Built from high-speed steel with an oxide coating for reduced friction and extended tool life, this bit features a 118-degree standard point angle suited for most common drilling applications. The stubby screw machine length format  -  1-11\/16 inches overall  -  provides added rigidity over jobber-length bits, making it a reliable choice in tight clearance situations or when drill press and CNC work demands reduced deflection. Wire size 51 corresponds to a decimal diameter of 0.0670 inches. It is installed and used by machinists, tool-and-die tradespeople, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is sized at wire gauge 51 and is suited for general-purpose work in production machining, maintenance, and fabrication environments. The 2-flute regular spiral design promotes chip evacuation during through-hole and blind-hole operations. The straight-cylindrical shank fits standard drill chucks without requiring a specialized collet or adapter. It performs well in drill presses, CNC machining centers, and handheld electric drills where precision small-diameter holes are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 51 with 0.0670 inch decimal diameter for precision small-hole work\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eOxide coating reduces friction and heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose drilling without pre-spotting\u003c\/li\u003e\n  \u003cli\u003eScrew machine length overall at 1-11\/16 inches provides superior rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003e11\/16 inch flute length with 3xD flute-to-diameter ratio supports efficient chip clearing\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, straight-cylindrical shank for compatibility with standard drill chucks\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 standard drill chucks accepting straight-cylindrical shanks across drill presses, manual mills, and CNC equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists and maintenance technicians in standard three-jaw chucks or collet holders. Ensure the workpiece is securely fixtured before beginning the cut, and confirm the drill is running at an appropriate speed for the workpiece material and bit diameter. Do not exceed the rated capacity of the chuck or spindle. Worn or chipped cutting edges should be reground or the bit replaced to maintain hole accuracy and avoid tool breakage.\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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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: Oxide\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\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\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 61699401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51741893624114,"sku":"61699401","price":42.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82fe06fb294a6dcbbedbfb46499eb68d.jpg?v=1788834121","url":"https:\/\/voomisupply.com\/products\/hertel-61699401-screw-machine-drill-bit-wire-51-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
