Built to No. 62 wire gauge size, it measures 0.0380 inches (0.97 mm) in diameter with a 1\/8-inch shank diameter and a 1-1\/2-inch overall length. The 130-degree drill point angle and fast spiral geometry promote clean entry and efficient chip evacuation in small-diameter, high-precision drilling. A tapered web configuration adds rigidity at the cutting edge, reducing deflection in fine-diameter work. The bright polished finish minimizes friction and helps maintain dimensional accuracy across production runs. This bit is sized and constructed for use by machinists, electronics fabricators, and precision drilling technicians.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling small-diameter holes in circuit boards and other precision components. The fast spiral and 35-degree helix angle make it effective across a range of workpiece materials including alloy steel, carbon steel, cast iron, stainless steel, high-temperature alloy, and titanium. It fits standard 1\/8-inch shank collets commonly used in CNC drilling machines, PCB drill presses, and precision benchtop drill setups. The 3\/8-inch flute length accommodates typical board stack thicknesses and thin-section metalwork. Right-hand cutting direction is standard for conventional spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 62 wire size — 0.0380 inches (0.97 mm) diameter for fine-tolerance hole placement\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle optimized for clean penetration in circuit board and thin-section applications\u003c\/li\u003e\n\u003cli\u003eFast spiral with 35-degree helix angle for efficient chip removal in small-diameter drilling\u003c\/li\u003e\n\u003cli\u003eTapered web configuration reduces deflection and improves cutting stability\u003c\/li\u003e\n\u003cli\u003eBright polished finish reduces friction and extends tool life in repetitive production use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or stock drill bit for use in standard 1\/8-inch shank collet systems on CNC PCB drill presses and precision drilling equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this bit should be performed by qualified machinists or electronics fabrication technicians familiar with small-diameter carbide tooling. Secure the 1\/8-inch shank fully in the collet before operation and verify runout is within tolerance, as carbide bits at this diameter are brittle and sensitive to lateral loading. Power down and de-energize the spindle completely before changing bits. Avoid using this bit in hand-held drilling applications where axis control cannot be maintained.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 62\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0380 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 0.97 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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0003 to +0.0000 inches\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: Alloy Steel, Carbon Steel, Cast Iron, High Temperature Alloy, Stainless Steel, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.45 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: 30203800\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727361933618,"sku":"30203800","price":17.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d45870c5564ad546abd10740bc7bb623.jpg?v=1788676737","url":"https:\/\/voomisupply.com\/products\/hertel-30203800-circuit-board-drill-bit-no-62-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
