Ground from high speed steel (HSS) with a titanium nitride (TiN) coating, this bit delivers extended tool life and reduced friction compared to uncoated HSS. The 135-degree split point is web-thinned, which minimizes walking on entry and reduces the thrust required to start a cut. At 3.125 inches overall length with a 2-inch flute, it fits standard drill chucks and drill presses used by machinists, pipefitters, electricians, and general maintenance trades.\u003c\/p\u003e\n\u003cp\u003eThis jobber drill is suited for production and maintenance drilling operations where a No. 22 wire-size hole is required. Common applications include pilot holes for tapping, clearance holes for fasteners, and layout drilling in sheet metal and structural steel. The straight-cylindrical shank seats securely in 3-jaw chucks and keyed drill press chucks without slippage. The NAS specification designation indicates this bit meets defined dimensional and performance standards for heavy-duty industrial use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiN coating extends tool life and reduces heat buildup during drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces entry thrust and prevents bit walking\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles a broad range of ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with tapered web promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard 3-jaw and keyed chucks without modification\u003c\/li\u003e\n  \u003cli\u003eNAS specification designation confirms heavy-duty dimensional compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit jobber drill for use in standard drill presses, hand drills, and CNC drilling applications requiring a No. 22 wire-size (0.1570 inch) straight-shank bit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, electricians, pipefitters, or maintenance technicians using standard drill press or hand drill equipment. Secure the straight-cylindrical shank fully into the chuck jaws and tighten with a chuck key before operation. Always use appropriate cutting fluid or lubricant when drilling ferrous metals to preserve coating life and edge geometry. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point geometry is compromised.\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. 22\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1570 inches\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: TiN (Titanium Nitride)\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\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: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.125 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: 0.1570 inches\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 Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: NAS\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: 0.12 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: 66694217\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739746009394,"sku":"66694217","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/de365838a289009873d882a452a44214.jpg?v=1788818447","url":"https:\/\/voomisupply.com\/products\/hertel-66694217-no-22-jobber-drill-bit-135-deg-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
