Manufactured from high-speed steel (HSS) with a bright uncoated finish, it features a 13\/16 inch (0.8125 inch) diameter, a standard 118-degree split point, and a right-hand cutting direction. The shorter overall length of 5.25 inches provides added rigidity compared to jobber-length bits, reducing deflection in drill press and CNC drilling applications. Two spiral flutes with a web-thinned parallel web configuration improve chip evacuation and reduce thrust force at entry. Licensed HVAC techs, machinists, and trade professionals reach for this bit when hole accuracy and tool life in alloy and aluminum stock are the priority.\u003c\/p\u003e\n\u003cp\u003eThe C04647 is suited for drilling alloy steel, aluminum, and similar materials in both manual and machine-fed operations. Its straight cylindrical shank fits standard drill chucks without adapters. The stub length format makes it a practical choice for tight-clearance drilling, drill press work, and screw machine setups where a longer jobber bit would introduce unwanted flex. It conforms to ASME B94.11M and ANSI specification standards, making it appropriate for shop environments where dimensional compliance is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e13\/16 inch (0.8125 inch) diameter with a tolerance of +0.0000 to -0.0012 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned parallel web for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides heat resistance for general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003eScrew machine (short) length at 5.25 inches OAL increases rigidity and reduces deflection\u003c\/li\u003e\n  \u003cli\u003eTwo spiral flutes with right-hand cut for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and ANSI dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose screw machine length drill bit compatible with standard drill chucks accepting a 0.8125 inch straight cylindrical shank, suitable for alloy steel and aluminum workpieces in drill press, lathe, and screw machine applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this bit is performed by machinists, tool and die technicians, or qualified trade professionals operating drill presses, lathes, or screw machines. Secure the straight shank fully in the chuck before operation and verify chuck key is removed before powering the machine. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting this bit does not have through-coolant capability. Inspect the cutting edges for wear or chipping before each use and replace if the point geometry is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 13\/16 inch (0.8125 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.25 inches (133.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.875 inches (47.63 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.8125 inch straight cylindrical\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel, web-thinned\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Aluminum\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\u003eDrill Length Type\u003c\/strong\u003e: Short (Screw Machine)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2120\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, ANSI\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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C04647\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51702381543730,"sku":"C04647","price":88.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f95a5656d0a67fe04fb52b759c06602b.jpg?v=1788410537","url":"https:\/\/voomisupply.com\/products\/cleveland-c04647-screw-machine-drill-bit-13-16-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
