fits standard three-jaw chucks, and the 12xD flute-to-diameter ratio supports adequate chip evacuation at moderate feed rates. The steam oxide finish provides a degree of lubricity and surface hardness that extends tool life in ferrous drilling operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge No. 11 sizing at 0.1910 inches decimal equivalent\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web geometry\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating for improved lubricity and wear resistance on ferrous materials\u003c\/li\u003e\n\u003cli\u003eTwo-flute right-hand spiral for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and NAS 907 specification standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with any standard three-jaw drill chuck accepting a 0.1910-inch straight cylindrical shank, for use across Series R10A, R15A, and R18A application contexts.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by machinists, sheet metal workers, pipefitters, and field service technicians using a hand drill or drill press. Power down all equipment and secure the workpiece before bit changes. Use appropriate cutting fluid or lubricant when drilling stainless steel, cast iron, or superalloys to extend tool life and prevent work hardening. Do not exceed the manufacturer-recommended feed rate for the base material being drilled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\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\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\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\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Drilling, General Purpose\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\u003eSeries\u003c\/strong\u003e: R10A, R15A, R18A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NAS 907\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 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: 5999278\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51698522325298,"sku":"5999278","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb0d3aa62b12a911c87b71fb6c8893a6_8cc1b6ad-504c-4bfc-98c6-e4329dd22313.jpg?v=1788364178","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999278-jobber-drill-bit-no-11","provider":"Voomi Supply","version":"1.0","type":"link"}
