Ground to a No. 41 wire gauge size, it measures 0.0960 inches (2.44 mm) in diameter with a matching 0.0960-inch shank. The 118-degree drill point and fast spiral flute geometry promote clean entry and efficient chip evacuation. A bright polished finish reduces friction and helps maintain cutting edge life. This bit is suited for use in CNC drilling equipment and precision drill presses operated by machinists, electronics technicians, and fabrication professionals.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for drilling cast iron, non-ferrous metals, and steel in applications that demand consistent hole size and surface finish. Its tapered web configuration adds strength at the tip while the 35-degree helix angle supports fast chip removal at higher spindle speeds. Typical install scenarios include PCB drilling, instrument panel fabrication, and small-diameter production drilling where hole location and diameter tolerance are critical. The tight diameter tolerance of -0.0005 to +0.0000 inches ensures repeatable, on-size holes across production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 41 wire gauge size, 0.0960 inches (2.44 mm) diameter with matching shank diameter\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for superior hardness and wear resistance in small-diameter drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle for accurate starts and clean hole entry\u003c\/li\u003e\n  \u003cli\u003eFast spiral, 35-degree helix angle promotes rapid chip evacuation\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration adds tip strength and reduces walking\u003c\/li\u003e\n  \u003cli\u003eBright polished finish minimizes friction and extends cutting life\u003c\/li\u003e\n  \u003cli\u003eTight diameter tolerance of -0.0005 to +0.0000 inches for precision, repeatable holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron, non-ferrous metals, and steel. Suitable for CNC PCB drilling machines and precision drill presses that accept a 0.0960-inch straight shank. Verify collet or chuck size before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or fabrication technicians familiar with small-diameter carbide tooling. Carbide is brittle — avoid side loads, interrupted cuts without proper feed rate control, and re-chucking without confirming runout. Ensure the spindle and collet are clean and free of debris before seating the shank. Match spindle speed and feed rate to the workpiece material to prevent tip 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. 41\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0960 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 2.44 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\u003eShank Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0960 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 2.44 mm\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\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: -0.0005 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\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metals, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright Polished\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 30009600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749622481202,"sku":"30009600","price":22.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f3e3a04383e94c52a247555822208b2.jpg?v=1788908474","url":"https:\/\/voomisupply.com\/products\/hertel-30009600-circuit-board-drill-bit-no-41-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
