Built from high-speed steel (HSS) with a bright, uncoated finish, this bit features a 9\/16 inch diameter, a standard 118-degree split point, and a web-thinned tip that reduces thrust and improves centering at the start of a cut. The short overall length of 4 inches and straight-cylindrical shank make it well-suited for use in drill presses, CNC machining centers, lathes, and screw machine setups where a stub-length configuration reduces deflection and chatter.\u003c\/p\u003e\u003cp\u003eThis bit is intended for general-purpose drilling in alloy steel and aluminum in both light manufacturing and job-shop environments. The 2-flute right-hand spiral design provides efficient chip evacuation during through-hole and blind-hole operations. Machinists, tool-and-die makers, and maintenance mechanics working in metal fabrication, aerospace component production, or general industrial settings will find this bit appropriate for standard duty cycle applications across those materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e9\/16 inch (0.5625 inch) diameter with a diameter tolerance of +0.0000 to -0.0012 inches for consistent hole sizing\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web thinning for reduced entry thrust and improved self-centering\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides heat resistance and edge retention suitable for alloy and aluminum stock\u003c\/li\u003e\n\u003cli\u003eShort screw machine length — 4 inches overall, 2.5 inch flute length — minimizes deflection in close-clearance setups\u003c\/li\u003e\n\u003cli\u003eRight-hand, 2-flute regular spiral with parallel web configuration for reliable chip clearance\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M standards for drill bit geometry and dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or production-stock drill bit for use in screw machines, drill presses, CNC lathes, and milling machines accepting a 0.5625 inch straight-cylindrical shank.

Secure the shank fully in a properly sized collet, chuck, or tool holder before operation, and verify runout before drilling. Always power down and de-energize the machine before changing bits. Do not exceed the recommended feed and speed parameters for the workpiece material and machine type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9\/16 inches (0.5625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5625 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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\u003eDrill Length Type\u003c\/strong\u003e: Short (Screw Machine Length)\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 -0.0012 inches\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\u003eSeries\u003c\/strong\u003e: 2120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B94.11M\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C04612\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51716945641778,"sku":"C04612","price":53.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b867a19f90aac5b69a0ed1110aa0b6c0.jpg?v=1788533788","url":"https:\/\/voomisupply.com\/products\/cleveland-c04612-screw-machine-drill-bit-9-16-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
