Built to Series 559 standards, it measures 17\/64 inch (0.2656 inches) in diameter with an overall length of 2-5\/8 inches and a flute length of 1-7\/16 inches. The 135-degree split point reduces walking and lowers thrust required at entry. Web thinning improves chip clearance in tough ferrous materials. The M42 cobalt steel construction handles elevated cutting temperatures without losing hardness, making it suited for production environments where bits run hot.\u003c\/p\u003e\u003cp\u003eThis bit is built for screw machine and short-hole drilling applications in metal fabrication, maintenance, and production machining. The straight-cylindrical shank seats in standard drill chucks, CNC turrets, and screw machine spindles without adapter collars. Primary workpiece materials are cast iron and steel. The regular spiral with parallel web configuration gives consistent chip evacuation in through-holes and blind holes alike. This is a single-bit package intended for industrial and trade use by machinists, pipefitters, and maintenance technicians who need a reliable stubby bit for tight-clearance or high-cycle work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction resists heat buildup during extended cuts in ferrous metals\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust and minimizes drill walking on entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel web design improves chip flow and reduces torque demand\u003c\/li\u003e\n\u003cli\u003eScrew machine length body (2-5\/8 inches overall) fits tight spaces and short-travel spindles\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 2-flute spiral configuration for standard forward-feed drilling\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0010 inches for controlled-fit hole sizing\u003c\/li\u003e\n\u003cli\u003eISO standards compliance for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and direct-use drill bit for standard drill chucks, CNC turrets, and screw machine spindles accepting straight-cylindrical shank tooling in the 17\/64 inch diameter class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or qualified maintenance technician should secure the shank fully in a properly sized collet or chuck before operation. Ensure the machine spindle is fully stopped and locked out before changing or inspecting the bit. Use appropriate cutting fluid or coolant when drilling steel at production feed rates to extend tool life, noting that this bit does not support internal coolant-through delivery. Follow shop safety codes and applicable OSHA machine-guarding requirements when operating drill presses, lathes, or CNC equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\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: 135 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\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\u003eTool Material\u003c\/strong\u003e: M42 Cobalt Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 559\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\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: 50814\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51732709048626,"sku":"50814","price":15.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5d92ffa42f8cc5bf33a2250f5ce0e7b_dbc20d38-d3ea-4505-a487-2113188c1a33.jpg?v=1788745919","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-50814-cobalt-screw-machine-drill-bit-17-64","provider":"Voomi Supply","version":"1.0","type":"link"}
