It features a 19\/32-inch cutting diameter (0.5938 inches decimal) with a 1\/2-inch Weldon shank, allowing it to seat securely in standard 1\/2-inch chucks and drill motors. The 118-degree split point geometry promotes accurate starting without center-punching and reduces walking on flat stock. Constructed from high speed steel with a coated finish, this bit handles the cutting heat and abrasion typical in production and field drilling tasks. Licensed electricians, pipefitters, ironworkers, and general maintenance technicians commonly reach for this size when drilling knockouts, conduit holes, and clearance holes through structural members.\u003c\/p\u003e\n\u003cp\u003eThe 52438 is built around the Series 190F platform, a general-purpose reduced shank line suited for portable drill applications. The 1\/2-inch Weldon shank with three flats prevents rotation under load, which matters when drilling through alloy steel, carbon steel, or cast iron. At 6 inches overall length with a 3-1\/8-inch flute length, it clears chips efficiently in moderate-depth holes without excessive deflection. Primary listed workpiece material is wood, with secondary materials including alloy steel, carbon steel, and cast iron, making it a versatile choice across trade applications where one bit needs to handle mixed-material structures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e19\/32-inch cutting diameter (0.5938 inches decimal) with tight tolerance of +0.0000 to -0.0012 inches\u003c\/li\u003e\n  \u003cli\u003e118-degree split point reduces walking and improves bite on flat and curved surfaces\u003c\/li\u003e\n  \u003cli\u003eWeldon shank with 3 flats locks against chuck rotation under high-torque portable drilling\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute geometry promotes consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eReduced shank design allows 19\/32-inch cutting diameter in a standard 1\/2-inch chuck\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use bit compatible with standard 1\/2-inch Weldon-style chucks and portable drill motors used across HVAC, electrical, plumbing, and general construction trades.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified tradespeople familiar with portable drilling equipment and appropriate PPE requirements. Secure the Weldon shank fully into the chuck and verify all flat-engagement set screws are tightened before operation. Power down and disconnect the drill from its power source before changing bits. Do not exceed the drill motor manufacturer's rated RPM for this bit diameter, and use appropriate cutting fluid when drilling through hardened alloy or cast iron stock to extend bit life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 19\/32 inches (0.5938 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 (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 -0.0012 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\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\u003eCoolant Required\u003c\/strong\u003e: No\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: 0.3 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: 52438\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51754249814322,"sku":"52438","price":47.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a09e90d707075c064bf08301be23d2c_fa893496-8a5f-4724-93cd-00c4bd910e2b.jpg?v=1788944097","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-52438-reduced-shank-drill-bit-19-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
