Built from high speed steel with an oxide coating, the bit measures 5\/16 inch in diameter with a 4.5-inch overall length and a 3.1875-inch flute length. The 118-degree standard point angle suits a wide range of common materials. A tapered web with web thinning reduces thrust and helps the bit start cleanly without walking. The tanged shank provides positive drive engagement in compatible chucks. This bit is sized for use by machinists, millwrights, HVAC technicians, plumbers, and electricians working with ferrous metals and general structural materials.\u003c\/p\u003e\n\u003cp\u003eThe 47504 is suited for production and maintenance drilling in residential and commercial settings. Typical applications include drilling pilot and clearance holes in steel plate, cast iron components, structural steel, and similar workpieces. The 2-flute spiral configuration with regular helix handles chip evacuation reliably in through-hole and blind-hole drilling. The 5\/16-inch shank diameter matches the bit diameter, fitting standard 3\/8-inch or 1\/2-inch keyed and keyless drill chucks commonly used in corded drills, drill presses, and magnetic base drills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction for durability in ferrous and general-purpose drilling\u003c\/li\u003e\n  \u003cli\u003eOxide finish improves lubricity and provides basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry into steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces cutting thrust and improves hole-start accuracy\u003c\/li\u003e\n  \u003cli\u003eRight-hand 2-flute spiral configuration promotes efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eTanged shank provides positive torque transfer in standard drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with standard 3\/8-inch and 1\/2-inch drill chucks.

Secure the workpiece before drilling to prevent rotation or movement during operation. Use appropriate cutting fluid when drilling steel or cast iron to extend bit life and improve hole quality. Inspect the bit for chipping or wear before each use and replace if the cutting edges are damaged.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3125 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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Tanged\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eFinish\/Coating\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 to 0.0000 inches\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: 250AN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 47504\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51748253794610,"sku":"47504","price":15.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b043ea53479c22381121e8fe4fcf230.jpg?v=1788891190","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-47504-5-16-inch-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
