The bit features a 43\/64 inch (0.6719 inch decimal) cutting diameter paired with a 1\/2 inch reduced shank, allowing it to fit standard 1\/2 inch drill chucks while cutting a larger bore diameter. Manufactured from high-speed steel (HSS), the bit handles moderate heat buildup during drilling without losing edge hardness. The 118-degree split or conventional point angle is a general-purpose geometry suited to a wide range of materials. A bright, uncoated finish keeps material cost low on a bit intended for general shop and field use.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is well suited for plumbers, HVAC installers, electricians, and general contractors who need to bore larger through-holes in structural members, sheet metal, or framing. The reduced shank design solves a common field problem: running a sub-1-inch large-diameter bit through a standard 1\/2 inch keyless or keyed chuck without stepping up to a larger drill or right-angle attachment. Typical applications include boring holes for pipe and conduit pass-throughs, anchor bolt clearances, and fixture mounting in both residential and light commercial work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e43\/64 inch cutting diameter (0.6719 inch decimal) for larger-bore applications with a standard 1\/2 inch chuck\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction resists heat and wear across metal, wood, and plastic substrates\u003c\/li\u003e\n  \u003cli\u003e118-degree point angle provides a general-purpose cutting geometry suitable for most trade drilling tasks\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish on Series 625 — no coating buildup to affect hole tolerance\u003c\/li\u003e\n  \u003cli\u003e3 inch flute length with 6 inch overall length suits medium-depth through-holes in framing and structural members\u003c\/li\u003e\n  \u003cli\u003eTwo-flute design promotes efficient chip evacuation during drilling\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 keyed or keyless drill chuck.

When drilling metal, use appropriate cutting fluid or lubricant to extend bit life and improve hole quality. Always wear appropriate eye protection and secure the workpiece before drilling. Follow applicable OSHA hand and power tool safety requirements for the job site.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 43\/64 inch (0.6719 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: 0.38 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: SD91443\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51730587517234,"sku":"SD91443","price":48.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ecd0cd614ceac8558e46cc4c268ebd89_5197f39d-f3bc-4f91-a0b2-daa4076b8f1a.jpg?v=1788719995","url":"https:\/\/voomisupply.com\/products\/titan-usa-sd91443-reduced-shank-drill-bit-43-64-inch-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
