It features a 1-29\/64 inch (1.4531 inch decimal) cutting diameter with a 1\/2 inch Weldon shank, allowing it to fit standard 1\/2 inch chucks while boring oversized holes. The 118-degree standard point angle provides reliable entry on flat and curved workpiece surfaces. Built from high speed steel with a coated finish, the 52493 delivers solid wear resistance during sustained drilling operations. Two spiral flutes with a regular helix evacuate chips efficiently throughout the cut. Licensed trades and industrial maintenance personnel are the primary installers of this tool.\u003c\/p\u003e\n\u003cp\u003eThe 52493 is suited for portable drilling applications across a range of workpiece materials including wood, carbon steel, alloy steel, and cast iron. The Weldon shank with three flats resists bit slippage under torque loads, making it a practical choice for handheld drill motors and drill press setups where chuck grip on a large-diameter bit is a concern. The reduced shank design expands the effective drilling capacity of 1\/2 inch drive tools beyond their nominal chuck rating.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-29\/64 inch cutting diameter (1.4531 inch decimal) for oversized hole applications\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch Weldon shank with 3 flats prevents slippage under high torque\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry on flat and curved surfaces\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n  \u003cli\u003e2-flute regular spiral design promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eNo coolant required — compatible with dry drilling operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/2 inch Weldon-style tool holders and chucks.

Confirm the drill motor or press is rated for the torque demands of a 1-29\/64 inch diameter cut in the target material. Power down and de-energize any machinery completely before changing bits. Follow applicable OSHA and ANSI safety standards 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 Size\u003c\/strong\u003e: 1-29\/64 inches (1.4531 inches 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: 2.2500 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 Helix)\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 -0.0015 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\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: 1.3 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: 52493\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51733580546354,"sku":"52493","price":257.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a09e90d707075c064bf08301be23d2c_ea72c012-2830-49cb-9301-ab8331850c5b.jpg?v=1788756542","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-52493-reduced-shank-drill-bit-1-29-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
