The 135-degree split point reduces walking at contact and requires less thrust than a standard 118-degree tip. At 3.125 inches overall length with a 2-inch flute, this bit handles the depth demands of typical jobber applications. The straight-cylindrical shank seats securely in standard 3-jaw chucks. This is a professional-grade drill bit suited for machinists, maintenance technicians, and trade professionals working with hand drills, drill presses, and CNC equipment.\u003c\/p\u003e\u003cp\u003eThe 66694225 is sized to wire gauge No. 23, which corresponds to a decimal diameter of 0.1540 inches. This size is commonly used in precision holemaking tasks such as tap-size drilling, pilot hole work, and sheet metal fabrication across HVAC, electrical, plumbing, and mechanical service trades. The two-flute spiral design with a tapered, web-thinned construction provides efficient chip evacuation and reduced heat buildup during continuous use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point reduces drill walk and lowers required thrust force\u003c\/li\u003e\n\u003cli\u003eTiN coating extends tool life and reduces friction during cutting\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web construction improves penetration efficiency\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry supports consistent chip clearing\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eNAS specification designation confirms heavy-duty grade construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length drill bit fitting standard 3-jaw drill chucks that accept a 0.1540-inch straight shank, compatible with hand drills, drill presses, and CNC spindles across general holemaking applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove drill bits only when the drill or drill press is fully powered down and the chuck is stationary. Secure the shank fully in the chuck jaws before operation to prevent slippage or runout. Use appropriate cutting fluid or lubrication when drilling ferrous metals to extend bit life. Inspect the cutting edges and TiN coating before each use and replace the bit if chipping or excessive wear is present.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 23\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1540 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\u003eFlute Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1540 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\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: 66694225\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51742239129906,"sku":"66694225","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c0a857073697fb303d244a8fad403258.jpg?v=1788836116","url":"https:\/\/voomisupply.com\/products\/hertel-66694225-jobber-drill-no-23-hss-tin-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
