Sized to wire gauge 4 (0.2090 inches decimal), this bit is manufactured from high-speed steel (HSS) with a bright, uncoated finish and a standard 118-degree point angle. The short overall length of 2-3\/8 inches reduces deflection and improves hole accuracy in production drilling environments. It features a two-flute, regular spiral design with a straight-cylindrical shank and a web-thinned tip for easier penetration. Licensed machinists, tool-and-die professionals, and metal fabrication shops are the primary users of this tooling.\u003c\/p\u003e\n\u003cp\u003eThe C04487 is suited for general-purpose drilling in alloy steel and aluminum workpieces. Its Series 2120 designation and ASME B94.11M compliance make it a standard choice for CNC machining centers, drill presses, and hand-operated production rigs where stub-length bits are specified. The 1-1\/4-inch flute length accommodates typical depth requirements for through-holes and shallow blind holes in sheet metal and structural stock. Right-hand cut geometry pairs with conventional clockwise spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 4 (0.2090 inches decimal) with a diameter tolerance of +0.0000 to -0.0007 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides heat resistance in general-purpose metal drilling applications\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned tip reduces thrust and improves penetration\u003c\/li\u003e\n  \u003cli\u003eScrew machine (short) length of 2-3\/8 inches overall increases rigidity and reduces run-out\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows easy visual inspection for wear and regrinding\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M standard for twist drill dimensions and tolerances\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 for use in CNC machining centers, drill presses, and production fixtures requiring a straight-cylindrical shank in wire gauge sizing.

Ensure the drill press or machining center spindle is at a complete stop before changing tooling. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting this bit does not have coolant-through capability. Verify spindle speed and feed rate are appropriate for the workpiece material and hole diameter before beginning the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2090 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches (2-3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches (1-1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.125 inches (1-1\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2090 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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\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 Length Type\u003c\/strong\u003e: Short (Screw Machine)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 inches\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  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\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: C04487\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51698443682098,"sku":"C04487","price":48.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5898bd79ab0eb2c86b7e65041dbde40.jpg?v=1788362943","url":"https:\/\/voomisupply.com\/products\/cleveland-c04487-screw-machine-drill-bit-wire-4-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
