Manufactured from high-speed steel with a bright, uncoated finish, it carries a wire gauge size of 51, equivalent to 0.0670 inches in decimal. The 118-degree standard point angle and web-thinned tip reduce entry force and help center the bit on the workpiece. At 1-11\/16 inches overall length, the short flute design adds rigidity and minimizes deflection in drill press, turret lathe, and screw machine applications. A licensed HVAC tech, machinist, or tool-and-die professional will recognize this as a standard stub drill for close-tolerance work.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling alloy steel and aluminum in both manual and automated setups. The straight-cylindrical shank at 0.0670 inches diameter seats directly in standard chucks and collets without adapters. The 11\/16-inch flute length and 1-inch shank length keep the tool compact for tight clearance drilling. Regular spiral geometry provides efficient chip evacuation in through-hole and shallow-hole operations. Typical applications include production runs on CNC drill presses, manual drill presses, and turret lathes where stub-length rigidity is preferred over jobber-length reach.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 51 (0.0670 inches decimal) with diameter tolerance of +0.0000 to -0.0005 inches for close-fit hole production\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned tip for reduced thrust and self-centering entry\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for heat resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish allows visual wear inspection during use\u003c\/li\u003e\n  \u003cli\u003eStub-length body (1-11\/16 inches OAL) maximizes rigidity and minimizes deflection in screw machine and drill press setups\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M dimensional standards for consistent interchangeability\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 three-jaw chucks and collets accepting a 0.0670-inch straight-cylindrical shank.

Secure the straight shank fully in the chuck or collet and confirm runout before starting the spindle. Always match spindle speed to the workpiece material and bit diameter using a standard speeds-and-feeds reference. Wear appropriate eye protection and secure workpieces firmly before drilling.\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: 51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0670 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11\/16 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: 0.0670 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 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\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\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: C04381\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51710821400882,"sku":"C04381","price":41.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39f526589230b1b82629e2d60fbc802e.jpg?v=1788470996","url":"https:\/\/voomisupply.com\/products\/cleveland-c04381-screw-machine-drill-bit-wire-51-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
