Built to wire gauge size No. 20, this bit measures 0.1610 inches (4.09 mm) in diameter with a matching shank diameter of 0.1610 inches. The fast spiral flute geometry and 35-degree helix angle promote efficient chip evacuation, reducing heat buildup and minimizing the risk of breakthrough burrs. A bright polished finish lowers friction and contributes to extended tool life in production drilling environments. Licensed HVAC, electrical, and precision manufacturing technicians working on control board assemblies or electronic subcomponents will find this bit suited to tight-tolerance work.\u003c\/p\u003e\n\u003cp\u003eThis bit is sized for No. 20 wire gauge applications and is well-suited for drilling through cast iron, non-ferrous metals, and steel in addition to circuit board substrates. With a 0.75-inch flute length and a compact 1.5-inch overall length, it fits standard high-speed drilling spindles and benchtop drill presses used in electronics manufacturing and repair shops. The tapered web configuration adds rigidity at the cutting tip, making it appropriate for both production runs and single-unit repair tasks where dimensional accuracy is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in precision drilling\u003c\/li\u003e\n  \u003cli\u003eNo. 20 wire size, 0.1610 inches (4.09 mm) cutting diameter\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute with 35-degree helix angle for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle for clean entry on metallic and composite substrates\u003c\/li\u003e\n  \u003cli\u003eBright polished finish reduces friction and aids chip flow\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration improves bit stability and cutting accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production drill bit for applications requiring a No. 20 wire gauge solid carbide circuit board drill bit compatible with standard straight-shank drill chucks and high-speed spindles.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or technicians familiar with precision drilling equipment. Secure the bit firmly in a compatible chuck rated for the shank diameter before operation. Always verify spindle speed settings are appropriate for the workpiece material and bit diameter before drilling. Inspect the cutting edge for chipping or wear before each use, as carbide tooling is brittle and should not be forced into hard material at excessive feed rates.\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: No. 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1610 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 4.09 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1610 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 4.09 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches (38.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to +0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metals, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright Polished\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: 30016100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746890940722,"sku":"30016100","price":32.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae80d6e7742025919856869dc3245907.jpg?v=1788874386","url":"https:\/\/voomisupply.com\/products\/hertel-30016100-circuit-board-drill-bit-no-20-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
