Built from solid carbide, this bit delivers the rigidity and wear resistance needed for accurate, repeatable hole placement in hard and abrasive materials. It features a wire gauge size 65 cutting diameter of 0.0350 inches (0.89 mm), a 130-degree drill point angle, and a fast spiral flute design with a 35-degree helix angle and tapered web configuration. The 1\/8-inch shank diameter accommodates standard collet-style chucks. This type of tooling is typically handled by machinists, PCB fabricators, and precision metalworking technicians.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling small-diameter holes in a range of materials including alloy steel, carbon steel, cast iron, stainless steel, titanium, and high-temperature alloys. The fast spiral geometry promotes efficient chip evacuation in deep or blind-hole applications. With an overall length of 1-1\/2 inches and a 3\/8-inch flute length, this bit is sized for compact drilling setups, CNC drilling machines, and dedicated PCB drill presses where tight dimensional control is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for high rigidity and wear resistance in abrasive materials\u003c\/li\u003e\n\u003cli\u003eWire gauge size 65 cutting diameter at 0.0350 inches (0.89 mm) for precision small-hole work\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle reduces thrust force and improves entry accuracy\u003c\/li\u003e\n\u003cli\u003eFast spiral flute with 35-degree helix angle promotes chip evacuation\u003c\/li\u003e\n\u003cli\u003eTapered web configuration adds strength at the cutting tip\u003c\/li\u003e\n\u003cli\u003eBright polished finish reduces friction and aids chip flow\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct tooling option for CNC drilling machines, PCB drill presses, and precision machining centers that accept a 1\/8-inch straight shank drill bit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by machinists or PCB fabrication technicians using a collet chuck or precision drill chuck rated for the 1\/8-inch shank diameter. Ensure the spindle and workholding are completely stopped before changing tooling. Verify runout with a dial indicator before production use, as carbide bits at this diameter are sensitive to misalignment and can fracture under lateral load. Follow machine manufacturer guidelines for spindle speed and feed rate when working with solid carbide tooling at small diameters.\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 Size (Decimal Inch)\u003c\/strong\u003e: 0.0350 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 0.89 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 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\u003c\/strong\u003e: 1\/8 inch (0.1250 inches \/ 3.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3\/8 inch (0.4000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (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: -0.0003 to +0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Cast Iron, High Temperature Alloy, Stainless Steel, Titanium\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: 0.1 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: 30203500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736859672882,"sku":"30203500","price":15.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/995df574e6e928ddb2b2b67108ced81f.jpg?v=1788781186","url":"https:\/\/voomisupply.com\/products\/hertel-30203500-circuit-board-drill-bit-size-65-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
