It features a 130-degree drill point angle and a fast spiral flute design with a 35-degree helix angle, making it well suited for clean, accurate holes in thin, dense substrates. The tapered web configuration adds rigidity and helps resist deflection at small diameters. Overall length is 1-1\/2 inches with a 3\/8-inch flute length. This bit is intended for use by machinists, electronics technicians, and PCB fabrication professionals working with precision small-diameter drilling.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for use in circuit board and precision machining applications where tight hole tolerances are required. The solid carbide construction and bright polished finish support drilling into a range of materials including alloy steel, carbon steel, cast iron, high temperature alloys, stainless steel, and titanium. It is appropriate for both manual and CNC-driven spindle applications where rigidity and positional accuracy are critical. Right-hand cutting direction is standard.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge No. 43 size with 0.0890-inch decimal diameter for precise small-bore applications\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle optimized for circuit board and thin-material entry\u003c\/li\u003e\n\u003cli\u003eFast spiral flute with 35-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eTapered web configuration reduces deflection and improves hole straightness\u003c\/li\u003e\n\u003cli\u003eBright polished finish minimizes friction and surface buildup during cutting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a precision replacement or production-use drill bit for circuit board drilling operations and small-diameter machining applications across compatible spindle toolholders accepting a 1\/8-inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by machinists or PCB fabrication technicians using drill presses, CNC routers, or dedicated PCB drilling machines that accept a 1\/8-inch shank collet or chuck. Ensure the spindle and workpiece are properly secured before operation. Verify collet runout is within acceptable limits, as excess runout at this diameter can cause bit breakage or out-of-tolerance holes. Follow machine manufacturer speed and feed guidelines for solid carbide tooling in the target material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 43\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0890 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 2.26 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\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: 30208900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730771214642,"sku":"30208900","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3ed527bd4521b2c8d8b810151a55cddf.jpg?v=1788722601","url":"https:\/\/voomisupply.com\/products\/hertel-30208900-no-43-circuit-board-drill-bit-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
