Built from high speed steel (HSS) with an oxide coating, it delivers reliable performance in production and maintenance drilling applications. The bit measures 9\/64 inch (0.1406 inch) in diameter with a 118-degree split point that self-centers on contact and reduces walking at the start of a hole. Overall length is 2-7\/8 inches with a 1-3\/4 inch flute length. The straight cylindrical shank and regular spiral flute geometry make it compatible with standard drill chucks. Machinists, maintenance technicians, and general tradespeople use this bit for metal, composite, and light-alloy work.\u003c\/p\u003e\n\u003cp\u003eThe 57209 is suited for drilling in magnesium alloy and similar light metals, as well as general shop and field applications. The two-flute spiral design promotes chip evacuation during through-hole drilling. The web-thinned, tapered web configuration reduces thrust required at the drill point, which is especially useful when working with thinner or softer materials. This bit is sold individually and is part of the Chicago-Latrobe Series 150K, a general-purpose HSS drill line intended for everyday production and repair use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction with oxide coating for corrosion resistance and reduced friction\u003c\/li\u003e\n  \u003cli\u003e118-degree split point reduces walking and lowers entry thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web for easier penetration in light alloys and soft metals\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, two-flute design promotes consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard 3-jaw drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of -0.0007 to 0.0000 inch for accurate hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement jobber drill bit in the Series 150K line, compatible with any standard drill chuck accepting a straight cylindrical shank of 0.1406 inch diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a calibrated drill press, hand drill, or drill driver with the chuck tightened securely before operation. Always wear appropriate eye protection and secure the workpiece before drilling. When drilling magnesium alloy or other reactive light metals, follow applicable shop safety procedures for controlling fine chips and swarf. No coolant-through capability; apply cutting fluid externally when drilling harder materials 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: 9\/64 inch (0.1406 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1406 inch (3.57 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1250 inches (28.57 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Magnesium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 57209\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51738714669362,"sku":"57209","price":38.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ff36234c9b89b003efad7b6cbbff808_f4d49506-09b1-49e7-9af2-fbb1c004fbf5.jpg?v=1788803286","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-57209-9-64-inch-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
