Built from high speed steel with a bright uncoated finish, it features a standard 118-degree point angle and a two-flute right-hand spiral configuration. The straight-cylindrical shank measures 29\/64 inch in diameter, matching the bit diameter for consistent chuck engagement. Web-thinned construction reduces thrust force at the point and improves chip evacuation. This bit is a staple tool for machinists, maintenance techs, pipefitters, and general trade professionals working in metal fabrication and mechanical installation environments.\u003c\/p\u003e\u003cp\u003eThe 5998374 is suited for drilling into steel, cast iron, non-ferrous metals, superalloys, and titanium. With a flute-to-diameter ratio of 9xD and a maximum drilling depth of 4-3\/16 inches, it handles the typical hole depths required in structural and mechanical work. The regular spiral and tapered web configuration support consistent chip flow without coolant-through capability, making it appropriate for dry or externally lubricated drilling setups in shop and field conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned tip for reduced entry force\u003c\/li\u003e\n\u003cli\u003eRight-hand, two-flute spiral design promotes efficient chip removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for use with standard drill chucks\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general-purpose applications\u003c\/li\u003e\n\u003cli\u003eANSI-compliant construction in Series R10H-R18H\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with standard three-jaw drill chucks accepting a 29\/64-inch straight-cylindrical shank, suitable for bench drill presses, hand drills, and magnetic drills used across mechanical and trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is installed by trade professionals including machinists, pipefitters, and general maintenance technicians. Secure the straight-cylindrical shank firmly in the chuck before operation and verify chuck key removal prior to starting the drill. Apply appropriate cutting fluid when drilling ferrous metals to extend tool life and maintain hole quality. Inspect the point and flutes for wear or damage before each use and replace the bit if chipping or dulling is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 29\/64 inch (0.4531 inch decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 4-3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 29\/64 inch (0.4531 inch decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4375 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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10H-R18H\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: 0.083 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: 5998374\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51713649606962,"sku":"5998374","price":32.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac335c1d53632e99459aa82e5500dfd1_1347a01c-05dd-4a97-bd52-04b2450b6a09.jpg?v=1788494693","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998374-jobber-drill-bit-29-64","provider":"Voomi Supply","version":"1.0","type":"link"}
