The bit measures 0.5469 inches in diameter with a 12-inch overall length and a 9-inch spiral flute length, giving it the reach needed to bore through thick sections or deep cavities that standard-length bits cannot access. The 118-degree notched point with web thinning reduces thrust and improves centering on hard materials. An oxide finish provides light corrosion resistance during storage and use. This bit is part of the Series 120X line, built for general-purpose production and maintenance drilling.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for right-hand cutting in cast iron and steel workpieces where extended reach is required. Typical applications include structural fabrication, equipment maintenance, and any setup where a standard-length bit lacks the flute length to clear chips through a deep bore. The straight-cylindrical shank fits standard drill chucks across a range of drill press, magnetic drill, and hand-drill setups. It is used by machinists, millwrights, pipefitters, and maintenance technicians working in industrial and commercial environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtra length design: 12-inch OAL and 9-inch flute length for deep-reach drilling\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability in cast iron and steel applications\u003c\/li\u003e\n  \u003cli\u003e118-degree notched point with web thinning to reduce entry thrust and improve accuracy\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration with regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eOxide finish for light corrosion protection during storage and service\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with 0.5469-inch shank diameter for broad chuck compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks accepting a 0.5469-inch straight-cylindrical shank.

Secure the shank fully in the chuck jaws and verify concentricity before operation to avoid runout that can deflect a long bit. For deep-hole drilling, retract the bit periodically to clear chips and prevent heat buildup; cutting fluid is recommended for steel workpieces. Follow applicable OSHA machine guarding and PPE requirements when operating drill presses or magnetic drills.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5469 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5469 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 3 inches\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: Oxide\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: Notched\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0012 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Long Reach Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 120X\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: California Prop 65\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: 50591\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51748763566386,"sku":"50591","price":100.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a9d9c629d17e1563f51ca8c920fc284_af9b758f-835b-4beb-9a0c-dd87c478b7d0.jpg?v=1788897989","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-50591-extra-length-drill-bit-0-5469in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
