It measures 7\/16 inch (0.4375 inch decimal) in diameter with an overall length of 5-1\/2 inches and a flute length of 4-1\/16 inches. The bit is manufactured from high speed steel with a gold oxide finish that provides mild lubricity and corrosion resistance during cutting operations. A 118-degree split point reduces walking on entry and requires no center punch on most surfaces. The straight-cylindrical shank at 3\/8 inch diameter fits standard three-jaw drill chucks. This bit is sold individually and is suited for use by machinists, pipefitters, electricians, and general trade technicians.\u003c\/p\u003e\u003cp\u003eThe IMPORT 22449 is appropriate for production and maintenance drilling tasks in residential and light commercial trade environments. Typical applications include drilling pilot holes for conduit fittings, pipe hangers, structural anchors, and sheet metal brackets. The regular spiral flute and tapered web with web thinning promote chip evacuation and reduce thrust in hand-held and drill-press setups alike. It is rated as a general-purpose grade bit suited to intermittent and moderate-duty use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/16 inch diameter with 0.4375 inch decimal equivalent for precise bit selection\u003c\/li\u003e\n\u003cli\u003e118-degree split point minimizes walking and reduces the need for center punching\u003c\/li\u003e\n\u003cli\u003eGold oxide coating provides mild lubricity and light corrosion resistance\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces cutting thrust and improves chip clearance\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 3\/8 inch shank fits standard drill chucks without adapters\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 3\/8 inch straight shank, including hand drills, drill presses, and magnetic base drills commonly used in trade work.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the shank fully in the drill chuck and tighten with a chuck key before drilling. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Ensure workpieces are clamped or secured before beginning any drilling operation. Inspect the cutting edges for wear or chipping before each use and replace bits that show signs of dulling to maintain cut quality and operator safety.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4-1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 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 Helix)\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\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: 22449\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51700086931762,"sku":"22449","price":115.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5100ac281bd5e6e9ca01a4494add37c4.jpg?v=1788385849","url":"https:\/\/voomisupply.com\/products\/import-22449-7-16-inch-hss-jobber-drill-bit-gold-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
