Built from high speed steel (HSS) with a coated finish, it offers a 13\/16 inch (0.8125 inch decimal) cutting diameter paired with a 1\/2 inch straight-cylindrical shank, allowing it to chuck into standard 1\/2 inch drill chucks even at a larger cutting diameter. The 118-degree standard point angle suits a broad range of common workpiece materials. Overall length is 6 inches with a 3-1\/8 inch flute length, keeping the bit compact while providing adequate chip clearance for typical depth requirements.\u003c\/p\u003e\u003cp\u003eThis bit is designed for portable drilling applications across residential, commercial, and light industrial settings. The reduced shank configuration makes it practical when a larger bore diameter is needed but only a 1\/2 inch chuck is available — a common situation for field crews, maintenance technicians, and tradespeople working off cordless or corded drills rather than dedicated drill presses. Suitable workpiece materials include wood, alloy steel, carbon steel, and cast iron, making it a versatile single-bit solution for mixed-material job sites.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e13\/16 inch cutting diameter with a reduced 1\/2 inch straight-cylindrical shank for use in standard 1\/2 inch chucks\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose drilling across multiple materials\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability in metal, wood, and cast iron\u003c\/li\u003e\n\u003cli\u003eCoated finish to reduce friction and extend cutting life\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute design with 2 regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0012 inches for consistent bore sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose reduced shank drill bit suitable for use with any 1\/2 inch chuck portable drill.

Ensure the drill is powered off and the chuck is fully released before bit changes. When drilling metals, use appropriate cutting fluid or lubricant to manage heat buildup and extend bit life, even though this bit is rated for dry use. Follow applicable OSHA and site-safety guidelines for portable drilling operations, including securing the workpiece and wearing appropriate eye protection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 13\/16 inch (0.8125 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.25 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: 3.125 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: 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 -0.0012 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: 190\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Required\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 55452\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51737220514098,"sku":"55452","price":60.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/24532f93a0466472107914b6f770790c.jpg?v=1788785738","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-55452-reduced-shank-drill-bit-13-16-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
