Solid carbide construction provides the rigidity and wear resistance required for precision drilling in printed circuit boards and other tight-tolerance electronic assemblies. The 35-degree helix angle and tapered web promote efficient chip evacuation and accurate hole placement. This bit is suited for CNC drill presses and hand-held precision drilling equipment used by electronics technicians, PCB fabricators, and machine shop professionals who need consistent, burr-free holes at small diameters.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for drilling through PCBs, thin metallic substrates, and a broad range of engineering materials including alloy steel, carbon steel, cast iron, high-temperature alloys, stainless steel, and titanium. The bright polished finish reduces friction and helps maintain cutting-edge integrity across repeated use. It is appropriate for both production drilling and prototype board work where hole diameter consistency directly affects connector and component fit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e130-degree drill point angle optimized for clean entry in circuit board and metallic substrates\u003c\/li\u003e\n  \u003cli\u003eFast spiral with 35-degree helix angle promotes rapid chip evacuation\u003c\/li\u003e\n  \u003cli\u003eTapered web design increases drill stability and reduces walking on entry\u003c\/li\u003e\n  \u003cli\u003eBright polished finish minimizes friction and heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard drill press and CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use bit for precision drilling applications requiring a No. 40 wire gauge diameter with a 1\/8 inch shank, compatible with standard drill chucks and collets accepting 0.1250 inch shank diameters.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis drill bit is installed by machinists, electronics technicians, and PCB fabricators using CNC drill presses or precision benchtop drilling equipment. Ensure the machine spindle and chuck are fully powered down before inserting or removing the bit. Secure the shank firmly in the collet or chuck to the full grip depth to prevent runout. Solid carbide bits are brittle and should not be used in handheld power drills where lateral loading can cause fracture.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0980 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 2.49 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 (0.4800 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\u003eDiameter 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: 0.5 pounds\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: 30209800\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51754749100338,"sku":"30209800","price":15.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9f3d98db7372cde5ac5f9b156e463ba8.jpg?v=1788948378","url":"https:\/\/voomisupply.com\/products\/hertel-30209800-circuit-board-drill-bit-no-40-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
