It is built for precision drilling in printed circuit board fabrication and fine-component manufacturing environments. The bit features a 118-degree drill point angle, a fast spiral flute design, and a tapered web configuration that promotes chip evacuation and reduces heat buildup at small diameters. Right-hand cutting direction and a 35-degree helix angle support clean, accurate entry in thin or laminated materials. This bit is installed and used by machining and electronics manufacturing professionals requiring tight tolerances in miniature-diameter drilling.\u003c\/p\u003e\u003cp\u003eThis circuit board drill bit is suited for drilling applications in cast iron, non-ferrous metals, and steel, in addition to its primary use in printed circuit board materials. The fast spiral geometry makes it well-suited for production environments where hole quality and cycle time both matter. With an overall length of 1.5 inches and a flute length of 0.625 inches (15.88mm), it is compact and designed for use in CNC drilling machines and precision drill presses common in electronics assembly and light machining operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge No. 56 diameter: 0.0465 inches (1.18mm) for precision miniature drilling\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for hardness, wear resistance, and dimensional stability\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle for controlled entry and minimal material deformation\u003c\/li\u003e\n\u003cli\u003eFast spiral flute with tapered web promotes chip clearance in fine-diameter work\u003c\/li\u003e\n\u003cli\u003e35-degree helix angle supports clean hole finish in circuit board and metallic substrates\u003c\/li\u003e\n\u003cli\u003eBright polished finish reduces friction and aids chip flow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use circuit board drill bit for CNC drilling machines and precision drill presses accepting a 1.18mm shank diameter.

Ensure the drill chuck or collet is clean and properly torqued to the machine manufacturer's specification before operation. Verify spindle speed and feed rate settings are appropriate for the workpiece material and bit diameter before engaging the cut. Inspect the bit for chipping or wear before each use, as solid carbide bits at small diameters are brittle and should not be used if visibly damaged.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0465 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 1.18mm\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: 0.0465 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 1.18mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length (Inch)\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length (mm)\u003c\/strong\u003e: 15.88mm\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: 38.10mm\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 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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.45 pounds\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: 30004650\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730688377138,"sku":"30004650","price":23.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ded447de7dc6919b42dce25863040abd.jpg?v=1788721435","url":"https:\/\/voomisupply.com\/products\/hertel-30004650-circuit-board-drill-bit-no-56-1-18mm","provider":"Voomi Supply","version":"1.0","type":"link"}
