The bit measures 1-5\/16 inches (1.3125 inches) in diameter with a 1\/2-inch straight-cylindrical shank, allowing it to be chucked in standard 1\/2-inch drill presses and portable drills despite its large cutting diameter. Constructed from high speed steel (HSS) with a bright, uncoated finish, the 5999911 delivers reliable performance in ferrous metals, aluminum, copper, and similar workpiece materials. The 118-degree standard point angle suits everyday drilling applications without requiring special point geometry.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for metalworking shops, maintenance and repair operations, fabrication environments, and trade professionals who drill large-diameter holes in steel, pipe, plate, or structural members. The reduced shank design is the key feature here: it extends the usable range of a standard 1\/2-inch chuck to cut holes well beyond what a full-shank bit of equivalent diameter would require. The 3-inch flute length supports drilling depths up to 3 inches, and the 6-inch overall length provides clearance for most drill press setups and hand-drill applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-5\/16-inch (1.3125-inch) cutting diameter with 1\/2-inch reduced shank for use in standard chucks\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across ferrous and non-ferrous workpiece materials\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with right-hand spiral flutes for general-purpose cutting\u003c\/li\u003e\n  \u003cli\u003e3-inch flute length with maximum drilling depth of 3 inches\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length; bright, uncoated finish\u003c\/li\u003e\n  \u003cli\u003eSeries R56; meets ANSI standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any drill press or hand drill equipped with a 1\/2-inch chuck.

Power down and de-energize the drill press or tool before changing bits. Clamp workpieces securely to prevent rotation during large-diameter drilling. Follow applicable shop safety protocols and use appropriate eye and hand protection when drilling metal.\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3 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\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: Bright\/Uncoated\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: Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R56\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5999911\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51709967499570,"sku":"5999911","price":208.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac656fd05387c1c38e5c0fc9d50ceb12.jpg?v=1788462642","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999911-reduced-shank-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
