It cuts a 0.1440-inch diameter hole using a 135-degree split point that self-centers on contact and reduces walking on flat or curved surfaces. The regular spiral flutes are right-hand cutting and run 1.875 inches in length, with an overall length of 3 inches and a straight-cylindrical shank diameter of 0.1440 inches. The heavy-duty grade and web-thinned, tapered-web construction make it suited for production holemaking in metal fabrication, maintenance, and general trade work.\u003c\/p\u003e\u003cp\u003eThis bit is intended for holemaking in ferrous and non-ferrous metals, plastics, and composite materials encountered in HVAC, electrical, plumbing, and light fabrication trades. The jobber-length series is the standard choice for hand drills, drill presses, and CNC spindles where a general-purpose reach-to-diameter ratio is required. The No. 27 wire gauge size is commonly used for close-tolerance pilot holes, tapping operations, and sheet metal work where a precise 0.1440-inch bore is needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point self-centers and reduces walking without a center punch\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with black oxide coating for corrosion and heat resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular-spiral flutes for efficient chip evacuation in most materials\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces thrust force during drilling\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard 3-jaw chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eNAS specification designation for heavy-duty grade consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-length drill bit compatible with any 3-jaw drill chuck or collet system accepting a 0.1440-inch straight-cylindrical shank, including hand drills, drill presses, and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by machinists, maintenance technicians, or qualified tradespeople familiar with rotary cutting tools. Always secure the workpiece and confirm the chuck is fully tightened before operation. Match spindle speed to the workpiece material using standard feeds-and-speeds references for high speed steel tooling. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point geometry is compromised.\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\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.875 inches\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 Type\u003c\/strong\u003e: Straight-Cylindrical\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: Spiral (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: NAS\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: 0.1 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 84581016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737623920946,"sku":"84581016","price":47.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/54ab96e14cead4cdafb9a7b004bca8cc.jpg?v=1788791537","url":"https:\/\/voomisupply.com\/products\/hertel-84581016-no-27-hss-jobber-drill-bit-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
