The bit is manufactured from high-speed steel (HSS) and finished in a black oxide straw coating that provides mild corrosion resistance and reduces friction during cutting. With a 49\/64-inch cutting diameter (0.7656 inches decimal equivalent), a 118-degree split point angle, and a 1\/2-inch reduced shank with three flats, this bit seats securely in standard chucks and prevents slippage under load. Overall length is 6 inches with a 3-inch flute length. Two flutes clear chips efficiently through the cut. This bit is installed by machinists, maintenance mechanics, and metalworking tradespeople.\u003c\/p\u003e\n\u003cp\u003eThe SD94749 belongs to TITAN USA Series 623 and is suited for general-purpose production and maintenance drilling applications. The reduced shank design allows a large-diameter bit to be used in a 1\/2-inch drill press chuck or handheld drill without requiring a larger chuck capacity. Typical applications include drilling oversized clearance holes in steel plate, structural steel, and similar materials in shop or field settings. The three-flat shank geometry prevents rotation in the chuck under the high torque loads associated with large-diameter drilling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e49\/64-inch cutting diameter (0.7656 inches decimal) for large clearance hole applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability in metal drilling\u003c\/li\u003e\n  \u003cli\u003eBlack oxide straw finish reduces surface friction and provides mild corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle for general-purpose material entry\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch reduced shank with three flats prevents chuck slippage under high torque\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length with 3-inch flute length for chip evacuation in deep holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose reduced shank drill bit compatible with any 1\/2-inch capacity drill press chuck or handheld drill driver accepting a reduced-shank bit with a three-flat, 1\/2-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists and maintenance mechanics using a drill press or handheld drill with a 1\/2-inch chuck. Secure all three flats firmly in the chuck jaws before drilling to prevent rotation under load. Use cutting fluid when drilling through ferrous metals to extend bit life and reduce heat buildup. Ensure the workpiece is clamped securely before beginning the cut; never hold the workpiece by hand when using large-diameter bits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 49\/64 inch (0.7656 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Reduced with Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Black Oxide Straw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 623\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.45 pounds\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: TITAN USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SD94749\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51755689836850,"sku":"SD94749","price":61.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60d3ebfb2b344bace007252abd939696_8a835c4c-15d8-4eb1-8bf2-4a30fdee6076.jpg?v=1788958166","url":"https:\/\/voomisupply.com\/products\/titan-usa-sd94749-reduced-shank-drill-bit-49-64-inch-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
