Built from M42 cobalt steel, it holds its edge under heat and friction better than standard HSS bits. The 135-degree split point starts without walking and requires less thrust to penetrate. At 1-13\/16 inches overall length with a 13\/16-inch flute, it fits close-quarters drilling applications where a jobber-length bit will not clear. Machinists, tool-and-die techs, and production drillers working cast iron and steel reach for this grade when material hardness or heat buildup would wear out a standard bit faster than acceptable.\u003c\/p\u003e\n\u003cp\u003eSeries 559 screw machine bits are a standard choice in CNC and manual lathe operations, screw machine setups, and short-reach drill press work. The reduced flute length provides rigidity that limits deflection when drilling through cast iron or structural steel. The straight-cylindrical shank fits standard drill chucks and collet holders without modification. This bit is sold individually and is appropriate for industrial shop environments, job-site metalworking, and maintenance operations where heavy-duty tooling is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction handles elevated cutting temperatures in hard ferrous materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point self-centers on entry and reduces axial thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web lowers cutting resistance and improves chip clearance\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body provides extra rigidity and reduces bit deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute evacuates chips efficiently during through-hole drilling\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.0000 to -0.0005 inches for precise hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling cast iron and steel.

Always secure the workpiece before drilling and ensure the spindle is fully stopped before changing tooling. Use appropriate cutting fluid for cast iron and steel to extend tool life. Inspect the cutting edges before each use and replace if chipping or heat discoloration is present.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 7\/64 inch (0.1094 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13\/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\u003eTool Material\u003c\/strong\u003e: M42 Cobalt\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\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\u003eCoolant Through\u003c\/strong\u003e: No\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: 50804\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51730545606962,"sku":"50804","price":45.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5d92ffa42f8cc5bf33a2250f5ce0e7b_9b62776f-12d0-4ac1-b95f-7672bae62784.jpg?v=1788719337","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-50804-screw-machine-drill-bit-7-64-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
