It carries a wire gauge size of No. 11, which equals 0.1910 inches in decimal, and measures 3.5 inches overall with a 2.3125-inch flute length. The 135-degree split point reduces walking on entry and requires less thrust than a conventional 118-degree point. A titanium nitride (TiN) coating increases surface hardness and extends tool life under high-cycle conditions. Licensed HVAC, plumbing, electrical, and mechanical contractors, as well as machinists and fabricators, reach for this bit when drilling structural steel, brackets, and sheet metal assemblies.\u003c\/p\u003e\n\u003cp\u003eThe 53940 fits standard drill chucks using its 0.1910-inch straight cylindrical shank. The parabolic flute geometry evacuates chips aggressively, making it well-suited for deep-hole drilling in steel alloy where chip packing is a concern. Its tapered web and web-thinned point lower cutting resistance at the center of the bit, which reduces heat buildup and prolongs edge life. This bit is sold individually and is intended for use in bench drill presses, magnetic drills, or hand-held power drills wherever a No. 11 wire-gauge hole is required in ferrous material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces entry walking and lowers thrust requirements on steel alloy\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design accelerates chip evacuation in deep-hole applications\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating increases surface hardness and extends cutting life\u003c\/li\u003e\n  \u003cli\u003eTapered, web-thinned construction lowers cutting resistance and reduces heat generation\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty grade high speed steel construction rated for production-level use\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with straight 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 an OEM-style drop-in replacement for No. 11 wire-gauge jobber length drill bits in any standard drill chuck accepting a 0.1910-inch straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMachinists, pipefitters, and electricians typically install this bit in a keyed or keyless chuck on a drill press or hand-held power drill. Secure the shank fully in the chuck before operation and confirm chuck key removal before powering the spindle. Use cutting fluid or a compatible cutting oil when drilling steel alloy to manage heat and extend edge life. Inspect the cutting edges for wear or chipping between uses, as a dull bit increases thrust load and can cause workpiece damage or bit breakage.\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. 11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1910 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1910 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1875 inches\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\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: -0.0007 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150DHT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 53940\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51729907843378,"sku":"53940","price":109.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f29e126c0df8e34e359dc839ae4cfe4.jpg?v=1788709806","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-53940-jobber-drill-bit-no-11-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
