Sized at 0.0160 inches in diameter, it features a 118-degree standard point angle and a two-flute regular spiral design with a tapered web configuration and web thinning for improved chip clearance and entry performance. The straight-cylindrical shank measures 0.0160 inches in diameter and the overall length is 0.875 inches (7\/8 inches). Right-hand cutting direction is standard. This bit is suited for general purpose drilling applications and is installed by machinists, maintenance technicians, and tradespeople working with small-diameter precision holes.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for general purpose drilling in light metals, plastics, and similar materials where small-diameter wire gauge size holes are required. The wire size 78 designation corresponds to 0.0160 inches, placing it in the 0.0000 to 0.0500 inch size range. It is commonly used in light fabrication, instrument work, electrical panel work, and precision maintenance tasks. The jobber length format provides a balance of reach and rigidity for bench drill press and hand drill applications. Sold individually, with a minimum order quantity of 12 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 78 at 0.0160 inches diameter for small-diameter precision drilling\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for general purpose use across light metals and plastics\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web thinning for improved penetration and reduced walking\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral with tapered web for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 0.0160 inches for compatibility with standard drill chucks\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating buildup to affect tolerance in tight-diameter applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general purpose jobber length drill bit for use in standard drill chucks and drill presses that accommodate straight-cylindrical shanks in the 0.0000 to 0.0500 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove drill bits only with the drill press or hand drill fully powered down and the chuck key removed from the chuck. Secure the shank firmly in the chuck before operation to prevent slippage at small diameters. For wire gauge sizes this small, use a drill press with a feed stop or a steady hand to avoid bit deflection and breakage. Consult applicable workplace safety standards when operating high-speed rotating tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 78\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0160 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.875 inches (7\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0160 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 84578335\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51752916812082,"sku":"84578335","price":102.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f1ed786c92f499baf12915c79495a64.jpg?v=1788931092","url":"https:\/\/voomisupply.com\/products\/hertel-84578335-jobber-drill-bit-wire-78-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
