It carries a wire gauge size of 19, which corresponds to a decimal diameter of 0.1660 inches (4.22 mm), and features a 118-degree point angle suited for accurate entry on flat workpiece surfaces. The bright, uncoated finish preserves the carbide substrate for maximum hardness and wear resistance. With an overall length of 1.5 inches and a fast spiral flute design, this bit moves chips efficiently and maintains hole geometry in demanding materials.\u003c\/p\u003e\u003cp\u003eThis bit is intended for use in CNC drilling equipment, drill presses, and precision hand-held power tools where tight hole tolerances are required. It is well suited for drilling cast iron, non-ferrous metals, and steel, making it appropriate for electronics manufacturing environments as well as general metalworking shops. The tapered web and 35-degree helix angle contribute to stable cutting performance across these material groups. Trade machinists, electronics fabricators, and precision job shops are the primary installers and users of this bit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for high hardness and extended tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003eWire gauge size 19 with a 0.1660-inch (4.22 mm) cutting diameter\u003c\/li\u003e\n\u003cli\u003e118-degree point angle for accurate, self-centering entry on flat stock\u003c\/li\u003e\n\u003cli\u003eFast spiral flute with 35-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eTapered web configuration improves rigidity and reduces deflection\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a wide range of cutting fluids and dry cutting setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard wire-gauge circuit board drill bit suitable for use in CNC PCB drilling machines and precision drill presses that accept a 0.1660-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified machinists or electronics fabrication technicians familiar with CNC tooling and precision drill setups. Secure the shank fully in the collet or chuck before operation and confirm runout with a dial indicator where tolerances are critical. Use appropriate cutting fluid or coolant for the material being drilled. Inspect the cutting edges before each use, as solid carbide is brittle and susceptible to chipping if dropped or improperly stored.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 19\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1660 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 4.22 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1660 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 4.22 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length (Inch)\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length (mm)\u003c\/strong\u003e: 19.05 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (Inch)\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (mm)\u003c\/strong\u003e: 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\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\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\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\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.55 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 30016600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737607373106,"sku":"30016600","price":36.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9f077a4b39dde57a56a9d32223872d7.jpg?v=1788791300","url":"https:\/\/voomisupply.com\/products\/hertel-30016600-circuit-board-drill-bit-size-19-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
