It features a 3\/8 inch (0.3750 inch) diameter with a standard 118-degree point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation at the start of the cut. The bright, uncoated finish suits applications where coating compatibility with the workpiece material is a concern. At 5.0 inches overall length with a 3.625 inch flute, this bit fits standard drill chucks and magnetic drill presses used by trade professionals daily.\u003c\/p\u003e\n\u003cp\u003eThis jobber drill bit is suited for metal fabrication, mechanical contracting, and maintenance work across industrial and commercial jobsites. The straight cylindrical shank accepts standard three-jaw drill chucks. The right-hand, regular spiral flute geometry handles steel, cast iron, non-ferrous metals, and similar materials where a carbide-tipped edge outlasts standard high-speed steel in abrasive or interrupted-cut conditions. It is a single-piece unit packaged individually, making it a direct replacement or add-to-kit option for trade toolboxes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide-tipped cutting edge for extended tool life in abrasive and hard materials\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating interaction with workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral flute for efficient chip clearance\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical 3\/8 inch shank fits standard drill chucks without an adapter\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0010 inches for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with any standard three-jaw drill chuck accepting a 3\/8 inch straight cylindrical shank, including benchtop drill presses, hand drills, and magnetic base drills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, pipefitters, and general trade mechanics. Secure the straight shank firmly in the chuck and verify concentricity before drilling. Always wear appropriate eye protection and secure the workpiece before beginning a cut. Follow applicable OSHA and facility safety standards for rotating cutting tools, and never exceed the rated speed range for the drill press or hand tool in use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Carbide-Tipped\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright, Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.0 inches (127.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.625 inches (92.08 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.375 inches (34.92 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral, Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\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: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 77661\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51730202984754,"sku":"77661","price":81.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/419cd6f91b78217d98fcfca7bdb96e12.jpg?v=1788713267","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-77661-carbide-tipped-jobber-drill-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
