It is sized to wire gauge No. 9, which corresponds to a decimal diameter of 0.196 inches. The 135-degree split point reduces walking at startup and lowers thrust force during entry. With a 3-5\/8-inch overall length and a 2-7\/16-inch flute length, it fits standard drill chucks and drill presses. This bit is installed by machinists, maintenance technicians, and metalworking tradespeople who need consistent performance in hard or abrasive stock.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for ferrous and non-ferrous metals, stainless steel, cast iron, and high-strength alloys where standard high-speed steel bits wear prematurely. The right-hand spiral flute with regular helix clears chips efficiently during through-hole and blind-hole drilling operations. Web thinning reduces the chisel edge load at the point, making it particularly effective in production environments and maintenance shops where repeated drilling cycles are common. The straight cylindrical shank seats securely in both keyed and keyless chucks.\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, straight cylindrical shank of matching diameter\u003c\/li\u003e\n  \u003cli\u003eCobalt construction provides elevated heat and wear resistance compared to standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces thrust and eliminates center-punch dependency\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty grade jobber series — 3-5\/8 inches overall length suits most drill press and hand-drill applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber-series replacement drill bit for any standard chuck accepting a 0.196-inch straight cylindrical shank, covering the 0.1500 to 0.2000 inch drill bit size range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a keyed or keyless drill chuck rated for the spindle speed appropriate to the workpiece material — reduce surface footage when drilling hardened or stainless steel to avoid premature coating wear. Ensure the shank is fully seated and the chuck is tightened before operation. Use cutting fluid or coolant where the application allows, even though this bit does not feature through-coolant passages, to manage heat on extended cuts. Replace the bit if the point shows chipping or the cutting edges no longer produce clean entry holes.\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: 0.1960 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eOverall Length\u003c\/strong\u003e: 3-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1960 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Heavy Duty\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: 0.14 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: 4140034\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728491807026,"sku":"4140034","price":16.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a5e66f966b1734e78ef77c84ff2e8f6.jpg?v=1788692081","url":"https:\/\/voomisupply.com\/products\/hertel-4140034-cobalt-jobber-drill-bit-no-9-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
