Built from high speed steel (HSS) with a bright, uncoated finish, it features a 135-degree split point that self-centers on contact and reduces walking without a center punch. The web-thinned, tapered web construction lowers thrust requirements and improves chip evacuation. Overall length is 3.0 inches with a 1.875-inch flute length. This is a heavy-duty grade bit suitable for production and maintenance drilling environments where consistent hole quality matters.\u003c\/p\u003e\u003cp\u003eThe C11681 is rated for drilling steel, aluminum, and general non-ferrous workpieces. Its 0.1440-inch diameter corresponds to a No. 27 wire gauge, a size commonly used for tapping and clearance holes in light to medium metalworking, sheet metal fabrication, and mechanical assembly. The right-hand, regular spiral flute geometry suits general-purpose drilling on drill presses, hand drills, and CNC applications at standard cutting speeds for HSS tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 27 wire size with 0.1440-inch decimal diameter and tight tolerance of -0.0007 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e135-degree split point self-centers and reduces thrust on entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web for lower drilling resistance and improved chip flow\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction, bright\/uncoated finish for general-purpose metalworking\u003c\/li\u003e\n\u003cli\u003eRight-hand regular spiral flute, straight cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type B specification, heavy-duty grade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-length replacement drill bit for use in any drill press, hand drill, or CNC spindle accepting a 0.1440-inch straight shank.

Ensure the shank is fully seated and the chuck is tightened securely before operation. Select appropriate cutting speed and feed rate for the workpiece material and bit diameter per standard HSS machining references. Inspect the cutting edges for wear before reuse; a worn split point increases thrust and reduces hole accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1440 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 Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel (HSS)\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: Regular Spiral, Right Hand\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: 1.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0 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: 0.1440 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.125 inches\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: -0.0007 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2222\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Aluminum, Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C11681\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51701554938162,"sku":"C11681","price":45.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e56d334f62ba9a2345c4921163ca3c2b.jpg?v=1788401372","url":"https:\/\/voomisupply.com\/products\/cleveland-c11681-jobber-drill-bit-no-27-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
