Built to wire gauge No. 46 (0.0810 inches \/ 2.06 mm), the bit features a 130-degree drill point angle and a fast spiral flute configuration with a 35-degree helix angle. The tapered web and bright polished finish support clean, accurate hole entry and chip evacuation. Right-hand cutting direction and solid carbide construction make this bit well-suited for production environments where consistency and tool life matter. Licensed trade professionals and shop technicians handling electronics assembly, PCB work, or precision machining rely on this geometry for repeatable results.\u003c\/p\u003e\u003cp\u003eThis drill bit is appropriate for use in circuit board drilling applications as well as precision hole work in alloy steel, carbon steel, cast iron, high temperature alloys, stainless steel, and titanium. The 0.125-inch (1\/8-inch) shank diameter fits standard drill chucks and CNC spindle collets used in bench drilling and automated drilling operations. With an overall length of 1.5 inches and a flute length of 0.375 inches (3\/8 inch), the bit is sized for controlled depth in thin-stock and multi-layer board drilling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size No. 46 diameter: 0.0810 inches (2.06 mm) with tolerance of -0.0003 to +0.0000 inches\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle for clean entry and reduced thrust in thin materials\u003c\/li\u003e\n\u003cli\u003eFast spiral, 35-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eTapered web configuration reduces walking and improves hole accuracy\u003c\/li\u003e\n\u003cli\u003eBright polished finish minimizes friction and material buildup on the cutting edge\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit for applications requiring a No. 46 wire-size, 1\/8-inch shank solid carbide bit in standard drill chucks and CNC collet systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by machinists, electronics technicians, and precision drilling operators using compatible drill presses, CNC drilling equipment, or handheld drill stations. Ensure the spindle and collet are clean and properly secured before seating the 1\/8-inch shank. Solid carbide tooling is brittle — avoid side loading, cross-drilling angles, or excessive feed pressure that can cause fracture. Follow machine manufacturer speed and feed recommendations for carbide tooling in the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 46\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0810 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 2.06 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch) \/ 3.18 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.375 inches (3\/8 inch) \/ 0.4800 inches decimal\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\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright Polished\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0003 to +0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Cast Iron, High Temperature Alloy, Stainless Steel, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 30208100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732353155378,"sku":"30208100","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9c43f91931a0221c3e4a59ad862e5823.jpg?v=1788741964","url":"https:\/\/voomisupply.com\/products\/hertel-30208100-no-46-solid-carbide-circuit-board-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
