Sized to wire gauge No. 25 (0.1495 inches, 3.80 mm), it features a 118-degree drill point, a fast spiral with a 35-degree helix angle, and a tapered web configuration. The bright polished finish reduces chip adhesion and heat buildup during high-speed operation. Right-hand cutting direction is standard. This bit is intended for use by machinists, electronics technicians, and PCB fabrication professionals who require tight-tolerance, repeatable holes in thin, dense materials.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling cast iron, non-ferrous metals, and steel in addition to its primary circuit board application. The fast spiral geometry promotes efficient chip evacuation in these materials. With a 0.75 inch flute length and a 1.5 inch overall length, the 30014950 fits standard CNC drilling spindles and manual drill presses used in precision fabrication and electronics assembly environments where small-diameter, accurate holes are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge No. 25 sizing at 0.1495 inches (3.80 mm) for consistent, repeatable hole diameter\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for hardness and wear resistance in demanding materials\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle for positive starting and clean entry\u003c\/li\u003e\n\u003cli\u003eFast spiral with 35-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eTapered web configuration adds strength at the cutting tip\u003c\/li\u003e\n\u003cli\u003eBright polished finish reduces friction and heat at cutting edge\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard wire-gauge circuit board drill bit for use in CNC drilling machines, precision drill presses, and compatible spindle tooling that accepts a 0.1495 inch (3.80 mm) shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of small-diameter carbide drill bits should be performed by qualified machinists or electronics fabrication technicians. Ensure the spindle and collet are clean and free of debris before seating the shank to prevent runout. Carbide tooling is brittle and should not be used in setups with excessive vibration or lateral loading. Always confirm spindle speed and feed rate are appropriate for the workpiece material before beginning a drilling cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1495 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 3.80 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: 0.1495 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 3.80 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches (19.05 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\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright Polished\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\u003eWeight\u003c\/strong\u003e: 0.02 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: 30014950\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51752564883762,"sku":"30014950","price":29.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0fb92f5af1a32929db63fe0e87b26e2.jpg?v=1788929130","url":"https:\/\/voomisupply.com\/products\/hertel-30014950-circuit-board-drill-bit-no-25-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
