Built from high speed steel with a coated finish, it features a 1-5\/16 inch cutting diameter paired with a 1\/2 inch Weldon shank, allowing it to run in standard 1\/2 inch drill chucks while cutting oversize holes. The 118-degree standard point angle delivers clean entry across a range of workpiece materials. At 6 inches overall length with a 3-1\/8 inch flute length, this bit suits both bench drilling and in-the-field portable applications. Installation and use is handled by machinists, pipefitters, ironworkers, and general tradespeople requiring larger-diameter bored holes without a full-size chuck.\u003c\/p\u003e\n\u003cp\u003eThe 52484 is suited for portable drilling in residential and commercial trade work. Compatible workpiece materials include wood, alloy steel, carbon steel, and cast iron. The Weldon shank with three flats resists bit slippage under torque, making it well matched for high-torque portable drills and right-angle drill applications common in plumbing rough-in, structural steel work, and HVAC duct framing. The right-hand spiral flute geometry clears chips efficiently during through-hole drilling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-5\/16 inch cutting diameter with diameter tolerance of +0.0000 to -0.0015 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003eWeldon shank with 3 flats prevents rotation in chuck under heavy torque loads\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry across steel, cast iron, and wood\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles intermittent heat buildup in portable drilling scenarios\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends cutting edge life compared to uncoated HSS\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute design promotes efficient chip evacuation during through-hole cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 1\/2 inch Weldon-style drill chucks and compatible portable drilling equipment.

Always wear appropriate eye protection and secure the workpiece before drilling. Reduce feed pressure as the bit exits the workpiece to prevent grab or material tear-out. For steel applications, use appropriate cutting fluid where conditions allow to extend bit life.\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\/16 inches (1.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\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: 2.2500 inches\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\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\u003eSeries\u003c\/strong\u003e: 190F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 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: 52484\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51749509169458,"sku":"52484","price":207.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a09e90d707075c064bf08301be23d2c_a5582495-6f9d-4da9-bcbf-0504254ad98a.jpg?v=1788907009","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-52484-reduced-shank-drill-bit-1-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
