Built to wire gauge size 50 with a decimal diameter of 0.0700 inches (1.78 mm), this bit features a fast spiral flute geometry and a 118-degree drill point angle for clean, accurate hole entry. The solid carbide construction and bright polished finish support tight tolerance drilling. The tapered web configuration adds stability at depth, and the right-hand cutting direction suits standard drill press and CNC spindle setups. This bit is typically installed and used by electronics fabricators, precision machinists, and maintenance technicians working with small-diameter through-holes.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in circuit board drilling, light sheet metal work, and precision machining operations involving cast iron, non-ferrous metals, and steel. The fast spiral flute with a 35-degree helix angle promotes efficient chip evacuation in shallow-depth, small-diameter bores. The compact overall length of 1.5 inches and 0.625-inch flute length make it a practical choice for bench-top drill presses, CNC drilling machines, and PCB routing stations where tight clearance and repeatability matter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for wear resistance and dimensional stability in small-diameter drilling\u003c\/li\u003e\n  \u003cli\u003eWire size 50 diameter — 0.0700 inches (1.78 mm) — with a tight tolerance of -0.0005 to +0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle for clean entry in metallic and PCB substrates\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute with 35-degree helix angle for effective chip clearance\u003c\/li\u003e\n  \u003cli\u003eBright polished finish reduces built-up edge and aids chip flow\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration improves rigidity and reduces deflection at depth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard CNC PCB drilling machines, bench-top drill presses, and precision drilling stations that accept a 1.78 mm (0.0700 inch) straight shank.

Power down and lock out the spindle before loading or unloading the bit. Secure the shank fully in the collet or chuck to the manufacturer-recommended depth before operation. Inspect the cutting edges for chipping or wear before each use, as solid carbide bits at this diameter are brittle and sensitive to side loading.\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: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0700 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 1.78 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0005 to +0.0000 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\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\u003eShank Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0700 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 1.78 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.625 inches (15.88 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\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\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metals, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 30007000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744873873714,"sku":"30007000","price":20.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/19d698f8d7360126a4a060529d7e215d.jpg?v=1788861815","url":"https:\/\/voomisupply.com\/products\/hertel-30007000-circuit-board-drill-bit-size-50-1-78mm","provider":"Voomi Supply","version":"1.0","type":"link"}
