Built from high-speed steel (HSS), it delivers reliable hardness and heat resistance under continuous cutting loads. The bit features a 45\/64 inch (0.7031 inch decimal) cutting diameter paired with a 1\/2 inch reduced shank, allowing it to seat in standard 1\/2 inch chucks without requiring a larger chuck size. The 118-degree split-point angle promotes clean entry and reduces walking on flat surfaces. With a 6 inch overall length and 3 inch flute length, it provides adequate reach for most structural and mechanical drilling applications.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in machine shops, maintenance facilities, and fabrication environments where larger-diameter holes are required through steel plate, structural members, or similar workpieces. The reduced shank design makes it compatible with drill presses, magnetic base drills, and portable electric drills equipped with a standard 1\/2 inch chuck. It is a practical choice for millwrights, machinists, pipefitters, and general maintenance mechanics who need a large-diameter bit without upgrading to a larger chuck.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45\/64 inch cutting diameter (0.7031 inch decimal) for large-bore hole applications\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch reduced shank fits standard 1\/2 inch drill chucks\u003c\/li\u003e\n  \u003cli\u003e118-degree point angle for general-purpose drilling in metal and similar materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction resists heat buildup during extended cuts\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — compatible with cutting oils and coolants\u003c\/li\u003e\n  \u003cli\u003e2-flute design promotes chip evacuation through the full 3 inch flute length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose reduced shank drill bit for use with 1\/2 inch keyless or keyed chucks on drill presses and handheld electric drills.

Ensure the workpiece is clamped or fixtured to prevent rotation during drilling. Use an appropriate cutting fluid or oil when drilling ferrous metals to extend bit life and reduce heat. Inspect the cutting edges for wear before each use and replace when the tip shows signs of chipping or dulling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 45\/64 inch (0.7031 inch)\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: 0.39 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: SD91445\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51728685695282,"sku":"SD91445","price":48.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2464d15e45491e628083f15c2c3386c.jpg?v=1788694984","url":"https:\/\/voomisupply.com\/products\/titan-usa-sd91445-reduced-shank-drill-bit-45-64-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
