Sized at wire gauge number 65 with a decimal diameter of 0.0350 inches (0.89 mm), the bit features a 118-degree point angle and a fast spiral with a 35-degree helix angle for efficient chip evacuation. The bright polished finish reduces friction and heat buildup during operation. Overall length is 1.5 inches, with a flute length of 0.625 inches. A tapered web configuration adds rigidity while maintaining the tight tolerances required for small-diameter drilling.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production and repair drilling in circuit board manufacturing, electronics assembly shops, and precision machining environments. It performs in cast iron, non-ferrous metals, and steel, making it applicable beyond PCB work to any application demanding a tight-tolerance, small-diameter carbide drill. Right-hand cut direction is standard for conventional drill press and CNC spindle use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 65 with 0.0350-inch decimal diameter and 0.89 mm metric equivalent\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle for clean entry in hard and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for hardness, wear resistance, and dimensional stability\u003c\/li\u003e\n\u003cli\u003eFast spiral with 35-degree helix angle promotes chip clearance in deep or stacked material drilling\u003c\/li\u003e\n\u003cli\u003eBright polished finish reduces friction and extends tool life in fine-tolerance operations\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of -0.0005 to +0.0000 inches ensures precision hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill press chucks, CNC drilling machines, and precision spindles accepting a 0.0350-inch shank diameter, and suited for drilling cast iron, non-ferrous metals, and steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this bit should be performed by qualified machinists or electronics manufacturing technicians familiar with small-diameter carbide tooling. Ensure the spindle and chuck are rated for the shank diameter before securing the bit. Carbide bits are brittle and susceptible to breakage from lateral loading or excessive feed pressure — use appropriate feed rates and RPM settings for the material and bit diameter. Inspect the cutting edges before each use and replace any bit showing chipping or wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 65\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0350 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 0.89 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0350 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 0.89 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\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\u003eFlute Length (Inch)\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length (mm)\u003c\/strong\u003e: 15.88 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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to +0.0000 inches\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: 0.006 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: 30003500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735647977778,"sku":"30003500","price":25.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da36ed5ee24849592e7705c54e28498c.jpg?v=1788773439","url":"https:\/\/voomisupply.com\/products\/hertel-30003500-circuit-board-drill-bit-size-65-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
