Built from high-speed steel (HSS) with a bright\/uncoated finish, this bit measures 43\/64 inches (0.6719 inches) in diameter and runs 4.625 inches overall. The 118-degree standard point angle and web-thinned tip reduce thrust and improve centering at entry. The straight-cylindrical shank seats securely in standard drill chucks and machine spindles. With a 2-flute regular spiral design and parallel web configuration, it clears chips efficiently during through-hole and blind-hole operations.\u003c\/p\u003e\u003cp\u003eThis bit is suited for general-purpose drilling in alloy steels, aluminum, and similar workpiece materials. The short flute length of 2.875 inches and reduced overall length compared to jobber-length bits make it the preferred choice for drill press work, turret lathes, screw machines, and CNC applications where tool deflection must be minimized. It meets ASME B94.11M and ANSI specification standards, making it appropriate for both production shop and maintenance applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e43\/64 inch (0.6719 inch) diameter with a tight tolerance of +0.0000 to -0.0012 inches\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction rated for general-purpose production drilling\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned tip for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eScrew machine (short) length at 4.625 inches OAL for maximum rigidity\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with 2-flute regular spiral for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and ANSI standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose screw machine length drill bit compatible with standard straight-shank drill chucks, screw machines, turret lathes, and drill presses accepting a 0.6719-inch straight-cylindrical shank.

Ensure the machine spindle is fully powered down and at rest before changing tooling. Confirm the chuck or collet is rated for the shank diameter and that the bit is seated and tightened to the tool holders specification before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 43\/64 inch (0.6719 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6719 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.625 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eDrill Length Type\u003c\/strong\u003e: Short (Screw Machine Length)\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\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: C04630\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51714008547634,"sku":"C04630","price":67.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9ddfea39613705632c9c22d5b37f5a5.jpg?v=1788495889","url":"https:\/\/voomisupply.com\/products\/cleveland-c04630-screw-machine-drill-bit-43-64-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
