It features a 118-degree drill point angle, a fast spiral flute configuration, and a tapered web for efficient chip evacuation. The bit measures 1\/64 inch (0.40 mm) in diameter with a 1\/4-inch flute length and a 1-1\/2-inch overall length. The bright polished finish reduces friction and helps maintain dimensional accuracy in tight-tolerance applications. This is a heavy-duty grade bit suited for right-hand cutting in demanding production environments.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for use in cast iron, non-ferrous metals, and steel, making it versatile across circuit board and light metalworking drilling applications. It is typically used in CNC drilling machines, micro-drill presses, and PCB routing setups where consistent hole placement and minimal runout are critical. The 0.40 mm shank diameter is sized for standard PCB drill spindle collets. Technicians and machinists working in electronics manufacturing, prototyping shops, or precision fabrication will find this bit appropriate for high-cycle drilling at small diameters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance at small diameters\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle for accurate hole initiation without walking\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute design with 35-degree helix angle promotes rapid chip removal\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration reduces thrust force during drilling\u003c\/li\u003e\n  \u003cli\u003eBright polished finish minimizes heat buildup and material adhesion\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty grade rated for cast iron, non-ferrous metals, and steel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production consumable for CNC PCB drilling equipment and micro-drill presses that accept a 0.40 mm diameter shank collet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or electronics fabrication technician familiar with micro-drill tooling. Ensure the spindle and collet are clean and free of debris before seating the bit, as contamination at this diameter can cause runout and premature breakage. Power down and lock out the machine before changing tooling. Do not exceed the recommended RPM range for the drill diameter as specified by the machine manufacturer.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 1\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0156 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 0.40 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: 0.0157 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 0.40 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length (Inch)\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length (mm)\u003c\/strong\u003e: 6.35 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (Inch)\u003c\/strong\u003e: 1-1\/2 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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0005 to +0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\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\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: 30001560\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51755019370802,"sku":"30001560","price":26.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91d235d903f7461502077c99c199fda8.jpg?v=1788950513","url":"https:\/\/voomisupply.com\/products\/hertel-30001560-circuit-board-drill-bit-1-64-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
