It features a 135-degree split point that reduces walking on entry and lowers thrust requirements compared to a standard 118-degree tip. The TiN (titanium nitride) coating increases surface hardness and extends tool life in production drilling applications. Two spiral flutes with a regular helix evacuate chips efficiently and help maintain consistent hole quality through the cut. This bit is built to NAS specification and rated as heavy duty grade, making it appropriate for repeat-cycle use in shop and field environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for holemaking in metal, general fabrication, and maintenance applications where a wire-gauge size hole is required. The straight-cylindrical shank fits standard 3-jaw keyless and keyed drill chucks without an adapter. The 3-5\/8-inch overall length and 2-7\/16-inch flute length make it compatible with standard drill presses, hand drills, and mill setups. It is commonly used by machinists, pipefitters, electricians, and general maintenance technicians who need a reliable wire-size bit for close-tolerance work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 7 wire gauge size  -  0.2010 inch decimal diameter\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces walk and cutting force on entry\u003c\/li\u003e\n\u003cli\u003eTiN coating for increased surface hardness and extended tool life\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction rated heavy duty grade to NAS specification\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web for reduced thrust and improved chip clearance\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without an adapter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length drill bit with a straight-cylindrical shank, compatible with any standard 3-jaw drill chuck that accepts a 0.2010-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and removed by a licensed machinist, electrician, pipefitter, or qualified maintenance technician using a standard keyed or keyless drill chuck. Ensure the drill, press, or mill is powered down and de-energized before changing tooling. Secure the shank fully in the chuck and confirm concentricity before beginning the cut. Use appropriate cutting fluid for the workpiece material to maximize tool life and hole quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2010 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\u003eFlute Length\u003c\/strong\u003e: 2-7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2010 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 Helix)\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\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\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\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: 0.12 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: 66694068\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743119933746,"sku":"66694068","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bdd5de8bc25e865f3c1d0e02bd36242d.jpg?v=1788842911","url":"https:\/\/voomisupply.com\/products\/hertel-66694068-no-7-jobber-drill-bit-135-deg-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
