Sized at wire gauge No. 73 (0.0240 inches \/ 0.61 mm), it features a 118-degree drill point angle and a fast spiral with a 35-degree helix angle for efficient chip evacuation. The tapered web configuration improves rigidity and reduces walking at entry. A bright polished finish minimizes friction and buildup during cutting. This bit is intended for use by machinists, electronics manufacturing technicians, and skilled tradespeople requiring tight-tolerance, small-diameter drilling.\u003c\/p\u003e\n\u003cp\u003eThe 30002400 is suited for drilling cast iron, non-ferrous metals, and steel, making it applicable across PCB manufacturing, precision metalworking, and light fabrication environments. Its heavy-duty grade solid carbide construction supports repeated use in production settings where consistency and hole quality are critical. With a 3\/8-inch flute length and 1-1\/2-inch overall length, it fits standard drill chucks and CNC spindles designed for small-diameter tooling. Right-hand cutting direction is standard for conventional drill press and CNC drilling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge No. 73 diameter: 0.0240 inches (0.61 mm) for precise small-hole drilling\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction rated for heavy-duty use in cast iron, non-ferrous metals, and steel\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle with tapered web for accurate entry and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eFast spiral with 35-degree helix angle promotes effective chip removal at high RPM\u003c\/li\u003e\n  \u003cli\u003eBright polished finish reduces friction and extends tool life in production use\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, 3\/8-inch flute length, 1-1\/2-inch overall length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or production drill bit for applications requiring a No. 73 wire gauge hole diameter.

Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable tolerance, as solid carbide bits are brittle and sensitive to side-loading. Power down the spindle completely before changing tooling. Do not exceed the recommended feed rate or spindle speed for the workpiece material, as carbide bits at this diameter are susceptible to breakage under excessive force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 73\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0240 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 0.61 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: 0.0240 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 0.61 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length (Inch)\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length (mm)\u003c\/strong\u003e: 9.53 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\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy-Duty\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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to +0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: 30002400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736113283378,"sku":"30002400","price":25.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d94079db2097f7cdb0a96aa07eab8575.jpg?v=1788775958","url":"https:\/\/voomisupply.com\/products\/hertel-30002400-circuit-board-drill-bit-no-73-0-61mm","provider":"Voomi Supply","version":"1.0","type":"link"}
