The bit measures 45\/64 inch (0.7031 inch decimal) in cutting diameter with a 1\/2 inch Weldon shank, making it compatible with standard 1\/2 inch chuck equipment. Constructed from high speed steel with a coated finish, it features a 118-degree split point that improves bite on entry and reduces walking on smooth surfaces. The Series 190F designation places it in a general-purpose line suited for trade and industrial use. Overall length is 6 inches with a 3-1\/8 inch flute length and a right-hand spiral cut.\u003c\/p\u003e\n\u003cp\u003eThis bit is built for portable drilling scenarios where a reduced shank allows a larger cutting diameter to be run through a 1\/2 inch chuck. The Weldon shank with three flats resists rotational slippage under load, which matters on harder workpiece materials such as alloy steel and cast iron. Typical users include electricians, pipefitters, ironworkers, and general contractors who need an oversized hole in structural or mechanical assemblies without switching to a larger drill. The regular spiral flute geometry clears chips efficiently across all listed workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45\/64 inch cutting diameter (0.7031 inch decimal) with diameter tolerance of +0.0000 to -0.0012 inches\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch Weldon shank with three flats prevents slippage in chuck during high-torque drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree split point improves self-centering and reduces thrust required at entry\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for general-purpose durability\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, two-flute regular spiral geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eSuitable for wood, alloy steel, carbon steel, and cast iron workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in portable drills and drill presses equipped with a 1\/2 inch chuck.

Secure the Weldon shank fully in the chuck or Weldon-style holder so all three flats are engaged before applying power. Wear appropriate eye protection and secure the workpiece before drilling. Follow applicable OSHA and tool-manufacturer guidelines for portable drilling operations, including proper RPM selection for the workpiece material and bit diameter.\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 decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch \/ 12.70 mm)\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\u003eShank Length\u003c\/strong\u003e: 2.25 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: Split\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\u003eDrill Length Type\u003c\/strong\u003e: Reduced Shank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 190F\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Wood\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Cast Iron, Wood\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\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: 52445\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51747564650802,"sku":"52445","price":54.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a09e90d707075c064bf08301be23d2c_4820a54c-8fa4-4c17-8e74-029541be745c.jpg?v=1788882660","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-52445-reduced-shank-drill-bit-45-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
