It carries a 47\/64 inch (0.7344 inch decimal) cutting diameter with a 1\/2 inch straight-cylindrical shank, allowing it to fit standard 1\/2 inch chucks even though the cutting diameter is larger. The tool is manufactured from high speed steel and features a 118-degree standard point angle suited for general-purpose drilling across a range of workpiece materials. Two spiral flutes in a regular helix configuration clear chips efficiently during the cut. A coated finish helps extend cutting life in everyday service conditions.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for general-purpose portable drilling use by machinists, pipefitters, ironworkers, electricians, and maintenance technicians. The reduced shank design makes it practical for operators whose drill chuck capacity tops out at 1\/2 inch but who need to cut holes larger than that shank size. Rated for primary use in wood and secondary use in alloy steel, carbon steel, and cast iron, it covers the mix of materials common to mechanical, structural, and general fabrication work. Right-hand cutting direction is standard for conventional drill operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e47\/64 inch cutting diameter (0.7344 inch decimal) with 1\/2 inch reduced shank for standard chuck compatibility\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry into steel, cast iron, and wood\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eTwo-flute regular spiral design promotes chip evacuation during portable drilling\u003c\/li\u003e\n  \u003cli\u003eCoated finish for added wear resistance in production and field use\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, Series 190 — diameter tolerance held to +0.0000 to -0.0012 inches\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 1\/2 inch drill chucks.

De-energize and lock out any stationary drilling equipment before changing bits. Use appropriate cutting fluid when drilling ferrous metals to manage heat buildup and extend tool life. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 47\/64 inch (0.7344 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inch (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.2500 inches (57.15 mm)\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: 3-1\/8 inches\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0012 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Wood\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Cast Iron, Wood\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Portable Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 190\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant\u003c\/strong\u003e: No\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: 55447\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51727465873714,"sku":"55447","price":54.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ee0b882ebf916b1f14006f27c6107d7.jpg?v=1788678227","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-55447-reduced-shank-drill-bit-47-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
