The bit measures 1-5\/32 inches (1.1562 inches decimal) in cutting diameter with a 1\/2-inch Weldon shank, making it compatible with standard 1\/2-inch chucks while delivering a larger bore diameter. The 118-degree split point geometry promotes clean entry and reduces walking on startup. Overall length is 6 inches with a 3-1\/8-inch flute length, and the coated finish provides added wear resistance during extended use. This is a Series 190F bit suited for trades that require oversized hole drilling without upgrading chuck capacity.\u003c\/p\u003e\n\u003cp\u003eThe 52474 is designed for portable drilling operations across a range of materials including wood, alloy steel, carbon steel, and cast iron. The right-hand spiral flute with regular helix efficiently clears chips during through-hole drilling. With a Weldon shank featuring three flats and a 2.25-inch shank length, the bit seats securely in side-locking tool holders, reducing slip under load. This makes it practical for HVAC technicians, pipefitters, electricians, and general contractors who need to drill large-diameter holes through structural materials in the field.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-5\/32-inch cutting diameter with reduced 1\/2-inch Weldon shank for standard chuck compatibility\u003c\/li\u003e\n  \u003cli\u003e118-degree split point reduces thrust and prevents bit walking on entry\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles wood, carbon steel, alloy steel, and cast iron\u003c\/li\u003e\n  \u003cli\u003eThree-flat Weldon shank resists rotational slip in side-lock holders\u003c\/li\u003e\n  \u003cli\u003eCoated finish for improved wear resistance and heat dissipation\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral flute for efficient chip evacuation during portable 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 1\/2-inch Weldon-style side-lock tool holders and standard 1\/2-inch keyed or keyless chucks used in portable and bench drilling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified tradesperson familiar with portable drilling equipment and proper tool-holder torquing procedures. Secure the Weldon shank fully into the side-lock holder before engaging set screws to prevent axial pullout under load. Always wear appropriate eye protection and secure the workpiece before drilling. Follow applicable workplace safety codes and equipment manufacturer guidelines for drill press and portable drill operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1-5\/32 inches (1.1562 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches \/ 12.70 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\u003eShank Length\u003c\/strong\u003e: 2.25 inches (57.15 mm)\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: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 3\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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 -0.0015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Portable Drilling\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\u003eSeries\u003c\/strong\u003e: 190F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 52474\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51735025975602,"sku":"52474","price":126.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a09e90d707075c064bf08301be23d2c_c5abc06f-e66b-438d-88f0-d4a0f2710101.jpg?v=1788769367","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-52474-reduced-shank-drill-bit-1-5-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
