The bit measures 55\/64 inch (0.8594 inch decimal) in cutting diameter and runs a 1\/2 inch reduced shank, allowing it to be chucked in standard 1\/2 inch drill presses and hand drills without requiring a larger-capacity chuck. Overall length is 6 inches, with a 3 inch flute length. The 118-degree split-point angle provides reliable self-centering on flat and curved surfaces. Constructed from high-speed steel with a bright, uncoated finish, this bit is suited for general-purpose drilling in lower-heat applications.\u003c\/p\u003e\n\u003cp\u003eThe SD91455 is appropriate for metal fabrication shops, HVAC sheet-metal work, plumbing rough-in, electrical conduit work, and general mechanical assembly. The reduced shank design is specifically intended for situations where a large-diameter cutting edge is needed but only a 1\/2 inch chuck is available on the drill press or portable drill. It is sold individually and fits naturally into a Series 625 tool kit or standalone use by a journeyman or apprentice tech needing a reliable, single-purpose bit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e55\/64 inch cutting diameter (0.8594 inch decimal) for large-bore applications\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch reduced shank fits standard 1\/2 inch chucks without upsizing equipment\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle for self-centering on flat and curved surfaces\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles demanding drilling cycles\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose and lower-heat drilling\u003c\/li\u003e\n  \u003cli\u003e3 inch flute length with 6 inch overall length for reach and chip clearance\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 keyless or keyed drill chuck on bench-top drill presses or portable hand drills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by any qualified tradesperson or machinist with a 1\/2 inch drill press or hand drill. Secure the workpiece firmly before drilling and confirm chuck jaws are fully tightened on the reduced shank before starting the spindle. Use appropriate cutting fluid or lubricant when drilling ferrous metals to reduce heat buildup and extend bit life. Wear ANSI-rated eye protection at all times during drilling operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 55\/64 inch (0.8594 inch 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\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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 625\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.53 pounds\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: TITAN USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SD91455\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51732772716850,"sku":"SD91455","price":62.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ecd0cd614ceac8558e46cc4c268ebd89_fe5b5cde-d085-46f8-9c75-2b93c2e318cc.jpg?v=1788746606","url":"https:\/\/voomisupply.com\/products\/titan-usa-sd91455-reduced-shank-drill-bit-55-64-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
