The bit is sized to wire gauge 39, with a decimal diameter of 0.0995 inches (2.53 mm), and features a 118-degree point angle for accurate entry and minimal walkout on hard substrates. The fast spiral geometry and tapered web promote efficient chip evacuation during high-speed drilling. With an overall length of 1.5 inches and a bright, uncoated finish, this bit is suited for use in CNC drilling equipment and manual precision presses operated by electronics manufacturing and tool-room technicians.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for drilling operations on cast iron, non-ferrous metals, and steel, in addition to circuit board materials. The 0.625-inch flute length provides adequate chip clearance for the shallow-depth holes common in PCB and light metalworking applications. The right-hand cut and 35-degree helix angle are standard for general-purpose CNC and benchtop drilling setups in light manufacturing and fabrication environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 39 with 0.0995-inch decimal diameter for precise PCB and metalworking hole sizes\u003c\/li\u003e\n\u003cli\u003e118-degree point angle provides clean entry on cast iron, non-ferrous metals, and steel\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers hardness and wear resistance in high-speed drilling applications\u003c\/li\u003e\n\u003cli\u003eFast spiral with 35-degree helix angle and tapered web for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish allows direct visual inspection of cutting edge condition\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 1.5-inch overall length, 0.625-inch flute length for compact precision drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC drilling machines and precision benchtop drill presses where a wire gauge 39, 0.0995-inch solid carbide bit is required for circuit board, cast iron, non-ferrous metal, or steel applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or electronics manufacturing technicians familiar with high-speed carbide tooling. Ensure the spindle and collet are clean and properly sized to accept the 0.0995-inch shank before seating the bit. Carbide tooling is brittle and susceptible to chipping from lateral loading or improper chuck engagement — avoid side pressure and confirm runout is within acceptable tolerance before beginning a drilling cycle. Power down all equipment completely before changing or inspecting tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 39\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0995 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 2.53 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0995 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 2.53 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.625 inches (15.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: 30009950\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729703633202,"sku":"30009950","price":23.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e45ba92088e978c753360c6e0b4a48f.jpg?v=1788708089","url":"https:\/\/voomisupply.com\/products\/hertel-30009950-circuit-board-drill-bit-39-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
