Built for heavy-duty holemaking, this bit features a 135-degree split point that reduces walking and allows self-centering entry without a center punch. The oxide and TiN coating improves surface hardness and heat resistance, extending tool life in demanding materials. The straight-cylindrical shank is compatible with standard three-jaw drill chucks. With an overall length of 3-5\/8 inches and a flute length of 2-7\/16 inches, this is a standard jobber-series proportioned bit suited for general-purpose production drilling.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for holemaking applications in ferrous metals, stainless steel, high-nickel alloys, and other hard-to-machine materials where cobalt grade tooling is appropriate. The regular spiral flute geometry promotes chip evacuation in both hand-held and machine-mounted drilling setups. It is commonly used by machinists, maintenance technicians, pipefitters, and metalworkers in shop and field environments. The web-thinned, tapered web design reduces thrust requirements, making it well suited for both drill press and power hand-tool use where operator fatigue and feed pressure are factors.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge No. 9 size, 0.196 inches decimal diameter\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning for self-centering entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eCobalt construction rated for heavy-duty drilling in hard and abrasion-resistant materials\u003c\/li\u003e\n  \u003cli\u003eOxide and TiN dual coating for improved heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, regular spiral flute for consistent chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard jobber-series drill bit compatible with any three-jaw chuck or collet system accepting a 0.196-inch straight-cylindrical shank, suitable for use in drill presses, CNC drilling machines, and power hand drills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and serviced by machinists, maintenance mechanics, and trade professionals performing metal drilling operations. Secure the shank firmly in the chuck and verify concentricity before drilling to prevent premature wear or bit breakage. Appropriate cutting fluid or coolant is recommended when drilling ferrous metals to manage heat buildup, even though coolant-through is not supported on this bit. Follow shop safety protocols including eye protection and secure workpiece clamping before operation.\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. 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.196 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide and TiN\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eFlute Length\u003c\/strong\u003e: 2-7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.196 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Jobber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.295 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: 04138566\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739085439282,"sku":"04138566","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e3904b0189a48c9d430eeeb1ef6bf74.jpg?v=1788809148","url":"https:\/\/voomisupply.com\/products\/hertel-04138566-cobalt-jobber-drill-no-9-0-196-in","provider":"Voomi Supply","version":"1.0","type":"link"}
