Built from high speed steel (HSS) with a gold oxide coating, it provides improved lubricity and surface hardness compared to uncoated HSS. The bit measures 21\/64 inch (0.3281 inch decimal) in diameter with an overall length of 4-5\/8 inches and a flute length of 3-5\/16 inches. The 118-degree split point reduces walking on entry and lowers thrust requirements, making it practical for hand-held drilling and drill press work alike. Plumbers, pipefitters, electricians, and HVAC technicians reach for jobber-length bits as a standard go-to for clearance holes, pilot holes, and general metal fabrication tasks.\u003c\/p\u003e\u003cp\u003eThis bit fits standard drilling operations across residential and light commercial job sites. It is suited for ferrous metals, mild steel, and similar materials encountered in mechanical, plumbing, and electrical rough-in work. The straight cylindrical shank is compatible with standard three-jaw chucks on corded and cordless drills and drill presses. The right-hand spiral flute clears chips efficiently during through-hole drilling. Series 314 identifies this as a general-purpose jobber-length configuration intended for repeated production or service use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e21\/64 inch diameter with 0.3281 inch decimal equivalent for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e118-degree split point reduces bit walking and lowers required feed pressure\u003c\/li\u003e\n\u003cli\u003eGold oxide finish improves lubricity and extends service life versus bare HSS\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with tapered web configuration promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard three-jaw drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eWeb-thinned construction reduces heat buildup during repeated drilling cycles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in any standard three-jaw chuck accepting a 21\/64 inch straight shank, including corded drills, cordless drills, and bench-mounted drill presses.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the shank fully in the chuck and tighten all jaws evenly before drilling. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat. Ensure the workpiece is clamped or secured before applying feed pressure to prevent spinning. Follow applicable OSHA and shop-safety guidelines for rotating tool operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 21\/64 inch (0.3281 inch decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 21\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\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\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Gold Oxide\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: 314\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: IMPORT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 22442\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51689625092402,"sku":"22442","price":86.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f41674463c1835cd158620c303ff9fd.jpg?v=1788262067","url":"https:\/\/voomisupply.com\/products\/import-22442-jobber-length-drill-bit-21-64-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
