Built from high speed steel with a bright uncoated finish, this bit measures 17\/64 inch (0.2656 inches) in diameter and carries a 118-degree standard point angle. The two-flute spiral design with web-thinned geometry reduces thrust and improves chip evacuation. The straight cylindrical shank seats cleanly in standard drill chucks. Overall length is 2-5\/8 inches with a flute length of 1-7\/16 inches. Machinists, tool-and-die workers, and maintenance mechanics install this bit in drill presses, CNC machines, and hand-held power drills for general-purpose metal removal.\u003c\/p\u003e\u003cp\u003eThe 48517 is rated for use on cast iron, non-ferrous metals, and steel. Its screw machine length body — shorter than jobber length — provides added rigidity and reduced deflection in close-tolerance drilling setups. This makes it well suited to production environments where repeatable hole location and diameter consistency are critical. The diameter tolerance is held to +0.0000 to -0.0010 inches, supporting accurate fit-up for tapped holes, reamed bores, and press-fit applications. It meets ISO standards for drill geometry and dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e17\/64 inch diameter with tight tolerance of +0.0000 to -0.0010 inches for consistent hole sizing\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle suitable for general-purpose metal drilling\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel web construction reduces cutting thrust and entry force\u003c\/li\u003e\n\u003cli\u003eScrew machine length body adds rigidity and minimizes deflection versus jobber-length bits\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with bright uncoated finish — no coating to chip or peel\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, two-flute spiral flute design for efficient chip removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe 48517 belongs to the Chicago-Latrobe Series 157 screw machine drill line and is designed for general-purpose drilling in cast iron, non-ferrous metal, and steel workpieces using any standard drill chuck that accepts a straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall in a drill press, lathe tailstock, or CNC spindle using a properly sized collet or drill chuck rated for the shank diameter. Secure the workpiece fully before drilling and confirm spindle speed is appropriate for the material and bit diameter. Coolant-through is not supported by this bit; use external cutting fluid on steel and cast iron where needed to extend tool life. Inspect the point geometry before use — a damaged or off-center point will cause oversized or wandering holes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 17\/64 inch (0.2656 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-7\/16 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\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: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 157\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0308 pounds\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: 48517\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51752497119538,"sku":"48517","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6fab4ed6c02ecc288dc1e4eee24eef3.jpg?v=1788928625","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48517-screw-machine-drill-bit-17-64-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
